Show List of Items from Component in Module Select

Show List of Items from Component in Module Select

2 years 8 months ago - 2 years 8 months ago #1780 by Matthew Jones

I have a component where the user can enter a list of locations. In the module, I want them to be able to select a single location in the "item" tab. Currently there is a text field there requesting the item's ID. I want to replace that with a dropdown list of ll the items (locations) that were entered in the component.

Can someone point me in the right direction of how to do this?

Here's what I have so far:



// No direct access to this file
defined('_JEXEC') or die('Restricted access');


class JFormFieldSingleLocation extends JFormFieldList {
	 * The field type.
	 * @var         string
	protected $type = 'SingleLocation';

	 * Method to get a list of options for a list input.
	 * @return  array  An array of JHtml options.
	protected function getOptions()
		$db    = JFactory::getDBO();
		$query = $db->getQuery(true);
		$db->setQuery((string) $query);
		$locations = $db->loadObjectList();
		$options  = array();

		if ($locations)
			foreach ($locations as $location)
				$options[] = JHtml::_('select.option', $location->id, $location->locationname);

		$options = array_merge(parent::getOptions(), $options);

		return $options;

I then added the following to /com_name/modules/mod_name/mod_name.xml
                    name="item_table" type="list"

	                  <option value="#__name_location">#__name_location</option>

                <field name="item_id" type="SingleLocation" label="Location"
	                 description="Location you want to display"
	                  required="true" />

All I get when I look at the module though is a textbox instead of a dropdown.

Figured it out. I needed to name the file singlelocation.php instead of SingleLocation.php.
