Sending to url in form behavior, problem with ampersand

Hi @jamminjames

I hope you are doing well today.

It seems in previous case we were able to provide some solutions to support ampersand in a hidden field. I pinged our SLS Team to review this new query and see how complex this will be. We will post an update here as soon as more information is available.

Kind Regards,
Kris

I think we might be able to hook in using the forminator_custom_form_submit_before_set_fields hook, correct? However, how would we test the result? How can we see what happens before the user is sent to the url?

I have not had much luck with the forminator_custom_form_submit_before_set_fields action. Everything I try results in a form submission error. I’ve tried things like this:

function my_submit_before_set_fields( $entry, $form_id, $form_data_array ) {
if ($form_id == 38164) {
$instanturl = str_replace('&', '&', $form_data_array['hidden-1']['value']);
$form_data_array = array_replace($form_data_array, $instanturl);
}
}
add_action('forminator_custom_form_submit_before_set_fields', 'my_submit_before_set_fields', 10, 3);

By the way, since the “behavior” provided is “Redirect user to a URL”, it seems like this sort of thing should be built in as a filter… before redirecting, Forminator ought to make sure any such introduced mistakes like “&” are replaced with the proper characters.

Hi @jamminjames,

This snippet should have worked in your use case:

<?php

add_filter( 'forminator_form_submit_response', 'wpmudev_fix_response_url_redirect', 20, 2 );
add_filter( 'forminator_form_ajax_submit_response', 'wpmudev_fix_response_url_redirect', 20, 2 );
function wpmudev_fix_response_url_redirect( $response, $form_id ) {
	if ( $form_id != 6 ) {
		return $response;
	}

	if ( ! empty( $response['url'] ) ) {
        $response['url'] = urldecode($response['url']);
        $response['url'] = str_replace('&amp;', '&', $response['url']);
	}

	return $response;
}

Could you please confirm by adding the above code as a mu-plugins and see whether it works?

You’ll need to update the following line with your form ID, suppose the form ID is 123, then the following line will change from:
if ( $form_id != 6 ) {

To:
if ( $form_id != 123 ) {

Please do let us know how that goes.

Kind Regards,

That works, thank you very much. Just for future reference, how could I see the result of $response or echo other things within the function for testing purposes?

Hi @jamminjames,

You can use the error_log in your code to display the value of the variables, for example, add this line before returning the $response :

error_log('Response: ' . print_r($response, true));

Please do note that you’ll need to have debug mode enabled and these values will be logged in the debug.log file.

Please check the following doc for more info:
