產品不會被添加到購物車

我正在致力於onlineshop.php應該顯示錶格的頁面，每個表格都有一個「添加到購物車按鈕」的產品。產品顯示，但問題是，我選擇的產品不會添加到購物車。我不知道這是否是查詢或代碼本身的問題。產品不會被添加到購物車

onlineshop.php：

<?php 
ini_set('display_errors',1); 
error_reporting(E_ALL); 
include('connection.php'); 

if (isSet($_POST['Pro_ID'], $_POST['Price'] , $_POST['Pro_Name'])) 
{ 
    $qry="INSERT INTO shopping_cart(Cart_Name,Pro_Name,Pro_ID,Price) VALUES ('dzfgtdfxdf','$_POST[Pro_Name]','$_POST[Pro_ID]' , '$_POST[Price]' ) ";     
    $qry = 'SELECT * FROM product' ; 
} 
else    
    $qry = 'SELECT * FROM product' ; 
    //Run QUERY 
    $result = mysql_query ($qry); 
?>

把else語句'{''}' – Gowri 2014-11-25 11:31:38

[**請不要在新代碼'mysql_ *'功能**]（HTTP：/ /bit.ly/phpmsql）。他們不再被維護[並且被正式棄用]（http://j.mp/XqV7Lp）。看到[**紅框**]（http://j.mp/Te9zIL）？學習[*準備的語句*]（http://j.mp/T9hLWi），並使用[PDO]（http://php.net/pdo）或[MySQLi]（http://php.net/ mysqli） - [這篇文章]（http://j.mp/QEx8IB）將幫助你決定哪個。 – 2014-11-25 11:31:46

INSERT INTO shopping_cart'查詢似乎沒有在任何地方執行。 – 2014-11-25 11:33:17

變化

if (isSet

到

如果（isset

卸下大寫字母和小寫

替換它

您似乎在撰寫INSERT查詢，但您不會運行它。使用函數mysql_query()將查詢發送到要執行的MySQL服務器。

看起來您在執行INSERT之前覆蓋了$ qry變量。

所以你永遠不會插入數據到表中，你只是選擇它。

在SELECT之前運行INSERT，它應該可以工作。

我把\t \t \t \t \t \t $ result = mysql_query（$ qry）; 插入後，但它仍然無法正常工作 – user3419062 2014-11-25 11:44:55

你是否也改變isSet isset像其他答案建議，你確定你正在發佈你正在尋找的所有適當的項目嗎？換句話說，你確定你確實在執行該代碼，還是隻是跳過並轉到其他地方？試穿 'echo「test」; exit（）;' 在INSERT語句之上，看它是否觸發。 – jdcookie 2014-11-25 11:48:17

你能解釋你的最後一點嗎？ \t \t \t is this line wrong：\t \t if（isset（$ _ POST ['Pro_ID']，$ _POST ['Price']，$ _POST ['Pro_Name']]）??我如何知道它是否執行？ – user3419062 2014-11-25 12:01:05

試試這個：在一個塊

<?php 
ini_set('display_errors',1); 
error_reporting(E_ALL); 
include('connection.php'); 

        if (isset($_POST['Pro_ID'], $_POST['Price'] , $_POST['Pro_Name'])) { 


        $qry="INSERT INTO shopping_cart(Cart_Name,Pro_Name,Pro_ID,Price) VALUES ('dzfgtdfxdf','$_POST[Pro_Name]','$_POST[Pro_ID]' , '$_POST[Price]' ) "; 

         // 1) Run your SQL 
         mysql_query($qry); 
        } 
        // Actually, You don't need ELSE block statement, because this lines of code repeats in IF block, and in ELSE block. 
         $qry = 'SELECT * FROM product' ; 
        //Run QUERY 
        $result = mysql_query ($qry); 



    ?>
