Description of the Code
Purpose: Automatically updates the “location” field of an event post based on the “location” metadata of a related post (e.g., a bar or restaurant organizing the event).
Triggers:The function update_event_location is executed when an event post is submitted or updated.
Process:Verifies that the post type is events.
Extracts the related post ID from the custom field post-relation.
Retrieves the location metadata (stored as JSON) from the related post.
Decodes the JSON data and updates the location field in the current event post.
Compact Logic: The function is designed to handle the process efficiently, with clear validations and minimal overhead.
add_action( 'voxel/app-events/post-types/events/post:submitted', 'update_event_location' );
add_action( 'voxel/app-events/post-types/events/post:updated', 'update_event_location' );function update_event_location( $event ) {
$post = $event->post;// Ensure the post type is 'events'
if ( $post->post_type->get_key() !== 'events' ) {
return;
}// Get the related post ID from the 'post-relation' field
$relation_id = $post->get_field('post-relation')->get_value()[0] ?? null;if ( $relation_id ) {
// Retrieve and update the 'location' field if it exists
$location = json_decode( get_post_meta( $relation_id, 'location', true ), true );
if ( $location ) {
$post->get_field('location')->update( $location );
}
