ich versuche gerade die Shopping Card aus diesem Tutorial (http://www.qualitycodes.com/tutorial.php?articleid=25) in ein Modul zu packen.
Ich bin erst bei der Products-Seite und kommt nicht weiter - hoffe Ihr könnt mir helfen.
Die Testdaten die ich versuche auszulesen liegen in der sc_products
Code: Alles auswählen
INSERT INTO `sc_products` (`serial`, `name`, `description`, `price`, `picture`) VALUES
(1, 'View Sonic LCD', '19" View Sonic Black LCD, with 10 months warranty', 250, 'upload/shop/lcd.jpg'),
(2, 'IBM CDROM Drive', 'IBM CDROM Drive', 80, 'images/cdrom-drive.jpg'),
(3, 'Laptop Charger', 'Dell Laptop Charger with 6 months warranty', 50, 'upload/shop/charger.jpg'),
(4, 'Seagate Hard Drive', '80 GB Seagate Hard Drive in 10 months warranty', 40, 'upload/shop/hard-drive.jpg'),
(5, 'Atech Mouse', 'Black colored laser mouse. No warranty', 5, 'upload/shop/mouse.jpg'),
(6, 'Nokia 5800', 'Nokia 5800 XpressMusic is a mobile device with 3.2" widescreen display brings photos, video clips and web content to life', 299, 'upload/shop/mobile.jpg');
