The problem is because it's another web site who is using this data too. I can't make an "insert" into their database. Here is the process :
The user fill the form -> the data is sent to a page in my site and i'm processing the data -> i'm resending the data to another third party web site wich is aslo processing the data
That's what i want to do. And i really don't know how, except maybe in javascript who would refille a form and repost the form on the tag onLoad. But the user will see a "flash" of the page and it will be kind of strange.. Anyway, if you have any idea how to make that in php... 🙂
