Question

我正在尝试创建简单的表单和帖子。我创建了简单的表单。但提交后没有实际收到。我创建了单个form.php文件。

form.php的：

<!DOCTYPE html>
<html>
    <head>
        <title>Bootstrap 101 Template</title>
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <!-- Bootstrap -->
        <link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet" media="screen">
    </head>
    <body>

<div class="row">
<?php

echo 'Hello World';

foreach ($_POST as $key => $value) {
        echo "<tr>";
        echo "<td>";
        echo $key;
        echo "</td>";
        echo "<td>";
        echo $value;
        echo "</td>";
        echo "</tr>";
    }

?>
<div class="col-md-6 col-md-offset-3">
<form class="form-horizontal" action="form.php" method="post">
  <div class="form-group">
    <label for="input1" class="col-sm-2 control-label">Tag#1</label>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input1a" placeholder="Old Value" value="dummy">
    </div>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input1b" placeholder="New Value" value="dummy">
    </div>
  </div>
  <div class="form-group">
    <label for="input2" class="col-sm-2 control-label">Tag#2</label>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input2a" placeholder="Old Value" value="dummy">
    </div>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input2b" placeholder="New Value" value="dummy">
    </div>
  </div>
  <div class="form-group">
    <label for="input3" class="col-sm-2 control-label">Tag#3</label>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input3a" placeholder="Old Value" value="dummy">
    </div>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input3b" placeholder="New Value" value="dummy">
    </div>
  </div>
  <div class="form-group">
    <label for="input4" class="col-sm-2 control-label">Tag#4</label>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input4a" placeholder="Old Value" value="dummy">
    </div>
    <div class="col-sm-5">
      <input type="text" class="form-control" id="input4b" placeholder="New Value" value="dummy">
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <button type="submit" class="btn btn-default">Submit</button>
    </div>
  </div>
</form>
</div>
</div>

        <script src="http://code.jquery.com/jquery.js"></script>
        <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
    </body>
</html>

环境： linux mint 16 PHP5

apache2正在运行并且“echo'Hello World';”在form.php中提供的效果很好。

Answer 1

输入需要名称，而不是id，否则$ _POST数组没有键。

Answer 2

如果没有输入的name属性，您将无法在$ _POST中获得任何内容，因为输入被名称识别。

我已经替换了你的名字，请用我的代码替换你的代码。你已经完成了

Answer 3

<div class="col-sm-5">
  <input type="text" class="form-control" name="input1a" id="input1a" placeholder="Old Value" value="dummy">
</div>

如上面的代码段所示，您需要在输入标记上设置名称属性，以便在向表单提交POST请求时传递数据。

HTML表单没有以PHP格式发送POST
