thinkphp 二次开发

// 创建一个新的验证规则
namespace app\common\validate;

use think\Validate;

class MyValidate extends Validate
{
    protected $rule = [
        'name' => 'require|max:25',
        'age'  => 'number|between:1,120',
    ];

    protected $message = [
        'name.require' => '名称必须',
        'name.max'     => '名称最多不能超过25个字符',
        'age.number'   => '年龄必须是数字',
        'age.between'  => '年龄只能在1-120之间',
    ];
}

return [
    // 其他配置...
    'validate' => [
        'my_validate' => app\common\validate\MyValidate::class,
    ],
];

namespace app\index\controller;

use think\Controller;
use app\common\validate\MyValidate;

class Index extends Controller
{
    public function index()
    {
        $validate = new MyValidate();
        if (!$validate->check(['name' => 'thinkphp', 'age' => 10])) {
            return $validate->getError();
        }
        return '验证通过';
    }
}
