If error in form

[blr32]

I have a system where people can input stuff into a form which then is sent to a database.

Naturally there is extensive errorchecking on the input so that when eg. a field is missing an errorpage will be included showing a descriptive error.

When the user has read the error he would normally be able to press the BACK button of his browser to be returned to the form with the form-values he already entered (except the password fields), but for some reason this script looses the form values.

Howcome is that? - I'm using hidden fields which are filled in servertime can that be it?

for form verification, i usually do this:
have the form's ACTION be itself. Then, at the top of the page, in the PHP code, you handle the form's data. if it all checks out, then go to the next page. if it doesnt, like there's an error or something, just fall through and show the page & FORM again. then, in the input elements, do this:

input type=text name='mooMoo' value="<?=htmlspecialchars($HTTP_POST_VARS['mooMoo'])?>"

and it does the trick every time.

lemme know if this works out for ya
