Adding metabox field data to the post title

Hi Ben,

You can use the action rwmb_{$meta_box_id}_after_save_post and the function wp_update_post() to update the post title after saving a specific meta box.

Here is the sample code:

add_action( 'rwmb_versionning_after_save_post', 'update_post_title' );

function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'version', '', $post_id );

    // Get the post title
    $my_post_title = get_the_title( $post_id );
    
    // Preprare update post
    $my_post = array(
        'ID' => $post_id,
        'post_title' => $my_post_title . ' ' . $my_meta,
    );

    wp_update_post( $my_post );
}

Where can I find $meta_box_id ?

Hi Long,

I am also trying to do this. But I need some help with the above sample code and documentation. Can you possibly indicate which elements I need to customise and with exactly what. It is really helpful when you can add //update this variable with your meta-box-id. I am very new to this and so nothing is obvious to me.

I will also need to do this for post excerpt and post content...

Many thanks!
Yasmine

Hi Long,

I just saw your reply. Thank you. Here is my PHP:

Thank you again Long.

And would it be the same logic for post_content? And excerpt? Eg:

add_action( 'rwmb_research-summary_after_save_post', 'update_post_content' );

function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'academicpost_content', '', $post_id );

// Prepare update post
$my_post = array(
    'ID' => $post_id,
    'post_content' => $my_meta,
);
wp_update_post( $my_post );
}

Thanks ... I don't understand how to apply the documentation - hence my question... Is this correct?

add_action( 'rwmb_research-summary_after_save_post', 'update_post_content' );

function update_post_content( $post_id ) {
    $my_meta = rwmb_meta( 'academicpost_content', '', $post_id );

$my_post = array(
    'ID' => $post_id,
    'post_content' => $my_meta,
);
wp_update_post( $my_post );
}

If I wanted to combine two field_id's to create a custom title how would I go about merging them? For instance, I have first_name and then last_name. I want both of these to show in post_title together.

Also can that be applied to rewrite the slug of the post? Right now it displays as auto-draft.
