Hi @stoodlee
I hope you are doing well.
You don’t need custom coding unless it is something more complex, but for hidden field, you can use the native option “Embed Post/Page Title – The title of the site page where the form is embedded.
https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#default-value
We do have a small bug, but to bypass the bug enable the load using Ajax on Form > Behaviour > Rendering > Ajax loading.
Let us know if it fits your needs.

Hi. Thanks for the quick response. I had used the native option “Embed Post/Page Title” for the Hidden Field.
But how do I then get that value into another input text field?
I want the field Textarea-2 pre-populated with the Post Title.
Here are screenshots of the form and fields:

Hi
By default, you can only pre-populate the post/page title into the HTML field by {embed_title} value. I asked our SLS Team if there is a way to fill textarea with page title. We will post an update here as soon as more information is available.
Kind Regards,
Kris
Hi again
Please:
add_action( 'forminator_before_form_render', 'wpmudev_post_data_form_check', 10, 5 );
function wpmudev_post_data_form_check( $id, $form_type, $post_id, $form_fields, $form_settings ) {
if ( 939 == $id ) { //Please change the form ID
add_filter( 'forminator_field_text_markup', 'wpmudev_add_post_page_title_text', 10, 2 );
}
}
function wpmudev_add_post_page_title_text( $html, $field ) {
if ( $field[ 'element_id' ] != 'textarea-2' ) {
return $html;
}
$post_id = get_the_ID();
$title = forminator_get_post_data( 'post_title', $post_id );
$html = str_replace('</textarea>', "$title</textarea>", $html);
return $html;
}
You will need to change 939 to your form ID and textarea-2 to your textarea field.
Kind Regards,
Kris
