PS: Ben geen wandelende debugger en dit had je zelf ook kunnen bedenken
En zet even bovin je index :
error_reporting(E_ALL) ;
Notice: Undefined index: start in D:\wamped\www\Webshop\include\class.inc.php on line 8
Notice: Undefined variable: PHP_SELF in D:\wamped\www\Webshop\include\class.inc.php on line 47
Notice: Undefined variable: PHP_SELF in D:\wamped\www\Webshop\include\class.inc.php on line 50
Notice: Undefined variable: PHP_SELF in D:\wamped\www\Webshop\include\class.inc.php on line 57
Maar zoals je ziet werkt het nu gewoon als je op de 2 klikt. Verder voor de meeste van die notices kan ik je doorverwijzen naar :
Simpele Vragen, Simpele antwoorden
Alles wat je naar het lezen van deze tut niet weg krijgt zal ik naar kijken en uitleggen (als het echt neit in de tut staat)
Hoop dat je iets aan mijn reactie hebt
Groetjes en Programmeerze,
Jacco

Zal eerst even naar je errors/notices kijken. Nette code is een must voor debuggen
en ja ik moet idd netter coderen.

Je nieuwe , e_all valid, class (volgens mij e_all valid altans :P)
PS: Netjes is weer een ander verhaal maar als jij er zo mee kan werken dan prima :)
PS : PS : ETRNAL GRATITUDE WILL BE MINE :P

Let btw niet op template :P net ff geintegreerd. Maar waarom doet ie ut niet vraag ik me af. sinds in tpl gebruik doetie ut niet meer.
Stoomcursus debuggen :
1. Wat moet het script doen
2. Tot waar doet hij wat hij moet doen :)
Ofterwijl : ga stap voor stap na wat er moet gebeuren. Echo de output om te kijken wat hij moet zijn.
Is dit niet het geval : Fout zit er voor
Is dit wel het geval : Fout zit er na
PS: This is as far as i go. Ik wil het best volledig voor je debuggen voor 15 euro. Dan ga ik niet uitbreiden alleen debuggen. Maar daar moet je me dan maar voor PM-en :)
Verdien je lekker geld mee :P maar als ik de paginanummer laat echoen in de php zie je ze (bovenaan) Maar als ik ze naar tpl omzet dan gaat ie neit werken :(
