Hoping the developers read this.

So i have my own display and fetch functions that override smarts, they both simply add cache and compile id's to the call.

However one of my pages stops right at line 182 of smarty_internal_templatebase.php

the line is ob_start();

it doesn't throw and expection, toss any php error or anything. Just seems to stop processing of the function and return..

It's a display override.. which ends up calling the fetch override (as all displays are really fetches.. and then it just dies right there)..

Any ideas?

I have commented out the line and all appears to work well.. but it worries me to have done so.

How do your display() and fetch() functions look like?

LIke this:

Code:
function display($var) {

      if (SD_IS_MOBILE) {
         return parent::display($var, "m","m");
      } else {
         return parent::display($var, "d","d");
      }

   }
   

   
   function fetch($var) {

      if (SD_IS_MOBILE) {
         return parent::fetch($var, "m","m");
      } else {
         return parent::fetch($var, "d","d");
      }

   }

display() does call fetch( ) with setting the $display parameter true. Now you have overloaded the fetch() and the $display parameter is not handled any longer.

Your implemetation does also break correct variable scoping when using subtemplates.

Instead of overloading display() and fetch() do in the main script

Code:
if (SD_IS_MOBILE) {
         $smarty->compile_id = 'm';
         $smarty->cache_id = 'm';
} else {
         $smarty->compile_id = 'd';
         $smarty->cache_id = 'd';
}
