Help with an Amazon script, I'm new to all this!!!!

aircar · October 9, 2009

This is the code I'm using to mine Amazon.com for books to compliment the theme (keyword) of my site. I do not have a strong (???) understanding of php, and this script was purchased online for a couple of dollar (literally $1.85), but came with no support. I have not been able to make it work, and do not know how to effectively debug it. The file is Amazon.php

First off, Put the code in

tags. Err you can do that with {php} {/php} except change the "{}" to "[]".

Second off, this doesn't belong in php coding help. This belongs in "PHP applications".

Third off, if you buy something for 1.85$, don't expect something great.
