我试着计算链接被点击的次数,然后重定向到具有该ID的联盟网站.我已经设法做了点击部分,每次点击链接时它在数据库中更新1但是有重定向部分的问题,我将id发送到track.PHP然后在那里检索id但我从那里重定向有问题.在数据库中我有affiliate_link并存储在那里的网址.任何帮助都会很棒.

在track.PHP上

<?PHP 
require_once $_SERVER['DOCUMENT_ROOT'].'/market/core/inIT.PHP'; 

//update count click in database
if(isset($_GET['id'])){
$id = is_numeric($_GET['id']);
$db->query("UPDATE credit_card_offers SET count_click = count_click + 1 WHERE id = '$id'");
header('Location: How_to_call_Affiliate_link_here_form_database?');
}
?>

在index.PHP上.
