Description

If i implemment the following hook compatible with 4.x i get a fatal PHP-Error. Im running TYPO3 6.0 on php 5.3.6.

Error:

Fatal error: Declaration of tx_t3_default_resources_txCmsLayoutDrawItemHook::preProcess() must be compatible with that of TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface::preProcess() in /Users/martin/Public/localhost/t3_default/www-data/typo3conf/ext/t3_default_resources/Classes/Hooks/txCmsLayoutDrawItemHook.php on line 4

Hook:

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']

Old implementation that fails in 6.0:

class tx_t3_default_resources_txCmsLayoutDrawItemHook implements tx_cms_layout_tt_content_drawItemHook {
  public function preProcess(tx_cms_layout &$parentObject, &$drawItem, &$headerContent, &$itemContent, array &$row){
  }
}

New namespaced implementation that works but is incompatible with 4.x:

class tx_t3_default_resources_txCmsLayoutDrawItemHook implements \TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface {
  public function preProcess(tx_cms_layout &$parentObject, &$drawItem, &$headerContent, &$itemContent, array &$row){
  }
}

So currently it is not possible to implement this hook for 4.x and 6.0.

Regards Martin

Sorry the correct implementation with the namespaced classes is here:

class tx_t3_default_resources_txCmsLayoutDrawItemHook implements \TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface {
  public function preProcess(\TYPO3\CMS\Backend\View\PageLayoutView &$parentObject, &$drawItem, &$headerContent, &$itemContent, array &$row){
  }
}

I fear you have to update your PHP version.

Minimum for TYPO3 CMS 6.0 is PHP 5.3.7

Could you try to skip the class path in the hook definition and put this information in the ext_autoload.php of the extension?

So instead writing "EXT:ext_xyz/Classes…/YourHookClass.php:YourHookClass" just "YourHookClass". By using the autoloader for the class the compatibility layer can kick in and rewrite the typehints.

This is probably the same issue as in #40653, the solution is also presented there in my comment 11. Please confirm so that we can close this. I would then add an additional note on that original issue that other hooks might also be affected that work in a similar way.
