問題描述

假設(shè)我有兩種方法的 User 模型:

Let's say I have User model with two methods:

User.php

class User extends Eloquent
{  
    /* Validation rules */
    private static $rules = array(
        'user'  => 'unique:users|required|alpha_num',
        'email' => 'required|email'
    );

    /* Validate against registration form */
    public static function register($data)
    {
        $validator = Validator::make($data, static::$rules);
        if($validator->fails())
        {
            /*... do someting */
        }
        else
        {
            /* .. do something else */
        }
    }

    /* Validate against update form */
    public static function update($data)
    {
        $validator = Validator::make($data, static::$rules);
        if($validator->fails())
        {
            /*... do someting */
        }
        else
        {
            /* .. do something else */
        }
    }
}

我的問題:我怎樣才能讓驗(yàn)證規(guī)則成為可選的，所以即使 update() 的數(shù)據(jù)只是 email 字段，它會(huì)忽略 user 并仍然驗(yàn)證為 true.
這是可能的還是我遺漏了什么?

My question: How can I make validation rules optional, so even if data for update() would be just email field, it would ignore user and still validate to true.
Is this even possible or am I missing something?

抱歉我的英語不好.

推薦答案

不確定我的問題是否正確，但如果用戶是可選的，則應(yīng)從驗(yàn)證器中刪除必需".這樣你將有:

Not sure if I'm getting your question right but if the user is optional you should remove 'required' from the validator. This way you will have:

'user'  => 'unique:users|alpha_num',

代替:

'user'  => 'unique:users|required|alpha_num',

另一方面，我為我的模型創(chuàng)建了一個(gè)自定義方法，該方法能夠根據(jù)傳入?yún)?shù)返回自定義驗(yàn)證規(guī)則.

On the other hand I create a custom method for my models that is able to return custom validation rules depending on incoming parameters.

例如:

private function getValidationRules($rules)
{
    if ($rules == UPDATE_EMAIL)
    {
        return array('email' => 'required|email');
    } else {
        return array(
            'user'  => 'unique:users|required|alpha_num',
            'email' => 'required|email'
        );
    }
}

我想這只是個(gè)人選擇，但我發(fā)現(xiàn)從方法中獲取驗(yàn)證規(guī)則可以更好地控制我真正想要驗(yàn)證的內(nèi)容，尤其是當(dāng)您想要執(zhí)行一些高級驗(yàn)證時(shí).

I guess it's only a personal choice, but I have found that getting the validation rules from a method allows more control over what I really want to validate, especially when you want to perform some advanced validations.

希望對你有幫助.
