如何在Laravel中验证文件类型 [英] How to validate a file type in laravel

问题描述

我需要验证用户仅上传.jpg

I need to validate that a user only uploads a .jpg

我有以下请求类.我将图片设为必填项，但不知道如何检查是否只有.jpg

I have the following request class. I made the image required but don't know how to check that it is only .jpg

public function rules()
{
    return [
        'name' => 'required|min:3',
        'sku' => 'required|min:5|unique:products',
        'description' => 'required|min:20',
        'price' => 'required',
        'image' => 'required'
    ];
} 

推荐答案

是否必须只是.jpg?如果是这样，则类似:

Does it have to just be .jpg? If so then something like:

'image' => 'required|mimes:jpeg'

如果它可以是任何类型的图像，则:

If it can be any type of image, then:

'image' => 'required|image'
