Redirecting to 404

  Hmm got a little bit closer... via debugging I ended up in the library Fuel_pages initialize. There a page is created with the default layout main...
  Have I configured something wrong? From my understanding the 404 override should have happened earlier...

  By default, Fuel handles the 404 and presents the ./views/_layout/404_error.php
  
  Put your custom code in there.
  
  The 404 route is configured in ./config/routes.php

  aaaaaaaaaah thanks... that was the missing link...
  config/routes.php says $route['404_override'] = 'fuel/page_router';
  
  ;-)
  
  And I am wondering why it results in the page router :-)

  hmmm I have now a controller Error
  <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Error extends CI_Controller { public function error404() { $this->fuel->pages->render("404notfound", $data, array('render_mode' => 'cms')); } } /* End of file error.php */ /* Location: ./application/controllers/error.php */ ?>
  
  and my routes.php says
  $route['default_controller'] = 'homepage'; $route['404_override'] = 'error/error404'; $route['admin'] = 'fuel';
  
  On calling a non existing url I get the error
  An Error Was Encountered
  Unable to load your default controller. Please make sure the controller specified in your Routes.php file is valid.

  What if you change the method name of "error404" to just "index" and then change the route to:
  $route['404_override'] = 'error';

  hmmm ok. Now the controller is found. But that was not the whole trick...
  I have 2 layouts in my CMS. The main layout for simple cms content pages and a module layout for more custom pages generated on base of simple modules in the cms.
  
  All pages now are redirected to the error page, although they are existing in the cms.

  I debugged the routing... File Router.php in modules/fuel/core method _validate_request
  $this->locate does not return anything for the given segments, because the cms routes are not loaded into $this->routes

  If you overwrite the 404_override route, then all non-controller pages will get routed there instead which means all pages in the CMS will need to be rendered via another controller.

  I solved the problem for my installation by creating a my_page_router controller and overriding the _remap function.
  
  if (!array_key_exists(uri_path(TRUE), $this->fuel->pages->cms()) && uri_path(TRUE) != "offline") { $this->location = "404notfound"; } else { $this->location = uri_path(TRUE); }
  
  For my installation this works, because the offline page is the only page generated in view_mode.

  not array_key_exists but in_array must be used.
  But this is not the whole solution... this does not take into account urls with a / at the end and the module detail pages with the id as suffix are not recognized correctly...
  
  I think I need to spend some more thoughts into this ...
  I want to achieve the following:
  1. all non existing pages should be redirected to 404 cms page
  2. all existing pages should be recognized no matter if the url is http:///page or http:///page/
  3. all non existing detail pages (if the user enters a non existing ID into the url) should produce a readable result
  
  I think 3. can be achieved in the models of the corresponding model... am I right?

  Ok... I think I got 1 and 2 with
  if (!in_array(uri_path(TRUE), $this->fuel->pages->cms()) && uri_path(TRUE) != "offline") { $uri_path = uri_path(TRUE); if (substr($uri_path, -1) == "/") { $uri_path = rtrim($uri_path, "/"); } elseif (is_numeric(substr($uri_path, strrpos($uri_path, "/") + 1))) { $uri_path = rtrim($uri_path, substr($uri_path, strrpos($uri_path, "/"))); } if (!in_array($uri_path, $this->fuel->pages->cms())) { $this->location = "404notfound"; } else { $this->location = uri_path(TRUE); } } else { $this->location = uri_path(TRUE); }
  in the file my_page_router function _remap($method).

  If the detail pages are generated from a model's data, you can look at the module's post pages example:
  http://docs.getfuelcms.com/modules/simple#post_pages
  
  Note that in the example there is a 'empty_data_show_404' parameter you can use to

  I am not using the generated post pages at them moment...
  my module config looks like
  $config['modules']['missions'] = array( 'module_name' => 'Einsätze', 'instructions' => lang("einsatz_instructions"), 'permission' => 'missions', 'item_actions' => array('save', 'view', 'publish', 'activate', 'delete', 'duplicate', 'create') );
  The overview and detail page are generated via the layout _module.php
  
  Is a usage of the empty_data_show_404 parameter also possible in this case?

  That parameter is only applicable to post pages. It sounds like in your case you'll need to add some code in your layout_model.php file to display content if no model record exists.

  Hi,
  the problem was that the fuel redirect for 404 expects a page named 404_error in the cms. My paged was named different...
