Smarty fetch function active secure_mode

[Matthias de MAUROY - CYIM]

Hello everyone !

I hope my silly question will get answers from some of you...

I'm just trying to send an email using smarty basics functions such as using {php} tags and playing php in smarty tags {if strstr($email, '@')}.

But each time I try to send the template Smarty activate secure_mode and everything's ruined...

I found where Smarty put the secure_mode but I can't understand why... (in CRM/Core/Smarty.php line 202).

If someone ever run into this and solved it pleeeease help me 

PS : I defined this in my settings file => define( 'CIVICRM_MAIL_SMARTY', 1 );

Still working on it !

I hope i'll find the solution
