[[!if test="enabled(attachment)"
|
||
|
|
then="This wiki has attachments **enabled**."
|
||
|
|
else="This wiki has attachments **disabled**."]]
|
||
|
|
|
||
|
|
If attachments are enabled, the wiki admin can control what types of
|
||
|
|
attachments will be accepted, via the `allowed_attachments`
|
||
|
|
configuration setting.
|
||
|
|
|
||
|
|
For example, to limit most users to uploading small images, and nothing else,
|
||
|
|
while allowing larger mp3 files to be uploaded by joey into a specific
|
||
|
|
directory, and check all attachments for viruses, something like this could be
|
||
|
|
used:
|
||
|
|
|
||
|
|
virusfree() and ((user(joey) and podcast/*.mp3 and mimetype(audio/mpeg) and maxsize(15mb)) or ((mimetype(image/jpeg) or mimetype(image/png)) and maxsize(50kb)))
|
||
|
|
|
||
|
|
The regular [[ikiwiki/PageSpec]] syntax is expanded with the following
|
||
|
|
additional tests:
|
||
|
|
|
||
|
|
* "`maxsize(size)`" - tests whether the attachment is no larger than the
|
||
|
|
specified size. The size defaults to being in bytes, but "kb", "mb", "gb"
|
||
|
|
etc can be used to specify the units.
|
||
|
|
|
||
|
|
* "`minsize(size)`" - tests whether the attachment is no smaller than the
|
||
|
|
specified size.
|
||
|
|
|
||
|
|
* "`ispage()`" - tests whether the attachment will be treated by ikiwiki as a
|
||
|
|
wiki page. (Ie, if it has an extension of ".mdwn", or of any other enabled
|
||
|
|
page format).
|
||
|
|
|
||
|
|
So, if you don't want to allow wiki pages to be uploaded as attachments,
|
||
|
|
use `!ispage()` ; if you only want to allow wiki pages to be uploaded
|
||
|
|
as attachments, use `ispage()`.
|
||
|
|
|
||
|
|
* "`mimetype(foo/bar)`" - checks the MIME type of the attachment. You can
|
||
|
|
include a glob in the type, for example `mimetype(image/*)`.
|
||
|
|
|
||
|
|
* "`virusfree()`" - checks the attachment with an antiviral program.
