I'm trying to extend the 'page' properties form by extending the page db table and TCA array from within an extension. This works, except that my custom function won't be called. If I replace my own itemsProcFunc line with a TYPO3 core function itemsProcFunc line it works, but with my own function it never works (I just get an empty result/selectlist, even when I simply return a dummy array: "return array('title','1');"....
Here's my code in my extension's ext_tables.php:
<?php
$TCA['pages']['columns'] += array(
'targetelement' => array(
'exclude' => 0,
'label' => 'Target element (first select a target page!)',
'config' => array (
'type' => 'select',
'items' => Array (
Array('',0),
),
'size' => 1,
'minitems' => 1,
'maxitems' => 1,
//'itemsProcFunc' => 'TYPO3\CMS\Backend\View\BackendLayoutView->addBackendLayoutItems',
'itemsProcFunc' => 'Vendor\Myextension\Controller\Hooks\CustomTargetElementSelector->getContentElements',
),
)
);
t3lib_extMgm::addToAllTCAtypes('pages', 'targetelement,', '2', 'after:nav_title');
t3lib_extMgm::addToAllTCAtypes('pages', 'targetelement', '1,5,4,199,254', 'after:title');
P.s. I replace Vendor\Myextension for my own namespace of course.
I don't know where to put my function file exactly, I assume in extension\Classes\Controllers\Hooks\CustomTargetElementSelector.php.
My ultimate goal is to display a list of content elements of the selected shortcut page UID..
P.s.2 my CustomTargetElementSelect.php file looks like this (contents just return a single item, dummy list result:
<?php
namespace Vendor\Myextension\Controller;
class CustomTargetElementsSelector extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController {
public function getContentElements(array &$params,$pObj){
return array('title','uid');
}
}
First of all, an itemsProcFunc should be a simple class; I never tested if an Extbase controller context is available in an itemsProcFunc.
Your hook should (this is just a recommendation) reside in
yourext/Classes/Hook/CustomTargetElementSelector.php
Namespace:
namespace Vendor\Yourext\Hook;
class CustomTargetElementSelector {
[method inside]
}
After flushing the system cache, if the hook still has no function, set a die() statement within the function to find out if the function is called at all. Currently it cannot work because the location of your class (Controllers/Hooks) and the namespace (Controller) don't fit.
For the sake of full 6.2/7 compatibility, replace
t3lib_extMgm::
by
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::
