Hi there

I would like to be able to set the value of a toolset custom field, assigned to the woocommerce order post, in the moment the order is created. I think I need something like a save to post action in php functions? The custom field is a select field with the values: 1, 2, 3, 4 and I would like the new order save the value of '1' when it is created.

Is this possible? Maybe its not possible... I can't seem to find anyone else in our support community asking this same question...

Thanks in advance!

Rita

Hello, yes you can use the WordPress hook save_post to set a custom field value automatically when an Order is created from the front-end of the site. This hook is documented here: https://developer.wordpress.org/reference/hooks/save_post/

I have some example code you can use. Replace custom-field-slug with the slug of your custom field as defined in wp-admin (do not include the wpcf- prefix here), then place this code in your child theme's functions.php file or in a new custom code snippet in Toolset > Settings > Custom Code:

function tssupp_set_select_value_1 ( $post_id, $post, $update ) {
  $field_slug = 'custom-field-slug';
  $forced_value = '1';
  $post_type_slug = 'shop_order';

  // you should not edit anything below this line

  // - bail on wrong post type or on update
  $post_type = get_post_type( $post_id );
  if ( $post_type !== $post_type_slug || $update ) {
    return;
  }

  update_post_meta( $post_id, 'wpcf-' . $field_slug, $forced_value );
}

// 1688213: Automatically select custom field value when order is created
add_action( 'save_post', 'tssupp_set_select_value_1', 100, 3);

Let me know if you have questions about this.
