Hi Ray
The reason is I want that when the user fill ok all the data fields but he put a wrong captcha he only need to re-write just the captcha code and not all data fields in my form

This is the solution
But that aside, the big-picture concept would be something like this:
1. Client submits form
2. Server copies form data to PHP session
3. Server validates form data
4. Whether or not server validation works, server reloads input value= attributes with data from session.
5. If validation is OK, server processes form data
6. if validation is not OK, server sends form data back to client with the prepopulated form.
