laravel-自定义验证

1.创建规则对象
php artisan make:rule IdCard

2.编写验证规则

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class IdCard implements Rule
{
    /**
     * Create a new rule instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Determine if the validation rule passes.
     *
     * @param string $attribute
     * @param mixed $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        return $this->validation_filter_id_card($value);
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return '证件号格式有误';
    }

3.验证器中使用

'id_card'             => ['required', new IdCard()],
