当您从 html 表单中选择单选按钮时，我可以指定您希望运行的 php 代码块吗？

例如，我有许多用户可以填写的字段，但我希望 PHP 代码根据他们选择的单选按钮输出不同的内容。

 <html>
<body>

<form action="citation.php" method="post">
<table width="100%" border="0">
  <tr>
    <td>Name</td>
    <td><label for="name2"></label>
      <input type="text" name="name" id="name2"></td>
  </tr>
  <tr>
    <td>Number</td>
    <td><label for="number"></label>
      <input type="text" name="number" id="number"></td>
  </tr>
  <tr>
    <td>Email</td>
    <td><label for="email"></label>
      <input type="text" name="email" id="email"></td>
  </tr>
  <tr>
    <td>Address</td>
    <td><label for="address"></label>
      <input type="text" name="address" id="address"></td>
  </tr>
  <tr>
    <td>web</td>
    <td><label for="web"></label>
      <input type="text" name="web" id="web"></td>
  </tr>
  <tr>
    <td><p>
      <label>
          <input type="radio" name="RadioGroup1" value="ex1" id="RadioGroup1_0">
          ex1</label>
        <br>
        <label>
          <input type="radio" name="RadioGroup1" value="ex2" id="RadioGroup1_1">
          ex2</label>
        <br>
        <label>
          <input type="radio" name="RadioGroup1" value="ex3" id="RadioGroup1_2">
          ex3</label>
        <br>
    </p></td>
    <td><input type="submit" name="click me" id="click me" value="Submit"></td>
  </tr>
</table>
<p>&nbsp;</p>
</form>
</body>
</html>

因此，如果他们选择第一个单选按钮并单击“提交”，则会输出与选择第二个单选按钮不同的内容。

For example, I have a number of fields a user could fill out but I want the PHP code to spit out something different depending on which radio button they select.

 <html>
<body>

<form action="citation.php" method="post">
<table width="100%" border="0">
  <tr>
    <td>Name</td>
    <td><label for="name2"></label>
      <input type="text" name="name" id="name2"></td>
  </tr>
  <tr>
    <td>Number</td>
    <td><label for="number"></label>
      <input type="text" name="number" id="number"></td>
  </tr>
  <tr>
    <td>Email</td>
    <td><label for="email"></label>
      <input type="text" name="email" id="email"></td>
  </tr>
  <tr>
    <td>Address</td>
    <td><label for="address"></label>
      <input type="text" name="address" id="address"></td>
  </tr>
  <tr>
    <td>web</td>
    <td><label for="web"></label>
      <input type="text" name="web" id="web"></td>
  </tr>
  <tr>
    <td><p>
      <label>
          <input type="radio" name="RadioGroup1" value="ex1" id="RadioGroup1_0">
          ex1</label>
        <br>
        <label>
          <input type="radio" name="RadioGroup1" value="ex2" id="RadioGroup1_1">
          ex2</label>
        <br>
        <label>
          <input type="radio" name="RadioGroup1" value="ex3" id="RadioGroup1_2">
          ex3</label>
        <br>
    </p></td>
    <td><input type="submit" name="click me" id="click me" value="Submit"></td>
  </tr>
</table>
<p> </p>
</form>
</body>
</html>

So, if they choose the first radio button and hit submit, that would spit out something different than if you chose the 2nd radio button.

这是非常基本的 PHP

<?php
  if($_POST['RadioGroup1']=='ex1'){
    ?>
     You hit the first radio button, now he's hurt!
    <?
  }elseif($_POST['RadioGroup1']=='ex2'){
     ?>
     You hurted the feelings of the second radio btn
     <?
  }elseif($_POST['RadioGroup1']=='ex3'){
    ?>
     The tird radio button was clicked by you
    <?
  }
?>

甚至更好：

<?php
  switch($_POST['RadioGroup1'){
     case 'ext1':
        ?>
         You hit the first radio button, now he's hurt!
       <? 
      break;
     case 'ext2':
        ?>
          You hurted the feelings of the second radio btn
       <? 
      break;
     case 'ext3':
        ?>
          The tird radio button was clicked by you
       <? 
      break;
        default: die('wrong')
    }
  }
?>

您还可以包含文件，而不是将 HTML 粘贴到 PHP 中：

<?php
  switch($_POST['RadioGroup1'){
     case 'ext1':
        include('form/1clicked.php')
      break;
      ....
    }
  }
?>

it's quite basic PHP

<?php
  if($_POST['RadioGroup1']=='ex1'){
    ?>
     You hit the first radio button, now he's hurt!
    <?
  }elseif($_POST['RadioGroup1']=='ex2'){
     ?>
     You hurted the feelings of the second radio btn
     <?
  }elseif($_POST['RadioGroup1']=='ex3'){
    ?>
     The tird radio button was clicked by you
    <?
  }
?>

or even nicer:

<?php
  switch($_POST['RadioGroup1'){
     case 'ext1':
        ?>
         You hit the first radio button, now he's hurt!
       <? 
      break;
     case 'ext2':
        ?>
          You hurted the feelings of the second radio btn
       <? 
      break;
     case 'ext3':
        ?>
          The tird radio button was clicked by you
       <? 
      break;
        default: die('wrong')
    }
  }
?>

instead of pasteing HTML in th the PHP, you could also include files:

<?php
  switch($_POST['RadioGroup1'){
     case 'ext1':
        include('form/1clicked.php')
      break;
      ....
    }
  }
?>

当您进行标准表单提交时，表单字段的 name 字段会自动作为 POST 参数传递给 php，即在 $_POST 中。如果字段具有 name="test" 和 value="valueTest"，那么在 php 层，您将获得该值 $_POST['test ']。以下是如何处理您的特定情况的示例：

    <?php

        switch ($_POST['RadioGroup1']) {
            case 'ex1':
                // handle ex1 case
                break;
            case 'ex2':
                // handle ex2 case
                break;
            case 'ex3':
                // handle ex3 case
                break;
            default:
                // handle cases here where RadioGroup1 has invalid value
                break;
        }

    ?>

When you do standard form submission, the name field of form fields automatically are passed to php as POST params, i.e., in $_POST. If a field has name="test" and value="valueTest", then at the php layer, you will get that value as $_POST['test']. Below is an example of how to handle your particular case:

    <?php

        switch ($_POST['RadioGroup1']) {
            case 'ex1':
                // handle ex1 case
                break;
            case 'ex2':
                // handle ex2 case
                break;
            case 'ex3':
                // handle ex3 case
                break;
            default:
                // handle cases here where RadioGroup1 has invalid value
                break;
        }

    ?>
