I'm using class constant with php5 (usefull to keep the code clean).
There is a problem then trying using them inside template.

Class definition:
Code:
Class Article {
  const ONLINE=0;
  const OFFLINE=1;
  var $etat=0;
}


Template:
Code:
 {if $article->etat == Article::ONLINE}online{else}offline{/if}


Smarty don't recognise this way off using a class constante, I got the error:
syntax error: unidentified token '::ONLINE'

Then I look at the code generate, Smarty have create that:
Code:
<?php if ($this->_tpl_vars['article']->'etat == Article ::ONLINE): ?>

Note the 'space' before the ::

Class constant is very usefull then writing oo code. It help keeping the code clean and ease the reading of old code. Could it be possible to resolve this issue.
Is seems that the result code work beside the Smarty Error message.

Thx for the work done. I only use Smarty now, on all my project Smile

This is not a bug. PHP5 class constants are simply not supported in Smarty (Smarty is a PHP4 library). Furthormore, that style of constant access is not supported by Smarty either (you need to access global constants via the $smarty variable as described in the manual).

The next major release will likely address this but how and where has not been decided -- while class constants make a lot of sense for PHP5 class code, they make much less sense for a template system that is supposed to abstract application details away from the template user.
