Hi @bgrrota

I hope you are doing well, can you please create a ticket in WordPress.org > Forminator and we can verify it for you? I tested the code once again it still working, same for @whynotadv, kindly follow up from wordpress.org where we have more agents working.

Hello @patrickfreitasdev, I'm looking to achive
-> dynamically fill a select field values
-> set one of the values as default, depending on the page/post viewed

I'm using the code above and it works almost as expected. The only problem I have is, that I want to set one of the options as default, depending on which post the form is displayed. I tried

$post_id = get_queried_object_id(); // = the currently viewed page/post id
foreach ($posts as $post) {
    $new_options[] = array(
    'label' => $post->post_title,
     'value' => $post->post_title,
    'limit' => '',
    'default' => ($post->ID == $post_id) ? true : false,
    'key'   => forminator_unique_key(),
);
$opt_data['options'] = $new_options;
}

but this doesnt work. Any idea on how to achive this?
Thanks, Adam
