Question

他是谁，有谁知道如何解决这个问题？ php没有看到所选数据，并在按下submitButton

后给出错误信息是空的

我的代码：

<?php
session_start();
require_once '../connections/dbc.php';
$product_name = mysqli_real_escape_string($conn, $_POST['product_name']);
if (isset($_POST['submitButton'])) {
    if (!empty($_POST['product_name'])) {
        $sql=" INSERT INTO `order`(`product_name`) VALUES('$product_name');";
        $result = mysqli_query($conn, $sql);
        if (!$result) {
            echo "ERROR INSERTING THE ORDER IN THE DATABASE";
        }
    }   else{
        echo "EMPTY";
    }
}
?>
<!DOCTYPE html>
<html>
<head>
<title>TEST SITE</title>
</head>
<body>
   <form method="POST">
      <select>
         <option disabled="disabled" selected="selected" style="text-align: center;">--SELECT--</option>
<?php
    require_once '../connections/dbc.php';
    $query = "SELECT `product_name` FROM `product`";
    $response = @mysqli_query($conn, $query);
    if (!$response) {
        echo "NO RESPONES";
    }   else{
        while($row = mysqli_fetch_array($response)){
            echo '<option name="product_name" value="'.$row['product_name'].'" >'.$row['product_name'].'</option>';
        }
    }
?>
</select>
<button name="submitButton" id="submitButton"></button>
</form>
</body>
</html>

无法将数据从selectbox写入数据库，（＆＃34;空数据＆＃34;）
