晚上所有,只是想弄清楚爲什麼我的一些變量沒有從我的MYSQL數據庫回顯。起初,他們都將是會話變量,而我發現沒有工作,於是我改成一個MySQL查詢我的發票頁上面PHP變量沒有迴應
$OrderID = $_SESSION[OrderID];
$LName = mysql_result(mysql_query("SELECT LName FROM customers WHERE Username = '$Username'"), 0);
$Fname = mysql_result(mysql_query("SELECT FName FROM customers WHERE Username = '$Username'"), 0);
$Date = mysql_result(mysql_query("SELECT Date FROM orders WHERE OrderID = '$OrderID'"), 0);
我的查詢。訂單ID和日期正在工作,但Lname和Fname不是所有內容都正確命名的地方,因爲它們在數據庫中。
下面的完整代碼,我試圖迴應他們。
