Repeating Group Field with Taxonomy Select

    Hi, cheers for the plugin!

    As the title suggests, I’m having an issue using repeating group fields which contain a taxonomy select/radio field.

    The taxonomy select does not act independently and acts as if it is just the same field repeated. I.E: only 1 taxonomy term will updated to the post, and all select fields will reflect this once the post is updated. The field that will be selected will be the last one in the list.

    I can’t find any information with regards to taxonomy fields not being supported in repeating groups, so please forgive me if that is the case.

    According to the following url
    https://github.com/WebDevStudios/CMB2/wiki/Field-Types

    Those two field types aren’t available as repeatable fields. They both have an asterisk next to them, and at the bottom of the initial list is this note:

    * Not available as a repeatable field

    Doh!

    Cheers for the heads up Michael, I completely missed that info. Thanks.

    Hi
    Just in case anybody requires this functionality, I have a solution that works – if there is a better method please let me know.
    Essentially just involves populating a select field in a repeating group with get_terms().

    You will first have to select the terms for the post (and update post). Not ideal but it works. Ensures that you manually have added the taxonomy first.

    function customprefix_get_tax_array(  ) {
     $taxonomies = array(
         'custom_tax',
     );

    $args = array(
     'orderby'           => 'id',
     'order'             => 'ASC',
     'fields'            => 'id=>name',
     'hierarchical'      => false,
    );

  return get_terms( $taxonomies, $args );

}

    and call above function in the select field

    $cmb_work_group->add_group_field( $group_field_id, array(
	'name'     => __( 'Test Tax Select', 'cmb2' ),
	'desc'     => __( 'field description (optional)', 'cmb2' ),
	'id'       => 'select',
	'type'        => 'select',
	'show_option_none' => true,
    	'options'  => customprefix_get_tax_array(),
) );

    After some inspection the above doesn’t work quite as expected, get_terms returns all terms used by all posts.

    A better method is:

    function customprefix_get_tax_array( $cmb ) {
	$taxonomies = array(
            'custom_tax',
	);
	$args = array(
            'fields'  => 'names',
	);
	return wp_get_post_terms( $cmb->object_id, $taxonomies, $args );
}

    and …

    $cmb_work_group->add_group_field( $group_field_id, array(
	'name'     => __( 'Test Tax Select', 'cmb2' ),
	'id'       => 'select',
	'type'        => 'select',
	'show_option_none' => true,
    	'options'  => 'customprefix_get_tax_array',
) );

    They already have a solution in the Tips and Tricks page:

    A dropdown for taxonomy terms which does NOT set the term on the post
