Custom field for the wordpress CMB2 plugin.
cmb2-magicsuggest turns the magicsuggest script by Nicolas Bize into a custom field type that can be added to your metaboxes.
The magicselect field acts much like a select/multiselect field but with a typeahead-style search, allowing you to select items from a list of suggestions.
This field can also be configured to :
- allow the user to enter non-suggested entries.
- set the limit of items that can be selected.
- allow the user to reenter the same entry multiple times.
Follow the example in example-field-setup.php for a demonstration. The example assumes you have both CMB2 and this extension in your mu-plugins directory. If you're using CMB2 installed as a plugin, remove lines 6-9 of the example.
The example includes two configuration demos of the Magic Suggest custom field.
You can retrieve the meta data using the following:
$fruits = get_post_meta( get_the_ID(), '_cmb2_magicsuggest_demo_fruits', true );This will return an array of string.
$related_posts = get_post_meta( get_the_ID(), '_cmb2_magicsuggest_demo_related_posts', true );This will return an array of related post IDs. You can loop through those post IDs like the following example:
foreach ( $related_posts as $related_post ) {
$post = get_post( $related_post );
}Once you have the post data for the post ID, you can proceed with the desired functionality relating to each attached post.
cmb2-magicsuggest does not support all of the magicsuggest API configuration options but only the few that I needed.
