CMB2 Attached Posts Field
Custom field for CMB2.
The post IDs are saved in an array, which can be rearranged by dragging and dropping posts in the attached posts column.
If the ability to search for a post and attach it is more in line with what you need, you might consider CMB2 Post Search field instead.
Installation
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.
Customization
The example demonstrates how to modify the get_posts
query args, and allows you to toggle the thumbnails display as well as a filter search input.
Usage
You can retrieve the meta data using the following:
$attached = get_post_meta( get_the_ID(), '_attached_cmb2_attached_posts', true );
This will return an array of attached post IDs. You can loop through those post IDs like the following example:
foreach ( $attached as $attached_post ) {
$post = get_post( $attached_post );
}
Once you have the post data for the post ID, you can proceed with the desired functionality relating to each attached post.
