Upgrade Guide

Upgrading To 5.0 From 4.2

Fresh Install, Then Migrate

The recommended method of upgrading is to create a new Laravel 5.0 install and then to copy your 4.2 site's unique application files into the new application. This would include controllers, routes, Eloquent models, Artisan commands, assets, and other code specific to your application.

To start, install a new Laravel 5 application into a fresh directory in your local environment. We'll discuss each piece of the migration process in further detail below.

Composer Dependencies & Packages

Don't forget to copy any additional Composer dependencies into your 5.0 application. This includes third-party code such as SDKs.

Some Laravel-specific packages may not be compatible with Laravel 5 on initial release. Check with your package's maintainer to determine the proper version of the package for Laravel 5. Once you have added any additional Composer dependencies your application needs, run composer update.

Namespacing

By default, Laravel 4 applications did not utilize namespacing within your application code. So, for example, all Eloquent models and controllers simply lived in the "global" namespace. For a quicker migration, you can simply leave these classes in the global namespace in Laravel 5 as well.

Configuration

Migrating Environment Variables

Copy the new .env.example file to .env, which is the 5.0 equivalent of the old .env.php file. Set any appropriate values there, like your APP_ENV and APP_KEY (your encryption key), your database credentials, and your cache and session drivers.

Additionally, copy any custom values you had in your old .env.php file and place them in both .env (the real value for your local environment) and .env.example (a sample instructional value for other team members).

For more information on environment configuration, view the full documentation.

Note: You will need to place the appropriate .env file and values on your production server before deploying your Laravel 5 application.

Configuration Files

Laravel 5.0 no longer uses app/config/{environmentName}/ directories to provide specific configuration files for a given environment. Instead, move any configuration values that vary by environment into .env, and then access them in your configuration files using env('key', 'default value'). You will see examples of this in the config/database.php configuration file.

Set the config files in the config/ directory to represent either the values that are consistent across all of your environments, or set them to use env() to load values that vary by environment.

Remember, if you add more keys to .env file, add sample values to the .env.example file as well. This will help your other team members create their own .env files.

Routes

Copy and paste your old routes.php file into your new app/Http/routes.php.

Controllers

Next, move all of your controllers into the app/Http/Controllers directory. Since we are not going to migrate to full namespacing in this guide, add the app/Http/Controllers directory to the classmap directive of your composer.json file. Next, you can remove the namespace from the abstract app/Http/Controllers/Controller.php base class. Verify that your migrated controllers are extending this base class.

In your app/Providers/RouteServiceProvider.php file, set the namespace property to null.

Route Filters

Copy your filter bindings from app/filters.php and place them into the boot() method of app/Providers/RouteServiceProvider.php. Add use Illuminate\Support\Facades\Route; in the app/Providers/RouteServiceProvider.php in order to continue using the Route Facade.

You do not need to move over any of the default Laravel 4.0 filters such as auth and csrf; they're all here, but as middleware. Edit any routes or controllers that reference the old default filters (e.g. ['before' => 'auth']) and change them to reference the new middleware (e.g. ['middleware' => 'auth'].)

Filters are not removed in Laravel 5. You can still bind and use your own custom filters using before and after.

Global CSRF

By default, CSRF protection is enabled on all routes. If you'd like to disable this, or only manually enable it on certain routes, remove this line from App\Http\Kernel's middleware array:

'App\Http\Middleware\VerifyCsrfToken',

If you want to use it elsewhere, add this line to $routeMiddleware:

'csrf' => 'App\Http\Middleware\VerifyCsrfToken',

Now you can add the middleware to individual routes / controllers using ['middleware' => 'csrf'] on the route. For more information on middleware, consult the full documentation.

Eloquent Models

Feel free to create a new app/Models directory to house your Eloquent models. Again, add this directory to the classmap directive of your composer.json file.

Update any models using SoftDeletingTrait to use Illuminate\Database\Eloquent\SoftDeletes.

Eloquent Caching

Eloquent no longer provides the remember method for caching queries. You now are responsible for caching your queries manually using the Cache::remember function. For more information on caching, consult the full documentation.

User Authentication Model

To upgrade your User model for Laravel 5's authentication system, follow these instructions:

Delete the following from your use block:

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

Add the following to your use block:

use Illuminate\Auth\Authenticatable;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

Remove the UserInterface and RemindableInterface interfaces.

Mark the class as implementing the following interfaces:

implements AuthenticatableContract, CanResetPasswordContract

Include the following traits within the class declaration:

use Authenticatable, CanResetPassword;

If you used them, remove Illuminate\Auth\Reminders\RemindableTrait and Illuminate\Auth\UserTrait from your use block and your class declaration.

Cashier User Changes

The name of the trait and interface used by Laravel Cashier has changed. Instead of using BillableTrait, use the Laravel\Cashier\Billable trait. And, instead of Laravel\Cashier\BillableInterface implement the Laravel\Cashier\Contracts\Billable interface instead. No other method changes are required.

Artisan Commands

Move all of your command classes from your old app/commands directory to the new app/Console/Commands directory. Next, add the app/Console/Commands directory to the classmap directive of your composer.json file.

Then, copy your list of Artisan commands from start/artisan.php into the command array of the app/Console/Kernel.php file.

Database Migrations & Seeds

Delete the two migrations included with Laravel 5.0, since you should already have the users table in your database.

Move all of your migration classes from the old app/database/migrations directory to the new database/migrations. All of your seeds should be moved from app/database/seeds to database/seeds.

Global IoC Bindings

If you have any IoC bindings in start/global.php, move them all to the register method of the app/Providers/AppServiceProvider.php file. You may need to import the App facade.

Optionally, you may break these bindings up into separate service providers by category.

Views

Move your views from app/views to the new resources/views directory.

Blade Tag Changes

For better security by default, Laravel 5.0 escapes all output from both the {{ }} and {{{ }}} Blade directives. A new {!! !!} directive has been introduced to display raw, unescaped output. The most secure option when upgrading your application is to only use the new {!! !!} directive when you are certain that it is safe to display raw output.

However, if you must use the old Blade syntax, add the following lines at the bottom of AppServiceProvider@register:

\Blade::setRawTags('{{', '}}');
\Blade::setContentTags('{{{', '}}}');
\Blade::setEscapedContentTags('{{{', '}}}');

This should not be done lightly, and may make your application more vulnerable to XSS exploits. Also, comments with {{-- will no longer work.

Translation Files

Move your language files from app/lang to the new resources/lang directory.

Public Directory

Copy your application's public assets from your 4.2 application's public directory to your new application's public directory. Be sure to keep the 5.0 version of index.php.

Tests

Move your tests from app/tests to the new tests directory.

Misc. Files

Copy in any other files in your project. For example, .scrutinizer.yml, bower.json and other similar tooling configuration files.

You may move your Sass, Less, or CoffeeScript to any location you wish. The resources/assets directory could be a good default location.

Form & HTML Helpers

If you're using Form or HTML helpers, you will see an error stating class 'Form' not found or class 'Html' not found. The Form and HTML helpers have been deprecated in Laravel 5.0; however, there are community-driven replacements such as those maintained by the Laravel Collective.

For example, you may add "laravelcollective/html": "~5.0" to your composer.json file's require section.

You'll also need to add the Form and HTML facades and service provider. Edit config/app.php and add this line to the 'providers' array:

'Collective\Html\HtmlServiceProvider',

Next, add these lines to the 'aliases' array:

'Form' => 'Collective\Html\FormFacade',
'Html' => 'Collective\Html\HtmlFacade',

CacheManager

If your application code was injecting Illuminate\Cache\CacheManager to get a non-Facade version of Laravel's cache, inject Illuminate\Contracts\Cache\Repository instead.

Pagination

Replace any calls to $paginator->links() with $paginator->render().

Beanstalk Queuing

Laravel 5.0 now requires "pda/pheanstalk": "~3.0" instead of "pda/pheanstalk": "~2.1".

Remote

The Remote component has been deprecated.

Workbench

The Workbench component has been deprecated.

Upgrading To 4.2 From 4.1

PHP 5.4+

Laravel 4.2 requires PHP 5.4.0 or greater.

Encryption Defaults

Add a new cipher option in your app/config/app.php configuration file. The value of this option should be MCRYPT_RIJNDAEL_256.

'cipher' => MCRYPT_RIJNDAEL_256

This setting may be used to control the default cipher used by the Laravel encryption facilities.

Note: In Laravel 4.2, the default cipher is MCRYPT_RIJNDAEL_128 (AES), which is considered to be the most secure cipher. Changing the cipher back to MCRYPT_RIJNDAEL_256 is required to decrypt cookies/values that were encrypted in Laravel <= 4.1

Soft Deleting Models Now Use Traits

If you are using soft deleting models, the softDeletes property has been removed. You must now use the SoftDeletingTrait like so:

use Illuminate\Database\Eloquent\SoftDeletingTrait;

class User extends Eloquent {
    use SoftDeletingTrait;
}

You must also manually add the deleted_at column to your dates property:

class User extends Eloquent {
    use SoftDeletingTrait;

    protected $dates = ['deleted_at'];
}

The API for all soft delete operations remains the same.

Note: The SoftDeletingTrait can not be applied on a base model. It must be used on an actual model class.

View / Pagination Environment Renamed

If you are directly referencing the Illuminate\View\Environment class or Illuminate\Pagination\Environment class, update your code to reference Illuminate\View\Factory and Illuminate\Pagination\Factory instead. These two classes have been renamed to better reflect their function.

Additional Parameter On Pagination Presenter

If you are extending the Illuminate\Pagination\Presenter class, the abstract method getPageLinkWrapper signature has changed to add the rel argument:

abstract public function getPageLinkWrapper($url, $page, $rel = null);

Iron.Io Queue Encryption

If you are using the Iron.io queue driver, you will need to add a new encrypt option to your queue configuration file:

'encrypt' => true

Upgrading To 4.1.29 From <= 4.1.x

Laravel 4.1.29 improves the column quoting for all database drivers. This protects your application from some mass assignment vulnerabilities when not using the fillable property on models. If you are using the fillable property on your models to protect against mass assignment, your application is not vulnerable. However, if you are using guarded and are passing a user controlled array into an "update" or "save" type function, you should upgrade to 4.1.29 immediately as your application may be at risk of mass assignment.

To upgrade to Laravel 4.1.29, simply composer update. No breaking changes are introduced in this release.

Upgrading To 4.1.26 From <= 4.1.25

Laravel 4.1.26 introduces security improvements for "remember me" cookies. Before this update, if a remember cookie was hijacked by another malicious user, the cookie would remain valid for a long period of time, even after the true owner of the account reset their password, logged out, etc.

This change requires the addition of a new remember_token column to your users (or equivalent) database table. After this change, a fresh token will be assigned to the user each time they login to your application. The token will also be refreshed when the user logs out of the application. The implications of this change are: if a "remember me" cookie is hijacked, simply logging out of the application will invalidate the cookie.

Upgrade Path

First, add a new, nullable remember_token of VARCHAR(100), TEXT, or equivalent to your users table.

Next, if you are using the Eloquent authentication driver, update your User class with the following three methods:

public function getRememberToken()
{
    return $this->remember_token;
}

public function setRememberToken($value)
{
    $this->remember_token = $value;
}

public function getRememberTokenName()
{
    return 'remember_token';
}

Note: All existing "remember me" sessions will be invalidated by this change, so all users will be forced to re-authenticate with your application.

Package Maintainers

Two new methods were added to the Illuminate\Auth\UserProviderInterface interface. Sample implementations may be found in the default drivers:

public function retrieveByToken($identifier, $token);

public function updateRememberToken(UserInterface $user, $token);

The Illuminate\Auth\UserInterface also received the three new methods described in the "Upgrade Path".

Upgrading To 4.1 From 4.0

Upgrading Your Composer Dependency

To upgrade your application to Laravel 4.1, change your laravel/framework version to 4.1.* in your composer.json file.

Replacing Files

Replace your public/index.php file with this fresh copy from the repository.

Replace your artisan file with this fresh copy from the repository.

Adding Configuration Files & Options

Update your aliases and providers arrays in your app/config/app.php configuration file. The updated values for these arrays can be found in this file. Be sure to add your custom and package service providers / aliases back to the arrays.

Add the new app/config/remote.php file from the repository.

Add the new expire_on_close configuration option to your app/config/session.php file. The default value should be false.

Add the new failed configuration section to your app/config/queue.php file. Here are the default values for the section:

'failed' => [
    'database' => 'mysql', 'table' => 'failed_jobs',
],

(Optional) Update the pagination configuration option in your app/config/view.php file to pagination::slider-3.

Controller Updates

If app/controllers/BaseController.php has a use statement at the top, change use Illuminate\Routing\Controllers\Controller; to use Illuminate\Routing\Controller;.

Password Reminders Updates

Password reminders have been overhauled for greater flexibility. You may examine the new stub controller by running the php artisan auth:reminders-controller Artisan command. You may also browse the updated documentation and update your application accordingly.

Update your app/lang/en/reminders.php language file to match this updated file.

Environment Detection Updates

For security reasons, URL domains may no longer be used to detect your application environment. These values are easily spoofable and allow attackers to modify the environment for a request. You should convert your environment detection to use machine host names (hostname command on Mac, Linux, and Windows).

Simpler Log Files

Laravel now generates a single log file: app/storage/logs/laravel.log. However, you may still configure this behavior in your app/start/global.php file.

Removing Redirect Trailing Slash

In your bootstrap/start.php file, remove the call to $app->redirectIfTrailingSlash(). This method is no longer needed as this functionality is now handled by the .htaccess file included with the framework.

Next, replace your Apache .htaccess file with this new one that handles trailing slashes.

Current Route Access

The current route is now accessed via Route::current() instead of Route::getCurrentRoute().

Composer Update

Once you have completed the changes above, you can run the composer update function to update your core application files! If you receive class load errors, try running the update command with the --no-scripts option enabled like so: composer update --no-scripts.

Wildcard Event Listeners

The wildcard event listeners no longer append the event to your handler functions parameters. If you require finding the event that was fired you should use Event::firing().
