custom user meta in hidden fields?

Hi @hydevelop1994

I hope you’re well today!

You’re on a right track but, unfortunately, this code is a bit outdated. Since then there were multiple updates to the plugin and at some point due to security requirements there were changes made to how hidden fields are handled. There are now additionally validated and even if you change their values in page source (which is, essentially, what this code does), those values will be stripped and only the values originally set in hidden field configuration would be saved.

You’ll need a bit different code to handle that:

<?php 

add_action('forminator_custom_form_submit_before_set_fields', 'wpmudev_change_hidden_fields_data', 10, 3);
function wpmudev_change_hidden_fields_data($entry, $module_id, $field_data_array) {
    
	$form_ids = array(3010); //Please change the form ID
    
	
	if (!in_array($module_id, $form_ids)) {
        return;
    }
	
	if (!is_user_logged_in()) {
		return;
	}
	
	$user = wp_get_current_user();
	$user_data = get_userdata($user->ID);
	
	foreach ($field_data_array as $key => $value) {
		
		// HERE YOU MODIFY YOUR HIDDEN FIELDS VALUES
		
		# set user bio 
        if (strpos($value['value'], 'user_bio') !== false) {
            Forminator_CForm_Front_Action::$info['field_data_array'][$key]['value'] = $user_data->description;
        }
		
		
		
    }
}

Note: in page source you will not see any changes and actual user data; only in submission.

To “configure” the code

1. in this line

$form_ids = array(3010); //Please change the form ID

replace the 3010 number with your form ID; form ID is the number you see in form’s shortcode

2. this is the block that sets actual value of the field:

# set user bio 
        if (strpos($value['value'], 'user_bio') !== false) {
            Forminator_CForm_Front_Action::$info['field_data_array'][$key]['value'] = $user_data->description;
        }

It works based on the similar principle as in the code that you already tried so I believe you got the idea. To set other fields, you just need to repeat that block and adjust field name and the data you assign to it.

If you also need those hidden fields to be reflected in e-mail notifications (not only DB saved submissions) you may need to add another piece of code to the same MU plugin file:

add_filter('forminator_prepared_data', 'wpmudev_update_hidden_field_val_copy', 10, 2);
function wpmudev_update_hidden_field_val_copy($prepared_data, $module_object)
{
    $form_ids = array(3010); //Please change the form ID
    if (!in_array($module_object->id, $form_ids)) {
        return $prepared_data;
    }
 
    foreach ($prepared_data as $key => $value) {
        
		// repeat this block as many times as the number of hidden fields that you modified with code
		// note: here you don't use field values but actual hidden fields IDs
		// of hidden fields that you modified. 
		if (strpos($key, 'hidden-1') !== false) {
            $prepared_data[$key] = sanitize_text_field($_POST[$key]);
        }
		
		
    }
 
    return $prepared_data;
}

Again, in this line

$form_ids = array(3010); //Please change the form ID

you will need to replace number 3010 with the form ID (same as with other code above).

And this block of code

if (strpos($key, 'hidden-1') !== false) {
            $prepared_data[$key] = sanitize_text_field($_POST[$key]);
}

will need to be repeated as many times as the number of hidden fields that you modified with the other code. Note that here you – as in above example – you need to use hidden fields IDs; you need to use the same IDs as the IDs of the fields that are modified.

Kind regards,
