php - 在mysql中插入多个相同名称的字段

Question

请帮忙。我在论坛中找到了一些工作代码，但我认为它有问题。我的数据库中没有插入任何数据(描述和数量) 这是我的 php 代码:

<?php
$host = "localhost";
$username = "root";
$password = "";
$dbname = "posharrison";

mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$dbname")or die("cannot select DB");

$branch=$_POST['branch'];
$mydate=$_POST['mydate'];
$product=$_POST['product'];

$description = implode(',',$_POST['description']);
$quantity = implode(',',$_POST['quantity']);
$sql = "INSERT INTO orderlist (`description`,
`quantity`) VALUES ('".$description."', '".$quantity."')"; 

$sql = "INSERT INTO orderlist (branch, date, pname)
VALUES ('$branch', '$mydate', '$product')";
$result=mysql_query($sql);

if($result){
echo "<script>
        alert('Success');
        window.location ='./order.php';
        </script>";
}

else {
echo "ERROR!!".die(mysql_error());
}
?> 
<?php 
// close connection 
mysql_close();
?>

这是我的 html 代码:

<div class="desktop box" style="display:none">
                                    &nbsp;&nbsp;Select Item:

Answer 1

您将覆盖此行之前的查询:

$result=mysql_query($sql);

您应该运行这两个查询:

$sql = "INSERT INTO orderlist (`description`,
`quantity`) VALUES ('".$description."', '".$quantity."')"; 
 $result=mysql_query($sql);

$sql = "INSERT INTO orderlist (branch, date, pname)
VALUES ('$branch', '$mydate', '$product')";
$result=mysql_query($sql);
