When you enter "on_sent_ok" hook to redirect to a custom url after submitting the form successfully in the Contact Form 7 plugin for WordPress, the following error message will appear: 1 configuration error detected in this tab panel.
Please note that the method using on_sent_ok hook is no longer recommended in order to redirect to another URL; this function is scheduled to be abolished by the end of 2017.
Instead, you can embed the following script into your theme’s template file:
<script>
document.addEventListener( 'wpcf7mailsent', function( event ) {
location = 'http://example.com/';
}, false );
</script>You know, Contact Form 7 provides several types of custom DOM events. You can utilize the events within your JavaScript code to run a function in a specific situation. Please visit this page for more information on Contact Form 7’s custom DOM event.
It's easy to specify a custom url to which users will be redirected after submissions when using Quform.
