interstitial page- saving post/get variables and sending them to next page

[nishantcm]

Hi,

I have page- form.php . It sends say- var1, var2 ... var n variables to interstitial.php . interstitial.php will show an advertisement and there will be a button to skip the ad. I want to send all variables then to post.php.

How do I do that? I thought of hidden variables but for every request the variables might change.

Can you guys help!

Thanks,
Nishant

You might create the querystring to send to post.php (they will be visible), or you can put them in a session (they won't be visible).
I don't think hidden variables (= a form) is the way to go, unless one always has to press the button to continue.

Creating a query string means- sending variables by GET method? Am I right! So if I send the variables by get method then I have to somehow send all the variables to the final page.

Suppose inter.php?var1=name&var2=place&var3=animal
then clicking on SKIP button must open final.php?var1=name&var2=place&var3=animal

How to do this?

If the variables always arrive to inter.php in the querystring, then you might use

$_SERVER['QUERY_STRING'] and paste it to final.php.

If they can also arrive by POST, then you'll have to loop through $_POST and create the querystring yourself.

Thanks! But is there a limit to the amount of data you can send through a querystring?

I don't know. I'm sure there is
If you have too much data to send, then you might want to think about using sessions.

Actually I am using this to make a facebook app. So I dont want to get into sessions thing. I am thinking of using this function to build hidden fields.

<?php
while (list($key,$value) = each($_POST)){
echo "Key: ".$key . "Value: ".$value."<br />";
}
?>

Completely OT, but for future reference:

The spec for URL length does not dictate a minimum or maximum URL length, but implementation varies by browser. On Windows: Opera supports ~4050 characters, IE 4.0+ supports exactly 2083 characters, Netscape 3 -> 4.78 support up to 8192 characters before causing errors on shut-down, and Netscape 6 supports ~2000 before causing errors on start-up.
