Upload file on treatment page
I would like to use the upload file on a treatment page and not from the form submit.
In fact, after submit, I go to a check page to verify all datas are correct.
If datas are correct, I then Insert into Mysql the datas and would like at that moment to rename and save the uploaded file on the server.
Is that possible and how ?
Thank you in advance for your help (and sorry if my english is not perfect, it is not my usual language).
