Laravel 5.5.42 is a security release of Laravel and is recommended as an immediate upgrade for all users. Laravel 5.5.42 also contains a breaking change to cookie encryption and serialization logic, so please read the following notes carefully when upgrading your application.
This vulnerability may only be exploited if your application encryption key (APP_KEY environment variable) has been accessed by a malicious user. Typically, it is not possible for users of your application to gain access to this value. However, ex-employees that had access to the encryption key may be able to use the key to attack your applications. If you have any reason to believe your encryption key is in the hands of a malicious party, you should always rotate the key to a new value.
Laravel 5.5.42 disables all serialization / unserialization of cookie values. Since all Laravel cookies are encrypted and signed, cookie values are typically considered safe from client tampering. However, if your application's encryption key is in the hands of a malicious party, that party could craft cookie values using the encryption key and exploit vulnerabilities inherit to PHP object serialization / unserialization, such as calling arbitary class methods within your application.
Disabling serialization on all cookie values will invalidate all of your application's sessions and users will need to log into the application again. In addition, any other encrypted cookies your application is setting will have invalid values. For this reason, you may wish to add additional logic to your application to validate that your custom cookie values match an expected list of values you expect; otherwise, you should discard them.
Since this vulnerability is not able to be exploited without access to your application's encryption key, we have chosen to provide a way to re-enable encrypted cookie serialization while you make your application compatible with these changes. To enable / disable cookie serialization, you may change the static serialize property of the App\Http\Middleware\EncryptCookies middleware:
/**
* Indicates if cookies should be serialized.
*
* @var bool
*/
protected static $serialize = true;
Note: When encrypted cookie serialization is enabled, your application will be vulnerable to attack if its encryption key is accessed by a malicious party. If you believe your key may be in the hands of a malicious party, you should rotate the key to a new value before enabling encrypted cookie serialization.
{note} We attempt to document every possible breaking change. Since some of these breaking changes are in obscure parts of the framework only a portion of these changes may actually affect your application.
Laravel 5.5 requires PHP 7.0.0 or higher.
Update your laravel/framework dependency to 5.5.* in your composer.json file. In addition, you should update your phpunit/phpunit dependency to ~6.0. Next, add the filp/whoops package with version ~2.0 to the require-dev section of your composer.json file. Finally, in the scripts section of your composer.json file, add the package:discover command to the post-autoload-dump event:
"scripts": {
...
"post-autoload-dump": [
"Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
"@php artisan package:discover"
],
}
If you are using the laravel/browser-kit-testing package, you should update the package to 2.* in your composer.json file.
Of course, don't forget to examine any 3rd party packages consumed by your application and verify you are using the proper version for Laravel 5.5 support.
{tip} If you commonly use the Laravel installer via
laravel new, you should update your Laravel installer package using thecomposer global updatecommand.
Laravel Dusk 2.0.0 has been released to provide compatibility with Laravel 5.5 and headless Chrome testing.
The Pusher event broadcasting driver now requires version ~3.0 of the Pusher SDK.
Laravel 5.5 requires version ~6.0 of Swift Mailer.
In Laravel 5.5, Artisan can automatically discover commands so that you do not have to manually register them in your kernel. To take advantage of this new feature, you should add the following line to the commands method of your App\Console\Kernel class:
$this->load(__DIR__.'/Commands');
fire MethodAny fire methods present on your Artisan commands should be renamed to handle.
optimize CommandWith recent improvements to PHP op-code caching, the optimize Artisan command is no longer needed. You should remove any references to this command from your deployment scripts as it will be removed in a future release of Laravel.
{note} When upgrading from Laravel 5.4 to 5.5, all
remember_mecookies will be rendered invalid and users will be logged out.
authorizeResource Controller MethodWhen passing a multi-word model name to the authorizeResource method, the resulting route segment will now be "snake" case, matching the behavior of resource controllers.
basic and onceBasic MethodsAuth::basic and Auth::onceBasic now throw \Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException rather than returning a Response when authentication fails. By default, this will still result in a 401 response being sent to the client. However, if your application logic checked the return value of Auth::basic in order to return a custom response or implement other behavior on authentication failure, you will now need to handle the UnauthorizedHttpException instead, either in a catch block or in your application's exception handler.
before Policy MethodThe before method of a policy class will not be called if the class doesn't contain a method matching the name of the ability being checked.
If you are using the database cache driver, you should run php artisan cache:clear when deploying your upgraded Laravel 5.5 application for the first time.
belongsToMany MethodIf you are overriding the belongsToMany method on your Eloquent model, you should update your method signature to reflect the addition of new arguments:
/**
* Define a many-to-many relationship.
*
* @param string $related
* @param string $table
* @param string $foreignPivotKey
* @param string $relatedPivotKey
* @param string $parentKey
* @param string $relatedKey
* @param string $relation
* @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function belongsToMany($related, $table = null, $foreignPivotKey = null,
$relatedPivotKey = null, $parentKey = null,
$relatedKey = null, $relation = null)
{
//
}
getQualifiedRelatedKeyNameThe getQualifiedRelatedKeyName method has been renamed to getQualifiedRelatedPivotKeyName.
getQualifiedForeignKeyNameThe getQualifiedForeignKeyName method has been renamed to getQualifiedForeignPivotKeyName.
is MethodIf you are overriding the is method of your Eloquent model, you should remove the Model type-hint from the method. This allows the is method to receive null as an argument:
/**
* Determine if two models have the same ID and belong to the same table.
*
* @param \Illuminate\Database\Eloquent\Model|null $model
* @return bool
*/
public function is($model)
{
//
}
$events PropertyThe $events property on your models should be renamed to $dispatchesEvents. This change was made because of a high number of users needing to define an events relationship, which caused a conflict with the old property name.
$parent PropertyThe protected $parent property on the Illuminate\Database\Eloquent\Relations\Pivot class has been renamed to $pivotParent.
create MethodsThe BelongsToMany, HasOneOrMany, and MorphOneOrMany classes' create methods have been modified to provide a default value for the $attributes argument. If you are overriding these methods, you should update your signatures to match the new definition:
public function create(array $attributes = [])
{
//
}
When deleting a "soft deleted" model, the exists property on the model will remain true.
withCount Column FormattingWhen using an alias, the withCount method will no longer automatically append _count onto the resulting column name. For example, in Laravel 5.4, the following query would result in a bar_count column being added to the query:
$users = User::withCount('foo as bar')->get();
However, in Laravel 5.5, the alias will be used exactly as it is given. If you would like to append _count to the resulting column, you must specify that suffix when defining the alias:
$users = User::withCount('foo as bar_count')->get();
To prevent accessing a model's private properties when using array access, it's no longer possible to have a model method with the same name as an attribute or property. Doing so will cause exceptions to be thrown when accessing the model's attributes via array access ($user['name']) or the data_get helper function.
In Laravel 5.5, all exceptions, including validation exceptions, are converted into HTTP responses by the exception handler. In addition, the default format for JSON validation errors has changed. The new format conforms to the following convention:
{
"message": "The given data was invalid.",
"errors": {
"field-1": [
"Error 1",
"Error 2"
],
"field-2": [
"Error 1",
"Error 2"
],
}
}
However, if you would like to maintain the Laravel 5.4 JSON error format, you may add the following method to your App\Exceptions\Handler class:
use Illuminate\Validation\ValidationException;
/**
* Convert a validation exception into a JSON response.
*
* @param \Illuminate\Http\Request $request
* @param \Illuminate\Validation\ValidationException $exception
* @return \Illuminate\Http\JsonResponse
*/
protected function invalidJson($request, ValidationException $exception)
{
return response()->json($exception->errors(), $exception->status);
}
This change also affects the validation error formatting for authentication attempts made over JSON. In Laravel 5.5, JSON authentication failures will return the error messages following the new formatting convention described above.
If you were customizing the response format of an individual form request, you should now override the failedValidation method of that form request, and throw an HttpResponseException instance containing your custom response:
use Illuminate\Http\Exceptions\HttpResponseException;
/**
* Handle a failed validation attempt.
*
* @param \Illuminate\Contracts\Validation\Validator $validator
* @return void
*
* @throws \Illuminate\Validation\ValidationException
*/
protected function failedValidation(Validator $validator)
{
throw new HttpResponseException(response()->json(..., 422));
}
files MethodThe files method of the Illuminate\Filesystem\Filesystem class has changed its signature to add the $hidden argument and now returns an array of SplFileInfo objects, similar to the allFiles method. Previously, the files method returned an array of string path names. The new signature is as follows:
public function files($directory, $hidden = false)
The unused $data and $callback arguments were removed from the Illuminate\Contracts\Mail\MailQueue contract's queue and later methods:
/**
* Queue a new e-mail message for sending.
*
* @param string|array|MailableContract $view
* @param string $queue
* @return mixed
*/
public function queue($view, $queue = null);
/**
* Queue a new e-mail message for sending after (n) seconds.
*
* @param \DateTimeInterface|\DateInterval|int $delay
* @param string|array|MailableContract $view
* @param string $queue
* @return mixed
*/
public function later($delay, $view, $queue = null);
dispatch HelperIf you would like to dispatch a job that runs immediately and returns a value from the handle method, you should use the dispatch_now or Bus::dispatchNow method to dispatch the job:
use Illuminate\Support\Facades\Bus;
$value = dispatch_now(new Job);
$value = Bus::dispatchNow(new Job);
all MethodIf you are overriding the all method of the Illuminate\Http\Request class, you should update your method signature to reflect the new $keys argument:
/**
* Get all of the input and files for the request.
*
* @param array|mixed $keys
* @return array
*/
public function all($keys = null)
{
//
}
has MethodThe $request->has method will now return true even if the input value is an empty string or null. A new $request->filled method has been added that provides the previous behavior of the has method.
intersect MethodThe intersect method has been removed. You may replicate this behavior using array_filter on a call to $request->only:
return array_filter($request->only('foo'));
only MethodThe only method will now only return attributes that are actually present in the request payload. If you would like to preserve the old behavior of the only method, you may use the all method instead.
return $request->all('foo');
request() HelperThe request helper will no longer retrieve nested keys. If needed, you may use the input method of the request to achieve this behavior:
return request()->input('filters.date');
Some authentication assertions were renamed for better consistency with the rest of the framework's assertions:
seeIsAuthenticated was renamed to assertAuthenticated.dontSeeIsAuthenticated was renamed to assertGuest.seeIsAuthenticatedAs was renamed to assertAuthenticatedAs.seeCredentials was renamed to assertCredentials.dontSeeCredentials was renamed to assertInvalidCredentials.If you are using the Mail fake to determine if a mailable was queued during a request, you should now use Mail::assertQueued instead of Mail::assertSent. This distinction allows you to specifically assert that the mail was queued for background sending and not sent during the request itself.
Laravel Tinker now supports omitting namespaces when referring to your application classes. This feature requires an optimized Composer class-map, so you should add the optimize-autoloader directive to the config section of your composer.json file:
"config": {
...
"optimize-autoloader": true
}
LoaderInterfaceThe Illuminate\Translation\LoaderInterface interface has been moved to Illuminate\Contracts\Translation\Loader.
All of the validator's validation methods are now public instead of protected.
When allowing the dynamic __call method to share variables with a view, these variables will automatically use "camel" case. For example, given the following:
return view('pool')->withMaximumVotes(100);
The maximumVotes variable may be accessed in the template like so:
{{ $maximumVotes }}
@php Blade DirectiveThe @php blade directive no longer accepts inline tags. Instead, use the full form of the directive:
@php
$teamMember = true;
@endphp
We also encourage you to view the changes in the laravel/laravel GitHub repository. While many of these changes are not required, you may wish to keep these files in sync with your application. Some of these changes will be covered in this upgrade guide, but others, such as changes to configuration files or comments, will not be. You can easily view the changes with the GitHub comparison tool and choose which updates are important to you.
