Small php problem

andrej13 · February 27, 2011

I have made a php cart : check it out on http://fhcs.be/cart-demo4/

My question is: when I order something by clicking on the "voeg toe" button, I'm redirected to the shopping cart. But I don't want to be redirected to the shopping cart, I want to stay on de menu list. What is an easy way to fix this? thanks people

$result1 = $db->query($sql);
$output1[] = '<ul>';

}
$output1[] = '</ul>';
echo join('',$output1);
