My HTML Code looks like this:

...
<select class="material tags" name="search:material_tag" data-placeholder="Tags" tabindex="4" multiple>
 <option value="not IS_EMPTY">all</option>
{exp:tag:cloud channel="material" most_popular="100"}
 <option value="{tag}">{tag}</option>
{/exp:tag:cloud}
</select>...

So I got a multiple select here.
You can ignore the exp:tag:cloud tag, since the problem also occures with an undynamic set of tags.

The “dynamic_parameters” on the other hand gives me the search on the custom field that I need:

{exp:channel:entries channel="material"
 dynamic_parameters="search:material_tag"
 orderby="date" sort="desc" limit="10"}
...code here…
{/exp:channel:entries}

But the search only passes me the last parameter of my input and the search fails.

I tried to use:

name="search:material_tag[]"

and

dynamic_parameters="search:material_tag[]

instead.

Without any effect.

Anyone any idea?

With the “output profiler” turned on I can see the paramaters are correct:

POST DATA
<pre><code> 
$_POST[‘search:material_tag’] 
Array
(
  [0] => tag1
  [1] => tag2
)<pre><code>

But still unsuccessfull with the search

Hi Komtur,

The dynamic parameters don’t support multi-selects (basically, they don’t support arrays in the post value).  Just brainstorming…..

If you turn php parsing ‘on’ and redefine your post:

<?php

$_POST['search:material_tag'] = implode('|', $_POST['material_tag']);

?>

Note- I renamed the post to avoid conflicts.

I don’t entirely love this approach, but I suspect it will work.

Does it make sense what’s going on there?

This works. Thanx.

😉  Thanks for the confirmation.  If you run into any more issues, just let us know!
