From 6ba98e8cf282885c7d515865d93ed1fa5238e703 Mon Sep 17 00:00:00 2001 From: Colin Campbell Date: Wed, 6 Apr 2011 15:34:13 +0100 Subject: [PATCH] Bug 5529 Absence or Presence of lists not being reliably returned Content-Type: text/plain; charset="utf-8" C4::VirtualShelves::GetRecentShelves contained some rather confused code The contents of the requested list are returned in an arrayref which was in its turn being wrapped needlessly in an array As a result the returned array always consisted of a single element irrespective of the number of lists. Made the routine return the arrayref, which can now be tested directly Unfortunately rather than fixing this we had previously coded around it assuming it to be a "design" decision. Have amended other calls of the subroutine resulting in some hopefully less obscure code Fixed logic error in the results template which displayed new list within a test for the presence of lists Removed the offset parameter from the sql in the routine as it was hardcoded to 0 i.e. the default value --- C4/Auth.pm | 44 ++++++++++---------- C4/VirtualShelves.pm | 44 +++++++++++-------- C4/VirtualShelves/Page.pm | 12 +++--- catalogue/search.pl | 15 +++---- .../prog/en/modules/catalogue/results.tmpl | 2 +- virtualshelves/addbybiblionumber.pl | 4 +- 6 files changed, 62 insertions(+), 59 deletions(-) diff --git a/C4/Auth.pm b/C4/Auth.pm index 35c0838..7a0c13e 100644 --- a/C4/Auth.pm +++ b/C4/Auth.pm @@ -164,19 +164,19 @@ sub get_template_and_user { $template->param( loggedinusername => $user ); $template->param( sessionID => $sessionID ); - my ($total, $pubshelves, $barshelves) = C4::Context->get_shelves_userenv(); - if (defined($pubshelves)) { - $template->param( pubshelves => scalar (@$pubshelves), - pubshelvesloop => $pubshelves, - ); - $template->param( pubtotal => $total->{'pubtotal'}, ) if ($total->{'pubtotal'} > scalar (@$pubshelves)); - } - if (defined($barshelves)) { - $template->param( barshelves => scalar (@$barshelves), - barshelvesloop => $barshelves, - ); - $template->param( bartotal => $total->{'bartotal'}, ) if ($total->{'bartotal'} > scalar (@$barshelves)); - } + my ($total, $pubshelves, $barshelves) = C4::Context->get_shelves_userenv(); + if (defined($pubshelves)) { + $template->param( pubshelves => scalar @{$pubshelves}, + pubshelvesloop => $pubshelves, + ); + $template->param( pubtotal => $total->{'pubtotal'}, ) if ($total->{'pubtotal'} > scalar @{$pubshelves}); + } + if (defined($barshelves)) { + $template->param( barshelves => scalar @{$barshelves}, + barshelvesloop => $barshelves, + ); + $template->param( bartotal => $total->{'bartotal'}, ) if ($total->{'bartotal'} > scalar @{$barshelves}); + } $borrowernumber = getborrowernumber($user) if defined($user); @@ -297,11 +297,11 @@ sub get_template_and_user { $template->param( sessionID => $sessionID ); my ($total, $pubshelves) = C4::Context->get_shelves_userenv(); # an anonymous user has no 'barshelves'... - if (defined(($pubshelves))) { - $template->param( pubshelves => scalar (@$pubshelves), + if (defined $pubshelves) { + $template->param( pubshelves => scalar @{$pubshelves}, pubshelvesloop => $pubshelves, ); - $template->param( pubtotal => $total->{'pubtotal'}, ) if ($total->{'pubtotal'} > scalar (@$pubshelves)); + $template->param( pubtotal => $total->{'pubtotal'}, ) if ($total->{'pubtotal'} > scalar @{$pubshelves}); } } @@ -852,12 +852,12 @@ sub checkauth { $total->{'bartotal'} = $totshelves; ($pubshelves, $totshelves) = C4::VirtualShelves::GetRecentShelves(2, $row_count, undef); $total->{'pubtotal'} = $totshelves; - $session->param('barshelves', $barshelves->[0]); - $session->param('pubshelves', $pubshelves->[0]); + $session->param('barshelves', $barshelves); + $session->param('pubshelves', $pubshelves); $session->param('totshelves', $total); - C4::Context::set_shelves_userenv('bar',$barshelves->[0]); - C4::Context::set_shelves_userenv('pub',$pubshelves->[0]); + C4::Context::set_shelves_userenv('bar',$barshelves); + C4::Context::set_shelves_userenv('pub',$pubshelves); C4::Context::set_shelves_userenv('tot',$total); } else { @@ -877,9 +877,9 @@ sub checkauth { my ($total, $totshelves, $pubshelves); ($pubshelves, $totshelves) = C4::VirtualShelves::GetRecentShelves(2, $row_count, undef); $total->{'pubtotal'} = $totshelves; - $session->param('pubshelves', $pubshelves->[0]); + $session->param('pubshelves', $pubshelves); $session->param('totshelves', $total); - C4::Context::set_shelves_userenv('pub',$pubshelves->[0]); + C4::Context::set_shelves_userenv('pub',$pubshelves); C4::Context::set_shelves_userenv('tot',$total); # setting a couple of other session vars... diff --git a/C4/VirtualShelves.pm b/C4/VirtualShelves.pm index 7257149..5bddadb 100644 --- a/C4/VirtualShelves.pm +++ b/C4/VirtualShelves.pm @@ -186,9 +186,9 @@ sub GetShelvesSummary ($$$$) { =head2 GetRecentShelves - ($shelflist) = GetRecentShelves(1, $limit, $owner) + ($shelflist, $total) = GetRecentShelves(1, $limit, $owner) -This function returns a references to an array of hashrefs containing specified shelves sorted +This function returns a reference to an array of hashrefs containing specified shelves sorted by the date the shelf was last modified in descending order limited to the number of records specified by C<$row_count>.
