How to determine whether a user is logged in in phpcms? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

First, the "_ userid" data is obtained by using the "get_cookie ()" method in the "param" class; then the value is assigned to the new variable; finally, the PHP syntax or "if" tag is used in the template to determine the new variable.

Sample code

{if $userid}. The code after login is written here. {else} . The code after login is written here. {/ if} defined ('IN_PHPCMS') or exit (' No permission resources.'); class MY_index extends index {private $times_db; public function _ construct () {parent::__construct ();} public function top_mini () {$_ username = param::get_cookie ('_ username'); $_ userid = param::get_cookie ('_ userid') $siteid = isset ($_ GET ['siteid'])? Intval ($_ GET ['siteid']):''; $jsoncallback=isset ($_ GET ['jsoncallback'])? $_ GET [' jsoncallback']:''; / / define the site id constant if (! defined ('SITEID')) {define (' SITEID', $siteid);} if ($_ username) {$res ["success"] = 1 $res ["message"] ='.L ('hellow').;;. Get_nickname (). Welcome home;'.L ('member_center').'; |; publish information; |;'L ('logout').'; $res ["message"] = pc_base::load_config ('system',' charset') = 'gbk'? Iconv ('utf-8',' utf-8', $res ["message"]): $res ["message"]; / / get_nickname (); / /,} else {$res ["success"] = 0;} if ($jsoncallback) {echo $jsoncallback. "({\" items\ ": [" .json _ encode ($res). "]})";} else {echo json_encode ($res);} / / echo json_encode ($res) This is the answer to the question about how to judge whether a user is logged in in phpcms.
