Creating a new task

Creating the task class

This is the heart of a task. It is the code that actually does what the task is supposed to do. A task is represented by a PHP class that implements the interface \TYPO3\CMS\Taskcenter\TaskInterface:

namespace Foo\Bar\Task;
class DoSomething implements \TYPO3\CMS\Taskcenter\TaskInterface {
  public function getTask() {
            ...
  }
  public function getOverview() {
            ...
 }
}

The 2 mentioned method must be implemented!

getTask()

The function getTask() is expected to perform the task logic and returns the content of the task.

getOverview()

The function getOverview() creates an optional menu of items or description which is rendered in the menu of tasks.

Autoloading

The Taskcenter expects all task classes to be available with the TYPO3 autoloader. They thus must be declared in the ext_autoload.php file of the extension that provides these classes. Again the ext_autoload.php file of sys_action can be used as an example.

Declaring the task class

As a last step, the task class must be declared so the Taskcenter knows of its existence. The declaration must be placed in the ext_tables.php file of the extension that provides the task. Let’s look at the declaration of sys_action as an example:

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['taskcenter']['sys_action']['tx_sysaction_task'] = array(
        'title' => 'LLL:EXT:sys_action/Resources/Private/Language/locallang_tca.xlf:sys_action',
        'description' => 'LLL:EXT:sys_action/Resources/Private/Language/locallang_csh_sysaction.xlf:.description',
        'icon' => 'EXT:sys_action/Resources/Public/Images/x-sys_action.png'
);

The registration is made in the array $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['taskcenter']. A key is then used that corresponds to the task class (in bold above). Then come 3 parameters:

• title : the name of the task. May use localized labels.
• description : a text describing the task. It is displayed in the information screen of the BE module. May use localized labels.
• icon : Path to an icon for the task.
