Custom Smart Tags with ACF Field not displaying

Hello there,

I am using both PRO version for ACF and WP Forms, and followed the guide from: https://wpforms.com/developers/how-to-create-a-smart-tag-from-an-acf-field/

However, it’s either just displaying my custom smart tag, which is {listing_room_name}, as it is or it’s just not displaying at all.

I have created the following:

/* Smart Tags for WP Forms */
/**
 * Register the Smart Tag so it will be available to select in the form builder.
 *
 * @link   https://wpforms.com/developers/how-to-create-a-smart-tag-from-an-acf-field/
 */
 
function wpf_dev_register_smarttag( $tags ) {
  
    // Key is the tag, item is the tag name.
    $tags[ 'listing_room_name' ] = 'Listing Room Name';
  
    return $tags;
}
 
add_filter( 'wpforms_smart_tags', 'wpf_dev_register_smarttag' );
  
/**
 * Process the Smart Tag.
 *
 * @link   https://wpforms.com/developers/how-to-create-a-smart-tag-from-an-acf-field/
 */
 
function wpf_dev_process_smarttag( $content, $tag ) {
  
    // Only run if it is our desired tag.
    if ( 'listing_room_name' === $tag ) {
 
        //Get the field name from ACF
        $my_acf_field = get_field( 'listing_room_name', get_the_ID() );
 
        // Replace the tag with our link.
        $content = str_replace( '{listing_room_name}', $my_acf_field, $content );
    }
  
    return $content;
}
 
add_filter( 'wpforms_smart_tag_process', 'wpf_dev_process_smarttag', 10, 2 );

I wanted to display the Listing Room Name which was a text field from ACF.

So that visitors who submit the form know what they’re inquiring for.

Am I missing anything based on the guide?

Thanks.
