Composite Unique Validator

A muti-column unique validation extension with exception for Laravel 5.*

Installation

Install the package through Composer.

On you project directory run the composer require command from the Terminal:

composer require ahkmunna/composite-unique-validator

Now add the service provider to your config/app.php file. Add this line to the providers array:

ahkmunna\validator\CompositeUniqueValidatorServiceProvider::class

##Translations Run this command to move the translation file

php artisan vendor:publish

##Error messages Add this method in your validation request class

public function messages()
{
    return [
        'email.composite_unique' => trans('compositeUniqueValidator::compositeUniqueValidator.composite_unique'),
    ];
}

Now you're ready to start using the validator in your application.

###Use case 1 Like any laravel validation rules:

$rules = array(
    'field_name' => 'composite_unique:table, unique_column_1, unique_column_2, unique_column_3',
);

###Use case 2 Pass a value or Check uniqueness with a field that not in current form request:

$rules = array(
    'field_name' => 'composite_unique:table, unique_column_1, unique_column_2:4, unique_column_3',
);

unique_column_2 is passed with a value so the validator will ignore the form request value and compare the field with the given value, It is useful sometimes, you can give a field name that not exist in the form request but in the database table.

###Use case 3: Check uniqueness with exception:

$rules = array(
    'field_name' => 'composite_unique:table, unique_column_1, unique_column_2, unique_column_3, 1',
);

The last parameter is a primary key of the table that row will be ignored. Useful for update operation.
