Title: Troubleshooting Laravel 5.1 Route Issues
Body:
The issue you are experiencing with Laravel 5.1 involves a 404 error when loading views created through controllers. Though it seems you have followed the proper steps of creating a controller, view, and layout, there might be some potential issues in your configuration that may cause this problem. We will go through each step to ensure everything is set up correctly so your application runs smoothly.
1. Route Configuration: Ensure your routes are properly defined in the `routes.php` file. Make sure you have included a route for your authors controller with an appropriate URL format. Here's how it should look:
```php
Route::get('authors', array('as' => 'authors', 'uses' => 'Authors@index'));
```
2. View Configuration: Your layout and view files are correctly configured; however, routing might still cause an error. Check if you have any other routes that may interfere with your author route or conflict with the URL path. Ensure there is no mismatch in the route declaration within `routes.php`. If any issue arises, adjust the order of your routes accordingly to prevent conflicts.
3. Route Configuration for Subdomains: Since you are using a subdomain (`sub.example.com`) instead of your main domain, you may need to specify this in your route configuration. You can add the following line at the beginning of `routes.php`:
```php
if (!isset($_SERVER['HTTP_X_FORWARDED_HOST']) || $_SERVER['HTTP_X_FORWARDED_HOST'] !== 'sub.example.com') {
return Redirect::to('https://sub.example.com/laravel/public');
}
```
4. Route Configuration for Subfolders: If you have your Laravel installation within a subfolder, such as `/laravel`, ensure that the route configuration reflects this as well. You can adjust the route accordingly by including the necessary path prefix in your route declaration:
```php
if (!isset($_SERVER['HTTP_X_FORWARDED_HOST']) || $_SERVER['HTTP_X_FORWARDED_HOST'] !== 'sub.example.com') {
return Redirect::to('https://sub.example.com/laravel/public');
}
Route::get('authors', array(...));
```
5. Check Permissions: Ensure the user running your web server has proper permissions to read and execute all the files within your Laravel installation, including `routes.php`, controller classes, views, layouts, etc., as well as any other related directories and files.
6. Clear Cache: Since you mentioned that your controller is working fine for another route, there might be a possibility of caching issues. Clear the cache using the `artisan` command-line tool:
```bash
php artisan cache:clear
```
7. Route Casing: Ensure that your route URLs are following proper casing conventions since Laravel supports both lowercase and uppercase letters in routes but expects consistency across the application. Make sure your browser is not changing the case of the requested file.
8. Error Logging: Check your Laravel error logs to ensure no errors were encountered during the execution of your routes. You can find these logs within `storage/logs`. If you have configured your route correctly, it should output the view as expected without any issues.
If none of these suggestions resolve the issue, make sure that your browser is following the redirect URLs correctly and not causing caching issues on its own.
