How to save CPT taxonomy name in entry table?

Hi
I am using Gravity Forms + Custom Post Types to create a custom post type. The category is saved as the taxonomy ID in the entry table:

GF is able to display as the category name in the notification emails:

I can use the merge tag: {Tree Campaign:7} in email notifications and it works fine:

But I need the entry table to store the Name and not the ID. I have tried adding other hidden fields, single line, paragraph, hidden etc to the form with the same merge tag: {Tree Campaign:7} – but nothing seems to work.

Can you help me save the category name in the entry table please? It is very important as I sync the table information with another email program and need the name not the ID.

I have contact GF support and they say I need to speak with you about this. They helped me develop this code to save the post category as a hidden field:

/*GF action for tree_campaign_name*/
add_action( 'gform_pre_submission_26', 'pre_submission' );
function pre_submission_handler( $form ) {

$cat_id = rgpost( 'input_7' );
$cat = get_term( $cat_id, 'category' );
$cat_name = ! is_wp_error( $cat ) && is_object( $cat ) ? $cat->name : '';
$_POST['input_19'] = $cat_name;

}

But this doesn’t work as it is not a standard post or category.

Any ideas on how to do this or adapt this code to work with the custom post types created by your plugin?

It’s for taxonomy=tree-campaigns&post_type=trees

thanks in advance for the help
