{if not isset}聪明的人 [英] {if not isset} Smarty

问题描述

if (!isset($var)){的smarty代码是什么?

what is the code for smarty for if (!isset($var)){ ?

如果在smarty中未定义$ x时使用{if $ x eq'5'}，则会给出错误function call 'get_template_vars' is unknown or deprecated..这就是我所相信的，只要我对试图知道此错误是从何而来就失去了希望！

if using {if $x eq '5'} when $x is not defined in smarty , it gives an error function call 'get_template_vars' is unknown or deprecated. . this is what i believe so far as i lost hope in trying to know where did this error come from !

谢谢.
