Passing form data on

[tomgone]

Hiya,

I have a form which is mostly validated through some JavaScripts, but I then pass all information on to a php script which does some final validation against a MySQL db (does the username already exist for example). If the username is unique, the record is added and all is well, but if the username exists, I build a page which asks the user to pick another name, and when they submit I call the same page again.

To pass all form data (basically to itself again) I use hidden fields now, is there a better way?

if you are using PHP4, sessions is good, more secure way of doing it. YOu can read a couple good articles on session in the columns area on this site.

Cheers for that. Need to get clued up on sessions anyways. My next task is to make sure people can not "hijack" a page in the middle of the site, i.e. go straight to a page and thus bypass the login. So I'm guessing sessions will do this for me, where each page need to check for a valid session id and if its not valid, then the page will not be shown?

Cheers
