Hello,

There isn’t a way to add a captcha into the form however by modifying the plugin it’s possible to add a simple math verification form.

If you’d like to go this way, let me know and I’ll provide you the instructions.

Regards.

Yeah, I’ll do that. Please teach me how to do that. Thank you.

Ok, so to add a new field to the booking form you can use the built-in filter. You can add this code at the bottom of your theme’s functions.php file.

function wprm_custom_captcha( $booking_fields ) {
// Add the new field to the booking form
$booking_fields[] = array(
'type' => 'text',
'label' => '2+2 = ?',
'name' => 'wprm_math',
'placeholder' => '',
'value' => '',
'required' => true
);

return $booking_fields;
}
add_filter('wprm_booking_form_fields', 'wprm_custom_captcha' );

You should now see a new field into the form.

Now we need to tell the form what should do with that field. Unfortunately as of yet, there isn’t a filter to adjust the validation process of the form so we’ll have to edit the plugin manually.

Open file includes/class-wprm-bookings.php of the plugin and locate line 341 which should be empty. And add this code

if (isset($_POST['wprm_math']) && $_POST['wprm_math'] !== '4' ) {
$errors->add( 'cheater2', __('Are you trying to cheat?','wprm'));
}

It simply verifies whether the submitted value for that field is 4.

Regards.
