Validation

Provides a base class to implement validation as a service., _(*1)

BaseValidator

Extend the BaseValidator to create your own validation classes., _(*2)

use Iyoworks\Validation\BaseValidator;

class FieldValidator extends BaseValidator{

    protected $rules = [
    'name' => 'required',
    'handle' => 'required|unique:fields,handle',
    'fieldtype' => 'required',
    'id' => 'exists:fields,id'
    ];

    //executed before validation
    protected function preValidate() {
        if($fieldtype = $this->get('fieldtype'))
        {
            $this->runner->addDynamic('fieldtype', 'exists', function($value){
              return app('fieldtypes')->exists($value);
            }, 'Invalid fieldtype given for :attribute attribute');
        }
    }

    //executed before validation on insert mode 
    protected function preValidateOnInsert() {}

    //executed before validation on update mode
    protected function preValidateOnUpdate() {
        if($this->get('handle'))
            $this->setUnique('handle'); // the id will be appended to the rule
    }

    //executed before validation on delete mode
    protected function preValidateOnDelete() {}
}

Next instantiate your validator, _(*3)

$validator = new FieldValidator;

$data = ['name' => 'Title', 'order' => 2];

//set the mode and pass your data object
if($validator->validForInsert($data)){
    //your logic
} else {
    $this->errors = $this->validator->errors();
    //more logic
}
