thinkphp validate验证器自定义规则如何添加

namespace app\validate;

use think\Validate;

class UserValidate extends Validate
{
    protected $rule = [
        'phone' => 'require|mobile',
        'age'   => 'require|between:18,65',
        'code'  => 'require|checkCode',
    ];

    protected $message = [
        'phone.require' => '手机号不能为空',
        'phone.mobile'  => '请输入正确的手机号',
        'age.between'   => '年龄必须在18到65之间',
        'code.checkCode'=> '验证码格式不正确',
    ];

    // 自定义方法：检查验证码是否为6位数字
    protected function checkCode($value, $rule, $data, $field)
    {
        return preg_match('/^\d{6}$/', $value) === 1;
    }
}

$validate = new \app\validate\UserValidate();
if (!$validate->scene('register')->check($data)) {
    echo $validate->getError();
}

use think\facade\Validate;

$rule = [
    'email' => 'require|email',
    'phone' => 'require|number|length:11',
    'name'  => function ($value) {
        return strlen($value) >= 2 && strlen($value) <= 20 ? true : '姓名长度必须在2-20个字符之间';
    }
];

$data = ['name' => '小明', 'email' => 'test@example.com', 'phone' => '13800138000'];

if (!Validate::rule($rule)->check($data)) {
    echo Validate::getSceneError();
}

use think\Validate;

// 注册自定义规则
Validate::maker(function (Validate $validate) {
    $validate->extend('idCard', function($value) {
        return preg_match('/^[1-9]\d{5}(18|19|20)\d{2}((0[1-9])|(1[0-2]))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/', $value);
    }, '身份证号码格式不正确');
});

'id_card' => 'require|idCard'

protected $scene = [
    'register' => ['phone', 'code', 'age'],
    'edit'     => ['phone', 'age'],
];
