插入数据到mysql，只会插入第一个日期

所以，我有这个代码的小问题。它的工作正常，但如果我尝试插入两个（或更多...）数据，它的只是第一个数据将被插入。我该如何解决这个问题？插入数据到mysql，只会插入第一个日期

<?php 
    error_reporting(E_ERROR); 
    session_start(); 
    include("db_config.php"); 
    if(isset($_SESSION['login_user'])) 
    { 
    $username=$_SESSION['login_user']; 
    $sql[0] = "SELECT * from orders where username='$username'"; 
    $result= mysqli_query($conn,$sql[0]) or die(mysqli_error()); 

    if (mysqli_num_rows($result)>0) 
    { 
     while ($record = mysqli_fetch_array($result)) 
     { 
      $name =$record[username]; 
      $id = $record[id]; 
      $nmb_products = $record[nmb_products]; 
      $total_value = $record[total_value]; 
      $order_date = $record[order_date]; 
      $city = $record[dest_city]; 
      $address = $record[address]; 
     } 
    } 
    else echo "Failed Access"; 

    $sql[1] = "INSERT INTO ordered (username,nmb_products,product_id,total_value, city, address) VALUES ('$name', '$nmb_products', '$id', '$total_value', '$city', '$address')"; 
    $sql[2] = "DELETE FROM orders WHERE username='$username'"; 
    if(mysqli_query($conn, $sql[1]) && mysqli_query($conn, $sql[2])) 
    { 
     header("Location:mypurchases.php"); 
     exit(); 
    } 
    } 
    else 
    echo"Login first"; 

    $conn->close(); 
    ?>

你是什么意思“如果我尝试插入两个（或更多...）数据” –

举动'$ SQL [1]'内部while循环 –

我的意思是，我还有一个页面，而这页面有两个数据，只有第一个插入，另一个只是删除。 – Achy

所有这些部分：

$sql[1] = "INSERT INTO ordered (username,nmb_products,product_id,total_value, city, address) VALUES ('$name', '$nmb_products', '$id', '$total_value', '$city', '$address')"; 
$sql[2] = "DELETE FROM orders WHERE username='$username'"; 
if(mysqli_query($conn, $sql[1]) && mysqli_query($conn, $sql[2])) 
{ 
    header("Location:mypurchases.php"); 
    exit(); 
}

可能会在这个循环：

if (mysqli_num_rows($result)>0) 
{ 
    while ($record = mysqli_fetch_array($result)) 
    { 
     $name =$record[username]; 
     $id = $record[id]; 
     $nmb_products = $record[nmb_products]; 
     $total_value = $record[total_value]; 
     $order_date = $record[order_date]; 
     $city = $record[dest_city]; 
     $address = $record[address]; 
    } 
}

赞好：

if (mysqli_num_rows($result)>0) 
{ 
    while ($record = mysqli_fetch_array($result)) 
    { 
     $name =$record[username]; 
     $id = $record[id]; 
     $nmb_products = $record[nmb_products]; 
     $total_value = $record[total_value]; 
     $order_date = $record[order_date]; 
     $city = $record[dest_city]; 
     $address = $record[address]; 



     $sql[1] = "INSERT INTO ordered (username,nmb_products,product_id,total_value, city, address) VALUES ('$name', '$nmb_products', '$id', '$total_value', '$city', '$address')"; 
     $sql[2] = "DELETE FROM orders WHERE username='$username'"; 
     if(mysqli_query($conn, $sql[1]) && mysqli_query($conn, $sql[2])) 
     { 
      /*header("Location:mypurchases.php"); 
      exit();*/ 
      //Do something 
     } 
    } 
}

'header（）;退出（）;循环内肯定会有帮助。 –

是的。这是一个错误... 我的答案只是给出了使用的逻辑。 – Yvan

啊，谢谢:)现在工作 – Achy

试试这个，你必须把在查询所有DATAS：

if (mysqli_num_rows($result)>0) 
{ 
    $sql[1]=''; 
    while ($record = mysqli_fetch_array($result)) 
    { 
     $name =$record[username]; 
     $id = $record[id]; 
     $nmb_products = $record[nmb_products]; 
     $total_value = $record[total_value]; 
     $order_date = $record[order_date]; 
     $city = $record[dest_city]; 
     $address = $record[address]; 
     $sql[1].=" INSERT INTO ordered (username,nmb_products,product_id,total_value, city, address) VALUES ('$name', '$nmb_products', '$id', '$total_value', '$city', '$address');"; 
    } 
} 
else echo "Failed Access"; 


$sql[2] = "DELETE FROM orders WHERE username='$username'"; 
if(mysqli_multi_query($conn, $sql[1]) && mysqli_query($conn, $sql[2])) 
{ 
    header("Location:mypurchases.php"); 
    exit(); 
} 
}

使用mysqli_multi_query – JYoThI

插入数据到mysql，只会插入第一个日期
