如何设置一个cookie,然后在PHP中重定向? [英] How can I set a cookie and then redirect in PHP?
问题描述
经过一些处理之后,我想为用户输入设置一个cookie值,然后将它们重定向到一个新页面。但是,cookie未设置。如果我注释掉重定向,那么cookie设置成功。我认为这是一个头部问题的某种。这种情况的最佳解决方法是什么?
if($ form_submitted){
...
setcookie('type_id',$ new_type_id,time()+ 60 * 60 * 24 * 30);
header(Location:$ url);
exit;
}
注意setcookie返回 true $ c $
如果您有人类URL或子文件夹(如www.domain.com/path1/path2/),那么必须设置cookie
if($ form_submitted){
.. 。
setcookie('type_id',$ new_type_id,time()+ 60 * 60 * 24 * 30,'/');
header(Location:$ url);
exit;
}
从PHP手册:
在
cookie可用的服务器上的路径。如果设置为
'/',则cookie将在整个域中可用
。如果设置为
'/ foo /',那么cookie只能是/ foo /目录
中的
和所有子目录,例如
/ foo / bar /域。默认的
值是
设置cookie的当前目录。
After doing a bit of processing, I want to set a cookie value to user input and then redirect them to a new page. However, the cookie is not getting set. If I comment out the redirect, then the cookie is set successfully. I assume this is a header issue of some sort. What is the best workaround for this situation?
if($form_submitted) {
...
setcookie('type_id', $new_type_id, time() + 60*60*24*30);
header("Location: $url");
exit;
}
Note that setcookie returns true
in either case and I get no errors/warnings/notices.
EDIT: I am using Unix/Apache/MySQL/PHP
If you have human urls or subfolders (like www.domain.com/path1/path2/), then you must set cookie path to / to work for all paths, not just current one.
if($form_submitted) {
...
setcookie('type_id', $new_type_id, time() + 60*60*24*30, '/');
header("Location: $url");
exit;
}
From PHP manual:
The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain . If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain . The default value is the current directory that the cookie is being set in.
