安装

composer require illuminate/validation

引入提示消息

项目根目录创建 lang/zh_cn/validation.php 文件

<?php

return [

封装 handler

封装 handler

• $translation_path 定位到刚刚创建的 lang 目录
• $translation_locale 为多语言目录名，即 zh_cn

namespace App\\handlers;


class Validator extends \\Illuminate\\Validation\\Factory
{
    /***
     * 创建实例
     *
     * @return \\Illuminate\\Validation\\Factory
     */

    public static function getInstance()
    {
        static $validator = null;
        if ($validator === null) {
            $translation_path = __DIR__ . \'/../lang\';
            $translation_locale = \'zh_cn\';
            $translation_file_loader = new \\Illuminate\\Translation\\FileLoader(new \\Illuminate\\Filesystem\\Filesystem,
                $translation_path);
            $translator = new \\Illuminate\\Translation\\Translator($translation_file_loader, $translation_locale);
            $validator = new \\Illuminate\\Validation\\Factory($translator);
        }
        return $validator;
    }
}

使用

直接使用

// 接参
$data[\'title\']      =  \'123\';
$data[\'content\']    = \'123\';

// 验证
$validator = Validator::getInstance()->make($data, [
    \'title\' => \'required|min:10\',
    \'content\' => \'required|min:10\',
]);

自定义消息提示和定义属性名称

// 接参
$data[\'title\']      =  \'123\';
$data[\'content\']    = \'123\';

// 规则
$rules = [
    \'title\' => \'required|min:10\',
    \'content\' => \'required|min:10\',
];
// 自定义消息提示
$messages = [
    \'title.required\' => \':title字段必须\'
];
//属性名称
$attributes = [
    \'title\' => \'标题\',
    \'content\' => \'内容\',
];
// 验证
$validator = Validator::getInstance()->make($data, $rules, $message, $attributes);

打印错误消息

if ($validator->fails()) {
    print_r($validator->errors()->all());
}

PS：验证规则请前往 Laravel Validator 文档查看

finish!
