| * There are a couple of places where we use GravityForms to do a file upload into a | |
| * meta-data item of type "upload". The upload file type stores an attachment ID, | |
| * whereas the Gravity Forms upload field stores a URL. | |
| * | |
| * This function is used to convert a URL in the meta-data item specified by the | |
| * $field parameter to an attachment ID - creating the attachment as it goes. | |
| * | |
| * This function should be called from a callback hooked to gform_after_submission_[x] | |
| * | |
| * This is based on the code here: http://www.pastie.org/3167687 | |
| * which was submitted to this support thread: http://www.gravityhelp.com/forums/topic/file-upload-as-attachment-id | |

How to get the attachment id of an image that was uploaded using the 'Post Image' post field in gravity forms?
I'm trying to add a post from the front end using wp_insert_post, I need an attachment id to pass it to update_post_meta. Is this possible?

This looks like exactly what I need, though I'm struggling to implement. Could I be so bold as to ask for your help?
