Because we don't -want to write a separate method for every page, we made the view method -accept one parameter, the name of the page. These hard coded pages will -be located in application/views/pages/. Create two files in this -directory named home.php and about.php and put in some HTML content. - -In order to load these pages we'll have to check whether these page -actually exists. When the page does exist, we load the view for that -pages, including the header and footer and display it to the user. If it -doesn't, we show a "404 Page not found" error. - -public function view($page = 'home') { if ( ! -file\_exists('application/views/pages/' . $page .

We use PHP's native file\_exists() to do this check -and pass the path where the file is supposed to be. Next is the function -show\_404(), a CodeIgniter function that renders the default error page -and sets the appropriate HTTP headers. - -In the header template you saw we were using the $title variable to -customize our page title. This is where we define the title, but instead -of assigning the value to a variable, we assign it to the title element -in the $data array. The last thing we need to do is loading the views in -the order we want them to be displayed. We also pass the $data array to -the header view to make its elements available in the header view file. - -Routing -------- - -Actually, our controller is already functioning. Point your browser to -index.php/pages/view to see your homepage. When you visit -index.php/pages/view/about you will see the about page, again including -your header and footer. Now we're going to get rid of the pages/view -part in our URI. As you may have seen, CodeIgniter does its routing by -the class, method and parameter, separated by slashes. - -Open the routing file located at application/config/routes.php and add -the following two lines. Remove all other code that sets any element in -the $route array. - -$route['(:any)'] = 'pages/view/$1'; $route['default\_controller'] = -'pages/view'; - -CodeIgniter reads its routing rules from top to bottom and routes the -request to the first matching rule. These routes are stored in the -$route array where the keys represent the incoming request and the value -the path to the method, as described above. - -The first rule in our $routes array matches every request - using the -wildcard operator (:any) - and passes the value to the view method of -the pages class we created earlier.
