PHP形式多个单选按钮 [英] php form multiple radio buttons

问题描述

我试图找到一种通用的方式来调出哪个单选按钮已被选中。
问题是，在我的foreach循环中使用$ _GET时，同时提交按钮也是循环中的回显。

I'm trying to find a generic way to call out which radio button has selected. Problem is, while using $_GET in my foreach loop, also submit button is echo in the loop.

任何人都可以告诉我如何避免这种情况，所以我只是显示单选按钮？
我不知道一种方法，因为foreach只是接受数组，据我所知

Can anyone tell me how to avoid this, so that I just show up the radio buttons? I do not know a way, because foreach just accepts arrays as far as I know

这里是我的代码

<form action="" method="get">
<input type="radio" name="one" value="One1" />One1<br/>
<input type="radio" name="one" value="One2" />One2 <br/>
<input type="radio" name="one" value="One3" />One3<br/>
<input type="submit" name="submit"/> <br/>
</form>



if(isset($_GET['submit'])){
    foreach( $_GET as $key=>$val){
        echo "$val <br/>";
    }
}

推荐答案

just如果你的循环中的条件不会在你的表单中显示提交按钮，请尝试添加。

just try to add if condition in your loop will not show submit button in your form.

if(isset($_GET['submit'])){

    foreach( $_GET as $key=>$val){
      if($key != 'submit')
        echo "$val <br/>";
    }
}
