low search: using checkboxes to filter by category groups

pirco 7 Nov 2013 05:15 question, complete

I'm using category groups to filter search results just like the documentation shows but want to use checkboxes instead of a select box. it's working but on the results page, the originally selected filters are not checked anymore (so when I checked on category X then the search results actually do filter by category X but the checkbox isn't marked).

is there something I need to change?

{exp:channel:categories channel="installations|lighting" style="linear" category_group="2"}
< input type="checkbox" name="category:style[]" value="{category_id}"
{if category_id IN ({low_search_category})} checked="checked"{/if} / > {category_name}
{/exp:channel:categories}

on topic: what's the difference between name="category:style[]" and name="category:style" ?

thanks

   The variable name should match the input name (without square brackets), so use this conditional instead:
   
   

   {if category IN ({low_search_category:style})}checked="checked"{/if}

   
   
   The square brackets make the input return an array instead of a single value, so that's needed if you want to submit multiple values for a single parameter.

   makes perfect sense now :-)
   
   brilliant.

   Hi, I'm looking for a similar result but get an error when I add in the conditional:
   
   "You have an invalid conditional in your template. Please review your conditionals for an unclosed string, invalid operators, a missing }, or a missing {/if}.
   
   Parser State: Unexpected ‘IN’ (VARIABLE); expected RD in Snippet “sn-sidebar-projects” on line 10."
   
   Here's my code (hopefully..I'm forever forgetting how to properly include it):
   
   
{exp:channel:categories category_group="8" id="filter"}
<input type="checkbox" name="category:region[]" value="{category_id}" {if category IN ({low_search_category:region})} checked="checked"{/if}>
<label for="category:region[]">{category_name}</label>
{/exp:channel:categories}

   
   Any tips?

   You're probably on EE2.9+, where IN conditionals break.

   Thank you!
   
   For anyone reading who had this problem, the code that worked for me was:
   
   
<input type="checkbox" name="category:region[]" value="{category_id}"{if low_search_category:region ~ '/(^|\|)'.category_id.'($|\|)/'}checked="checked"{/if}>
