Let’s assume you have a default installation of b2evolution:
- Blog All can be accessed through
- Blog A can be accessed through
- Blog B can be accessed through
- The Linkblog can be accessed through
Let’s start with Blog A
Let’s start with blog A, because it is the easiest. b2evolution ships with an alternative file to call blog A! In your URL, try replacing the end
a_stub.php. You should access the exact same page. That’s because b2evolution ships with the file
a_stub.php which is preconfigured for acting as if
index.php was called with parameter
However, if you now click on an internal link on this page, say "Last comments", you will notice that b2evo throws you back to
That’s because b2evo doesn’t know (yet) that you want to use
a_stub.php instead of
index.php?blog=2. You must set this up in the admin, under blogs then Blog A. Under "Preferred access type:", you must select "Explicit reference to stub file (Advanced)" and then name the stub file name in "Stub name:"; here you should enter
a_stub.php. Validate your changes.
Now, you can refresh the blog page and click on some links. You will notice that you now stay on
a_stub.php and no longer get redirected to
Now with Blog B
Try the same operations as above on blog B (blog number 3) and try to associate it with a stub file named
b_stub.php. You will notice that you get a "404 Page not found" error from your webserver!
That is because b2evolution does not ship with a file named
Now try to duplicate the file
b_stub.php on your webserver.
What happens if you acces this page? You will notice that you no longer get an error, but
b_stub.php displays Blog A just as
a_stub.php did! This is not what you wanted!
This happens because
b_stub.php contains preset parameters so that you don’t have to pass these on the URL. In this case, it contains a hardcoding for
blog=2 and blog #2 is blog A, not blog B. (You can see the blog numbers in the admin, under Blogs).
To correct that, you must open the file
b_stub.php with a text editor and find the following line:
$blog = 2; // 2 is for "demo blog A" or your upgraded blog (depends on your install)
Replace this line with:
$blog = 3;
Take special care not to forget the $ sign in front of $blog, as well as the semi column ( ; ) at the end of the line. The white space and the comment after // can be omitted.
Save the file (and upload it to your webserver if necessary).
b_stub.php should now work as expected. :)
b_stub.php is what we call a Stub File. You may have noticed that it also lets you set other parameters than just the blog number. For more information on this, see StubFiles.
In short, this is how a stub-file looks like
