Example: Orphan Media detection
Use this plugin to find orphan and missing media files within your DokuWiki. There are 4 options provided to get the related information.
OrphanMedia show which medias are:
Option | Output |
all | will display the complete set of results of the other parameters togethers |
summary | Counter based information:
# of Page files
# of Media files
# of Media references
→ Filter settings
# of valid, qualified references
# of valid, relative references
# of Missing media files
# of Orphan media files |
valid | all valid media links referenced by full qualified path will be displayed |
relative | all valid media links referenced by relative path will be displayed |
missing | Missing Media, the media file does not exist, but there are link(s) to it elsewhere on the pages |
orphan | Orphan Media, the media file exists, but not linked and wasting space only |
Basic usage is to place one of the following six syntax lines into the page markup of a page with Admin/Superuser ACL:
====== Orphan Media detection ======
~~NOCACHE~~
~~ORPHANMEDIA:all~~
~~ORPHANMEDIA:summary~~
~~ORPHANMEDIA:valid~~
~~ORPHANMEDIA:relative~~
~~ORPHANMEDIA:missing~~
~~ORPHANMEDIA:orphan~~
The summary will be displayed in any case. Do not forget the NOCACHE to prevent cahing issues.
You can combine outputs. For instance you want to see the summary, missing and orphan option only
the following syntax is valid (put the options together without delimiter):
~~ORPHANMEDIA:missingorphan~~
Further you can specify a filter to limit the output to then specified file-extension according
following example (add file-extensions separated by ”:”):
~~ORPHANMEDIA:all:png:jpg:gif~~
The summary counters will be affected accordingly beside the limited output.
It does also check for flashplayer-plugin links if they refer to local path.
Windows-shares in test
Test Entry
The following links are just to viaualize the work of flashplayer and windows shares:
Flashplayer with options: <flashplayer width=610 height=480>file=/doku/_media/foo/bar+option.flv&autostart=true</flashplayer>
Flashplayer without options: <flashplayer width=610 height=480>file=/doku/_media/foo/bar.flv</flashplayer>
-
windows share with title:
this
two media links side by side (missing media):

Link Type | Comment |
standard, local DW media links
{{:ns:mediafile|title}} | full qualified links also as relative links, with or without parameters, all detected |
enclosed DW media links
<box params|{{:ns:mediafile|title}}> | all detected |
specials excluded | medialinks within <code>, <file>, <nowiki>, <php>, <html> and %% are ignored
further can be excluded by adding regexpr to plugin conf |
linked external media files
{{http://www.wherever.com/whatsoever.type}} | all detected; if valid, they will be viewed within relative section.
Attention:
mediafile will be displayed as missing in the event a login will be neccesary to open it
(e.g. linked documents from CMS) |
gallery plugin references
{{gallery ... | not recognized, will be displayed as orphan if not otherwise linked |
flashplayer | flashplayer may work for local files (not yet tested sufficiently) |
unc path | not yet tested sufficiently |
windows shares | not yet tested sufficiently |
Each valuable help is welcome. The code is not that complicated, just looping through and
displaying some filename and path info without any effect to your source.

2011-02-28 | Initial release |
The plugin was tested with DW 2010-11-07 “Anteater” and also with related on the Stick version.
This is not the guarantee that it works for all installations due to PHP version dependencies (5.2+).
If you have multiple pictures named e.g. Image006.gif then the tool fails.
Please try to keep good style by authoring and give descriptive names to your media files.
It could happen that not all media files will be detected or some feed links, etc. interpreted as such.
I tried to filter that out but due to that many syntax plugins it cannot catch all issues.
If you have a real problem please tell me the root cause of your problem.
Go to the Configuration Manager and search for OrphanMedia parameters. There is a parameter(”prev_limit”) to restrict the number of pictures to be resized and previewed. Set its value to zero to show pictures just as links.
There is a conflict with the plugin Orphanswanted if you put both into the section of the same page. Please take care to have OrphanMedia syntax on a page without others. That would also speed up your performance.
Thanks to Jürgen for analysing this (see also Issue #92).
Another root cause maybe that your pictures are referenced indirectly by its directory only (e.g. Plugin gallery).
