验证特定规则

本文介绍了验证特定规则-Laravel的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用最新的Laravel版本.

I am using latest Laravel version.

我有requests/StoreUser.php:

public function rules() { return [ 'name' => 'required||max:255|min:2', 'email' => 'required|unique:users|email', 'password' => 'required|max:255|min:6|confirmed' ]; }

用于创建用户.

现在我需要并更新用户，但是如何仅执行特定规则?

Now I need and to update the user, but how can I execute only specific rules ?

例如，如果未提供name，而仅提供了email，那么如何仅对电子邮件运行验证?

For the example, if name is not provided, but only the email, how can I run the validation only for the email ?

推荐答案

这比您想象的要容易.使规则取决于HTTP方法.这是我的工作示例.

This is easier than you thought. Make rules depend on the HTTP method. Here is my working example.

public function rules() { // rules for updating record if ($this->method() == 'PATCH') { return [ 'name' => 'nullable||max:255|min:2', // either nullable or remove this line is ok 'email' => 'required|unique:users|email', ]; } else { // rules for creating record return [ 'name' => 'required||max:255|min:2', 'email' => 'required|unique:users|email', 'password' => 'required|max:255|min:6|confirmed' ]; } }
