本篇文章给大家带来的内容是关于laravel中validator的使用方法介绍（代码示例），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
web 开发过程中经常会需要进行参数验证，laravel 中我们常用 validator 或者 request 这两种方法来进行验证，但是这两种验证都不是很方便进行自定义提示信息，自定义验证规则，所以下面来介绍一种很方便的用法：
新建抽象类
<?php
namespace App\Http\Validators;
use Validator;
abstract class AbstractValidator
{
/**
* Validator
*
* @var \Illuminate\Validation\Factory
*/
protected $validator;
/**
* Validation data key => value array
*
* @var array
*/
protected $data = array();
/**
* Validation errors
*
* @var array
*/
protected $errors = array();
/**
* Validation rules
*
* @var array
*/
protected $rules = array();
/**
* Validation messages
*
* @var array
*/
protected $messages = array();
/**
* Validation codes
*
* @var array
*/
protected $codes = array();
public function __construct(array $data)
{
$this->data = $data;
$this->before();
$this->validator = Validator::make($this->data, $this->rules, $this->messages);
$this->after();
}
/**
* Set data to validate
*
* @return validator
*/
public function getValidator()
{
return $this->validator;
}
/**
* Set data to validate
*
* @return $this
*/
public function with(array $data)
{
$this->data = $data;
$this->before();
$this->validator = $this->validator->make($this->data, $this->rules, $this->messages);
$this->after();
return $this;
}
/**
* Validation passes or fails
*
* @return boolean
*/
public function passes()
{
if ($this->validator->fails()) {
$this->errors = $this->validator->messages();
return false;
}
return true;
}
/**
* Return errors, if any
*
* @return array
*/
public function errors()
{
return $this->errors;
}
/**
* Return errors codes, if any
*
* @return array
*/
public function getCodes()
{
return $this->codes;
}
/**
* getRules
*
* @return array
*/
public function getRules()
{
return $this->rules;
}
/**
* getData
*
* @return array
*/
public function getData()
{
return $this->data;
}
/**
* getErrors
*
* @return array
*/
public function getErrors()
{
return $this->errors;
}
/**
* getMessages
*
* @return array
*/
public function getMessages()
{
return $this->messages;
}
/**
* setRule
*
* @param string $key
* @param string $value
*
* @return $this
*/
public function setRule($key, $value)
{
$this->rules[$key] = $value;
return $this;
}
/**
* emptyRules
*
* @return $this
*/
public function emptyRules()
{
$this->rules = array();
return $this;
}
/**
* sometimes
*
* @param string $attribute
* @param string array $rules
* @param callable $callback
*
* @return $this
*/
public function sometimes($attribute, $rules, callable $callback)
{
$this->validator->sometimes($attribute, $rules, $callback);
return $this;
}
/**
* resolver
*
* @param Closure $resolver
*
* @return $this
*/
public function resolver(Closure $resolver)
{
Validator::resolver($resolver);
return $this;
}
/**
* replacer
*
* @param Closure $resolver
*
* @return $this
*/
public function replacer($replace, Closure $resolver)
{
Validator::replacer($replace, $resolver);
return $this;
}
/**
* extendImplicit
*
* @param Closure $resolver
*
* @return $this
*/
public function extendImplicit($extendImplicit, Closure $resolver)
{
Validator::extendImplicit($extendImplicit, $resolver);
return $this;
}
/**
* extend
*
* @param string $rule
* @param \Closure string $extension
* @param string $message
*
* @return $this
*/
public function extend($rule, $extension, $message = null)
{
Validator::extend($rule, $extension, $message);
return $this;
}
/**
* before (extend(),resolver())
*
* @return $this
*/
public function before()
{
}
/**
* after(sometimes())
*
* @return $this
*/
public function after()
{
}
}
