Get value from HTML multi select

[danieltj]

I have a multi-select element and I'm trying to capture the values in it but it's not working and I've got no idea why the value isn't getting passed through to the $request variable. I'm sure I'm missing something very simple.

The HTML from my template:

Code: Select all

<select name="group_membership[]" id="group_membership" multiple="multiple" size="10">
	{% for group in GROUPS %}
		<option value="{{ group.id }}">{{ group.name }}</option>
	{% endfor %}
</select>

This is how I'm trying to capture the values in my controller.

Code: Select all

$memberships = $request->variable( 'group_membership', '' );
var_dump( $memberships ); die();

This is what the var_dump() is outputting.

Code: Select all

/Users/danieltj/Local Sites/phpbb/app/public/ext/danieltj/extension/controller/acp.php:161:string '' (length=0)

Any ideas what I'm doing wrong?

it is a array of string (Or array of ints by the look of the field name), so you second parameter of variable should be a array of string as well.

$request->variable( 'group_membership', [ 0 ] )

That fixed it, thank you.
