Contact Form 7 AJAX Callback

Been searching around on this for a while and can't come up with any documentation to outline what i want to achieve.

I'm using wordpress and the Contact Form 7 plugin, all is working perfectly, what i want to achieve is to run some particular javascript upon form submit, i know we can use "on_sent_ok:" in the additional settings, but this only performs if the form is actually submitted.

What i'd like to do is to do some other javascript when the form doesn't submit ok, which throws the user back to the section which didn't validate.

I can use the following code to run after 1.7s of the form submit being clicked, however it's a bit sloppy as if the user was running with a slow connection, there's potential this could run before the form is submitted properly.

 $('.wpcf7-submit').click(function() {
setTimeout(function() {
    if ($('.fs1 input,.fs1 textarea').hasClass('wpcf7-not-valid')) {
        $('.pop-up-form').removeClass('pustep2').removeClass('pu-closing');
        $('.form-step').hide();
        $('.fs1').show();

    }
    if ($('.fs2 *').hasClass('wpcf7-not-valid')) {
        alert('error on page 2 - take user back to the area with issues')
    }
}, 1700);
});

Is there any particular function or hook i can use to run JS when the form AJAX has completed?

Thanks!

Solution 1:

In version 3.3 new jQuery custom event triggers were introduced:

New: Introduce 5 new jQuery custom event triggers

• wpcf7:invalid
• wpcf7:spam
• wpcf7:mailsent
• wpcf7:mailfailed
• wpcf7:submit

You can use wpcf7:invalid like the example below:

$(".wpcf7").on('wpcf7:invalid', function(event){
  // Your code here
});

Solution 2:

Given the variety of responses on this topic the plugin developer seems to change their mind about how this should work every 5 minutes. Currently (Q1 2017) this is the working method:

document.addEventListener( 'wpcf7mailsent', function( event ) {
  alert( "Fire!" );
}, false );

And the valid events are:

• wpcf7invalid — Fires when an Ajax form submission has completed successfully, but mail hasn’t been sent because there are fields with invalid input.
• wpcf7spam — Fires when an Ajax form submission has completed successfully, but mail hasn’t been sent because a possible spam activity has been detected.
• wpcf7mailsent — Fires when an Ajax form submission has completed successfully, and mail has been sent.
• wpcf7mailfailed — Fires when an Ajax form submission has completed successfully, but it has failed in sending mail.
• wpcf7submit — Fires when an Ajax form submission has completed successfully, regardless of other incidents.

Solution 3:

Sometimes it may not work, as Martin Klasson pointed out, only 'submit' event works, most probable because it's triggered by a form and bubbles up to the selected object. Also as I can understand, now events have other names, like "invalid.wpcf7", "mailsent.wpcf7", etc. In short, this should work:

jQuery('.wpcf7').on('invalid.wpcf7', function(e) {
    // your code here
});
