wp_count_attachments ( $mime_type = '' )
- (string|array) $mime_type Optional. Array or comma-separated list of MIME patterns. Default empty.
- (object) An object containing the attachment counts by mime type.
- Introduced in WordPress: 2.5.0
- Deprecated in WordPress: —
Count number of attachments for the mime type(s).
If you set the optional mime_type parameter, then an array will still be
returned, but will only have the item you are looking for. It does not give
you the number of attachments that are children of a post. You can get that
by counting the number of children that post has.
