Hi, I have a multi page form with Page 1 having a file upload field. Now once the user moves to the next page, the file gets uploaded and I would like to process the file through a hook and populate fields on page 2 from the processing results.
I can see hooks being fired:
1) gform_validation: however, I don't to be able to set the field value here on the $form
2) gform_post_paging: this one does not allow me to return anything to modify the value of a field on the second page too.
Your advice would be greatly appreciated.
Oliver.
