Parametric Search in Low Search

Question

I have this search form in test/low-search-test

{exp:low_search:form collection="foo" secure="no" search_mode="all" result_page="test/low-search-test-results"}
<fieldset>
    <label>Job:</label>
    <select name="job" dir="ltr" id="job">
    {exp:low_options:job}
         {options}
            <option value="{option:value}">{option:label}</option>
        {/options}
    {/exp:low_options:job}
    </select>
</fieldset>
<button type="submit">Search</button>
{/exp:low_search:form}

and the results form in test/low-search-test-results

{exp:low_search:results}
  {if count ==  1}<ol>{/if}
    <li><a href="{comment_url_title_auto_path}">{title}</a></li>
  {if count == total_results}</ol>{/if}
  {if no_results}No search results{/if}
{/exp:low_search:results}

My problem is that the results page does not filter by job.It doesn't even respect the "collections" param in the search form. It returns all results including some channel entries not defined in the collections param.

Am I doing something wrong here? How do I filter results in Low Search based on their Channel Fields?

Answer 1

You need to add the query="" parameter to the Results tag so it knows what has been submitted.

Also, if you're searching a specific custom field, use the input name as though it was a parameter in the channel:entries tag. For example, this:

{exp:channel:entries channel="foo" search:some_field="bar"}

Would become this in a Low Search form:

<select name="search:some_field">
    <option value="foo">Foo</option>
</select>

So, in your case, you'd need to use name="search:job" in your select-element.

But all of that will be ignored anyway if you don't add the query="{segment_3}" parameter to the Results tag (where {segment_3} is the reference to the encoded query in the URI).
