I'm pretty new at CodeIgniter. I'm now wanting to create my first submission form to my MySQL database. My database settings are correct in the database.php in the config folder. I know that I need a view page, a controller page and a model page for this task, but I need to see some samples that I can use and test.  I found some sample view, controller and model code on this page but I'm getting an error message on my test view page. Below is line 10 in the code. Any ideas what's happening? Or do you know any other places where I can copy the view, controller and model code to try to replicate this on my own site for practice?

I have 5 problems, the 5th is a potential problem. It is probably best to deal with one problem at a time.

(1) The posted information does not load into the folders. I have tried deleting the country folder but it makes no difference.

(2) If a different Username is used it declares an error that the Username exists. The is_unique function is not working. I have tried deleting the country folder but it makes no difference.

(3) When the root folder is deleted the above errors are the same as when the folder exists.

(4) I have tried to check if username exists in the members folder, as per the coding below but that coding doesn't work.

(5) Will need to login when the information is loaded, using the Username & Password.

Basically, the coding below was taken from another person's project, which worked, but I have changed things to suit my project and the difference with that other person's project and what I'm trying to do is that the Username and Password information was loaded into a database, whereas I don't want to use a database. In that other project the Certificate was loaded into a folder in the root directory the same as what I'm trying to do, but I also want to load the Username and Password into the root directory folders the same as the Certificate. Also in that other person's project there was no country folder. All of that maybe the cause of my problems but I don't know how to fix, despite studying the CI UserGuide.

The coding below creates the folders in the root directory as expected and as follows.

accounts/afghanistan/realname/username
accounts/afghanistan/realname/password
accounts/afghanistan/realname/certificate

But no information or pdf files are entered.

I would want the Username & Password information to be in PHP format.

I'm building a web app for an educational non-profit and teachers volunteering for the non-profit need to make updates to CodeIgniter pages. What is a good CMS for CodeIgniter to use in such a case?

Hello,

If fact it's simple, I use CI and in my admin I use the $_SESSION['auth'] to secure my admin.

In my admin I use ckeditor with fileman as image uploader.

I need to secure fileman by use my $_SESSION['auth'] variable, but there is no $_SESSION variable in security.php which is the file to secure fileman.

I can just retrieve the variable ci_session, this is a part of extract_var($GLOBALS).

'_COOKIE' => 
 array (
   'PHPSESSID' => 'bkf4lii33uvilgle2294ja3dn2',
   'ckCsrfToken' => 'RcUP2LBI2Ad74hDzLFj6d7kGtAMTKCUPKPASZdd3',
   'KCFINDER_showname' => 'on',
   'KCFINDER_showsize' => 'off',
   'KCFINDER_showtime' => 'off',
   'KCFINDER_order' => 'name',
   'KCFINDER_orderDesc' => 'off',
   'KCFINDER_view' => 'thumbs',
   'KCFINDER_displaySettings' => 'off',
   'ci_session' => 'm5hu8v0ffv3jmvfe1n6vj2bkhgoa5t32',
   'roxyview' => 'thumb',
   'roxyld' => '/fileman/upload',
 ),

my question is simple, is it possible to retrieve my $_SESSION['auth'] variable with my ci_session number ?

It looks like the email notification doesn't work anymore. I no longer receive email when somebody reply to a thread I'm subscribed to.

What's the difference between these two below? Why would one be better than the other? I'm new so I new to PHP, so an easy-to-understand answer would be helpful.

I'm new with composer, so I'm not sure what I am doing. I installed the app starter with composer some time ago. Now I do a "composer update" and it won't update to beta 4. In composer.lock the version is v4.0.0-beta.3, if I change it for beta.4 it revert back to beta.3.
