php - 拉拉维尔 : Group existing validation rules in single custom Rule?

Question

是否可以在自定义规则中使用现有的 Laravel 验证规则？

示例:required|string|max:100 我只想将这些规则分组到一个规则 custom_rule_name 中。

无论是这样

Validator::extend('foo', function ($attribute, $value, $parameters, $validator) {
    return $value == 'required|string|max:100';//something like this
});

或

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class Uppercase implements Rule
{
    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        return $value == 'required|string|max:100';//something like this
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return 'The :attribute must be uppercase.';
    }
}

请告诉我是否有可能？

谢谢

您可以在 passes() 函数内使用 Validator 外观。像这样:

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;
use Illuminate\Support\Facades\Validator;

class Uppercase implements Rule
{
    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        $validator = Validator::make([$attribute => $value], [
            $attribute => 'required|string|max:100',
        ]);

        return !$validator->fails();
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return 'The :attribute must be uppercase.';
    }
}
