Question

我正在添加到购物车。一切都很顺利。但是当我试图将会话2d数组中的数据存储到数据库中时，它没有正确发生，即最后一个产品的id和qty仅被存储。

这是用于在数据库中存储数据的页面

<?php
session_start();
echo "<pre>";
$value=$_SESSION['cart'];
foreach ($_SESSION['cart'] as $item) {
   // echo 'p_id: ', $item['id'], '<br />';
   // echo 'p_size: ', $item['p_size'], '<br />';
    //echo 'p_qty: ', $item['qty'], '<br /><br />';
}
//print_r($value);
echo"done";
echo $address=$_GET['add']; 
 echo "<br>";
 echo $con=$_GET['cont']; 
 echo "<br>";
 echo $mail=$_GET['mail'];
 echo "<br>";
 echo $pay=$_GET['mode'];
 echo "<br>";
 echo $total=$_GET['total'];
 echo "<br>";

 //echo "".$_SESSION['cart'];
 //echo $total=$_SESSION['id'];
 //echo $total=$_GET['total'];
 $servername = "localhost";
$username = "root";
$password = "root";
$dbname = "admin1";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "connected successfully";
echo"<br>";

foreach ($_SESSION['cart'] as $value){
   // print_r($_SESSION);
//print_r($_SESSION['cart']);
    $sql="INSERT INTO orders(total,id,qty,address,cont,mail,mode) values ('".$total."','".$value['id']."','".$value['qty']."','".$address."','".$con."','".$mail."','".$pay."')";

 }
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
?>

你应该在foreach循环中添加$ conn-＆gt;查询（$ sql）。试试吧：

    <?php
    session_start();
    echo "<pre>";
    $value=$_SESSION['cart'];
    foreach ($_SESSION['cart'] as $item) {
       // echo 'p_id: ', $item['id'], '<br />';
       // echo 'p_size: ', $item['p_size'], '<br />';
        //echo 'p_qty: ', $item['qty'], '<br /><br />';
    }
    //print_r($value);
    echo"done";
    echo $address=$_GET['add']; 
     echo "<br>";
     echo $con=$_GET['cont']; 
     echo "<br>";
     echo $mail=$_GET['mail'];
     echo "<br>";
     echo $pay=$_GET['mode'];
     echo "<br>";
     echo $total=$_GET['total'];
     echo "<br>";

     //echo "".$_SESSION['cart'];
     //echo $total=$_SESSION['id'];
     //echo $total=$_GET['total'];
     $servername = "localhost";
    $username = "root";
    $password = "root";
    $dbname = "admin1";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 
    echo "connected successfully";
    echo"<br>";
    $success= false;
    foreach ($_SESSION['cart'] as $value){
       // print_r($_SESSION);
    //print_r($_SESSION['cart']);
        $sql="INSERT INTO orders(total,id,qty,address,cont,mail,mode) values ('".$total."','".$value['id']."','".$value['qty']."','".$address."','".$con."','".$mail."','".$pay."')";

         if ($conn->query($sql) === TRUE) {
             $success = true;
         } else {
             echo "Error: " . $sql . "<br>" . $conn->error;
             $success = false;
             break;
         }

     }

    if($success) 
    echo "New record created successfully";

?>
