From 933a34986dbca248f388e8aa3c3aea4a6d71a94b Mon Sep 17 00:00:00 2001 From: Tim Almdal Date: Thu, 11 Aug 2011 22:04:20 -0700 Subject: Patch for tickets #1428 and #1760 Create the concept of a Photo_Display_Context. If the user is browsing a dynamic album (i.e. tags) and chooses to look at an image in that album. The display of the image happens correctly, but the 'next' and 'previous' buttons are no longer consistent. When one of these is clicked, Gallery will open the adjacent image in the actuall album, not the dynamic album. --- modules/tag/controllers/tag.php | 22 +++++++++++- modules/tag/helpers/tag.php | 19 +++++++++++ modules/tag/libraries/Tag_Display_Context.php | 49 +++++++++++++++++++++++++++ modules/tag/models/tag.php | 38 +++++++++++---------- 4 files changed, 110 insertions(+), 18 deletions(-) create mode 100644 modules/tag/libraries/Tag_Display_Context.php (limited to 'modules/tag') diff --git a/modules/tag/controllers/tag.php b/modules/tag/controllers/tag.php index 7786daa1..06e2b5ed 100644 --- a/modules/tag/controllers/tag.php +++ b/modules/tag/controllers/tag.php @@ -22,7 +22,22 @@ class Tag_Controller extends Controller { $tag_id = $function; $tag = ORM::factory("tag")->where("id", "=", $tag_id)->find(); $page_size = module::get_var("gallery", "page_size", 9); - $page = (int) Input::instance()->get("page", "1"); + + $input = Input::instance(); + $show = $input->get("show"); + + if ($show) { + $child = ORM::factory("item", $show); + $index = tag::get_position($tag, $child); + if ($index) { + $page = ceil($index / $page_size); + $uri = "tag/$tag_id/" . urlencode($tag->name); + url::redirect($uri .
