Hello,

I am doing some tests with a little output filter plugin.
I have an error I don't understand :

[ERROR]
Fatal error: Smarty error: [in test_smarty.tpl line 3]: syntax error: unrecognized tag 'rewrite_url' (Smarty_Compiler.class.php, line 583) in f:\www\tests\class\smarty\libs\Smarty.class.php on line 1095
[/ERROR]

My template test_smarty.tpl :

[TEMPLATE]

<html>
{assign var="resultat" value='index.php?cat=21'}
{rewrite_url resultat}
</html>

[/TEMPLATE]

My plugin file is called "outputfilter.rewrite_url.php" and is placed in the plugins directory of my application.

[PLUGIN]

<?php
function smarty_outputfilter_rewrite_url($params, &$Smarty)
{
$pattern = array('/index\.php\?cat=([0-9]+)/');

$replace = array('index-cat-$1.html');
echo "start of rewrite_url"; // for tests
return preg_replace($pattern, $replace, $params['string']);
$smarty->assign('resultat',$params['string']);
echo "end of rewrite_url"; // for tests
}
?>

[/PLUGIN]

The plugin is loaded in my Smarty class [

[CLASS]
<?php
//define('TEST_ROOT_PATH', '/www/iasext/tests');
define('TEST_ROOT_PATH', 'f:/www/tests');
define('SMARTY_DIR', TEST_ROOT_PATH.'/class/smarty/libs/');

require_once SMARTY_DIR.'Smarty.class.php';

// charge la librairie Smarty

class Smarty_test extends Smarty {
function Smarty_test() {

// Constructeur de la classe. Appelé automatiquement
// à l’instanciation de la classe.
$this->Smarty();
$this->template_dir = SMARTY_DIR.'template/templates/';
$this->compile_dir = SMARTY_DIR.'template/templates_c/';
$this->config_dir = SMARTY_DIR.'template/configs/';
$this->cache_dir = SMARTY_DIR.'template/cache/';
$this->compile_check = false;
$this->debugging = false;
$this->caching = false;
$this->load_filter('output', 'rewrite_url');
$this->assign('app_name','test');
}
}
?>
[/CLASS]

I hope my presentation is consize and comprehensible
Someone for an idea please ?
Best regards

Tonysmarty

Maybe it is also necessary to call register_postfilter() method...

I think a modfier is the better way to solve your problem.
Code:

{assign var="resultat" value='index.php?cat=21'}
{$resultat|rewrite_url}



Code:

<?php
/*
 * Smarty plugin
 * -------------------------------------------------------------
 * File:     modifier.rewrite_url.php
 * Type:     modifier
 * Name:     rewrite_url
 * -------------------------------------------------------------
 */
function smarty_modifier_rewrite_url($url)
{
    //do your rewrite
    return $url;
}
?>

The only thing with using a modifier is you would have to go back and edit all your templates...

A filter does a global search/replace type thing without the need to edit your templates.

There is a help from me, if you want rewrite urls do this:

function.to_url.php:

Code:

<?php

function smarty_function_to_url($params, &$smarty)
{
   global $mod_rewrite_urls,$links;

   !is_array($params) ? $params=array():"";
   if ($params['re']){
      $remove_empty = true;
      unset($params['re']);
   }

   if ($mod_rewrite_urls){

      foreach ($params as $key=>$value){

               if ($key == "a"){
                 $u[] = $links[$value]?$links[$value]:$value;
                 $x = $value;
               }elseif( ($value  or (!$value and !$remove_empty)) and $key !="query"){
                 $x = $value;
                 $value =="none" ? $value="":"";
                 $u[] = $key.$value;
               }
      }
      if ($u) $url = join ("/",$u).($x !="none" ?".html":"");

   }else{

      foreach ($params as $key=>$value){

               if ($key=="a"){
                 $u[] = "a=". ($links[$value]?$links[$value]:$value);
               }elseif ($key !="query"){
                 $u[] = $key."=". $value;
               }
      }

      if ($u) $ux ="?".join ("&amp;",$u);
      $url = "index.php".$ux;
   }

   if ($mod_rewrite_urls and $params['query']){
        $url .= "?".$params['query'];
   }elseif($params['query']){

        $url .= (strstr($url,"?") ? "&amp;":"?").$params['query'];
   }

     return HOST_PATH.$url;
}

?>


Also an conbert_to_url function:

Code:

function convert_to_url($url,$misc=true,$addvars=""){

global $mod_rewrite_urls,$links;

   if ($mod_rewrite_urls){

      $url_parts =  parse_url($url);
      parse_str($url_parts['query'],$query);

/*      $url = $links[$query['a']]."/";
      unset ($query['a']);
      $url .= join("/",$query);*/

      foreach ($query as $key=>$value){

               if ($key == "a"){
                  $u[] = $links[$value]?$links[$value]:$value;

               }else{
                 $u[] = $key.$value;
               }
      }
      if ($u) $url = join ("/",$u).($misc?"/":"");
   }

   if ($mod_rewrite_urls and $addvars){
        $url .= "?".$addvars;
   }elseif($query and $addvars){
        $url .= (strstr($url,"?") ? "&amp;":"?").$addvars;
   }

    return htmlentities(HOST_PATH.$url);
}


First Example:
<a href="{to_url foo="foo" bar="bar"}">Link Here</a>
Second Example:

Code:

$page_href = convert_to_url("index.php?a=".$links['topic']."&t=".$topic['tid'],false); // ."&page="
