php - Codeigniter 3.0.0 - error 404 page not found -

this first php framework. have php file in controller posts.php when tried run localhost/codeigniter/index.php/posts, displays error 404

.htaccess inside application folder

<ifmodule authz_core_module> require denied </ifmodule> <ifmodule !authz_core_module> deny </ifmodule> 

autoload.php

$autoload['libraries'] = array('database'); $autoload['helper'] = array('url'); 

config.php

$config['base_url'] = 'http://localhost/codeigniter/'; $config['index_page'] = 'index.php'; 

routes.php

$route['default_controller'] = 'welcome'; $route['404_override'] = ''; $route['translate_uri_dashes'] = false; 

post.php in model folder

    class post extends ci_model{      function get_posts($num = 20, $start = 0){          //$sql = "select * users active=1 order date_added desc limit 0,20;";         $this->db->select()->from('posts')->where('active', 1)->order_by('date_added', 'desc')->limit(0, 20);         $query=$this->db->get();         return $query->result_array();      }  } 

posts.php in controller folder

class posts extends ci_controller{      function index(){          $this->load->model('post');         $data['posts'] = $this->post->get_posts();         echo "<pre>";             print_r($data['posts']);         echo "</pre>";            }  } 

it should display empty array shows error 404 instead

when using codeigniter 3

all controllers , models should have there first letter of class name , file name upper case example welcome.php , not welcome.php

for model because same name controller. change model name model_post

filename: model_post.php

<?php  class model_post extends ci_model {      public function some_function() {      }  } 

that way codeigniter not confused.

post controller

filename: post.php

<?php  class post extends ci_controller {      public function __construct() {        parent::__construct();        $this->load->model('model_post');     }     public function index() {       $this->model_post->some_function();    }  } 

also in url if not set codeigniter / htaccess remove index.php url need use index.php every where.

http://localhost/project/index.php/post  http://www.example.com/index.php/post 

note: not touch htaccess in application folder if need htaccess add 1 in main directory htaccess codeigniter

previous versions of codeigniter before v3 did not need worry ucfirst controllers version 3 , above.
