Help needed with my first plugin - a space issue

Hey

I need to turn every word in a string into an include. So despite my lack of php skills I thought I’d try to build my very first plug-in to handle things, but I’ve run into some issues…

First, the idea is to take a custom field and turn every word in that field into an embed, or in my case, an include.

{exp:weblog:entries weblog="main"}

 {exp:explodeinclude url="http://www.example.com/index.php/modules/"}
  {modules}
 {/exp:explodeinclude}

{/exp:weblog:entries}

Should be simple, right? Well, below is what I’ve got so far. Please bare in mind that I don’t actually know php… 😛

class Explodeinclude
{

var $return_data = "";

  function Explodeinclude()
  {
    global $TMPL;
    
    $url = $TMPL->fetch_param('url');
    $url = str_replace( "/","/",$url); 
    
    // Input string
    $string = $TMPL->tagdata;

    // Create an array from input
    $modules = explode(',',strtolower($string));
    
    // Add all found words to the new array
    foreach($modules as $module){
        include($url.$module);
       }


    $this->return_data = $TMPL->tagdata;
  }

}

The issues I’ve got are:

1. Even if placed under a heading and other content, the code rendered by the plugin is displayed at the very top of the page.

2. A space is placed in front of the $module segment of the url.

3. It would be great if I could just specify the template group and template instead of the full url. Although I’m not sure if it’ll work as I may have to use the server path anyway…

Any help would be much appreciated!
