PHP Error: Invalid EE Conditional Variable

Trent 24 Apr 2016 07:48 problem, complete

I am using EE2.8.1 with Low Search 4.4.3

This is my first time playing with Low Search.
I am playing with the Categories example: http://gotolow.com/addons/low-search/...

I am getting the following PHP error which this code is the culprit.

{if low_search_category ~ '/\b'.category_id.'\b/'} checked{/if}

Full PHP error is:

A PHP Error was encountered
Severity: User Warning
Message: Invalid EE Conditional Variable: {if "9|11" ~ '/\b'.category_id.'\b/'}
Filename: libraries/Functions.php
Line Number: 2640

A PHP Error was encountered

   EE2.8 and below don't support those conditionals. As the top of the example page states:
   
   

   Note: these examples feature conditionals using the Matches Operator introduced in EE 2.9.0. If you’re using an older version of ExpressionEngine, you can use the IN conditionals instead.

   
   
   So try and use the IN syntax instead: http://gotolow.com/addons/low-search/...
   
   And here's a blog post about the change in conditionals: http://gotolow.com/blog/conditional-c...

   Perfect, thank you Lodewijk.
   That did the trick, apologies for not seeing that one.
