Description: | Return unused files |
Extension / Version: | DPL / ? |
Type / Status: | Change Request / open |
Problem
Is there a way to select images that are used (il_to NOT NULL, linked to by any other page)) or unsed?
I want to return a simple list of unused images, but also in combination, e.g. unused files, uploaded by a specifed user.
This should actually return a simple list of 5 unused files (if I understand the parameter correctly), but it doesn't.
{{#dpl: |debug=3 |namespace=Image |notlinksfrom=% |count=5 }}

The problem is that notlinksfrom expects an exact article name; it does not understand 'LIKE %'.
Work around
You can nest two queries; the first one produces a list of all images and calls another template for each ofg the images. The second query produces output only if the imageused clause is false.
---------------------------------------- Code in a page named 'check list for unused images' (e.g.) ===Unused Images=== {{#dpl: |namespace=Image |format=,²{Unused Image¦%PAGE%}², |count=100 }} ---------------------------------------- Code in page 'Template:Unused Image' {{#replace: {{#dpl: |imageused={{{1}}} |resultsheader=OOKK |noresultsheader=\n* [[{{{1}}}]] }}|/.*OOKK.*/| }} ---------------------------------------- end
The code in the second template generates the lsit of articles which use an image; the #replace throws the whole list away if there was at least one match; otherwise it outputs the name of the image under question.

- Oh thanks for the code. It returns the pages it checked as well. But those links which are images are really unused. Link (will remove my link after next reply).

{{dpl: |namespace=File |format=,%UNLINKED% }}
- Result: All unused image pages. --Subfader 21:44, 1 May 2009 (UTC)
