PHP 多个单选按钮

PHP multiple radio buttons(PHP 多个单选按钮)

问题描述

如何处理页面中的所有单选按钮?

how can i process all radio buttons from the page?

<input type="radio" name="radio_1" value="some" />
<input type="radio" name="radio_1" value="some other" />

<input type="radio" name="radio_2" value="some" />
<input type="radio" name="radio_2" value="some other" />

这个按钮将被动态添加，所以我不知道单选按钮的名称(以及按钮的数量).有没有办法通过 for 循环或类似的方法获取所有无线电值?谢谢

this buttons will be added dynamically so i will not know the radio buttons name(and also the number of the buttons). Is there a way to get all radio values, with a for loop or something like this? thanks

推荐答案

使用 foreach 循环

<?php
foreach ( $_POST as $key => $val )
    echo "$key -> $val
";
?>

$key 将是所选选项的名称，$val 是值.

$key will be the name of the selected option and $val, well, the value.
