Geeklog Forums

Hi all, I think I've found a bug with GL's multilingual support. Let me explain. At a multilingual-aware site, objects have ids with '_' (underscore) and lnaguage shortcuts at their tail, for example, 'Introduction_en', 'Introduction_de'. In displaying contents, Geeklog uses COM_getLangSQL() and identifies the current langugae a user prefers. This is implemented in COM_getLangSQL() at line 5940, '%' is a wildcard character in SQL, equivalent to '*' in regular expressions. So this code intends "Select ids which ends "_$lang_id". Unfortunately, '_' is a wildcard character in SQL, equivalent to '.' in regular expressions. http://dev.mysql.com/doc/refman/5.0/en/pattern-matching.html Thus, line 5940 picks up any ids which end with any given language shortcuts **WITHOUT** a preceding '_'. This is a bit inconvenient and inconsistent.

This is a better mysql referrence for LIKE: http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html

Nice find, thanks.

It shouldn't be a problem in practice, though. When you're using the multi-language setup, all items with IDs not following the "_lng" pattern wouldn't normally be displayed, so it's unlikely that you will have any items that accidentally match anyway.

Still should be fixed, of course.

Thanks for good info, jmucchiello. so all we have to do is change line 5940 from to Dirk, I'm afraid you have some misunderstanding about '_' character. '_' in SQL matces any one character including '_' itself. Suppose you are going to setup a mutilingual-aware site where visitors can choose between English (shotcut 'en') and German ('de') and you have an article whose id is 'Freunde'. The moment you enable $_CONF['languages'] and $_CONF['language_files'] arrays, all artciles will 'disappear' to all the visitors, but the 'Freunde' artcile will still be displayed to German-speaking people.

No, I understand the problem perfectly (and I tested it with another German word ending in ...de).

What I'm saying is that if you're running a site with multi-language support enabled, you will usually not have any stories (or other items) whose IDs end in anything other then _en, _de, etc. anyway.

bye, Dirk

Ah, I got it. Thanks for the reply, Dirk.

BTW, when I enabled multilingual support on my site, stories without language IDs were displayed in the 'Older Stories' block. When I hit the links, the articles were displayed. I wonder if there is a quick and easy way to fix this.

The contents of the "Older Stories" block are cached. The next time you edit a story or that block, it will be updated.

bye, Dirk

I updated some stories in the 'Older Stories' block and added a new one on my multilingual site. Surely the contents of the 'Older Stories' block were updated, but stories **without** languages IDs are still displayed in the block. I wonder if this is what's supposed to happen.
