我有一個JQModal警報，需要首次訪問客戶端站點時纔會出現，但是當從站點內再次訪問索引頁時不會再顯示。如果可能的話，我在設置會話cookie方面並不真正，所以我需要一些明確的幫助。我已經創建了一個簡短的頁面，用它來測試：URL是http://www.caycecookbook.com/pop_ups/jqm_onDocReady/code.php。我在這裏附上代碼。需要關於會話腳本的幫助，僅顯示JQModal彈出窗口一次
<?php session_start();
if($_SESSION['visited']){
//don't show the modal box
} else {
$_SESSION['visited'] = true;
//show modal box;
}
?>
