In Advanced Search, the list of available language is long and will only
get longer. For a library offering books in 2-3 languages, that is
offering too many options to the user (most of the small libraries we
deal with only offer documents in two languages).
Code changes:
Languages.pm: Extract getAllLanguages to make a more customizable
getLanguages (have getAllLanguage call it, so rest of codebase is
oblivious to the change). Build array returned based on system pref if
corresponding argument is set.
search.pl and opac-search.pl: call getLanguages instead of
getAllLanguages.
TESTING
0) All language codes are iso 639-2 (three characters)
1) in OPAC, Advanced search, open Language box, acknowledge 30+ items.
2) in Intranet, go to system preferences AdvancedSearchLanguages,
enter "ita|eng"
3) back in OPAC, refresh screen, acknowledge only Italian and English
are listed.
4) in Intranet, click Search then click "More options" to make the
Language box appear. Acknowledge limited options.
5) Regression Test: Back to the preference, empty the field then save.
Go back to the OPAC and Intranet search, refresh the page, then the
Language drop-box will now contain 30+ items.
