Question

我正在页面上的php中创建一个表单＆＃34; index.php＆＃34;。加载页面时，将创建以下表单：

if($_SERVER['REQUEST_METHOD']!='POST')
{
        echo '
        <form action="index.php" method="POST">
        <fieldset style="width: 700px;">
        <legend>Enter your search below</legend>
        <textarea rows="1" cols="80" name="query">
        </textarea>
        </fieldset>
        <p>
        <input type="radio" value="Non-Aggregated"> Non-Aggregated
        <input type="radio" value="Aggregated"> Aggregated 
        &nbsp;
        &nbsp;
        <input type="submit" value="Search">
        </p>
        </form>';   
}

当用户点击提交按钮时，会显示相应的内容：

else
{
    if ($_POST['query'])
    {
        //content displayed after form submission
    }
}

返回表格，注意收音机选项：

<input type="radio" value="Non-Aggregated"> Non-Aggregated
<input type="radio" value="Aggregated"> Aggregated

根据 非聚合 或 聚合，我是否可以在if语句中执行不同的操作？从单选按钮中选择 ;如果是这样，我该怎么做呢？

感谢您提供任何帮助。

Answer 1

首先，为您的收音机指定一个“名称”。两者都一样。

<input type="radio" name="aggregation" value="Non-Aggregated"> Non-Aggregated
<input type="radio" name="aggregation" value="Aggregated"> Aggregated

在“else”条款中，进行一些小改动，

if($_SERVER['REQUEST_METHOD']!='POST')

使用

if($_SERVER['REQUEST_METHOD']=='POST')

最后，但并非最不重要的是，如果...

，请将你的条件添加到最后

if ($_POST['aggregation'] == 'Aggregated')
{
// Actions for Aggregated
}
else
{
// Actions for Non-Aggregated
}

Answer 2

将名称属性赋予单选按钮，例如

<input type="radio" name="aggr" value="Non-Aggregated"> Non-Aggregated
<input type="radio" name="aggr" value="Aggregated"> Aggregated

执行POST方法后，您可以使用PHP检查值：

if($_POST['aggr']=='Aggregated'){
//DO STUFF
}
if($_POST['aggr']=='Non-Aggregated'){
//DO OTHER STUFF
}

换句话说，您可以设置名称，例如

<input type="radio" name="Non-Aggregated" value="Non-Aggregated"> Non-Aggregated
<input type="radio" name="Aggregated" value="Aggregated"> Aggregated

如果isset

，请检查此项

if(isset($_POST['Aggregated'])){
    //DO STUFF
}
if(isset($_POST['Non-Aggregated'])){
  //DO OTHER STUFF
}

Answer 3

<?php
if($_SERVER['REQUEST_METHOD']!='POST')
{
    // echo the form and don't forget to give the radio inputs a name
    // <input name="agg" type="radio" value="Non-Aggregated"> Non-Aggregated
    // <input name="agg" type="radio" value="Aggregated"> Aggregated 
}
else if (isset($_POST['agg']))
{
    if ($_POST['agg'] == 'Aggregated') {
        // do one thing
    } else {
        // do something else
    }
}

Answer 4

这是工作代码：

<?php if($_SERVER['REQUEST_METHOD']!='POST')
{
    $form = <<<FORM
<form action="" method="POST">
<fieldset style="width: 700px;">
<legend>Enter your search below</legend>
<textarea rows="1" cols="80" name="query">
</textarea>
</fieldset>
<p>
<input type="radio" value="Non-Aggregated" name='radioCheck'> Non-Aggregated
<input type="radio" value="Aggregated" name='radioCheck'> Aggregated 
&nbsp;
&nbsp;
<input type="submit" value="Search">
</p>
</form>
FORM;
echo $form;
}
elseif($_SERVER['REQUEST_METHOD']=='POST' && isset($_POST['radioCheck']) && $_POST['radioCheck'] =='Non-Aggregated'){

// Non-Aggregated form
    echo 'Non-Aggregated';

}elseif($_SERVER['REQUEST_METHOD']=='POST' && isset($_POST['radioCheck']) && $_POST['radioCheck'] =='Aggregated'){
// Aggregated form

    echo 'Aggregated';
}
?>
