Introduction
✔ Started by Taylor Otwell (a c# developer).
✔ PHP V>= 5.3 based MVC framework.
✔ Hugely inspired by other web framework including

✔ Has a command line interface called as Artisan
✔ Current stable version available is 4.1
Presenter: Nikhil Agrawal, Mindfire Solutions

Features out-of-the-box
✔ Flexible routing
✔ Powerful ActiveRecord ORM
✔ Migration and seeding
✔ Queue driver
✔ Cache driver
✔ Command-Line Utility (Artisan)
✔ Blade Template
✔ Authentication driver
✔ Pagination, Mail drivers, unit testing and many more
Presenter: Nikhil Agrawal, Mindfire Solutions

6. 6
Setup
✔ Install Composer
curl -sS https://getcomposer.org/installer | php
✔ It is a dependency manager
✔ What problem it solves?
✔ composer.json, composer.lock files
✔ Install laravel / create-project.
✔ Folder structure
✔ Request lifecycle
✔ Configuration
Presenter: Nikhil Agrawal, Mindfire Solutions

7. 7
Artisan
✔ Artisan is a command-line interface tool to speed up
development process
✔ Commands
✔ List all commands : php artisan list
✔ View help for a commands : php artisan help migrate
✔ Start PHP server : php artisan serve
✔ Interact with app : php artisan tinker
✔ View routes : php artisan routes
✔ And many more...
Presenter: Nikhil Agrawal, Mindfire Solutions

8. 8
Routing
✔ Basic Get/Post route
✔ Route with parameter & https
✔ Route to controller action
Route::get('/test', function() {
return 'Hello'
})
Route::get('/test/{id}', array('https', function() {
return 'Hello'
}));
Route::get('/test/{id}', array(
'uses' => 'UsersController@login',
'as' => 'login'
)
)
Presenter: Nikhil Agrawal, Mindfire Solutions

9. 9
Routing cont..
✔ Route group and prefixes
✔ Route Model binding
✔ Url of route:
✔ $url = route('routeName', $param);
✔ $url = action('ControllerName@method', $param)
Route::group(array('before' => 'auth|admin', 'prefix' => 'admin'), function (){
//Different routes
})
Binding a parameter to model
Route::model('user_id', 'User');
Route::get('user/profile/{user_id}', function(User $user){
return $user->firstname . ' ' . $user->lastname
})
Presenter: Nikhil Agrawal, Mindfire Solutions

10. 10
Controller
✔ Extends BaseController, which can be used to write logic
common througout application
✔ RESTful controller
✔ Defining route
Route::controller('users', 'UserController');
✔ Methods name is prefixed with get/post HTTP verbs
✔ Resource controller
✔ Creating using artisan
✔ Register in routes
✔ Start using it
Presenter: Nikhil Agrawal, Mindfire Solutions

11. 11
Model
✔ Model are used to interact with database.
✔ Each model corresponds to a table in db.
✔ Two different ways to write queries
1. Using Query Builder
2. Using Eloquent ORM
Presenter: Nikhil Agrawal, Mindfire Solutions

12. 12
Query Builder (Model)
✔ SELECT
✔
$users = DB::table('users')->get();
✔ INSERT
✔ $id = DB::table('user')
->insertGetId(array('email' =>'nikhila@mindfire.com',
'password' => 'mindfire'));
✔ UPDATE
✔ DB::table('users')
->where('active', '=', 0)
->update(array('active' => 1));
✔ DELETE
✔ DB::table('users')
->delete();
Presenter: Nikhil Agrawal, Mindfire Solutions

13. 13
Eloquent ORM (Model)
✔ Defining a Eloquent model
✔ Class User Extends Eloquent { }
✔ Try to keep the table name plural and the respective model as singular (e.g
users / User)
✔ SELECT
✔ $user = User::find(1) //Using Primary key
✔ $user = User::findorfail(1) //Throws ModelNotFoundException if
no data is found
✔ $user = Menu::where('group', '=', 'admin')->remember(10)->get();
//Caches Query for 10 minutes
✔ INSERT
✔ $user_obj = new User();
$user_obj->name = 'nikhil';
$user_obj->save();
✔ $user = User::create(array('name' => 'nikhil'));

14. 14
Query Scope (Eloquent ORM)
✔ Allow re-use of logic in model.
Presenter: Nikhil Agrawal, Mindfire Solutions

15. 15
Many others Eloquent features..
✔ Defining Relationships
✔ Soft deleting
✔ Mass Assignment
✔ Model events
✔ Model observer
✔ Eager loading
✔ Accessors & Mutators

16. 16
View (Blade Template)
Presenter: Nikhil Agrawal, Mindfire Solutions

17. 17
Loops
View Composer
✔ View composers are callbacks or class methods that are called when
a view is rendered.
✔ If you have data that you want bound to a given view each time that
view is rendered throughout your application, a view composer can
organize that code into a single location
View::composer('displayTags', function($view)
{
$view->with('tags', Tag::all());
});
Presenter: Nikhil Agrawal, Mindfire Solutions

18. 18
Installing packages
✔ Installing a new package:
✔ composer require <packageName> (Press Enter)
✔ Give version information
✔ Using composer.json/composer.lock files
✔ composer install
✔ Some useful packages
✔ Sentry 2 for ACL implementation
✔ bllim/datatables for Datatables
✔ Way/Generators for speedup development process
✔ barryvdh/laravel-debugbar
✔ Check packagist.org for more list of packages
