 <form id ="btnform"action="login.php" method="post">        一:        <input type="radio" name="name" value="10"> 10        <input type="radio" name="name" value="20"> 20        <input type="radio" name="name" value="30"> 30        <br/>        二:        <input type="radio" name="name2"  value="100"> 100        <input type="radio" name="name2"  value="200"> 200        <input type="radio" name="name2"  value="300"> 300        <br/>        三:        <input type="text" name="name3">        <br/>        </form>
Copy after login


如图表单提交后输出post
Array
(
[name] => 20
[name3] =>
)
为什么Array里没 name2 ?
//如果没有我就让它的值为空(如下),但是会报错,说没有name2$list['name2']=isset($_POST['name2'])?$_POST['name2']:"";
Copy after login


回复讨论(解决方案)

没有被选中的的单选钮和复选框是不会被提交的

没有被选中的的单选钮的值是不会被提交的

没有被选中的的单选钮不会提交,所以没有name2 。但是你用isset检查应该不会报错的啊。
