[TYPO3-project-formidable] T3CON06 Demo, delete the image.

[Asbjørn Morell]

Thanks Jerome.
That's was indeed the problem :) May I kindle ask you another question? The 
variable $iUid is empty when I click the lnk_delete_image link. Do you know 
how I can make it available ? (step2.xml)

Best regards.

  <renderlet:LINK name="lnk_delete_image" activelistable="true">
   <label>Delete image</label>
   <onclick
    runat="server"
    params="uid"
    confirm="Are you sure you want to delete this image ?"
    when="start"
   >
    <userobj>
     <php><![CDATA[

      $aParams = func_get_args();
      $iUid = $aParams[1]["uid"];

      $updateFields = array('image' => '');

      $GLOBALS["TYPO3_DB"]->exec_UPDATEquery(
       "tx_ameost3con06_car",
       "uid='" . $iUid . "'",
       $updateFields
      );

      debug($this->_oParent);
