Laravel 提供了许多有用的验证规则；同时也支持自定义规则。在服务容器中使用注册自定义验证规则：
Laravel 自定义规则实现手机号、身份证号、密码强度的验证
定义验证规则，在创建文件app\Providers\Traits\ValidatorTrait.php
<?php
namespace App\Providers\Traits;
use Illuminate\Support\Facades\Validator;
trait ValidatorTrait
{
public function validatorBoot()
{
//扩展验证规则
//验证手机号
Validator::extend('phone', function ($attribute, $value, $parameters, $validator) {
$pattern = '/^1[3456789]{1}\d{9}$/';
$res = preg_match($pattern, $value);
return $res > 0;
});
Validator::replacer('phone', function ($message, $attribute, $rule, $parameters) {
return $message;
//return str_replace($attribute,$rule,$message);
});
//验证身份证号
Validator::extend('identityCard', function ($attribute, $value, $parameters, $validator) {
return $this->checkIdentityCard($value);
});
Validator::replacer('identityCard', function ($message, $attribute, $rule, $parameters) {
return $message;
//return str_replace($attribute,$rule,$message);
});
//验证密码长度及强度.三个参数:最小长度,最大长度,密码强度1-4
Validator::extend('myPassword', function ($attribute, $value, $parameters, $validator) {
return $this->checkPassword($value, $parameters);
});
Validator::replacer('myPassword', function ($message, $attribute, $rule, $parameters) {
return $message;
});
}
/**
* 验证身份证
* @param $idCard
* @return bool
* @author code.cent123.com
* @date 2020/5/1
*/
public static function checkIdentityCard($idCard)
{
// 只能是18位
if (strlen($idCard) != 18) {
return false;
}
// 取出本体码
$idcard_base = substr($idCard, 0, 17);
// 取出校验码
$verify_code = substr($idCard, 17, 1);
// 加权因子
$factor = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2);
// 校验码对应值
$verify_code_list = array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2');
// 根据前17位计算校验码
$total = 0;
for ($i = 0; $i < 17; $i++) {
$total += substr($idcard_base, $i, 1) * $factor[$i];
}
// 取模
$mod = $total % 11;
// 比较校验码
if ($verify_code == $verify_code_list[$mod]) {
return true;
} else {
return false;
}
}
/**
* 验证密码
* @param $password
* @param $parameters
* @return bool
* @author code.cent123.com
* @date 2020/5/1
*/
public static function checkPassword($password, $parameters)
{
$pwd_len = strlen($password);
if ($pwd_len > $parameters[1] || $pwd_len < $parameters[0]) {
return false;
}
//1) 是否包含小写字母
$pattern = '/[a-z]+/';
$res = preg_match($pattern, $password);
//2) 是否包含大写字母
$pattern = '/[A-Z]+/';
$res2 = preg_match($pattern, $password);
//3) 是否包含数字
$pattern = '/\d+/';
$res3 = preg_match($pattern, $password);
//4) 是否包含特殊符号
$pattern = '/[\!\@\#\$\%\^\&\*\(\)\_\+\-\=\;\:\"\'\|\\\<\>\?\/\.\,\`\~]+/';
$res4 = preg_match($pattern, $password);
$sum = $res + $res2 + $res3 + $res4;
return $sum >= $parameters[2];
}
}2.在app\Providers\AppServiceProvider.php引入Trait
<?php
namespace App\Providers;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;
class AppServiceProvider extends ServiceProvider
{
use \App\Providers\Traits\ValidatorTrait;
/**
* Register any application services.
*
* @return void
*/
public function register()
{
Schema::defaultStringLength(191);
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
//扩展验证规则 code.cent123.com
$this->validatorBoot();
}
}3.语言文件resources\lang\zh-CN\validation.php 注意驼峰命名和下划线的转换
//自定义验证规则 code.cent123.com 'phone' => ':attribute 不符合规范', 'identity_card' => ':attribute 不符合要求', 'my_password' => ':attribute 不符合要求',
4.使用，可以和Laravel的验证规则一起
$rules = [ 'user_name' => 'required|bewteen:4,8', 'user_password' => 'required|myPassword:6,16,2', 'user_phone' => 'required|phone', 'user_identityCard' => 'identityCard', ];
