Post-map-repost Marketo Referral Form

Like Darshil says, please don’t use this code. Anything on jsFiddle is way outdated and all the latest snippets are on my CodePen.

In any case, the problem here is that you’re trying to submit the form (the second submit, on behalf of the referral) with required fields empty. That won’t work, so it fails silently.

Well, you're missing setting the '_mkt_trk' to null during the 2nd form post in the onSuccess method (and a separate form for the person being referred won't be submitted).

See my comments in the script below!

<script src="/js/forms2/js/forms2.min.js"></script> 
<form id="mktoForm_1347" style="max-width:100%;"></form>

<script>
  MktoForms2.loadForm("/", "720-FTJ-659", 1347);

  MktoForms2.whenReady(function(form) {
    var originalValues;

    form.onSubmit(function(form) {
      originalValues = form.getValues(); // stores original values in variable
    })

    form.onSuccess(function(vals, thankYouURL) {
      this.onSuccess(); // clear onSuccess for 2nd run

      this.setValues({
        'FirstName': originalValues['referralFirstName'],
        'LastName': originalValues['referralLastName'],
        'Email': originalValues['referralEmail'],
        'Company': originalValues['referralCompanyName'],
        'referralFirstName': '', // These fields are required on the form but have no values assigned
        'referralLastName': '',
        'referralEmail': '',
        'referralCompanyName': '',
        'referralPhoneNumber': '',
        '_mkt_trk': '' //Clearing cookies before form-submit is critical for the referrer form setup
      }); // remaps values for second submit

      this.submit(); // submits it again
    }.bind(form));

  });
</script>

Also, I'd recommend using Sandy's newer and improved MktoForms2 :: Referral v2.0.2 script instead of this older version.
