isset variable variable error

[ransom85]

I have test for exists variable variable - {if isset($rfc822Name_err_{$key})}
For smarty verison 3.1.29 code works fine. But from version 3.1.30 generated php code cause error - Undefined index: rfc822Name_err_0.
PHP source coude for 3.1.29:

tpl_vars['rfc822Name_err_'.($_smarty_tpl->tpl_vars['key']->value)]->value)) { PHP source coude for 3.1.32: tpl_vars['rfc822Name_err_'.($_smarty_tpl->tpl_vars['key']->value)]->value !== null ))) {

I had the same phenomenon starting with Smarty 3.1.31 when using isset in a foreach or section loop and opened an issue about that here #453 - I think these two issues could be related because its also some kind of a var var situation.

Unfortunately I haven't found the reason of that problem myself yet but I thought if you want to subscribe to that maybe related issue too I link it for you here. 🙂

This indeed seems to be a duplicate. See #567
