I had a custom post type that only used custom fields, so I needed to generate a post title from there.
Here’s one way. You can if course chain as many if else as you want to check other types.
functions.php
function custom_post_type_title($post_id)
{
global $wpdb;
if (get_post_type($post_id) == 'staff') {
$name = get_post_custom_values('name');
$title = $name[0];
$where = array('ID' => $post_id);
$wpdb->update($wpdb->posts, array('post_title' => $title), $where);
}
}
add_action('save_post', 'custom_post_type_title');
Is this supposed to overwrite the blank post_title in the database? It doesn’t seem to work for me. My issue is that I am trying to use post relationships between one cpt to another. But the dropdown that shows post relationships shows blank options because it pulls the post_title from the database.
Oh I see, it only applies if it is an update and not an initial publish. Is there a way to make this happen when a post is published, as opposed to updated?
This should actually work when publishing. Don’t know about your particular case, but if I remember correctly I just call this function (passing the post id) when a post is created.
