Find out some details

I have a problem at my wiki, most of the users are school pupils and they often create just empty pages adding just a couple words. Are there any tool that can prevent to create empty pages or pages with just couple of words?

Extension:AbuseFilter

Extension:AbuseFilter will work for this. You can create a rule like this:

 page_id==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 20)

Guys, can you help me please. How to download Extension:AbuseFilter for older version of my wiki. I have 1.29.1

you should use a newer version. Mediawiki 1.29 hasnt been recieving security updates for over a year.

That said, you can get old versions from github https://github.com/wikimedia/mediawiki-extensions-AbuseFilter/archive/REL1_29.zip . I'm not sure if github downloads include vendor dependencies (prob not) so you also have to run composer install --no-dev in the AbuseFilter directory after you have unpacked it

It seems to be that I have successfully installed the extension. So we shall I put this code?:

page_id==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 20)

In localsettings.php file?

Have you tried reading the manual at Extension:AbuseFilter?

Yes, now I try to use it ) Thanks

So, when I try to save the filter in this code:

page_id==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 20)

I have a system mistake, that there is an error in syntax

Syntax seems fine to me, are you sure you tried to add that code exactly?

Here what I have, see the screenshot:

Try

article_articleid==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 20)

instead (older versions of abusefilter might require that instead).

Thanks! Now all seems to be fine, all works!

Can you also help me how to create a filter that will not allow to non-registered users to insert external links in articles?

action == 'edit'
& user_age == 0
& article_namespace == 0
& added_lines rlike 'https?://'

Hi! Can you please help me. I want to make an exception for uploaded files. So it it necessary to provide description and the filter blocks uploading if there isn't such description. So I want users allow to upload files without descriptions

Adding article_namespace !== 6 & or action !== 'upload' & should suffice.

Thanks!

The whole code looks now so:

article_articleid==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 30)
 & action !== 'upload'

Hello! I have updated my wiki to 1.35 and enables VisualEditor. So if I upload the image via VisualEditor, it shows me a message that cannot create empty page. Shall I add to the code exception for uploading a file via VisualEditor

Maybe set exception to "File" namespace.

I can try, can you please let me know how to make such exception to the code I have already

Change action !== 'upload' to article_namespace !== 6

I guess I do something wrong. I have following code:

article_articleid==0
 &!("#redirec" in lcase(added_lines))
 & (new_size < 30)
 & action !== 'upload' to article_namespace !== 6

And I cannot save it as I have message with error

That to isn't valid. You were recommended to replace action !== 'upload' with article_namespace !== 6.

Now all is fine. Thanks

Hi! Could you please help?

i have the code as above and it works fine. But how should I change it if I want allow non-registered users to change the text and link itself on the existing page with such text and link, but at the same time disallow non-registered users to create new pages with links?

Thx! Works perfect!
