validation

light validator

Install

composer require flatphp/validation

Usage

use \Flatphp\Validation\Validator;

// data value
$data = ['username' => 'tom', 'email' => '', 'password' => '', 'age' => 10];

// validate rules (验证规则和错误消息)
$rules = array(
    'username' => ['required|length:3,20', array('required' => 'username required', 'length' => 'length range 3-20')],
    'email' => ['email', 'invalid email'],
    'password' => 'required'
);

// validate
$res = Validator::validate($data, $rules, $failed);

// if failed echo failed message
if (!$res) {
    echo $failed['msg'];
}


// failed is referenced value if fail, format: ['on' => 'required', 'msg' => 'username required']

failed referenced value $failed 格式

// failed e.g.
array(
    'on' => 'required',
    'msg' => 'username required'
)

single value validate

use \Flatphp\Validation\Validator;
$value = 'hello';
$res = Validator::validateOne($value, 'required|length:2,20', array(
    'required' => 'cannot be empty',
), $failed);

simple use

$res = Validator::isEmail('test@gmail.com');

How to custom your own validate method 加入定制自己的验证方法

• Just extends Validator class and add your own method (继承)
• Or Just write global function (写全局函数) notes: method|function should be like isXxx($value) or isXxx($value, $params), example:
  方法或函数格式必须是这样的，参考以下：

function isZero($value)
{
    return $value === 0;
}

function isHasstr($value, $param)
{
    return strpos($value, $param) !== false;
}
