活动表不起作用

Question

我需要有一个有效的客户表。

它有效但当我离开页面并返回页面时，它不会将自己设置为活动或正确。但当我离开页面并再次返回时，它会将自己设置为活动状态。

我做错了什么？

if (!isset($_COOKIE['ActiveLead'])) $_GET['ActiveLead'] = 0; 
else 
$tchecked = $_COOKIE['ActiveLead']; 
if ($tchecked == 1) {
$_GET['ActiveLead'] = 1;
$title="Active Leads"; 
} else {
$_GET['ActiveLead'] = 0; }

if (($_GET['ActiveLead'] == 1) || ($_COOKIE['ActiveLead'] == '1')) {
$t1v="checked"; 
setcookie("ActiveLead", 0, time()+60*60*24*365); 
} else {
$t1v=""; 
setcookie("ActiveLead", 1, time()+60*60*24*365);
}

$ActiveLead_frLeads = "%"; 
if (isset($_GET['ActiveLead'])) {
  $ActiveLead_frLeads = $_GET['ActiveLead']; 

SELECT * FROM Leads WHERE (Leads.LeadNo = %s) OR (Leads.Active >= %s) ORDER BY `Date` DESC"

我是否需要进行会话？
