require_once("$IP/extensions/ckeditor/ckeditor.php");
$wgHooks['EditPage::showEditForm:initial'][] = 'showEditForm'; 
function showEditForm($form)
{ 
    global $wgOut; 
    $wgOut->addScriptFile( '/extensions/ckeditor/ckeditor.js' ); 
    $script = "<script type="text/javascript"> window.onload = function() 
   { 
    CKEDITOR.replace( 'wpTextbox1' ); }; 
    if ( window.removeEventListener ) window.removeEventListener( 'load', mwSetupToolbar, false ) ; 
     else if ( window.detachEvent ) window.detachEvent( 'onload', mwSetupToolbar ) ; </script>";
