This is the function which this asset calls.
I have copied this function from Mysource



cms/page-templates/custom_form asset folder



to learn how asset is made




    function redirectToFormContents(&$asset, &$o, $prefix)
    	{
    		// get the bodycopy attached to us
    		$form = $asset->getForm();
    
    		if (is_null($form)) {
    			trigger_localised_error('CMS0022', E_USER_ERROR, $asset->name, $asset->id, 'Contents');
    			return FALSE;
    		}
    
    		// redirect to the bodycopy's edit contents screen
    		$o->setRedirect($form->getBackendHref('contents'));
    
    		// fudge the navigation history a little so when they click on the link to ger back to the
    		// page it doesnt take them to the edit contents screen and then redirect them again
    		$_SESSION['sq_nav_history'][(count($_SESSION['sq_nav_history']) - 1)]['screen'] = 'details';
    
    		return FALSE;
    
    	}//end
