这是我为要显示的表单设置的Cookie代码

但总是收到未定义错误

  

索引：第3行的MagnetStatus

是

$magstatus = $_COOKIE[$cookie_name];

代码：
     

$magstatus = $_COOKIE[$cookie_name];

if(!$magstatus) {

$cookie_value = 0;
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
}

?>

所以你可以帮我解决这个问题吗？

2 个答案:

答案 0 :(得分：0)

如果具有指定名称的Cookie不存在，您可以使用isset()或empty()来阻止此类警告

$magstatus = (isset($_COOKIE[$cookie_name])) ? $_COOKIE[$cookie_name] : 'default_value_here';

答案 1 :(得分：0)

您必须使用以下代码来检查cookie是否已设置：

if(!isset($_COOKIE[$cookie_name])) {

$cookie_value = 0;
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
}

仅使用$magstatus = $_COOKIE[$cookie_name];方法

删除isset行检查Cookie
