In this tutorial, we are going to learn how to intergrade Srilankan University, Faculty, Degreee PHP package to our Laravel application. You can see the working demo of this application form here. When we need to take the extract Degree programme based on the University and Faculty, you can use this package:

  • Contain all the Government Universities in Srilanka
  • Contain all the Faculties related to particular Unversity
  • Contain all the Degree programmes related to particular Faculty

    • Prerequisites

  • Laravel
    • To Continue with this tutorial, you should have installed Laravel 8 in your pc. If you are still not installed Laravel in your machine you can configure it from here.

    Setting up the Project

    First you need to create a new laravel project by running below command in your terminal
    1
    composer create-project laravel/laravel srilankan-universities

    Then navigate to your project directory by using below command in your terminal

    1
    cd srilankan-universities

    In this demostration,we don’t need to connect our application to Database because we work with the front-end but depend on your project you have to set up your Database.

    Install Srilankan Universities package

    Now we need to install Srilankan Universitiespackage to our application.To install Srilankan Universities package, you need to run below command in your terminal:

    1
    composer require dinushchathurya/srilankan-universities

    Create Controller

    Now we need to create a controller to handle our functions. To create a new controller in your application run below command in your terminal:

    1
    php artisan make:controller HomeController

    Then naviagate to your newly created Controller and paste below code on it:

    <?php

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;
    use Devninja\University\University; /* Import package to our application */

    class HomeController extends Controller
    {
        public function index()
        {
            $universities = University::getUniversities();
            return view('welcome')->with([
                'universities' => $universities
            ]);
        }

        public function getFaculties($name)
        {
            $faculty = University::getFaculties($name);
            return response()->json($faculty);
        }

        public function getDegrees($name)
        {
            $degree = University::getDegrees($name);
            return response()->json($degree);
        }
    }

    Now we have finished our coding part with our controller. Next, we need to create our views.

    Create Views

    Inside resources -> views folder create, folder called layouts. Then create an app.blade.php file inside i and add the following code.

    Note: Here I have used a premium and licensed template to get a better and interactive output from our application. If you need to use this template you need to purchase it from it's respective owners.

    Next, you need to create a folder called inc in layouts directory and create two seperate file called left_nav.blade.php and top_navbar.blade.php and paste below codes:
