Hey,
On my local wiki I have a page with the name "File:Blue marker.png". The
following code returns false:
$title = Title::makeTitle( NS_FILE, $file );
$title->exists();
That used to return true in the past. Not sure what is broken - my wiki or
MediaWiki itself.
You're sure about that? I think you're just mixing up $title->exists()
and $title->isKnown().
$title = Title::makeTitle( NS_FILE, $filename );
$file = wfLocalFile( $title );
$file->getUrl();
That's generally right, but depending on the exact context, the
following might be more appropriate:
$title = Title::makeTitle( NS_FILE, $filename );
$file = wfFindFile( $title );
$file->getFullUrl(); // or $file->getCanonicalUrl(); if you need the protocol.
wfLocalFile will always return a file object even if there is no file
by that name (And it will take its best guess at the url even for
non-existent files). If the name given would normally be a foreign
file, wfLocalFile( 'Foo.jpg' )->getUrl() would return what the url
would be if there was a local file of that name. On the other hand,
wfFindFile will return the appropriate (possibly foreign) file for
that name or false if none exists.
In almost all cases you would probably want the wfFindFile behavior
and not wfLocalFile().
