Querying and looping categories or posts within a complex/select field

Hi @peperene5150,

You are close to what you need but calling foreach inside an array declaration is not valid php syntax which is what causes the error.

I’ve updated your code here which should do the job:

function get_category_options() {
	$argsCat = array(
	    'orderby' => 'ID',
	    'order' => 'ASC'
	);
	$categories = get_categories( $argsCat );

	$options = array();
	foreach ($categories as $term) {
		$options[ $term->term_id ] = $term->name;
	}
	return $options;
}

// My field
Container::make('post_meta', __( 'My field' ) )
    ->show_on_post_type('page')
    ->add_fields( array(

        // gallery
        Field::make( 'complex', 'h_hero_slider', __( 'Ajouter un slide' ) )
            ->add_fields( '', [
                Field::make( 'select', 'cat', 'Catégorie slider' )
                ->set_width(50)
                ->add_options( 'get_category_options' )
                ->set_required( true ),
            ]),
    ));

In this case we’re making use of the ability of add_options to accept a function as it’s argument so that it lazyloads the options instead of loading them on every pageload.
