Custom post type split title, setup permalink accordingly

Question

I am currently working on a project, where I need to do this -

• Create a custom post type called authors
• Create first name and last name field for authors
• Single author permalink structure must be first_name_field-last_name_field. e.g - author Arafat Jamil must have permalink arafat-jamil

How can I achieve this? Third party plugins must not be used, but you can name plugins, I can take the functionality out of it.

Answer 1

I have been working on this solution, I have come up with a different idea to implement this -

I have added two different meta boxes, one with First Name, the other with Last Name

Then I have hooked a function with save_post_{$post->post_type} hook like this -

add_action( "save_post_{$post->post_type}", "update_post_data" );

function update_post_data( $post_id ) {
    // Unhook to stop infinite loop.
    remove_action(  "save_post_{$post->post_type}", "update_post_data" );

    $fname = sanitize_title( get_post_meta( $post_id, '_first_name', true ) );
    $lname = sanitize_title( get_post_meta( $post_id, '_last_name', true ) );

    $post_title = ucwords( $fname . ' ' . $lname );
    $post_name  = $fname . '-' . $lname;

    $args = [
        'post_title' => $post_title,
        'post_name'  => $post_name,
    ];

    // Update post data.
    wp_update_post( $args );

    // Re-hook the function, to make it work in future.
    add_action( "save_post_{$post->post_type}", "update_post_data" );
}
