Custom field for CMB2 to attach posts to each others.

Same approach than CMB2 Attached Posts Field with Ajax request, multiple/single option, and different UI.


You can install this field type as you would a WordPress plugin:

  • Download the plugin
  • Place the plugin folder in your /wp-content/plugins/ directory
  • Activate the plugin in the Plugin dashboard

Composer Intallation:

composer require alexis-magina/cmb2-field-post-search-ajax:dev-master

Usage - Admin

Follow the example in example-field-setup.php for a demonstration.

Options :

  • limit (int, default = 1 : single selection) : limit the number of posts that can be selected
  • sortable (bool, default = false) : Allow selected posts to be sort
  • query_args (array) : setup the ajax search query : pass a wp_query args array.

Filter : (since 1.1.2) Ajax results can be filtered to customize returned text and posts values. Use filter "mag_cmb_post_search_ajax_result", for example :

function example_callback( $arr ) {
	// $arr['data'] : contains post_id
	// $arr['guid'] : contains admin edit post url
	// $arr['value'] : contains post title
	$arr['value'] = 'Custom string '.$arr['value'];
    return $arr;
add_filter( 'mag_cmb_post_search_ajax_result', 'example_callback' );

Usage - FrontEnd

You can retrieve the meta data using get_post_meta( get_the_ID(), 'your_field_id', true );

If field limit > 1, this will return an array of attached post IDs. If field limit == 1, this will return only the single attached post ID.
