Usage:



My plugins: Never need patches or special requirements, no hassle... Just paste it and use it.. and they all use the Zend framework syntax guidelines and php5 (that's how we roll)


Non-associate array:
Quote:

{array vars="array('hours','days','months')" assign="foo"}


{foreach from=$foo item=v}
--<b>{$v}</b><br />
{/foreach}

output:


--hours
--days
--months




Associate array:


Quote:

{array vars="array('hours' =>'Hours','days' =>'Days','months'=>'Months')" assign="foo"}

{foreach from=$foo key=k item=v}
--<b>{$k}</b> - <b>{$v}</b><br />
{/foreach}

output:

--hours - Hours
--days - Days
--months - Months






Hello,

I this is a new plugin which allows you to create an array inside smarty.

Notice that to create an array you would need to be consistent in weather your arrays is associate or not. It can create either one of the two, but not both at the same time mixed together (at the moment).
Any how, by this I mean..
Associate:
Code:
 array('key 1' => 'value 1','key 2' =>'value 2');

Or
Non- Associate:
Code:
 array('value 1' , 'value 2');






Here is the plugin

Code:
plugins/function.array.php




Code:

<?php

 **/

function smarty_function_array($params, &$smarty)
{
   $array = (isset($params['vars'])?$params['vars']:null);
   if(!$array) {
      return;
   }
   $new_array = array();
   if(strpos($array,"=>") !==false) {
      preg_match_all("/(['|\"]*([a-zA-Z0-9_\s\t\n]+)['|\"]*\s*\=\>\s*['|\"]*([a-zA-Z0-9_\s\t\n]+)['|\"]*\s*)+/",$array,$arr,PREG_SET_ORDER);   
      foreach($arr as $k =>$v) {
         $new_array[$v[2]] =$v[3];
      }
   } else {
      preg_match_all("/(['|\"]*([a-zA-Z0-9_\s\t\n]+)['|\"]*\s*)+/",$array,$arr,  PREG_SET_ORDER);   
      unset($arr[0]);
      foreach($arr as $k =>$v) {
         $new_array[] =$v[2];
      }
   }
   if(count(array_keys($params))==2 && isset($params['assign'])) {
      $smarty->_tpl_vars[$params['assign']] = $new_array;
   }
}



Code:
should work with php4, but I recommend php5


Feedback is welcome Very Happy

There is also the {set } compiler plugin in the wiki.

Just so you know, your code is broken. A simple "/" in the value will mess up the array parsing.
Why don't you use "eval()" ? Since the value is in the code there is no risk of malicious code injection.

Code:
   $array = (isset($params['vars'])?$params['vars']:null);
   if(!$array) {
      return;
   }

   eval ('$new_array = '.$array.';');

   if(count(array_keys($params))==2 && isset($params['assign'])) {
      $smarty->_tpl_vars[$params['assign']] = $new_array;
   }
