source: branches/1.6/upload.php @ 26010

Last change on this file since 26010 was 1082, checked in by plg, 18 years ago

new: cleaner URL. Instead of category.php?cat=search&search=123&start=42,
you now have category.php?/search/123/start-42. Functions make_index_url and
make_picture_url build these new URLs. Functions duplicate_picture_url and
duplicate_index_url provide shortcuts to URL creation. The current main page
page is still category.php but this can be modified easily in make_index_url
function. In this first version, no backward compatibility. Calendar
definition in URL must be discussed with rvelices.

improvement: picture.php redesigned. First actions like "set as
representative" or "delete a comment" which all lead to a redirection. Then
the page (the big mess) and includes of new sub pages to manage specific
parts of the page (metadata, user comments, rates).

new: with the cleaner URL comes a new terminology. $pagecat doesn't
exist anymore. $pagesection is among 'categories', 'tags' (TODO),
'list', 'most_seen'... And sub parameters are set : $pagecategory if
$pagesection is "categories". See URL analyse in
include/section_init.inc.php for details.
