Losing a value

[Bradford_Lad]

Hi,

When a user clicks on a link built from a MySQl table the string looks like this...

http://www.someone.com/file.php3?key=xx

the page is then displayed. I have a form on this page which I use PHP to validate, when the user clicks submit the page is redisplayed with any errors but I lose the "key" value and the url looks like this...

http://www.someone.com/file.php3

this means that I cannot update my Db with the entered form values as I have lost the "key" value.

How do I retain or save the "key" value ?

Cheers
John

Put it as a hidden field on the form.
