Using XPDO getvalue to retrieve select field with options (tags)

In a posthook I'm using getvalue to retrieve the values of a form. For normal fields there's no problem.

$name =  $hook->getValue('name');

But I also have a select field with different options that I use as tags. So the client can select more than one options in the list. (I use the jquery Select2)

<select name="source[]" multiple="multiple">
<option value="Google" [[!+fi.source:FormItIsSelected=`Google`]]>Google</option>
<option value="Facebook" [[!+fi.source:FormItIsSelected=`Facebook`]]>Facebook</option>
<option value="Twitter" [[!+fi.source:FormItIsSelected=`Twitter`]]>Twitter</option>
</select>

$source =  $hook->getValue('source');

How can I get this array from this form? getValue doesn't seem to work (stays empty). Can't find any docs on it how to do this, hope somebody can help. [ed. note: sitsol last edited this post 7 years, 7 months ago.]

Hi, I've never done a posthook, but the name of your field is source[] and not source. Have you tried to change this ?

It has nothing to do with the fact that it's a prehook or posthook. I just want to get the values from the select-list. My field is source[] because it's an array (otherwise I only get the last selected option) and that's the problem with the getValue. How do I get an array with getValue?

$source =  $hook->getValue('source'); doesn't work
$source =  $hook->getValue('source[]'); doesn't work
$source[] =  $hook->getValue('source[]'); doesn't work
$source[] =  $hook->getValue('source'); doesn't work

I think it must be done with something else than getValue, but can't find any information on it.

For the moment, because I couldn't find a solution, I did it in another way by adding the value of the option-list to a hidden field with jquery and then read that hidden field with getValue.
