PHP 多个单选按钮
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.
