Contact Form 7 - add custom function on email send

Question

Just playing around with Wordpress / Contact Form 7.

Is it possible to add custom javascript function on successful email send event?

Answer 1

Just a quick note that on_sent_ok is deprecated.

Contact form 7 is now using event listeners, like this;

<script type="text/javascript">
  document.addEventListener( 'wpcf7mailsent', function( event ) {
      if ( '11875' == event.detail.contactFormId ) { // if you want to identify the form
       // do something
      }
  }, true );
</script>

Then add this to the wp_footer action.

like this;

add_action( 'wp_footer', 'wp1568dd4_wpcf7_on_sent' );

function wp1568dd4_wpcf7_on_sent() { 
  // the script above
}

Answer 2

Contact Form 7 emits a number of Javascript events that bubble up to the document object. In version 4.1 they can be found in contact-form-7/includes/js/scripts.js. If you're using jQuery you can access those events like this:

$(document).on('spam.wpcf7', function () {
    console.log('submit.wpcf7 was triggered!');
});

$(document).on('invalid.wpcf7', function () {
    console.log('invalid.wpcf7 was triggered!');
});

$(document).on('mailsent.wpcf7', function () {
    console.log('mailsent.wpcf7 was triggered!');
});


$(document).on('mailfailed.wpcf7', function () {
    console.log('mailfailed.wpcf7 was triggered!');
});
