Topic on Project:Support desk

I want non-existent pages in certain namespace to show a hyperlink to an external site. I guess this can be done with templates.

But is it possible for all non-existent pages in a namespace to display a template? After all the page is non-existent, can it display anything?

I need this feature for default placeholders of yet empty namespace, which is to have too many entries (around 10000) to add a template to every entry manually.

I suspect MediaWiki does not support this. I know PHP, what can be done to implement this?

Simply add the template to MediaWiki:Noarticletext.

{{#ifeq: {{NAMESPACE}} | Project | {{A template}} }}

But can I also make this to appear in the textarea by default when somebody clicks "Create" button for the page in question?

I do not want this template to disappear when somebody edits the page.

That is possible with a hook. You would have to check, which one, though.

For this there is Extension:PreloadManager extension, but it is unmaintained.

I consider to become its maintainer.

I think the following extensions might work:

• Extension:NewArticleTemplate

• Extension:BoilerRoom

Haven't used them but Extension:NewArticleTemplate appears to more versatile.

Another Extension:MultiBoilerplate, "allows a boilerplate [template] to be selected from a drop down box located above the edit form when editing [new] pages"
