Plugin Hooks
|
|
============
|
|
|
|
Application Hooks
|
|
-----------------
|
|
|
|
Hooks can extend, replace, filter data or change the default behavior. Each hook is identified with a unique name, example: `controller:calendar:user:events`
|
|
|
|
### Listen on hook events
|
|
|
|
In your `initialize()` method you need to call the method `on()` of the class `Kanboard\Core\Plugin\Hook`:
|
|
|
|
```php
|
|
$this->hook->on('hook_name', $callable);
|
|
```
|
|
|
|
The first argument is the name of the hook and the second is a PHP callable.
|
|
|
|
### Hooks executed only one time
|
|
|
|
Some hooks can have only one listener:
|
|
|
|
#### model:subtask-time-tracking:calculate:time-spent
|
|
|
|
- Override time spent calculation when subtask timer is stopped
|
|
- Arguments:
|
|
- `$user_id` (integer)
|
|
- `$start` (DateTime)
|
|
- `$end` (DateTime)
|
|
|
|
#### model:subtask-time-tracking:calendar:events
|
|
|
|
- Override subtask time tracking events to display the calendar
|
|
- Arguments:
|
|
- `$user_id` (integer)
|
|
- `$events` (array)
|
|
- `$start` (string, ISO-8601 format)
|
|
- `$end` (string, ISO-8601 format)
|
|
|
|
### Merge hooks
|
|
|
|
"Merge hooks" act in the same way as the function `array_merge`. The hook callback must return an array. This array will be merged with the default one.
|
|
|
|
Example to add events in the user calendar:
|
|
|
|
```php
|
|
class Plugin extends Base
|
|
{
|
|
public function initialize()
|
|
{
|
|
$container = $this->container;
|
|
|
|
$this->hook->on('controller:calendar:user:events', function($user_id, $start, $end) use ($container) {
|
|
$model = new SubtaskForecast($container);
|
|
return $model->getCalendarEvents($user_id, $end); // Return new events
|
|
});
|
|
}
|
|
}
|
|
```
|
|
|
|
List of merge hooks:
|
|
|
|
#### controller:calendar:project:events
|
|
|
|
- Add more events to the project calendar
|
|
- Arguments:
|
|
- `$project_id` (integer)
|
|
- `$start` Calendar start date (string, ISO-8601 format)
|
|
- `$end` Calendar` end date (string, ISO-8601 format)
|
|
|
|
#### controller:calendar:user:events
|
|
|
|
- Add more events to the user calendar
|
|
- Arguments:
|
|
- `$user_id` (integer)
|
|
- `$start` Calendar start date (string, ISO-8601 format)
|
|
- `$end` Calendar end date (string, ISO-8601 format)
|
|
|
|
Asset Hooks
|
|
-----------
|
|
|
|
Asset hooks can be used to add easily a new stylesheet or a new javascript file in the layout. You can use this feature to create a theme and override all Kanboard default styles.
|
|
|
|
Example to add a new stylesheet:
|
|
|
|
```php
|
|
<?php
|
|
|
|
namespace Kanboard\Plugin\Css;
|
|
|
|
use Kanboard\Core\Plugin\Base;
|
|
|
|
class Plugin extends Base
|
|
{
|
|
public function initialize()
|
|
{
|
|
$this->hook->on('template:layout:css', 'plugins/Css/skin.css');
|
|
}
|
|
}
|
|
```
|
|
|
|
List of asset Hooks:
|
|
|
|
- `template:layout:css`
|
|
- `template:layout:js`
|
|
|
|
Template Hooks
|
|
--------------
|
|
|
|
Template hooks allow to add new content in existing templates.
|
|
|
|
Example to add new content in the dashboard sidebar:
|
|
|
|
```php
|
|
$this->template->hook->attach('template:dashboard:sidebar', 'myplugin:dashboard/sidebar');
|
|
```
|
|
|
|
This call is usually defined in the `initialize()` method.
|
|
The first argument is name of the hook and the second argument is the template name.
|
|
|
|
Template names prefixed with the plugin name and colon indicate the location of the template.
|
|
|
|
Example with `myplugin:dashboard/sidebar`:
|
|
|
|
- `myplugin` is the name of your plugin (lowercase)
|
|
- `dashboard/sidebar` is the template name
|
|
- On the filesystem, the plugin will be located here: `plugins\Myplugin\Template\dashboard\sidebar.php`
|
|
- Templates are written in pure PHP (don't forget to escape data)
|
|
|
|
Template name without prefix are core templates.
|
|
|
|
List of template hooks:
|
|
|
|
- `template:auth:login-form:before`
|
|
- `template:auth:login-form:after`
|
|
- `template:dashboard:sidebar`
|
|
- `template:config:sidebar`
|
|
- `template:config:integrations`
|
|
- `template:project:integrations`
|
|
- `template:user:integrations`
|
|
- `template:export:sidebar`
|
|
- `template:layout:head`
|
|
- `template:layout:top`
|
|
- `template:layout:bottom`
|
|
- `template:project:dropdown`: "Actions" menu on left in different project views
|
|
- `template:project:header:before`
|
|
- `template:project:header:after`
|
|
- `template:project-user:sidebar`
|
|
- `template:task:sidebar:information`
|
|
- `template:task:sidebar:actions`
|
|
- `template:user:sidebar:information`
|
|
- `template:user:sidebar:actions`
|
|
|
|
Other template hooks can be added if necessary, just ask on the issue tracker.
