先贴测试代码吧 test.php<?php
function add($value){
setcookie("CookieName[]",$value); //CookieName换成radio控件的name

print_r($_COOKIE['CookieName']);
?>
</form></body>
</html>说说期望的效果吧！希望单击任一radio控件时自动添加一个cookie，其name为radio的name（可以看到各选项的name是不同的）,值为所选择的radio值；页面重载或刷新时遍历页面的每一个radio控件，之前有做选择的显示其选择项，没做选择的则保持不变。
还有一点不明白，添加cookie要到下一个页面才能生效，或者说要刷新一次。那么是不是要在每次点击radio后都自动刷新一下呢？求大虾不吝赐教！！！！
