WPForms conditional form redirects

functions.php

<?php
/**
 * WPForms custom redirect
 *
 * @param string $url URL form will redirect to
 * @param int $form_id Form ID
 * @param array $fields Submitted form fields
 * @return string
 */
function wpf_custom_redirect( $url, $form_id, $fields ) {
	
	// Only consider changing the redirect if its for form #50
	if ( '50' == $form_id ) {

		// In the example below, we look at the submitted value for field #5
		// If that value is "test", then we change the redirect URL
		if ( !empty( $field['5']['value'] ) && 'test' == $field['5']['value'] ) {
			$url = 'https://wpforms.com';
		}
	}

	return $url;
}
add_filter( 'wpforms_process_redirect_url', 'wpf_custom_redirect', 10, 3 );

In order for this function to work, one must set desired WPForms confirmation type to "Redirect". I hope I could help someone. Regards
