I’m using the cmb2 plugin and am struggling to make it save my data and display it on the front end.

My code for the functions.php file of the plugin:

add_action( ‘cmb2_init’, ‘cmb2_listingpro’ );

function cmb2_listingpro() {
$prefix = ‘_listingpro_’;
$cmb = new_cmb2_box([
‘id’ => ‘listingpro_dates’,
‘title’ => __( ‘Dates Listing is Available’, ‘cmb2’ ),
‘object_types’ => array( ‘listing’, ),
‘context’ => ‘advanced’,
‘priority’ => ‘high’,
‘show_names’ => true,
]);

$cmb_group_id = $cmb->add_field([
‘id’ => ‘dates’,
‘type’ => ‘group’,
‘options’ => [
‘group_title’ => __(‘Dates {#}’, ‘text_domain’),
‘add_button’ => __(‘New Date’, ‘text_domain’),
‘remove_button’ => __(‘Remove Date’, ‘text_domain’)
]
]);

$cmb->add_group_field($cmb_group_id, [
‘name’ => ‘Test Date Picker’,
‘id’ => ‘date_text’,
‘type’ => ‘text_date’,
]);

The site has a ‘create a new listing page’ and ‘edit listing page’.
I’ve added this code to files that control both pages:

global $listingpro_options;
$object_id = 2;
$metabox_id = ‘listingpro_dates’;
$mylisting = cmb2_metabox_form( ‘listingpro_dates’, $object_id );

The problem with these pages is that the data won’t save. Am I missing something here?

Finally, on the page that displays the final listing, I’ve added this code to the php file to display the data from the metabox.

add_action(‘init’, ‘listingpro_dates2’, 0 );

function listingpro_dates2() {
$term_id = get_queried_object()->term_id;
$dateslist = get_term_meta( $term_id, ‘_listingpro_dates’, true );
if ( is_category() ) {
if ( $dateslist ) {
echo $dateslist;
}
}

}

Nothing from the metabox shows up on this page. Maybe because the data isn’t saving?
Also, I’m not too sure if I used the $tag/hook of the add_action() function correctly.

Any help is greatly appreciated. Thanks.
