Hi there,
I am trying to redirect a user back to a html form if a validation
failes. The form shoult then hold all entered values. So far I did this
over $_GET, but there is a 100 Character limitation. How could I do this
while keeping all characters?
Thank you for any hint,
Merlin

No need to POST and then redirect, just POST the form to itself. If
validation fails redisplay the form using the $_POST array.

Merlin:
Hint -- look at $_SESSION[]
Here's an example,
http://webbytedd.com/b1/simple-session/
Just enter "guest" and you'll see the code that makes it work. In
this case, it's just storing 1 in $_SESSIN['ok'], but you can have as
many session variables as you want.
Cheers,
tedd

This is not so easy. I am doing some checking with php on the values and
if one failes php returns via GET to the form with the help of header
location:
$parameter = "&demo=this";
HEADER("Location:/test.html?error=1".$parameter);
exit;
I would need to change way to many things in order to simply change to post.
Isn't there another way?

*Don't* use GET for this.
Here's the typical way this is done:
If the name of the file is myfile.php, then in the file do this:
--0-1805035061-1259160621=:3596
Content-Type: text/plain; charset=us-ascii
There are a couple of ways that you can do this:
1. Store the post values in the $_SESSION variable then echo them back to the screen. Be careful with this as it can lead to XSS. Strip html, etc
2. Send the post values back to the form as part of the query sting. This solution is limited to the size of the query string (2k). Be careful with XSS
Another solution is to use a framework to handle the post back values. One such framework is called Raxan. Here's an example of what it can do:

Hello Raymond,
thank you for your hint. I will go with sessions. Thanx for the note
regarding XSS.
Kind regards, merlin

This is what I normally do with larger forms:
1. create the form as a function: form()
2. submit the form to the same page
3. test relevant input and if the fail print form()
Example:
function form() {
print '
