Installation & Setup

Composer

You can install this package via Composer by running the command: composer require "two_bros/validation-service:~1.0".

Or by adding the package to your composer.json

    {
        "require": {
            "two_bros/validation-service": "~1.0"
        }
    }

Then install it via composer install or composer update

Configuration

Once you have installed the package, you will need to register the Service Provider in your config/app.php under the providers array:

    'providers' => [
        ...
        TwoBros\ValidationService\Providers\ValidationServiceProvider::class,
    ];

After adding the Service Provider to your config/app.php, you should publish the configuration from the package using: php artisan vendor:publish

This will create a file named validation_service.php in the configuration directory. This file will be utilized to add any custom validation rules you may create.

The format for this configuration file is:

    return [
        'passwordStrength' => 'User@passwordStrength'
    ];

Basic Usage

Simple Validation

For each model that you need to validate, you can simply create a validation class and extend the TwoBros\ValidationService\Services\Validation\LaravelValidator.

    use TwoBros\ValidationService\Services\Validation\LaravelValidator;
    
    class ModelCreateValidator extends LaravelValidator
    {
        protected $rules = [
            'name' => 'required|min:8'
        ];
        
    }

Now when you want to validate data, you can pass the data into the validator and determine if it passed or not.

    $modelValidator = new ModelCreateValidator($this->app['validator']);
    
    if ($modelValidator->with($inputArray)
                       ->passes()) {
        // Do some stuff for passing
    } else {
        // Get the errors
        $validationErrors = $modelValidator->errors();
        
        // Do some stuff for failing
    }

Custom Messages

If you want customize your validation messages, you can do this by passing the message array to the with method.

    $messages = [
        'required' => 'The field :attribute is required'
    ];
    
    $modelValidator = new ModelCreateValidator($this->app['validator']);
    
    if ($modelValidator->with($inputArray, $messages)
                       ->passes()) {
        // Do some stuff for passing
    } else {
        // Get the errors
        $validationErrors = $modelValidator->errors();
        
        // Do some stuff for failing
    }            

Or by using the withMessages method of the validator.

    $messages = [
        'required' => 'The field :attribute is required'
    ];
    
    $modelValidator = new ModelCreateValidator($this->app['validator']);
    
    if ($modelValidator->with($inputArray)
                       ->withMessages($messages)
                       ->passes()) {
        // Do some stuff for passing
    } else {
        // Get the errors
        $validationErrors = $modelValidator->errors();
        
        // Do some stuff for failing
    }

Adding Uniqueness Requirements to Validation

There are times when you may want to use uniqueness, but when you are doing an update you need to use the id of current record to exclude the current record from the uniqueness check.

For this, you need to add a method to your validator class addRuntimeValidationRules that updates the rules with the ids needed.

    use TwoBros\ValidationService\Services\Validation\LaravelValidator;
    
    class ModelCreateValidator extends LaravelValidator
    {
        protected $rules = [
            'name' => 'required|min:8',
            'email' => 'required|max:100|unique:users,email'
        ];
        
        public function addRuntimeValidationRules()
        {

            $this->rules[ 'email' ] = 'required|max:100|unique:users,email,' . $this->uniqueIds[ 'email' ];

            return $this;
        }
    }

You can then add the function to the call string, so you can customize this with the id needed upon validation.

    $modelValidator = new ModelCreateValidator($this->app['validator']);
    
    if ($modelValidator->with($inputArray)
                       ->setUniqueId('email', $modelToUpdate->id)
                       ->addRuntimeValidationRules()
                       ->passes()) {
        // Do some stuff for passing
    } else {
        // Get the errors
        $validationErrors = $modelValidator->errors();
        
        // Do some stuff for failing
    }

You will note that you must use the setUniqueId method call to set the id of the current record. Also, instead of instantiating the validator class, you can use Laravel's IoC to bring it into the method.

    public function update(ModelValidator $modelValidator) {

        if ($modelValidator->with($inputArray)
                           ->setUniqueId('email', $modelToUpdate->id)
                           ->addRuntimeValidationRules()
                           ->passes()) {
            // Do some stuff for passing
        } else {
            // Get the errors
            $validationErrors = $modelValidator->errors();
            
            // Do some stuff for failing
        }

    }
