定义和用法 当用户从若干给定的的选择中选取其一时,就会用到单选框。
语法<input type="radio" name="sex" value="male"> 男
<input type="radio" name="sex" value="female"> 女
参数说明type 表单的类型。其中的radio表示单选按钮。
name 选项的名称。可以自己定义名称。
value 是单选按钮的值,上例中“男”对应的值就是 male,“女”对应的值就是"female"
实例<?php
if($_POST[Submit]=="提交"){ //如果用户提交了数据
echo "你选择的是".$_POST[Sex];   //输出单选按钮的值
}
?>
