README

You have some input data to validate but you don't want to grab the huge libraries to validate them? Well here is the solution, PHPValidate is a very light libraries that allows you to validate simple data and enables you to create custom constraint at any time! Come on give it a try!

Installation

composer require inani/phpvalidate 

Usage

Feed the Validator with the array data to verifies

$validator = new Validator([  'name' => 'Inani El Houssain']);

Build your Rules

// Only if required and without length greater or equal than 10 characters
$validator->addRule(( new Rule('name'))->required()->min(10));

Check the rules

$bool = $validator->check();

Get the errors list

// get the errors of the name field, all the fields if not specified
$validator->getErrors('name');

Available rules

rule	README
required	Field not empty
min	The minimum characters
max	The maximum number of characters
number	the input should be a numeric value

Custom Constraints

Every custom rule should extends the CustomConstraint Class and implements the two methods, for instance creating a rule that validates an email field:

<?php
use Inani\PHPValidate\CustomConstraint;

class ShouldBeAnEmail extends CustomConstraint
{
  /**
   * Check if the field is Required
   *
   * @param null $value
   * @return bool
   */
  public function isValid($value = null)
  {
    if(!filter_var($value, FILTER_VALIDATE_EMAIL)){

      $this->errorFound();

      return false;
    }

    return true;
  }

  public function getError()
  {
    return "This is not a valid email";
  }
}

And its usage is as simple as injecting the Rule in the rules array like this :

$validator->addRule(( new Rule('email'))->required()->inject(new ShouldBeAnEmail));
