Smarty

[bolnikh]

We have template "loop.tpl".
--------- loop.tpl --------
<h1>Loop</h1>

{include file="loop.tpl"}
----------

It include herself - and we have infinity loop, memory finished error and so on.

PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to all
ocate 16384 bytes) in C:\home\test_smarty\Smarty-3.1.21\libs\sysplugins\smarty_i
nternal_templatebase.php on line 180


How can I detect and prevent this situation? I have user edited templates and user can do error. I want to produce exception like "We have infinity loop error", not just crash with memory error


Thanks

Smarty itself has no way to to detect it. Many users have wanted recursion and deep nesting levels of their templates. If xdebug is installed you can set the xdebug.max_nesting_level paramater in php.ini (default 100) to limit the nestinf of php function calls. But reducing that is also not a good idea as you could run into that limit during template compilations.

So no real solution.
