由 [亡魂溺海] 提交于 2019-12-07 21:49:06

CodeIgniter: unset all userdata, but not destroy the session

由 别说谁变了你拦得住时间么 提交于 2019-12-07 14:13:36
问题 Is there a way to unset ALL userdata in a session without having to use session destroy? I'm trying to log my user out and need to unset all userdata one at a time. It's becoming tedious to keep track of all possible userdata set in session. I just want to unset everything that might have been set in userdata. 回答1: This is very simple! $this->session->unset_userdata('some_name'); or $array_items = array('username' => '', 'email' => ''); $this->session->unset_userdata($array_items); I hope

由 99封情书 提交于 2019-12-07 09:10:17
问题 I have Ion Auth properly installed and working on my server. I also have the default CodeIgniter 2 "news" tutorial working in the same CI installation. I'm just playing around and curious about the proper way to use the authentication system to "enclose" or protect an entire application. For this question, let's use the "news" tutorial that comes with CI. Inside the index() function in my news.php controller, I added conditional code to check if the user is logged in. If not, the user is just

Custom error pages with templates in CodeIgniter

由 天涯浪子 提交于 2019-12-07 05:04:06
问题 I'm using the template library for CodeIgniter, http://williamsconcepts.com/ci/codeigniter/libraries/template/reference.html, and now I want to implement custom error pages too. I found one method involving a MY_Router extending the default router: http://maestric.com/doc/php/codeigniter_404 but that only treats 404 errors. I want all errors to show a simple user-friendly page, including database errors etc, and I want it to go through a controller, partly so I can use the template library,
