This class will display a random product from your CafePress store. You can supply a simple template to control style, and have the output link directly to the shown product or simply to your main account. You can cache the results so you don't have to connect to the CafePress website all the time. Images can also be cached locally, and can be resized before caching.

// Description
//
// This class will display a random product from your CafePress store.
// You can supply a simple template to control style, and have the
// output link directly to the shown product or simply to your main
// account. You can cache the results so you don't have to connect to
// the CafePress website all the time. Images can be cached and work
// on the same time length as the product list caching. Images can
// also be resized as desired before saved into the cache.
//
// This has only been tested with the free accounts from CafePress,
// and requires PHP 4.1.0+

// Example of use
//
// $cp = new cafePressBox('collingtons');
// $cp->setCacheDir('./cache');
// $cp->setCacheTime(86400);
// $cp->setCacheImages(true);
// $cp->displayItem(true);
//
// With a REALLY simple template
//
// $cp = new cafePressBox('amnuts');
// $cp->setTemplate('<div align="center">[IMG]<br>[TXT]</div>');
// $cp->displayItem(false);
//
// [IMG] is where the product image will be displayed
// [TXT] is where the product text will be displayed
//
// Example with using a category with a paid-for account
//
// $cp = new cafePressBox('amnuts', '123456');
// $cp->displayItem(true);
//
