Im trying to set a custom post title with a custom field instead of typing the title im setting it with a custom field it works good if I use a type text custom field but once I use a relationship field Im getting nothing I guess because that field return a array, my relationship field is "route_affected_by_this_alert"
// Auto fill Title and Slug for CPT's - 'alerts'
function lh_acf_save_post( $post_id ) {
// Don't do this on the ACF post type
// if ( get_post_type( $post_id ) == 'project' ) {
// return;
// }
$new_title = '';
$new_slug = '';
// Get title from 'alerts' CPT acf field 'route_affected_by_this_alert' if ( get_post_type( $post_id ) == 'alerts' ) { $new_title = get_field( 'route_affected_by_this_alert', $post_id ); $new_slug = sanitize_title( $new_title ); }
// Prevent iInfinite looping...
remove_action( 'acf/save_post', 'lh_acf_save_post' );
// Grab post data
$post = array(
'ID' => $post_id,
'post_title' => $new_title,
'post_name' => $new_slug,
);
// Update the Post
wp_update_post( $post );
// Continue save action
add_action( 'acf/save_post', 'lh_save_post' );
// Set the return URL in case of 'new' post
$_POST['return'] = add_query_arg( 'updated', 'true', get_permalink( $post_id ) );
}
add_action( 'acf/save_post', 'lh_acf_save_post', 10, 1 );
I want to assign those names to the post title
This is what im getting:

you don't need a function...
$my_query = get_posts(array(
'post_type' => 'post_type_name',
'meta_query' => array(
array(
'key' => 'relationship_field_name',
'value' => get_the_ID(),
'compare' => 'LIKE'
)
)
));
foreach( $my_query as $object ):
print_r($object); //you'll see everything about the single post
$object_title = $object->post_title; //title
$object_acf_field = get_field('acf_field_name',$object->ID); //any ACF field
endforeach;
