I'm using Custom Metaboxes 2 and I can't get repeatable group values to display on the front end. I have a repeatable group with a single text field.
I have the backend code first, followed the front end code.
add_action( 'cmb2_init', 'awc_register_repeatable_group_field_metabox' );
function awc_register_repeatable_group_field_metabox() {
// Start with an underscore to hide fields from custom fields list
$prefix = '_awc_';
/**
* Repeatable Field Groups
*/
$cmb_group = new_cmb2_box( array(
'id' => $prefix . 'songs',
'title' => __( 'Track Listing', 'cmb2' ),
'object_types' => array( 'awc_discography', ),
) );
// $group_field_id is the field id string, so in this case: $prefix . 'demo'
$group_field_id = $cmb_group->add_field( array(
'id' => $prefix . 'demo',
'type' => 'group',
//'description' => __( 'Generates reusable form entries', 'cmb2' ),
'options' => array(
'group_title' => __( 'Track {#}', 'cmb2' ), // {#} gets replaced by row number
'add_button' => __( 'Add Another Track', 'cmb2' ),
'remove_button' => __( 'Remove Track', 'cmb2' ),
'sortable' => true, // beta
),
) );
/**
* Group fields works the same, except ids only need
* to be unique to the group. Prefix is not needed.
*
* The parent field's id needs to be passed as the first argument.
*/
$cmb_group->add_group_field( $group_field_id, array(
'name' => __( 'Title', 'cmb2' ),
'id' => 'title',
'type' => 'text',
) );
}
FRONT END:
$entries = get_post_meta( get_the_ID(), $prefix . 'songs', true );
foreach ( (array) $entries as $key => $entry ) {
$songtitle = '';
if ( isset( $entry['demo'] ) )
$title = esc_html( $entry['demo'] );
// Do something with the data
echo $title; // Don't know if this is the correct method.
}
Do you have
$prefix
defined in your front end code? That's the only thing I can see being wrong there. If$prefix
isn't defined, you're looking up the post_meta with keysongs
instead of_awc_songs
.
