Using Events on Laravel Eloquent

Eloquent models fire several events, allowing you to hook into the following points in a model's lifecycle: creating, created, updating, updated, saving, saved, deleting, deleted, restoring, restored.

Accessors and Mutators in Laravel

Defining An Accessor To define an accessor, create a getFooAttribute method on your model where Foo is the "studly" cased name of the column you wish to access.

The accessor will automatically be called by Eloquent when attempting to retrieve the value of the first_name attribute: <?php namespace Ap...

CSRF Protection in Laravel

Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that ...

Resourceful Controllers in Laravel

Resource Controllers Laravel resource routing assigns the typical "CRUD" routes to a controller with a single line of code.

Using the make:controller Artisan command, we can quickly create such a controller: php artisan make:controller PhotoController...

Many To Many Relationships Laravel

Attaching / Detaching Eloquent also provides a few additional helper methods to make working with related models more convenient. For example, let's imagine a user can have many roles and a role can have many users. To attach a role to a user by inserting a record in the intermediate table that joins the models, use the attach() method: $user = App\User::find(1); $user->roles()-&...

Eager Loading in Laravel

When accessing Eloquent relationships as properties, the relationship data is "lazy loaded". This means the relationship data is not actually loaded until you first access the property. However, Eloquent can "eager load" relationships at the time you query the parent model. Eager loading alleviates the N + 1 query problem. To illustrate the N + 1 query problem, consider a Book ...
