ClickBank Valid Function for PHP
Are you trying to do Proof of Purchase Validation for ClickBank transactions?
We have your solution! PHP does not have the proper tools to accomplish this task easily.
We have laboured for hours to convert the scripts that ClickBank provides in Perl and C into PHP.
PHPValid is the fruits of our labour and we are now offering it to you. You can have this function in less than 5 minutes!
To give you an idea of how difficult it is, PHPValid has 10 times the amount of code in the Perl and C versions.
We have spent over 24 man hours in developing this replacement valid function for ClickBank users! At $30.00/hr thats $720.00 to
try to do this yourself!
Why is it so difficult?
The cgi purchase validation ClickBank uses needs unsigned integers to calculate the cbpop. PHP does not have this data type in its toolset.
PHP also does not have the proper bit shifting mechanisms needed to perform the bitwise manipulations neccessary. This means that in order to make PHPValid,
we had to return to the fundamental basics of binary manipulations. But you don't need to!!
How easy is it to use?
Very simple
<?php
include("PHPValid.php");
if(PHPValid($seed,$cbpop,$secretcode)) {
print "you verified";
}
else {
print "cannot verify";
}
?>
and have this function in less than 5 minutes!
The code is on our thank you page for you to have for only $29.95 US.
Example purchase and thank you pages included!
We will even provide you with fully commented example purchase and thank you pages!
We'll show you how to generate and use a random "seed" value on your purchase page. All you need to do is setup your ClickBank links.
Our example thank you script logs cbreceipts and verifys that the transaction hasn't been recorded already and prevents bookmarking.
and get set up in minutes with PHPValid and our examples!
