php - Test if a cookie exist with it name in a variable -

-

i'd test if cookie exists, pretty basic, know, doesn't want work well. so, here pieces of code related:

<?php $quesid = the_id()."gcquestion"; if(isset($_cookie[$quesid])){   ... }

the test fails, when cookie's name match generated variable. weird part when try type variable name hand if(isset($_cookie["94gcquestion"])), works.

question : can use variable name $_cookie ?

assuming you're using wordpress,

the_id(): displays numeric id of current post. tag must within loop.

the_id() template function , print id, doesn't return it.

to return id, use get_the_id() instead.

<?php $quesid = get_the_id()."gcquestion"; if(isset($_cookie[$quesid])){   ... }
