Question

我创建了一个包含一些数据的数据库。我已经能够使用Jquery Mobile显示数据。唯一的问题是，当我来到我的编辑页面，更新数据，并返回主页时，网址保持不变。例如：

我在example.com/index.php ---＆gt;点击指向example.com/index.php?id=1（或任何其他数字）的链接 - ＆gt;更新数据并单击以返回带有更新数据的index.php，但url保留在example.com/index.php?id=1，其内容为index.php。我糊涂了！！这是我的2个文件：

的index.php

  <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
  <meta name="viewport" content="width=device-width, initial-scale=1"> 
  <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />

任何人都可以提供帮助吗？

Answer 1

您收到一个未定义的错误，这意味着某些变量尚未设置。

问题在于输入字段。名称未设定。

     <input type="text" name="name" id="name" value="<?php echo $thuisscore; ?>"  />
     </div>

     <div data-role="fieldcontain">
     <label for="name"><b>Uitteam:</b></label>
     <input type="text" name="name" id="name" value="<?php echo $uitscore; ?>"  />

请注意，它们都具有相同的名称“name =”name“'，您稍后会将这些称为POST变量：

$thuisscore = mysql_real_escape_string(htmlspecialchars($_POST['thuisscore']));

$ uitscore = mysql_real_escape_string（htmlspecialchars（$ _ POST ['uitscore']））;

但它们不存在。

所以试试这个。

<input type="text" name="thuisscore" id="name" value="<?php echo $thuisscore; ?>"  />
     </div>

     <div data-role="fieldcontain">
     <label for="name"><b>Uitteam:</b></label>
     <input type="text" name="uitscore" id="name" value="<?php echo $uitscore; ?>"  />

同样在页面顶部初始化$ error变量（$ error = null;）

请记住将重定向更改为view.php而不是index.php

header('Location: index.php'); // becomes header('Location: view.php');

使用Jquery Mobile / PHP编辑数据无法正常工作
