Hi, use this modifier to be abel to write Smarty-tags inside a text that you get from a database, Hope this will work for you!


Code:
/*
 * Smarty plugin
 * -------------------------------------------------------------
 * File:   modifier.do_eval.php
 * Type:   modifier
 * Name:   do_eval
 * ver       0.1.0
 * date:   2004-03-16
 * Purpose: run eval, enable Smartytags inside txt filelds from db
 * -------------------------------------------------------------
 */

/* {$data|do_eval} */

function smarty_modifier_do_eval($doc) {
   global $smarty;
   $smarty->assign('doc_to_eval', $doc);
   $evald = $smarty->fetch('eval.tpl');
    return $evald;
}



eval.tpl
Code:
{eval var=$doc_to_eval}

Do you have any idea how to do it without globals?
Code:
global $smarty;

I wondering that $smarty is not passed to modifier plugins... Crying or Very sad

extend class smarty and register the modifier as an object's method.

or register the modifier as a static method of any class. inside this static method $this will become a reference to (the calling) smarty-object then.

Right. I always register plugins within Smarty extention class. But I always used &$smarty parameter before in order to make profit of the Smarty functionality. Obviously in this case &$smarty is the pointer to the same instance as $this. Fine!
