A Laravel Validation Rule that helps catch profanity in your application.
Squeaky (short for Squeaky Clean) is a Laravel validation rule that you can add your Laravel application, to ensure any
user submitted input such as a name or biography, is free of profanity and therefore, clean. Just add new Clean() to
your rules and you're good to go!
Squeaky is powered by Profanify, which is a PestPHP Plugin that does the same thing, but for code. By utilising the profanity in that package, Squeaky is powerful from the get-go and provides support for numerous locales, not just English.
To install Squeaky, you can run the following command in your project's root:
composer require jonpurvis/squeaky
Let's take a look at how Squeaky works. As it's a Laravel Validation rule, there's not really that much to it. You would use it in the same way you would use a custom validation rule you've added yourself.
Let's take the following scenario where we have a form that allows a user to enter their name, email and bio:
use App\Models\User;
use Illuminate\Validation\Rule;
use JonPurvis\Squeaky\Rules\Clean;
return [
'name' => ['required', 'string', 'max:255', new Clean],
'email' => [
'required',
'string',
'lowercase',
'email',
'max:255',
Rule::unique(User::class)->ignore($this->user()->id),
],
'bio' => ['required', 'string', 'max:255', new Clean],
];You'll notice that both name and bio are using the Clean rule. This rule will take the value and ensure that
it doesn't exist in the profanity config files that the package has. By default, it will use your app locale, so if
your locale is set to en, it will scan profanity in the en profanity config.
If profanity is found, an error will appear in the validation errors array and will be shown to your user (if your application does this).
Some applications allow for more than one language, so you're able to pass in additional locales to the rule to cater
for them. Below is an example showing how to cater for both en and it:
use JonPurvis\Squeaky\Rules\Clean;
'name' => ['required', 'string', 'max:255', new Clean(['en', 'it'])],Alternatively, instead of passing an array of strings to the rule, you can pass in an array of JonPurvis\Squeaky\Enums\Locale enums to specify the locales:
use JonPurvis\Squeaky\Enums\Locale;
use JonPurvis\Squeaky\Rules\Clean;
'name' => ['required', 'string', 'max:255', new Clean([Locale::English, Locale::Italian])],This will then check the locale config for any locale you've passed in (providing the config exists!). If profanity is found in any of them, an error will appear in the validation errors.
The really cool thing about this, is the error will be returned in the language that failed. So if the failure was
found in the it profanity list, the package assumes the user is Italian and returns the error message in Italian to
let them know that their value is not clean.
Squeaky currently supports the following languages:
- English
- Italian
- Arabic
- Portuguese
- Dutch
Contributions to the package are more than welcome! Depending on the type of change, there's a few extra steps that will need carrying out:
These changes should be done in Profanify and a new release should be tagged. Dependabot will then open a PR on this repo. Once that's been merged, it should be good to go because the config will already be getting loaded.
The new locale config will need adding to Profanify first and a new release
should be tagged. Dependabot will then open a PR on this repo. Additionally, the new config will need loading in
within the boot method of the service provider of this package.
A new case will also need adding to the JonPurvis/Squeaky/Enums/Locale enum to support the new locale.
For changes to how this rule works, these should be done in this package. No change needed to Profanify.
