Seegatesite.com – Routes, Model, View, Controller is an important concept to the laravel framework . This is my third article on tutorial laravel framework. If you need to start learning how to install laravel 5 , please follow my tutorial here. Before we go further to create project using laravel we must understand the true concept of MVC and Routes in advance. I myself while writing this article is still on learning phase for using laravel framework. Let us learn together 🙂

Routes resemble custom permalink at the wordpress. With the route we can write the url name according to our will.

Routes on the laravel set on /app/Http/routes.php . Script routes.php by default as shown below

Create About Page Routes Learn To Understand Routes On Laravel 5 For Beginners

In this article I have eliminated the a public url in laravel 5, so that when accessing the home page , the url be as follows http://localhost/your-domain/ or http://your-domain.com/ . If you not yet eliminate the public url in laravel 5 framework, please access the about page with following url : http://localhost/your-folder/public/about or read my article about Best Way Eliminate Public Folder in the URL Laravel 5

A little explanation of the route script above

– Get parameter show us to send GET request.
– ‘/about’ is a custom URL that we create in order to access the about page
– Function(){…} is a closure that will provide answers to the request that we sent. In addition to the closure we can direct the request to a controller function as Route to call the welcome page url.

In the routes.php default script we see code like the following

Route::get(‘/’, ‘WelcomeController@index’);

Explanation:

– ‘/’ an index page / homepage.
– laravel 5 will run a controller named WelcomeController (in the folder /app/Http/Controllers/WelcomeController) and executes the index method / function contained in WelcomeController.

Usually, a beginner like me when trying to learn routes will experience a 404 error (page not found). The problem occurs because of the possibility of setting httpd.conf or apache2.conf (ubuntu 14). You can try the following solution

How to solve 404 error page not found on routes laravel on ubuntu

  • sudo a2enmod rewrite
  • Edit /etc/apache2/apache2.conf (sudo gedit /etc/apache2/apache2.conf) and change AllowOverride None to AllowOverride All
  • sudo service apache2 restart

As an experiment create a new Route in routes.php with the script as follows

Route::Get('/profile','WelcomeController@profile');

and back to WelcomeController.php and add the following code at the bottom of the index function

1
2
3
function profile(){
return 'This is profile page';
}

Please analysis the results
