Hi,

When I publish a post, I would to add to the post title, the version of the document (metabox 'version').
How can I add the data from the 'versionning' field to the post title ?
Like this : POST_TITLE 'version'

$meta_boxes[] = [
'title' => esc_html__( 'Version', 'text-domain' ),
'id' => 'versionning',
'post_types' => ['docs'],
'context' => 'side',
'priority' => 'high',
'fields' => [
[
'id' => $prefix . 'version',
'name' => "Version",
'type' => 'text',
'step' => "0.01",
'required' => 1,
],
],
];

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 );
}
```

Hi Alperen,

It's the field group ID if you use the Builder, please follow this documentation to get more details https://docs.metabox.io/creating-meta-boxes/

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 Yasmine,

If you are using the builder, you can share the code that creates meta box (field group) and custom fields on your site. I will help you to indicate the meta box ID.

Hi Yasmine,

If you want to update the post title by the field Research Title value, here is the code:
```
add_action( 'rwmb_research-summary_after_save_post', 'update_post_title' );

function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'academicpost_title', '', $post_id ); //include the $prefix academic to the field ID
    
    // Preprare update post
    $my_post = array(
        'ID' => $post_id,
        'post_title' => $my_meta,
    );
    wp_update_post( $my_post );
}
```

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 );
}
```

Hi,

Yes, it will work with post_content or other post elements. Please read more on the documentation https://developer.wordpress.org/reference/functions/wp_insert_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 );
}
```
