我有一个表单，其中一个字段具有预定义的值(使用 php echo(。我正在尝试保存表单，以便所有值都存储在数据库中。
但是，预定义的值显示空白值，因此无法保存。
我收到错误消息，内容为：
未定义的索引用户标识
和
SQLSTATE[23000]：完整性约束冲突：1048 列"vd_user_id"不能为空
法典：
<?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'];

对于用户 id 标签，您使用了关键字 disabled 。禁用的输入永远不会发布。
因此，要么删除disabled，要么直接在代码中访问$userid。似乎$userid之后可以访问： if(isset($_POST['submit']) && isset($_POST["submit"])=="Save") {
要使输入保存到 post，您可以执行 JavaScript，也可以只执行一个隐藏值，并在后面加上echo，类似于：
<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>
