Hi all

I am developing a plugin to display links to others categories in a menu.
I have a custom field for each category with no formatting, where I enter the categories names of categories I want to link to separated by a comma.

In my template I explode the string to get the different names and pass the parameter to the plugin:

<?php  
              // check for related articles //
              $Rel_Art ="{embed:Rel_Art}"; 
              if($Rel_Art !="") { 
                   $rel_art_array = explode (',', $Rel_Art);
                   for ($i = 0; $i <count($rel_art_array); $i++){
                     $relation = $rel_art_array[$i];                     
                  ?>
                       {exp:cat_relations:get_relations relation='<?php echo $relation ?>' url='{site}index.php/'}                    
                   <?php 
                                 } 
            } ?>

Then my function in the pi file queries the database to find a category that matches this parameter. But I don’t get any results. However if I hardcode the parameter value, it works, so the query is right.

The problem is in this relation parameter, but when echoing it also looks fine.

Is there anything I am missing on my php or any EE peculiarity here?

Thank you
