無法使用PHP PDO在mysql DB中以表格形式保存值

Question

我有一種形式，其中一個字段具有預定義的值（使用php echo）。 我正在嘗試保存表單，以便所有值都存儲在DB中。

但是，預定義值顯示為空白值，因此無法保存。

我收到錯誤消息，內容為：

未定義的索引用戶ID

和

SQLSTATE [23000]：違反完整性約束：1048列“ vd_user_id”不能為空

碼：

<?php    
$email = $_SESSION['email'];
$STM = $conn ->prepare("SELECT * FROM vendorusers WHERE vd_user_email = :email");

$STM->bindParam(':email',$email);
$STM->execute();

$rows = $STM->fetchAll();

foreach ($rows as $row) {
$username = $row['vd_user_name'];
$userid = $row['vd_user_id'];
?>

Answer 1

對於userid標記，您使用了關鍵字disabled 。 禁用的輸入永遠不會過帳。

因此，請刪除已disabled或直接在代碼中訪問$userid 。 似乎$userid可在以下時間訪問： if(isset($_POST['submit']) && isset($_POST["submit"])=="Save") {

Answer 2

為了使輸入保存到發布中，您可以使用javascript或只做一個隱藏值，並在其后添加echo ，類似於：

<form name="userForm" role="form" action="" method="post" novalidate>
    <div class="form-group">
        <label>Restaurant Name</label>
        <input type="hidden" class="form-control"  id = "username" name = "username[]" value= "<?php echo $username; ?>" />
        <?php echo $username; ?>
    </div>
    <div class="form-group">
        <label>User ID </label>
        <input type="hidden" class="form-control"  id = "userid" name = "userid" value= "<?php echo $userid; ?>" />
        <?php echo $userid; ?>
        <?php  } ?>
    </div>
