Smarty

Heelo,

I'm trying to use prefilter what I've never done before.


I have in smarty_dir/extraplugins/utils
the file prefilter.literalScriptAndStyle.php


This file is :


<?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File: prefilter.literalScriptAndStyle.php
* Type: prefilter
* Name: literalScriptAndStyle
* Purpose: Add {literal} to style and script tags.
* -------------------------------------------------------------
*/
function smarty_prefilter_literalScriptAndStyle(&$tpl_source, &$smarty)
{
// <javascript>
$pattern[] = '~<script\b(?![^>]*smarty)(.*)</script>~iU';
$replace[] = '<!--{literal}--><script$1>$2</script><!--{/literal}-->';


// <style>
$pattern[] = '~<style\b(?![^>]*smarty)(.*)</style>~iU';
$replace[] = '<!--{literal}--><style$1>$2</style><!--{/literal}-->';



return preg_replace($pattern, $replace, $tpl_source);
} // function
?>


I have a smarty.config.php file containing


// VARIOUS DEFINE....
Class My_Smarty extends Smarty
{
/**
* Constructor
**/
function My_Smarty ()
{
$this->use_sub_dirs = true;
$this->compile_check = true;
$this->debugging = false;
$this->debugging_ctrl = 'NONE';
$this->caching = false;
$this->template_dir = _APPLIPATH.'/templates';
$this->compile_dir = _SMARTYPATH.'/templates_c';
$this->config_dir = _SMARTYPATH.'/configs';
$this->cache_dir = _SMARTYPATH.'/cache';
$this->debug_tpl = _SMARTYPATH.'/debug.tpl';
$this->cache_lifetime = 3600;
$this->plugins_dir = Array('plugins',
'extraplugins/rss',
'extraplugins/utils');
$this->register_prefilter('literalScriptAndStyle');
}
}


Result :


Fatal error: Smarty error: [plugin] prefilter 'smarty_prefilter_literalScriptAndStyle' is not implemented in f:\easyphp\www\PATH_TO_SMARTYDIR\Smarty.class.php on line 1895


I tried to place


$smarty->register_prefilter('literalScriptAndStyle');


in my index.php file
<?php
session_start();
include 'include/smarty.config.php';
$smarty = new My_Smarty;
$smarty->register_prefilter('smarty_prefilter_literalScriptAndStyle');
.....


With the same result

The register_prefilter() function is to register an existing function as a prefilter, whereas load_filter() will instruct a filter to be loaded from the plugin directory and registered. So in your case:

$smarty->load_filter('pre','literalScriptAndStyle');

should work.
