C4::VirtualShelves - Functions for manipulating Koha virtual virtualshelves
use C4::VirtualShelves;
This module provides functions for manipulating virtual virtualshelves, including creating and deleting virtualshelves, and adding and removing bibs to and from virtualshelves.
($shelflist, $totshelves) = &GetShelves($mincategory, $row_count, $offset, $owner);
($shelfnumber, $shelfhash) = each %{$shelflist};
Returns the number of shelves specified by $row_count and $offset as well as the total number of shelves that meet the $owner and $mincategory criteria. $mincategory, $row_count, and $offset are required. $owner must be supplied when $mincategory == 1. When $mincategory is 2 or 3, supply undef as argument for $owner. $shelflistis a reference-to-hash. The keys are the virtualshelves numbers ($shelfnumber, above), and the values ($shelfhash, above) are themselves references-to-hash, with the following keys:
$shelfhash->{shelfname}A string. The name of the shelf.
$shelfhash->{count}The number of virtuals on that virtualshelves.
($shelves, $total) = GetShelvesSummary($mincategory, $row_count, $offset, $owner)
Returns the number of shelves specified by $row_count and $offset as well as the total number of shelves that meet the $owner and/or $mincategory criteria. $mincategory, $row_count, and $offset are required. $owner must be supplied when $mincategory == 1. When $mincategory is 2 or 3, supply undef as argument for $owner.
($shelflist) = GetRecentShelves(1, $limit, $owner)
This function returns a references 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 $row_count. If calling with $mincategory other than 1, use undef as $owner.
This function is intended to return a dataset reflecting the most recently active shelves for the submitted parameters.
(shelfnumber,shelfname,owner,category,sortfield) = &GetShelf($shelfnumber);
Looks up information about the contents of virtual virtualshelves number $shelfnumber
Returns the database's information on 'virtualshelves' table.
$biblist = &GetShelfContents($shelfnumber);
Looks up information about the contents of virtual virtualshelves number $shelfnumber. Sorted by a field in the biblio table. copyrightdate gives a desc sort.
Returns a reference-to-array, whose elements are references-to-hash, as returned by C4::Biblio::GetBiblioFromItemNumber.
Note: the notforloan status comes from the itemtype, and where it equals 0 it does not ensure that related items.notforloan status is likewise 0. The caller has to check any items on their own, possibly with CanBookBeIssued from C4::Circulation.
$shelfnumber = &AddShelf( $shelfname, $owner, $category);
Creates a new virtual virtualshelves with name $shelfname, owner $owner and category $category.
Returns a code to know what's happen. * -1 : if this virtualshelves already exist. * $shelfnumber : if success.
&AddToShelf($biblionumber, $shelfnumber);
Adds bib number $biblionumber to virtual virtualshelves number $shelfnumber, unless that bib is already on that shelf.
ModShelf($shelfnumber, $hashref)
Where $hashref->{column} = param
Modify the value into virtualshelves table with values given from hashref, which each key of the hashref should be the name of a column of virtualshelves.
ShelfPossibleAction($loggedinuser, $shelfnumber, $action);
$loggedinuser,$shelfnumber,$action
$action can be "view" or "manage".
Returns 1 if the user can do the $action in the $shelfnumber shelf. Returns 0 otherwise.
&DelFromShelf( $biblionumber, $shelfnumber);
Removes bib number $biblionumber from virtual virtualshelves number $shelfnumber. If the bib wasn't on that virtualshelves to begin with, nothing happens.
($status, $msg) = &DelShelf($shelfnumber);
Deletes virtual virtualshelves number $shelfnumber. The virtualshelves must be empty.
Returns a two-element array, where $status is 0 if the operation was successful, or non-zero otherwise. $msg is "Done" in case of success, or an error message giving the reason for failure.
$Number = DelShelf($shelfnumber);
This function deletes the shelf number, and all of it's content.
This finds all the public lists that this bib record is in.
($total, $pubshelves, $barshelves) = RefreshShelvesSummary($sessionID, $loggedinuser, $row_count);
Updates the current session and userenv with the most recent shelves
Returns the total number of shelves stored in the session/userenv along with two references each to an array of hashes, one containing the $loggedinuser's private shelves and one containing all public/open shelves.
This function is used in conjunction with the 'Lists' button in masthead.inc.
