How to use Post Custom Metadata in Post Titles and Post Permalinks

Question

I am very new to WordPress. How can I use post custom metadata in place of Post Titles, and as the Post Permalink? For example, instead of domain.com/the-post-title, the permalink would be domain.com/$postcustommetadata.

I posted my idea in the WPORG support forums. I have a general idea, but don't know how to implement it, because I don't yet fully understand WordPress conventions, classes, etc.

Thanks

Answer 1

This will do.

The slug is saved on the wp_posts while custom fields are on the wp_posts_meta. If you want to make it like that you can use an action hook on save_post that will get the value of the custom fields and saves it as the post slug.

Here is the code

add_action('save_post', 'set_slug');

function set_slug($post_id){
    $new_slug = get_post_meta($post_id,'custom-slug', true);    
    $post_args = array(
        'ID' => $post_id,
        'post_name' => $new_slug,
    );

    wp_update_post($post_args);
}

If you're looking for customizing the permalink for specific posts, pages or categories, try the Custom Permalinks plugin. I've had much success with it before.
