1.关于Illuminate/Validation验证器
Validation 类用于验证数据以及获取错误消息。
github地址：github.com/illuminate/validation
文档地址：https://docs.golaravel.com/docs/4.1/validation/
2.使用composer
如何使用composer：composer使用
packagist:https://packagist.org/package…
composer.json:
{
"require": {
"illuminate/validation": "^5.5"
}
}
3.将vendor引入，自定义类
<?php
/**
* Created by PhpStorm.
* User: Richard
* Date: 2017/11/28
* Time: 10:57
*/
namespace Rester;
class Validator extends \Illuminate\Validation\Factory
{
private static $message = 'ok';
private static $headers =
[
'e' => 'rules/data is empty',
'na' => 'rules/data is not a array'
];
/***
* 创建实例
*
* @return \Illuminate\Validation\Factory
*/
public static function getInstance()
{
static $validator = null;
if ($validator === null) {
$test_translation_path = __DIR__.'/lang';
$test_translation_locale = 'en';
$translation_file_loader = new \Illuminate\Translation\FileLoader(new \Illuminate\Filesystem\Filesystem, $test_translation_path);
$translator = new \Illuminate\Translation\Translator($translation_file_loader, $test_translation_locale);
$validator = new \Illuminate\Validation\Factory($translator);
}
return $validator;
}
/**
* @param array $rules 验证规则
* @param array $data 验证数据
* @return bool
*/
public static function validators($rules=[],$data=[])
{
if( empty($rules) || empty($data) )
{
self::$message = self::$headers['e'];
return false;
}
if(is_array($rules) && is_array($data))
{
$v = self::vmake($rules,$data);
if( $v->fails() )
{
self::$message = $v->messages();
return false;
}
return true;
}
self::$message = self::$headers['na'];
return false;
}
/**
* 验证实例
* @param $rules
* @param $data
* @return \Illuminate\Validation\Validator
*/
private static function vmake($rules,$data)
{
$v = self::getInstance()->make($data,$rules);
return $v;
}
/**
* 获取错误消息
* @return string
*/
public static function getMessage()
{
return self::$message;
}
}
4.在项目中引入自定义类，调用验证
//验证数据demo
public function insert()
{
//验证数据
$data = [
'name' => '1'
];
//验证规则
$rules = [
'name' => 'required|string|min:2|max:5',
];
if (Rester\Validator::validators($rules,$data)) {
echo 'ok';
}else{
echo Rester\Validator::getMessage();
}
}
