Laravel:仅当另一个通过验证规则时才应用验证规则 [英] Laravel: Apply validation rule only if the another one passed

问题描述

在我的Laravel 5.2应用程序中，我具有以下验证规则来检查字段:

In my Laravel 5.2 app, I have the following validation rules to check a field:

$rules = array(
    'file' => 'mimes:jpg,png,pdf,doc,docx',
    'file' => 'validate_file'
);

现在，validate_file是自定义验证规则.我只想仅在第一个mimes验证通过的情况下运行它.

Now, the validate_file is a custom validation rule. I want to run it only only if the first mimes validation passes.

我知道我可以简单地通过错误进行验证/重定向-分两批进行，首先是mimes，然后是validate_file，但这似乎有点过头了.

I know I could simply validate/redirect with errors - in two batches, first the mimes, then the validate_file, but it seems like an overkill.

有什么方法可以在Laravel 5.2中做到这一点吗?

Any way I can do it the smart way in Laravel 5.2?

推荐答案

使用保释"属性.第一次失败后它将停止验证.

Use "bail" attribute. It will stop validation after first failure.

$this->validate($request, [
    'title' => 'bail|mimes:jpg,png,pdf,doc,docx|validate_file',
]);
