Answer 1

Required things to access any page of codeigniter are:
First letter of controller file must be capital like Suppliers.php.
The first letter of the class definition must match the filename, e.g. for Suppliers.php it would be class Suppliers extends CI_Controller.
If a database is to be used, then the correct connection details must be set in the file config/database.php.
Below are the steps to access the any page created in the codeigniter.
Write your site domain followed by index.php, e.g. http://mysitedomain.com/index.php/suppliers
To remove the need for index.php in the URL add an .htaccess file at the root folder. Details here. In that case the URL will be
http://mysitedomain.com/. Now, domain name will get followed by controller name and the function to be accessed, e.g.
http://mysitedomain.com/suppliers/show
To pass arguments to a controller using the URL add them after the controller/function segments, e.g. http://mysitedomain.com/user/show/dede
If a controller has an index function - public function index(){ - it can be accessed two ways:
A) http://mysitedomain.com/suppliers/index
B) http://mysitedomain.com/suppliers
If /function/argument URI segments are not provided after controller name, codeigniter will call index() by default.
