Hello,
We have a client using gravity forms with an HTML block element to dynamically draw an HTML 5 Canvas element for capturing handwritten signatures. We need to post this to our 3rd party servers and have setup gform_after_submission so that it works properly.
The issue is that the signature capture element has 3 different hidden fields, and it appears that the hook requires you use the overall field ID (i.e. that of the HTML block itself) to post it through. We've tried using the specific hidden field names, e.g. 'signature' => $entry["signature"] to no avail.
Any help/insight would be greatly appreciated.
Thanks!
