Known bugs, limitations and unexpected behaviors
DaDaBIK is a PHP application which allows you to easily create a highly customizable database front-end or a database-based Web application without coding. You can use it to create in a few minutes a very basic CRUD (Create, Read, Update, Delete) database front-end or to develop a more sophisticated database application. DaDaBIK was one of the very first RAD PHP tools focused on database applications (first version released in 2001) and it is still one of the most popular.
DaDaBIK uses the PDO extension in order to support as many DBMSs as possible, at the moment it officially supports MySQL, PostgreSQL and SQLite.

- Three graphic themes, two page layouts (left menu, top menu)
- Graphic layout customizable through a documented CSS file
- Front-end in 20 languages (English, Italian, Catalan, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Hungarian, Polish, Portuguese, Rumanian, Russian, Slovak, Spanish, Swedish, Telugu).
DaDaBIK differs from software like PHPMyAdmin: it has not been created to
offer the complete administration of a database, but rather to allow the
creation of a customizable and user friendly database application. The
target of a DaDaBIK application can be the final user instead of a DB
[back to top]
- Short answer:
- DaDaBIK is a Web application written in PHP so you need a Web server (for example Apache), the PHP language and a DBMS (MySQL, PostgreSQL or SQLite are supported). If you are building your Web application on-line, your hosting provider has probably everything you need already set up. If you want to use DaDaBIK on your local computer and you don't know what a Web server is or you don't know how to install it you can download and install an application like MAMP, which automatically installs on your computer Apache, PHP and MySQL.
- Some more details:
- version >= 5.3.11 (PHP 7 is also OK). DaDaBIK can also work
with PHP >= 5.2 but contact us for details.
- with the mbstring extension enabled if you need to handle Multibyte character
- with LDAP support enabled if you need LDAP authentication
- version >= 5.0 (PDO_MYSQL PHP driver required)
- version >= 7.4 (PDO_PGSQL PHP driver required)
- version >= 3
- A pre-existent database (MySQL,
with AT LEAST ONE table, with DaDaBIK you create database
applications, not the database itself. For MySQL, a great free tool to
crate databases is MySQL
For MySQL, all the database tables must be InnoDB if you want to correctly handle transactions; DaDaBIK can also work with MyISAM tables but it cannot guarantee that transactions are processed correctly.
To prevent SQL injection vulnerabilities you have to follow these rules:
- for PostgreSQL, standard_conforming_strings must be ON (if you have a recent PostgreSQL, it should be ON by default)
- for SQLite, the database must be in UTF8. UTF8 is the character set strongly recommended also for MySQL and PostgreSQL.
- DaDABIK works with any modern browser, if you use Internet Explorer, cascade listboxes and custom required features need at least Internet Explorer 8.
DaDaBIK is not free software, it is released under the DaDaBIK license and its use requires to purchase a regular license from the Website www.dadabik.com. It is, however, open source in the sense that, after buying a license, you get the full source code of the software.[back to top]
A beginner video tutorial is available here:

- READ the requirements
- Copy all the files contained in the program_files folder in a directory of your choice under your Web server, e.g. "my_dadabik_directory"
- Open the file /include/config.php with a plain text editor and edit it (specify at least the REQUIRED parameters)
- Run the file http://yoursite.com/my_dadabik_directory/install.php to install DaDaBIK
- Open the file http://yoursite.com/my_dadabik_directory/index.php
in your browser to start using DaDaBIK.
Congratulations, you have just created your fist DaDaBIK application based on tables and views contained in the database $db_name. You can customize the application via http://yoursite.com/my_dadabik_directory/admin.php. Remember that you must set a primary key for each table managed with DaDaBIK if you want to delete and modify records; other DaDaBIK features (such as duplication checking and email alerts) also require a primary key.
You can upgrade to the latest version without loosing your application's configuration if you are running at least version 5.0:
- Replace all the old files with the new ones
- keep your upload folder if you want to save the uploaded files, but BE SURE the folder is protected, see Security section
- keep the custom_functions.php file if you have edited it
- keep your custom language files if you have created any
- Upgrade the Wordpress plugin in the Wordpress installations where you have used it (if any)
- Update your new /include/config.php file using your old configuration settings. Don't substitute the new file with the old one but MANUALLY edit the new file according to your old configuration. A good practice is to keep note of the few parameters you have changed respect to the default config.php file.
- Run the file http://your_host/your_dir/upgrade.php and follow the instructions to upgrade DaDaBIK
Please note that, due to SQLite limitations, the upgrade script is available just for MySQL and PostgreSQL.
It is not possible to upgrade from DaDaBIK BASIC to PRO/ENTERPRISE keeping your application settings.
You can, instead, upgrade from PRO to ENTERPRISE following the same instructions of the previous paragraph ("Upgrade from previous version"); this also apply if the version number is the same (e.g. you want to upgrade from DaDaBIK 7.3 Pro to DaDaBIK 7.3 ENTERPRISE).[back to top]
The configuration of DaDaBIK can be managed at two different levels.
Some general configuration parameters can be directly set from the file /include/config.php, just by opening it with a plain text editor and editing it. The file is self-explanatory. At that level you can, for example, set the database you want to manage with DaDaBIK or configure some DaDaBIK features (e.g. authentication, upload, email notices, language,...).
For a more analytic tuning you are supposed to use the admin area http://your_host/your_dir/admin.php. At this level you can:
- Choose the pages that compose your applications; a page in DaDaBIK application can consist of:
- a set of search/insert/edit forms, results grid and reporting tools related to a database table or a database view; DaDaBIK automatically creates this set for each table/view you have in your database, trying to guess the correct settings according to your schema but you can customize it (see "Configure your datagrids" and "Configure your forms" later)
- a custom HTML page (you write your custom HTML code)
- a custom PHP page (you write your custom PHP code)
- a link to an internal or external URL
- Configure your data grids, choosing between a classic tabular data grid view (default) or a custom results page completely customizable using HTML templates.
- Configure your forms: this is the core of a DaDaBIK application
configuration; here, for each field, you can set
- if the field must be included or not in search/insert/update forms and data grids
- its label
- its content (e.g. numeric, alphabetic, e-mail, url...)
- the HTML input type (e.g. textbox, dropdown menu...)
- the possible values, also driven from another table ("foreign key" lookup support)
- how the fields are arranged in each form
- custom formatting and validation functions
- search operators
- and more...
- Set the permissions (see the Permissions sections for more details)
- Synchronize your applications if you change the database schema
- How to configure a drop-down lookup field
- How to hide a field from a form
- How to manage uploaded file (images and other files) fields
- How to configure a master/details view
- How to create a pre-filtered results grid
- How to create graphic reports
- How to create a completely custom page
- What is a hook and how to add some PHP custom codes to the DaDaBIK's workflow
- How to use calculated fields
- How to share the same database between two or more DaDaBIK applications
See the related following paragraphs for further details.
Some graphic customization can be done by changing the files /include/header.php and /include/footer.php and by editing the CSS file /css/styles_screen.css. In addition, the datagrid HTML templates feature allows you to deeply customize the appearance of your item results page.
If you want to customize the sentences used by DaDaBIK you can create your own custom language file, see Adding a new language translation and fix existing ones later
How to configure a drop-down lookup field
A lookup field is a field whose value is bound to another value in a source data table. For example let's say you have a table customers having, among the others, the fields address and city. Instead of setting the the field city as textbox, you want to provide the user a drop-down list which takes its values from a table cities having as fields ID and name. All you have to do is setting the following values (in the forms configurator), for the field city in the table customers:
- Field type: select_single
- Lookup table name: cities
- Lookup table primary key field: ID
- Lookup table linked fields: name
Configuring the field in this way, for the field customers.city you save in your database the ID of the city but you show to your users the name of the city. Also, you limit the options available to the cities you have in the table cities. The field customers.city needs to have the same database type the field cities.ID has, so if the ID is INTEGER, customers.city needs to be integer as well.
The select_single (drop-down list) is not the only DaDaBIK field compatible with the lookup approach: you can also use radio buttons, a list of checkboxes or a drop-down multiple select: all you have to do is selecting the right DaDaBIK field type: instead of select_single you need, respectively, select_single_radio, select_multiple_checkbox or select_multiple_menu.
It's worth mentioning that you are not limited to one linked field, you can add as many linked fields as you want. Let's say the table cities contains also the name of the region each city belongs to: cities (ID, name, region_name); you can add region_name as an additional linked field so that users will see in the drop-down menu not only the name of the city but also the name of the relative region.
For additional options related to lookup fields, including cascade fields, filtered lookup and the possibility to add a new item to a list on the fly, please refer to the in-line helps available for each parameter in forms configurator.
How to hide a field from a form
Hiding a field from a form or from the results grid is very simple: let's say you have a field salary in a table employees and you want to show the field only to some of your users, the users belonging to the group human resources. From the permissions menu of the admin section, choose employees as a table and, for each group, set the permissions: you probably want to set, for all groups except from admin and human resources, the permissions to NO for all the operations: RESULTS, EDIT, CREATE, DETAILS, QUICK SEARCH and SEARCH; the effect is that DaDaBIK will never show the field, the field will be excluded from the results grid, from the edit form, from the "create new" form, from the details page, from the quick search form (the boxes on the top of the results grid) and from the search form.
Please note that normally if you have a field which is auto-increment, you need to hide it form the CREATE form since the value needs to be assigned automatically from your DBMS (MySQL, PostrgreSQL, SQLite) and not entered by the user.
The permissions menu is used to set the presence of fields, as explained above, only if granular permissions are enabled (parameter $enable_granular_permissions in config.php), which is the default settings. If granular permissions are disabled, you can choose to hide a field directly from the forms configurator, in this case you set the presence of a field globally, for all the users.
How to manage uploaded file (images and other files) fields
DaDaBIK has two file field types, generic_file and image_file; both the field types generate in insert/edit forms an upload control that allows users to upload files. The difference between the generic_file and the image_file lies in how the file is displayed in the results grid and in the details page: for image_file fields, the actual image is displayed (using the img html tag), for generic_file fields, a link to the file is displayed.
To use the upload function you have to set the proper $upload_directory in config.php, the files uploaded, in fact, are not stored directly in the database but in the file system, the database stores just a reference to the file. From config.php you can also set the upload allowed file extensions and the size of the image thumbnails to show in results grid and details page.
How to create a Master/Details view (subforms)
A Master/Details view (also called subform) is an edit form (or a details page) that shows not only the details of a records but also one or more result grids displaying related records from other tables.
A typical example is the representation of an invoice (or an order):
Invoice n. 1 date 08/04/2017
Customer Bob Smith
Product Quantity Price
iPhone 7 1 700
USB Key 2 20
You probably represent the information using two tables:
(you probably want to store information related to products in a third
table but let's keep the example simple)
You can add as many details tables as you want to the same master.
How to create a pre-filtered results grid using VIEWS
Sometimes you want to show to your users a pre-filtered version of your data. Let's say for example you have a table products containing a field quantity_product, which stores, for each product, the quantity you have in your warehouse. If the table products is installed in DaDaBIK, it can be accessed from a menu item products and users can also execute search operations over it, for example, through the search form, they can ask to see only the products having a quantity value less than 10. If you realize that such query is quite common, you might want to offer to your users a direct access to the products having a quantity value less than 10, without forcing them to perform a search operation every time. You can do this using VIEWS.
A database view, informally, can be defined as a "virtual table" which is based on a real table; for example we can create a view products_low_stock based on the table products with this simple SQL statement:
The view products_low_stock can be installed in DaDaBIK as it was a normal table and therefore you can assign to it a menu item that allows users to directly access the products with low stock level in one click, without performing a search operation. Every time you access the view products_low_stock, your DBMS implicitly execute the query "SELECT * FROM products where quantity_product < 10" and provides you with the up-to-date results.
You can create a database view directly in DaDaBIK, admin section, pages menu:
For additional information about databaseviews, the Wikipedia entry is simple and quite informative: https://en.wikipedia.org/wiki/View_(SQL). A creative use of database views can help you in the process of creating very complex DaDaBIK applications.
How to create graphic reports
Starting from the results grid of any page based on tables/views you can create a graphic report; several chart types are available, including bar charts, line charts, pie charts and doughnut charts.
DaDaBIK provides two types of reports: simple reports and advanced SQL reports. You can create a simple report in a couple of clicks by selecting the field you want to put on your X-axis and the field you want to put on your Y-axis. Normally you want to aggregate data according to a field, show each group of data on your X-axis and and show some information related to each group on your Y-axis.
For example you might want to see the age composition of your customers: in this case you would choose to aggregate data by age and to show, for each group, the number of customers having that age (selecting the count option).
A slightly more complicated example: you have a table sales containing, among the other information, the date of the order and the amount. You want to see your revenues, month by month. In this case you need to choose month month - date_order for the X-axis and sum - amount for the Y-axis.
If you need more freedom, you can use the advanced SQL reports: you can specify your own SQL query, include a where clause, joining several tables and so on. The only constraints you have is: the query must be a SELECT statement where the first element you select will be used for the X-axis of the graph, the second element for the Y-axis.
Here is an example: let's say we have the following tables:
sales (id_sale, date_sale, customer_sale) - each sale can have several sale items:
sale_items (id_sale_item, id_sale (FK), id_product FK), quantity_sale_item) - each sale item refers a sale and a product
products (id_product, desc_product, price_product)
we want to show, for each month, the total revenues; here is an example of custom SQL report for MySQL:
If you have created a report and you want to easy access it later from the menu in one click, you can simply copy the URL you see in your browser when the report is displayed and create a custom page (having type = link) that points to this URL. Please note that, if the report has been generated after a search, the search filter is not saved together with the link. If you need to store a report based on a stable search filter, the best way is to create a VIEW and generate the report starting from that view.
A DaDaBIK hook is a feature that allows you to write some PHP code to be
called under certain circumstances.
DaDaBIK currently supports after insert, before update, after update and after delete hooks for each table installed in a DaDaBIK application, which means that for each table you can enrich the DaDaBIK workflow with your own code functions, that can be executed:
- after an insert operation (after insert hook)
- before an update operation (before update hook)
- after an update operation (after update hook)
- after a delete operation (after delete hook)
Let's say for example that, when a new order is inserted into your orders management application, you want to automatically update your stock: you can do it by using a hook; in particular if you store your orders in the orders table and your products information and quantity available in the products table, you can add an after insert hook on the table orders and write the code needed to update the records of the table products.
All your hooks functions must be written in the /include/custom_functions.php file
Let's say we want to send an email to a specific address when a new account is inserted in our system: this is a built-in DaDaBIK feature (see parameter $enable_insert_notice_email_sending in config.php) but let's say we don't to use the built-in feature and we want to implement it using our custom code. We could, as in the following example, define an after insert hook on the table accounts, setting the function that has to be executed (dadabik_send_notice_after_accounts_insert) and after we can write the code of the function, that retrieves the name of the account just inserted and send it via email to a specific address.
Please note that:
- you can use any name for hook functions, but the name MUST start with dadabik_
- if you need to execute operations on the database, you have to add the global $conn; code line (as in the above example)
- the after insert, update and delete hook functions receive as parameter the value of the primary key field of the record just inserted (if it is an autoincrement field), updated or deleted; the before update hook function receives as input the value of the PK of the field in update and (second parameter of the function) an associative array containing all the values the user filled in the update form (where the array element's key is the name of the field). Please note that on PostgreSQL the after insert hook doesn't fully work (it doesn't receive the value of the primary key of the record just inserted).
- the delete hook doesn't work after a "delete all" operation.
- You don't have to worry about transactions in your code: the after insert, update and delete hook functions are executed inside a transaction that starts before the insert, update and delete operations are executed and ends after the hook functions execution; the before update hook is also inside the same transaction which starts before its execution.
How to use calculated fields
A calculated field is a form field whose value is not directly entered by the user but is calculated according to a function.
For example you might have a table products containing the fields price, tax, total_price and you want the field total_price to be computed as price + tax. To get this results, you just need to fill - for the field total_price in forms configurator - the parameter "Calculated field function", setting the name of a custom function that will handle the calculation, for example dadabik_get_total_price. Then you need to write the function's code in /include/custom_functions.php. Here is an example of the simple dadabik_get_total_price:
The /include/custom_functions.php contains all the instructions to write these functions correctly.
How to share the same database between two or more DaDaBIK applications
Sometimes you want to build two (or more) different DaDaBIK applications which works on the same data (i.e. on the same database).
For example you want to build:
- A backend/data-entry application, from which you modify/enter data, accessible only to some people and
- A simpler, read-only, publicly available application that users can access without logging in.
- the database name (parameter $db_name) must be the same in all the config.php files
- the $prefix_internal_table parameter needs to be different and UNIQUE for each application
- use the $prefixes_to_exclude parameter to state, for each application, the prefixes (see previous rule) you have used in the other applications sharing the same database.
For example, if we have two applications sharing the same database, here is an example of config.php files
config.php application A
$db_name = 'my_database';
$prefix_internal_table = 'dadabik_1_';
config.php application B
$db_name = 'my_database';
$prefix_internal_table = 'dadabik_2_';
DaDaBIK provides a feature which allows to create in a DaDaBIK application custom pages running completely custom PHP code, with the only limitation of some variable naming rules. The feature needs to be enabled from config.php, setting $enable_custom_php_pages = 1.
DaDaBIK is released together with a Wordpress plug-in which allows to integrate a DaDaBIK application into a Wordpress site's page.
Furthermore, users authenticated through Wordpress can also be (optionally) automatically authenticated into DaDaBIK too, without logging-in again. The Wordpress authentication feature requires that the DaDABIK application is installed in a subdirectory of the Wordpress site and that the same users (same username) is available both in Wordpress and DaDaBIK.
Follow the instruction included in the wordpress_plugin folder to install and configure the plugin.[back to top]
Authentication is enabled by default, which means that, in order to use an application created with DaDaBIK, you have to login. You can disable authentication by setting $enable_authentication = 0 in /include/config.php; while this is not recommended, it can be useful if you want to use DaDaBIK to create a public Web site.
DaDaBIK is released with the following default users:
- username: root; password: letizia (this is a user belonging to the admin group)
- username: alfonso; password: letizia (this is a user belonging to the normal group)
Admin users can not only use a DaDaBIK application but also configure it through the admin area; furthermore, they can add new users/groups and edit/delete existing ones.[back to top]
Optionally, you can authenticate your users against an LDAP server. DaDaBIK has been tested with both Open LDAP and Microsoft Active Directory.
From /include/config.php you have to enable $ldap_authentication and specify all the parameters required for the connection. Users who authenticate using LDAP are then copied into the DaDaBIK users table and get assigned to a default (configurable) group. The aim of the copy is to allow the permissions setting, LDAP users authentication is always performed through the LDAP server.
Mixed authentication (some users authenticate against DaDaBIK, others against an LDAP server) is also possible: during the log-in procedure, a user can check/uncheck the LDAP checkbox in order to specify if he is going to authenticate through LDAP or not.[back to top]
If DaDaBIK is integrated into a Wordpress site, users authenticated through Wordpress can also be (optionally) automatically authenticated into DaDaBIK too, without doing the log-in again. See DaDaBIK Wordpress Integration for further details.[back to top]
For each table (each form and field), through the permissions manager, you can set which operations (Read, Create, Edit, Delete and Details) are allowed.
If you disable the read permission for a table, the related item won't be displayed in the menu of the application. Remember, however, that users can still read its records if the table is used as source of a select_single/select_multiple field or as items table in a master/details view.
If $enable_granular_permissions is set to 1 (this is the default settings) in /include/config.php you can set, through the permissions manager, which operations (Read, Create, Edit, Delete and Details) are allowed for each users group on each form and field.
For example you can configure your application to allow the group "Managers" to read and modify all the forms while the group "Employees" to read all the forms and modify just some of them, or just some fields of them.
As we said for the basic permissions, ff you disable the read permission for a table, the related item won't be displayed in the menu of the application. Remember, however, that users can still read its records if the table is used as source of a select_single/select_multiple field or as items table in a master/details view.
Integration with existing user and group lists
DaDaBIK uses by default the table dadabik_users and dadabik_groups to store users information, but you can also use existing user and group tables. This help the integration of DaDaBIK with existing applications, for example with a CMS.
To set DaDaBIK to use your own users and groups table, you have to configure the parameters starting with $users_table_ and $groups_table_ in /include/config.php; the integration is also possible if your users table doesn't use the same password encryption which DaDaBIK uses, in this case you have to customize the hashing functions as explained in /include/config.php
An owner permissions model is also available, it allows to set-up the application in a way such as users can:
- Delete only their own records
- Modify only their own records
- View only their own records
You can enable this feature from the permissions manager; to enable it, authentication must be enabled and each table you want to protect must have a field whose DaDaBIK field type is set to ID_user. When a field is set to ID_user, the username of the current user will be automatically inserted by DaDaBIK into this field when you insert a new record. If you want to base the ownership on the group instead of the user, change $use_id_group_for_ownership in /include/config.php
Please note that you can enable the owner permissions also for VIEWS, but also for VIEWS (as for TABLES) you need a working ID_user field, VIEWS don't automatically inherit form settings from the underlying tables. In some cases, however, you cannot directly insert records into a view (the DBMS won't allow you to do it, to read some more details related to MySQL see https://dev.mysql.com/doc/refman/5.7/en/view-updatability.html) so the correct ID_user value must come from the underlying tables.[back to top]
Some of the language translations are incomplete. If you open your language file (e.g. include/languages/spanish.php ) you can find the sentences not translated looking at the // to change comments at the end of each file row. You can complete the translation if you want. You are more than welcome to contribute to the localization sending back to info at dadabik dot org your improved translation.
A better way to modify a translation if you don't like the original one, however, is to use, instead of the original file (e.g. english.php) the corresponding custom file (english_custom.php); this is very useful to avoid loosing your custom translations during the upgrade of DaDaBIK. It is also possible to differentiate your custom translations according to the table the user is using. Open the file include/languages/english_custom.php to read the simple instructions you need to override an original translation.
Adding a new language translation is also pretty straightforward. For example, imagine you want to add Hindi: you just need to create a copy of the file /include/languages/english.php, rename it as hindi.php, and edit all the sentences of the file (for each row, the quoted part after the arrow). You can then add the language to the list of available choices adding 'hindi' to the parameter $languages_ar is /include/config.php.[back to top]
Here is some security-related information which you must know:
- If your DaDaBIK instance is public and you have disabled authentication (by default IS enabled), please consider disabling the export to CSV feature from /include/config.php because robots, accessing the CSV export link, could consume an inordinate amount of processor time.
- You should protect the upload directory from public access, otherwise anyone who knows the URL of a file you have uploaded via DaDaBIK can access the file itself, even without logging-in. By default, the /uploads folder contains an .htaccess file which should prevent public access on Apache, please test it because it might not work in your environment; if you change the default upload directory or use a different Web server than Apache you should provide the needed security by yourself.
- After having installed and configured a DaDaBIK application, it's a good practice to remove the files install.php and upgrade.php, since they could be used by malicious users in order to change or even re-install your DaDaBIK installation.
- The files admin.php, datagrid_configurator.php, db_synchro.php, internal_table_manager.php, permissions_manager.php and tables_inclusion.php can also be used to modify your application. If authentication is enabled, the access to the files will be protected, otherwise you should remove those files. For additional security, you can however remove the files even if authentication is enabled.
Please read the FAQ document.[back to top]
- UTF-8 related:
- DaDaBIK supports UTF-8; however, malformed UTF-8 characters can lead to unexpected results such as content corruption. The use of the HTML content type or of the rich text editor, in combination with UTF-8 content, is another factor that could lead, theoretically, to unexpected results.
- Security/data-integrity related:
- Searching values containing % or _ using the "contains", "starts with" or "ends with" conditions could lead to wrong search results.
- Table and field names related:
- Insert/search/update and some other operations fail if one or more field or table names contain blank spaces or dots (e.g. "my field" or "my.field" are not allowed, use "my_field" instead).
- Quote characters and characters which need to be esacped such as ' ` " \, can lead to problems if used in table and field names.
- Using field names containing the value set for $alias_prefix, $null_checkbox_prefix, $select_type_select_suffix, $year_field_suffix, $month_field_suffix, $day_field_suffix, $hours_field_suffix, $minutes_field_suffix, $seconds_field_suffix could lead to unexpected results; you can change the value of the above variables editing /include/config.php
- User interface related:
- Some language translations are not completed. If you open your language file (e.g. include/languages/spanish.php ) you can find the sentences not translated looking at the // to change comments at the end of each file row. You can complete the translation if you want.
- The rich editor interface (TinyMCE) is displayed in english only.
- PosgreSQL related:
- DaDaBIK needs table names in lower case to work on PostgreSQL.
- The tables you want to use in your DaDaBIK application needs to be in the "Public" schema.
- The insert e-mail notice doesn't work on PostgreSQL.
- Insert/update don't work correctly on PostgreSQL if the user choose "Other...." from a select_single field menu and the field has some linked fields.
- The after-insert hook doesn't fully work (it doesn't receive the value of the primary key of the record just inserted).
- MySQL related:
- DaDaBIK doesn't support the BIT MySQL field type.
- Admin section related:
- The field renaming feature of the administration page doesn't work as expected if the renamed field is used in one of the following properties: "Primary key field", "Linked fields", "Order by", "Where clause" in the forms configurator related to any of the tables. In particular, after the renaming, you will get " Error: during query execution" messages from the DaDaBIK front end; you should edit the above properties by hand, renaming the field in the forms configurator.
- The "refresh installation" admin operation doesn't work correctly and could lead to a forms configurator settings loss if the installation is the result of an upgrade from a DaDaBIK version < 4.1 rc2; the "refresh installation" bug is considered fixed only for tables installed (DaDaBIK installation from scratch or single table installation from the admin interface) using a DaDaBIK version >= 4.1 rc2.
- The "previous" and "next" buttons don't work correctly after this sequence of operations: - perform a search based on a field A - change the value the field A for a record of the resultset
- Primary keys composed by multiple columns are not handled.
- Nested Master/Details views (a master/details view on a table which is already in a master/details view as details table) don't work correctly.
- Upload and deletion of multiple files during the same insert/update/delete operation are not considered as a unique atomic operation: e.g. if you are uploading multiple files from the same form and one of the uploads fails, other files already uploaded will result available in the file system.
- The "check for duplicated" feature doesn't work with file field types: DaDaBIK doesn't warn about similarity when two files have a similar name; furthermore, the "check for duplicated" feature causes uploads to fail during insert, in particular the files are not uploaded if some possible duplicated records are found and the user decides to insert it anyway. The "check for duplicated" feature also doesn't work with date, date_time, insert_date and update_date field typed and with all fields which are hidden in the insert form.
- HTML content is not set correctly as "Default value" (form configurator).
- When a new option of a select_single field with linked fields is inserted through the "other..." option, the current user is not inserted in the ID_user field of the linked table. This means that the new record in the linked table won't get an owner and the owner permissions won't work as expected.
- If, while editing a record, you change the value of the primary key, DaDaBIK is not able to show you the updated record after saving.
- If an insert/edit form needs to be re-displayed because an error occurred (e.g. a missing required field), FILE fields (only file fields) don't preserve the values set by the user before submitting the form
- If an image_file or generic_file field is used as a linked field for a lookup field, the file is not showed if the user doesn't have read permissions on the corresponding linked table.
- Unexpected behaviors (not really DaDaBIK bugs but behaviors which the average user doesn't expect)
- DaDaBIK relies on the $timezone parameter for date functions (e.g. to produce the current date), which can be different from the client's (user) one.
- The value actually inserted in the database during an insert/update, if the value typed in the form is not part of the domain specified during table creation (e.g. integer, varchar,...), depends on the DBMS settings and on the domain itself. For example if an integer field is left blank during insert/update (not NULL, blank), MySQL could insert 0 as value, because an empty string is not part of the integer domain and very often the default value for integers is set to 0.
- Formatting tags automatically inserted in a field through the HTML editor are not filtered during search so if you search "hey good" and you have "<b>hey</b> good morning" in your field you won't find it.
- If you set a master/details view between table A (master) and table B (details) and you perform a search on B and then access (in edit or details mode) a record of the table A, you will then lose the search filter you had in B.
- The Wordpress and DaDaBIK session expirations are not synchronized: if your session expires in Wordpress it doesn't mean it automatically expires in DaDaBIK. Use the logout button in Wordpress to be sure to disconnect to both Wordpress and DaDaBIK
- If you have enabled the Wordpress authentication, you should login/logout through Wordpress without using DaDaBIK login/lougout; mixing Wordpress and DaDaBIK login/logout can lead to unexpected behaviours.
- If an error occurs during installation or upgrade, the installation of DaDaBIK can ends up in a inconsistent state due to implicit commit policies of the DBMS.
- Old versions of Microsoft Excel for Mac can't correctly represent UTF-8 characters for CSV files produced by DaDaBIK
