Mime Type Class

Calling the Mime Type Class

class Mime_type

ExpressionEngine uses the Mime Type class whenever a file’s, or buffer’s, Mime type needs to be determined. Additionally, it is used to dertermine if a file is an image, and to determine if a file is safe for uploading. This class is a library, so you have to load the Mime Type library before using it:

ee()->load->library('mime_type');

Note: The Mime Type library uses the Mime Type at system/ee/legacy/config/mimes.php when determining if a file is safe for uploading or is an image.

Note: There is a mime_whitelist_additions config override for adding installation specific Mime Types to the allow list.

Note: There is a mime_whitelist_member_exception config override and a mime_whitelist_member_group_exception config override which will bypass the whitelist for those members and/or member roles.
