Enekia: Laravel Validation Rules

Intervention Validation

Intervention Validation is an extension library for Laravel's own validation system. The package adds rules to validate data like IBAN, BIC, ISBN, creditcard numbers and more.

Installation

You can install this package quick and easy with Composer.

Require the package via Composer:

$ composer require intervention/validation

Laravel integration

The Validation library is built to work with the Laravel Framework (>=7). It comes with a service provider, which will be discovered automatically and registers the validation rules into your installation. The package provides 30 additional validation rules including error messages, which can be used like Laravel's own validation rules.

use Illuminate\Support\Facades\Validator;
use Simtabi\Enekia\Laravel\Traits\Rules\CreditCard;
use Simtabi\Enekia\Laravel\Traits\Rules\HexColor;
use Simtabi\Enekia\Laravel\Traits\Rules\Username;

$validator = Validator::make($request->all(), [
    'color' => new HexColor(3), // pass rule as object
    'number' => ['required', 'creditcard'], // or pass rule as string
    'name' => 'required|min:3|max:20|username', // combining rules works as well
]);

Changing the error messages:

Add the corresponding key to /resources/lang/<language>/validation.php like this:

// example
'iban' => 'Please enter IBAN number!',

Or add your custom messages directly to the validator like described in the docs.

Standalone usage

It is also possible to use this library without the Laravel framework. You won't have the Laravel facades available, so make sure to use Simtabi\Enekia\Validator for your calls.

use Simtabi\Enekia\Validator;
use Simtabi\Enekia\Laravel\Traits\Rules\CreditCard;
use Simtabi\Enekia\Laravel\Exceptions\EnekiaException;

// use static factory method to create laravel validator
$validator = Validator::make($request->all(), [
    'ccnumber' => new CreditCard(),
    'iban' => ['required', 'iban'],
    'color' => 'required|hexcolor:3',
]);

// validate single values by calling static methods
$result = Validator::isHexcolor('foobar'); // false
$result = Validator::isHexcolor('#ccc'); // true
$result = Validator::isBic('foo'); // false

// assert single values
try {
    Validator::assertHexcolor('foobar');
} catch (EnekiaException $e) {
    $message = $e->getMessage();
}

`AuthorizedOnModelAction`

Determine if the user is authorized to perform an ability on an instance of the given model. The id of the model is the field under validation

Consider the following policy:

class ModelPolicy
{
    use HandlesAuthorization;

    public function edit(User $user, Model $model): bool
    {
        return $model->user->id === $user->id;
    }
}

This validation rule will pass if the id of the logged in user matches the user_id on TestModel who's it is in the model_id key of the request.

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\AuthorizedOnModelAction;

public function rules()
{
    return [
        'model_id' => [new AuthorizedOnModelAction('edit', TestModel::class)],
    ];
}

Optionally, you can provide an authentication guard as the third parameter.

new AuthorizedOnModelAction('edit', TestModel::class, 'guard-name')

Model resolution

If you have implemented the getRouteKeyName method in your model, it will be used to resolve the model instance. For further information see Customizing The Default Key Name

`CountryCode`

Determine if the field under validation is a valid 2 letter ISO3166 country code (example of valid country codes: GB, DK, NL).

Note that this rule require the package league/iso3166 to be installed: composer require league/iso3166

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Country;

public function rules()
{
    return [
        'country_code' => ['required', new Country()],
    ];
}

If you want to validate a nullable country code field, you can call the nullable() method on the CountryCode rule. This way null and 0 are also passing values:

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Country;

public function rules()
{
    return [
        'country_code' => [(new Country())->nullable()],
    ];
}

`Currency`

Determine if the field under validation is a valid 3 letter ISO4217 currency code (example of valid currencies: EUR, USD, CAD).

Note that this rule require the package league/iso3166 to be installed: composer require league/iso3166

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Currency;

public function rules()
{
    return [
        'currency' => ['required', new Currency()], // Must be present and a valid currency
    ];
}

If you want to validate a nullable currency field, simple do not let it be required as described in the Laravel Docs for implicit validation rules:

... when an attribute being validated is not present or contains an empty string, normal validation rules, including custom rules, are not run

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Currency;

public function rules()
{
    return [
        'currency' => [new Currency()], // This will pass for any valid currency, an empty value or null
    ];
}

`ModelsExist`

Determine if all the values in the input array exist as attributes for the given model class.

By default, the rule assumes that you want to validate using id attribute. In the example below the validation will pass if all model_ids exist for the Model.

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\ModelIdsExist;

public function rules()
{
    return [
        'model_ids' => ['array', new ModelIdsExist(Model::class)],
    ];
}

You can also pass an attribute name as the second argument. In the example below the validation will pass if there are users for each email given in the user_emails of the request.

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\ModelIdsExist;

public function rules()
{
    return [
        'user_emails' => ['array', new ModelIdsExist(User::class, 'emails')],
    ];
}

`Delimited`

This rule can validate a string containing delimited values. The constructor accepts a rule that is used to validate all separate values.

Here's an example where we are going to validate a string containing comma separated email addresses.

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Delimited;

public function rules()
{
    return [
        'emails' => [new Delimited('email')],
    ];
}

Here's some example input that passes this rule:

'[email protected], [email protected]'
''
'[email protected]'
'[email protected], [email protected], [email protected]'
' [email protected] , [email protected] , [email protected] '

This input will not pass:

'@example.com'
'[email protected] [email protected]'
'[email protected], invalid@'

Setting a minimum

You can set minimum amout of items that should be present:

(new Delimited('email'))->min(2)

'[email protected], [email protected]' // passes
'[email protected]' // fails

Setting a maximum

(new Delimited('email'))->max(2)

'[email protected]' // passes
'[email protected], [email protected], [email protected]' // fails

Allowing duplicate items

By default the rule will fail if there are duplicate items found.

'[email protected], [email protected]' // fails

You can allowing duplicate items like this:

(new Delimited('numeric'))->allowDuplicates()

Now this will pass: 1,1,2,2,3,3

Customizing the separator

(new Delimited('email'))->separatedBy(';')

'[email protected]; [email protected]; [email protected]' // passes
'[email protected], [email protected], [email protected]' // fails

Skip trimming of items

(new Delimited('email'))->doNotTrimItems()

'[email protected],[email protected]' // passes
'[email protected], [email protected]' // fails
'[email protected] , [email protected]' // fails

Composite rules

The constructor of the validator accepts a validation rule string, a validate instance, or an array.

new Delimited('email|max:20')

'[email protected]' // passes
'invalid' // fails
'[email protected]' // fails

Passing custom error messages

The constructor of the validator accepts a custom error messages array as second parameter.

// in a `FormRequest`

use Simtabi\Enekia\Laravel\Traits\Rules\Delimited;

public function rules()
{
    return [
        'emails' => [new Delimited('email', $this->messages())],
    ];
}

public function messages()
{
    return [
        'emails.email' => 'Not all the given e-mails are valid.',
    ];
}

Laravel Model Exists Rule

Laravel validation rule to check if a model exists.

You want to use this rule if the standard laravel Rule::exists('table', 'column') is not powerful enough. When you want to add joins to your exist rule, or the advanced Eloquent\Builder features like whereHas this might be for you.

Installation

You can install the package via composer:

composer require mvanduijker/laravel-model-exists-rule

Usage

Simple

<?php

use Duijker\LaravelModelExistsRule\ModelExists;
use Illuminate\Foundation\Http\FormRequest;

class ExampleUserRequest extends FormRequest
{
    public function rules()
    {
        return [
            'user_id' => [
                'required',
                new ModelExists(\App\Models\User::class, 'id'),        
            ],
        ];
    }
}

Advanced

<?php

use Illuminate\Database\Eloquent\Builder;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Validation\Rule;

class ExampleUserRequest extends FormRequest
{
    public function rules()
    {
        return [
            'user_id' => [
                'required',
                Rule::modelExists(\App\Models\User::class, 'id', function (Builder $query) {
                    $query->whereHas('role', function (Builder $query) {
                        $query->whereIn('name', ['super-admin', 'admin']);
                    });                    
                }),        
            ],
        ];
    }
}

ExtendedRFC3339

PHP doesn't validate correctly RFC3339: laravel/framework#35387

for example 2020-12-21T23:59:59+00:00 or 2020-12-21T23:59:59Z return false but it is true.

this Rule uniform the date in format: YYYY-MM-DDThh:mm:ss.mmm+nn:nn

Usage

<?php
namespace App\Api\Controllers;
use App\Http\Controllers\Controller;

use Simtabi\Enekia\Laravel\Traits\Rules\ExtendedRFC3339;

class MyController extends Controller
{
    public function index()
    {
        $myData = ['starttime' => '2022-04-06T12:00:00.123+00:00']
        Validator::make($myData, [
            'starttime'           => [new ExtendedRFC3339()],
        ])->validate();
    }
}

Laravel Profanity Validator

<?php
// ...
use Simtabi\Enekia\Laravel\Traits\Rules\Profanity;

class MyController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'username' => ['required', new Profanity()]
        ]);

        // ...
    }
}

The validator will load the default locale in your config/app.php file configuration which by is en. If your locale is not supported, please post an issue for this project

If you want to use others dictionaries you can pass them as parameters in the validator.

<?php
// ...
use Simtabi\Enekia\Laravel\Traits\Rules\Profanity;

class MyController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'username' => ['required', new Profanity('en', 'es')]
        ]);

        // ...
    }
}

You can also send as parameter a path of a file which is a dictionary in order to replace the default dictionary or add a new non supported locale.

<?php
// ...
use Simtabi\Enekia\Laravel\Traits\Rules\Profanity;

class MyController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'username' => ['required', new Profanity('en', 'es', resource_path('lang/fr/dict.php'))]
        ]);

        // ...
    }
}

Strict validation

Now you can strictly validate the exact profane word in the content.

<?php
// ...
use Simtabi\Enekia\Laravel\Traits\Rules\Profanity;

class MyController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'username' => ['required', (new Profanity())->validateStrictly(true)]
        ]);

        // ...
    }
}

Laravel Password History Validation

Usage

This package will observe the created and updated event of the models (check the config file for settings) and records the password hashes automatically.

In Your Form Request or Inline Validation, All You Need To Do Is Instantiate The Password class passing the current user as an argument

<?php
use Simtabi\Enekia\Laravel\Traits\Rules\Password;

$this->validate($request, [
            'password' => [
                'required', (new Password())->checkIfUsedBefore($request->user())
            ]
        ]);

Cleaning Up Old Record - (Optional)

Because We Are Storing The Hashed Password In Your Database, Your Database Can Get Long When You Have Lots Of Users

Add PasswordHistoryTrait To Your User Model

<?php
use Simtabi\Enekia\Laravel\Traits\HasPasswordHistory;
use Illuminate\Auth\Authenticatable;

class User extends Authenticatable
{
    use Notifiable, HasPasswordHistory;

}

Then You Can Run The Following Artisan Command

php artisan enekia:password-history:clear
