在Symfony2中上传文件时设置文件类型

Question

So I have the file upload working well. However I need to set type of file that is allowed, where and how do I set the type of file that can be uploaded. It's supposed to be an image file, and I don't want users (obviously) uploading anything but an image. I would assume it's somewhere in validation.yml?

Thank you!

Answer 1

There are two ways, or using the file validation attribute, or the image validation attribute, this last as the accepted mime types as image/*

The examples on the site goes as followed:

# src/Acme/BlogBundle/Resources/config/validation.yml
Acme\BlogBundle\Entity\Author:
    properties:
        bioFile:
            - File:
                maxSize: 1024k
                mimeTypes: [application/pdf, application/x-pdf]
                mimeTypesMessage: Please upload a valid PDF

# src/Acme/BlogBundle/Resources/config/validation.yml
Acme\BlogBundle\Entity\Author
    properties:
        headshot:
            - Image:
                minWidth: 200
                maxWidth: 400
                minHeight: 200
                maxHeight: 400
