gform_pre_render and multiselect

Gravity Support Forums » Plugin Support » Gravity Forms

I am generating a multiselect field based on subcategories.

add_filter('gform_pre_render_1', 'amenities');
function amenities($form){

	$amenities = get_categories(array('child_of' => 15, 'order_by' => 'name', 'hide_empty' => 0));
	$amenities_choices = array();
	foreach ($amenities as $amenity) {
		$amenities_choices[] = array('text' => $amenity->name, 'value' => $amenity->term_id);
	}

	foreach($form['fields'] as &$field) {
		if($field['id'] == 12) {
			$field['choices'] = $amenities_choices;
		}
	}

	return $form;
}

This works great. The problem is that on the creation of the form, I only have one "item" on the multiselect. So when processing Gforms only checks for one. I am looking for something that can be adjusted via a filter so it will process numbers based on the newly generated multiselect options.

Found another filter that works. "gform_pre_submission_filter_1" You also have to modify the "inputs" array for it to work though.

add_filter("gform_admin_pre_render", "amenities");
add_filter("gform_pre_submission_filter_1", "amenities");
add_filter('gform_pre_render_1', 'amenities');
function amenities($form){

	$amenities = get_categories(array('child_of' => 15, 'order_by' => 'name', 'hide_empty' => 0));
	$amenities_choices = array();
	$amenities_inputs = array();
	$i = 1;
	foreach ($amenities as $amenity) {
		$amenities_choices[] = array('text' => $amenity->name, 'value' => $amenity->term_id);
		$amenities_inputs[] = array('id' => '12.'.$i, 'label' => $amenity->name, 'name' => '');
		$i++;
	}

	foreach($form['fields'] as &$field) {
		if($field['id'] == 12) {
			$field['choices'] = $amenities_choices;
			$field['inputs'] = $amenities_inputs;
		}
	}
	//ri_echo($form);
	return $form;
}
