4 else="This wiki has attachments **disabled**."]]

6 If attachments are enabled, the wiki admin can control what types of

7 attachments will be accepted, by entering a [[ikiwiki/PageSpec]] in the

8 "Allowed Attachments" field of their preferences page.

10 For example, to limit arbitrary files to 50 kilobytes, but allow

11 larger mp3 files to be uploaded by joey, a something like this could be

12 used:

14 (user(joey) and *.mp3 and mimetype(audio/mpeg) and maxsize(15mb)) or (!ispage() and maxsize(50kb))

16 The regular [[ikiwiki/PageSpec]] syntax is expanded with thw following

17 additional tests:

19 * maxsize(size)

21 Tests whether the attachment is no larger than the specified size.

22 The size defaults to being in bytes, but "kb", "mb", "gb" etc can be

23 used to specify the units.

25 * minsize(size)

27 Tests whether the attachment is no smaller than the specified size.

29 * ispage()

31 Tests whether the attachment will be treated by ikiwiki as a wiki page.

32 (Ie, if it has an extension of ".mdwn", or of any other enabled page

33 format).

35 So, if you don't want to allow wiki pages to be uploaded as attachments,

36 use `!ispage()` ; if you only want to allow wiki pages to be uploaded

37 as attachments, use `ispage()`.

39 * user(username)

41 Tests whether the attachment is being uploaded by a user with the

42 specified username. If openid is enabled, an openid can also be put here.

44 * ip(address)

46 Tests whether the attacment is being uploaded from the specified IP

47 address.

49 * mimetype(foo/bar)

51 This checks the MIME type of the attachment. You can include a glob

52 in the type, for example `mimetype(image/*)`.
