Sending a user back to their referring URL, on create & update

I needed a way to send the user back to the referring url when they both created and updated a form.

I initially used [server param="HTTP_REFERER"] in a field then used that field when selecting 'redirect to URL' in the form's settings. However I found that on updating a form this didn't change the field.

To get around this limitation I added the following script to the field's customise HTML box.

<script>
$(document).ready(function() {
var referrer = document.referrer;
$("#field_y919m").val(referrer);
$("#field_y919m").change();
});
</script>

Just change 'y919m' to the field key of the field you would like to have the referring url added.

Thought it might be good to share.
