You can access all the form variables using the global $HTTP_POST_VARS array.

Example:

while(list($key,$val) = each($HTTP_POST_VARS)) {
print "$key => $val<br>";
}

The $key would be the name of the form-field and $val would be the value of that field.

How can I pass these variables as a form. I just want to know after filling the form by the user if anyfield contain invalid data how to return the form to the user with invalid data highlighted and valid data unchanged so that the user can recrrect the data and sumit again.
Thank you.
