Mime type for file uploads

I am using ACF to add a custom file attachment (returning the file object) to my posts. The data returned using get_field() is rather limited.

(
    [id] => 218
    [alt] => 
    [title] => PRESENTATION
    [caption] => 
    [description] => 
    [url] => http://localhost/path/to/file.doc
)

If I do a wp_query against the post I can retrieve all of the details by inspecting the attachments array:

{
    "id": 218,
    "url": "http:localhost/path/to/file.ppt",
    "slug": "presentation",
    "title": "PRESENTATION",
    "description": "",
    "caption": "",
    "parent": 217,
    "mime_type": "application/vnd.ms-powerpoint"
}

I would rather not make a new WP_Query since I am in the_loop at the time I need access to this data. Is there any ACF way of getting the mimetype associated with a file upload?

Hi @oravecz

Thanks for the question.

Currently, ACF does not return the mime type, however, this seems like a good idea.

Can you list any other attributes you would like the file type to return?

Thanks

Well, mime_type is the one I was interested in. In WordPress’s normal media/attachment workings there is additional metadata stored if the item is a video file or image file.

Hi @oravecz

Just wanted to let you know that mime_type has now been added to the image and file return data!

I’ll take a look at the read_metadata functions. They looks pretty interesting!

Thanks
