Blosxom

I'm using the moreentries plugin to have links to "Next 10 stories" and
"Previous 10 stories" at the bottom of my page at http://www.modspil.dk.

This used to work with categories, so that if you went into a category
(say http://www.modspil.dk/billeder/) and clicked "Næste 10" in the
bottom, you'd go the the next ten for the CATEGORY, i.e. 

http://www.modspil.dk/billeder/?_start=11

However, the link is now NOT to the category, but to the main page:

http://www.modspil.dk/?_start=11

Why is that? It might be due to a conflict with another plugin, but I
have no IDEA when this broke. All I know is it used to work.

Any ideas, including ideas how to fix it?

Thank you very much in advance for any suggestions.

The work for figuring out the base URL is done by CGI::self_url(): #setup prevlink, nextlink my $url = blosxom::self_url(); $url =~ s/[&\?;]_start=\d+//g; $url =~ s/[&?;]-\w+=\d+//g; $url =~ s/\?\s*$//; So unless your categories are being stripped by those regexps, which seems unlikely, that is pretty much all there is to it. You might try logging $url at various places to stderr and seeing what is changing it. Best Regards, Steve Blog: http://agilitynerd.com/ Dog Agility Search: http://googility.com/

Do you know where this is configured and what could affect it?

This page has more info on self_url() and url(): http://cpansearch.perl.org/src/LDS/CGI.pm-3.49/cgi_docs.html You might grep all your plugins for self_url and see if one of them is overwriting blosxom::self_url (a long shot) You could also explicitly invoice CGI::self_url() instead of blosxom::self_url() and see what happens.

In other words, something seems to be wrong with this function? Should I check the version of my ISPs installation of the CGI library? Any clues - I confess I'm a novice to Perl?

My ISP is running Perl 5.8.9 with CGI version 3.42. This actually works on my own test server, where I'm running Perl 5.10 with CGI version 3.29. Maybe some defaults for self_url changed from 3.29 to 3.42.? Well, for now I've got so far as to write my ISP about it, nut since self_url() according to CPAN is supposed to return the URL of the script itself, it may be the plugin and not my ISPs version that has the bug (http://search.cpan.org/~lds/CGI.pm-3.49/lib/CGI.pm). But I think I won't decide either way until my ISP answers something abt what might go wrong.

But as I wrote earlier, self_url is not a documented way of getting the current URL, but of getting the URL of the CGI script. When running through Apache's rewrite engine, I suppose the result of such a function is undefined, and I don't think the "new" beaviour, which breaks the moreentries plugin, is necessarily any worse than the "old" one which didn't. I think this is a more correct way of getting the current URL: > my $url = "$blosxom::url/$blosxom::path_info"; > This actually solves the problem. Now, the next question is: Can anyone think of a reason not to do it that way, and if not, how do I propose it for a patch to the plugin? br Carsten

I have a version of moreentries, based on your good work with a couple of minor fixes for special characters in the URL (I have a category called "People+Places" which has caused various plugins some trouble). I've just tested and it doesn't have the problem the OP reported. My version v0.4 of moreentries is available from http://www.leverton.org/blosxom/Software/Projects/Blosxom/ Nick

It will have this problem, though, if run with the same version of the CGI library as my ISP. To fix it, you should replace the line my $url = blosxom::self_url(); with my $url = "$blosxom::url/$blosxom::path_info"; which I thinks is more correct, as "self URL" refers the the script's URL and this might not include categories. br Carsten
