the post info might contain some very long strings, (including essays and long documents). GET query strings aren't an option for me because of the length of the strings and because they might contain special characters (althought i guess i could use urlencode() for this). session variables might be an option for me since they can contain a bit more info than a url can, but i with all of the fields i am using across multiple forms, it would get messy.
i already made a nice little array walker, and i am now just looking for a way to pass the POST array from one page to another and back again if the info is incorrect.
i have tried using hidden form fields, but the problem is they don't work when the browser is sent back to the previous page. I want to be able to send the user back to the form if they enter incorrect info. i want to put all the info back into the fields, and leave them a note telling them which fields are wrong (so using the javascript goback() function won't work either).
