无法更新查询

Question

我正在尝试更新查询并显示到下一页。这是我的代码，问题是我将收到一条警告消息＆＃34;无法修改标题信息 - 标题已经发送＆＃34;。请帮忙。

$id = (isset($_GET['id'])) ? $_GET['id'] : '';
$val = view_data($id);
if (empty($_POST) === false) {
    $title = $_POST["offered"];
    $description = $_POST["description"];
    $id = $_POST["id"];
    $update = update($title, $description, $id);
    if ($update) {
        header("location:hotel2_galery.php");
    }
}

HTML

<form action="hotel2_galery_edit.php" method="post" class="col-sm-4">
   <div class="form-group has-info">
      <input type="hidden" name="id" value="<?php echo $val->offer_id;?>">
      <label class="control-label" for="inputSuccess">Offer title
      </label>
      <input type="text" class="form-control" name="offered" id="offered" value="<?php echo $val->offers_name; ?>">
      <label>Offer Description
      </label>
      <textarea id="description" name="description" class="form-control " rows="3">
      <?php echo $val->offers_description; ?>
      </textarea>
      <br>  
      <button type="submit" class="btn btn-primary">
      <span>UPDATE
      </span>
      </button>
   </div>
</form>

Answer 1

尝试

echo "<script>location.href='hotel2_galery.php'</script>";

而不是

header("location:hotel2_galery.php");

这是一个临时修复。如果您向我们展示完整的代码，我们可能会为您提供进一步的帮助。
