php - CI index method/function not automatically added for some cases? -

if give method/function's name index in codeigniter, can go method without calling (so need use controller name).

that because specify (or ci specifies default) in config.php :

$config['index_page'] = 'index.php'; 

so when use library form_validation, don't need specify index method. however, have problem when tried use pagination class.

i need specify index method in code, or pagination doesn't work (it gives 404 error if click next pagination index) :

$config['base_url'] = site_url('/backend_umat'); 

so, have use :

$config['base_url'] = site_url('/backend_umat/index'); 

and pagination works perfectly.

please, can kindly give me explanation what's going on? problem solved, i'm curious what's going on here.

thanks :d

in codeigniter pagination:

• $config['base_url'] should complete url. i.e., base_url()/{controller}/{function}.
  
• so if not giving complete path, pagination class ignore {function} , create links like:
  

base_url()/{controller}/{page1} , base_url()/{controller}/{page2} , base_url()/{controller}/{page3} , on... instead of base_url()/{controller}/{function}/{page_no}

in place of function there's number (page number) not present in controller class assumed function inside controller. that's reason getting 404 page not found error.

there 2 ways solve this.

1. the way have done it. $config['base_url'] = site_url('/backend_umat/index');
2. use routes.
   inside routing.php file define this:
   $route['backend_umat/(:num)'] = 'backend_umat/index/(:num)';
   in controller: $config['uri_segment'] = 2;
   , if have used: $this->uri->segment(3) in code, make $this->uri->segment(2)
   do.
