路由时出错404

Question

I'm trying to do my site like this tutorial http://www.codeigniter.com/user_guide/tutorial/static_pages.html

but have some problem with routing. I have page "createBook" for default and when I call localhost it's work! But when I do like localhost/createBook I have Error 404. What I'm doing wrong?

In my controller:

    public function view($page = 'createBook')
{
        if ( ! file_exists(APPPATH.'views/'.$page.'.php'))
        {
                // Whoops, we don't have a page for that!
                show_404();
        }
        $this->load->view($page);
}

routes.php file

$route['default_controller'] = 'Books/view';
$route['(:any)'] = 'Books/view/$1';

And I have view files in my views folder named Success and createBook

I don't really get your question but it seems to me that you are trying to call a controller named createBook from the url, but in your function it shows that if there is no views/createBook.php than show 404, maybe its why you get a 404, because your calling a controller as a view, i think your function should be like this :

public function view($page = 'createBook')
{
  if ( ! file_exists(APPPATH.'controllers/' . $page . '.php'))
    {
     // Whoops, we don't have a page for that!
     $this->output->set_status_header('404');
     show_404();
    }
  $this->load->view($page);
}

If you want your url to look something like this :

example.com/view/book/3

Your controller should look like this :

class View extends CI_Controller 
{
  public function book($book_id) 
    {
     //Search the database for records about a book with its id, and return the data
     //and assign it to a variable(in this case $data) ex : $data["book-name"] = ...
     //And on your view you can call these values using ex : echo $book-name
     $this->load->view('books_view', $data);
    }
}

And make sure your .htaccess file next to the index.php looks like something like this :

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Then go to your config, and change this line to :

$config['index_page'] = '';

Now you can access all of your controllers this way :

http://www.example.com/controller_name
