C4::Koha - Perl Module containing convenience functions for Koha scripts
use C4::Koha;
Koha.pm provides many functions for Koha scripts.
$slash_date = &slashifyDate($dash_date);
Takes a string of the form "DD-MM-YYYY" (or anything separated by dashes), converts it to the form "YYYY/MM/DD", and returns the result.
$itemtypename = &GetSupportName($codestring);
Returns a string with the name of the itemtype.
$itemtypes = &GetSupportList();
Returns an array ref containing informations about Support (since itemtype is rather a circulation code when item-level-itypes is used).

$frameworkinfo = &getframeworkinfo($frameworkcode);
Returns information about an frameworkcode.
$itemtype = &getitemtypeinfo($itemtype, [$interface]);
Returns information about an itemtype. The optional $interface argument sets which interface ('opac' or 'intranet') to return the imageurl for. Defaults to intranet.
my $directory = getitemtypeimagedir( 'opac' );
pass in 'opac' or 'intranet'. Defaults to 'opac'.
returns the full path to the appropriate directory containing images.
Find all of the image files in a directory in the filesystem
parameters: a directory name
returns: a list of images in that directory.
Notes: this does not traverse into subdirectories. See _getSubdirectoryNames for help with that. Images are assumed to be files with .gif or .png file extensions. The image names returned do not have the directory name on them.
Find all of the directories in a directory in the filesystem
parameters: a directory name
returns: a list of subdirectories in that directory.
Notes: this does not traverse into subdirectories. Only the first level of subdirectories are returned. The directory names returned don't have the parent directory name on them.
returns: a listref of hashrefs. Each hash represents another collection of images.
{ imagesetname => 'npl', # the name of the image set (npl is the original one)
images => listref of image hashrefs
}
each image is represented by a hashref like this:
{ KohaImage => 'npl/image.gif',
StaffImageUrl => '/intranet-tmpl/prog/img/itemtypeimg/npl/image.gif',
OpacImageURL => '/opac-tmpl/prog/itemtypeimg/npl/image.gif'
checked => 0 or 1: was this the image passed to this method?
Note: I'd like to remove this somehow.
}
$printers = &GetPrinters(); @queues = keys %$printers;
Returns information about existing printer queues.
$printers is a reference-to-hash whose keys are the print queues defined in the printers table of the Koha database. The values are references-to-hash, whose keys are the fields in the printers table.
$printer = GetPrinter( $query, $printers );
Returns the number of pages to display in a pagination bar, given the number of items and the number of items per page.
(@themes) = &getallthemes('opac');
(@themes) = &getallthemes('intranet');
Returns an array of all available themes.
Return a href where a key is associated to a href. You give a query, the name of the key among the fields returned by the query. If you also give as third argument the name of the value, the function returns a href of scalar. The optional 4th argument is an arrayref of items passed to the execute() call. It is designed to bind parameters to any placeholders in your SQL.
my $query = '
SELECT itemnumber,
notforloan,
barcode
FROM items
';
# generic href of any information on the item, href of href.
my $iteminfos_of = get_infos_of($query, 'itemnumber');
print $iteminfos_of->{$itemnumber}{barcode};
# specific information, href of scalar
my $barcode_of_item = get_infos_of($query, 'itemnumber', 'barcode');
print $barcode_of_item->{$itemnumber};
my $notforloan_label_of = get_notforloan_label_of();
Each authorised value of notforloan (information available in items and itemtypes) is link to a single label.
Returns a href where keys are authorised values and values are corresponding labels.
foreach my $authorised_value (keys %{$notforloan_label_of}) {
printf(
"authorised_value: %s => %s\n",
$authorised_value,
$notforloan_label_of->{$authorised_value}
);
}
my $servers = displayServers(); my $servers = displayServers( $position ); my $servers = displayServers( $position, $type );
displayServers returns a listref of hashrefs, each containing information about available z3950 servers. Each hashref has a format like:
{
'checked' => 'checked',
'encoding' => 'utf8',
'icon' => undef,
'id' => 'LIBRARY OF CONGRESS',
'label' => '',
'name' => 'server',
'opensearch' => '',
'value' => 'lx2.loc.gov:210/',
'zed' => 1,
},
$authhorised_value = GetKohaImageurlFromAuthorisedValues( $category, $authvalcode );
Return the first url of the authorised value image represented by $lib.
$authvalcode = GetAuthValCode($kohafield,$frameworkcode);
$authvalcode = GetAuthValCodeFromField($field,$subfield,$frameworkcode);
$subfield can be undefined
$authvalues = GetAuthorisedValues([$category], [$selected]);
This function returns all authorised values from the'authorised_value' table in a reference to array of hashrefs.
$category returns authorised values for just one category (optional).
$opac If set to a true value, displays OPAC descriptions rather than normal ones when they exist.
$auth_categories = GetAuthorisedValueCategories();
Return an arrayref of all of the available authorised value categories.
$is_auth_val_category = IsAuthorisedValueCategory($category);
Returns whether a given category name is a valid one
$authhorised_value = GetAuthorisedValueByCode( $category, $authvalcode );
Return the lib attribute from authorised_values from the row identified by the passed category and code
Takes $kohafield, $fwcode as parameters.
If $opac parameter is set to a true value, displays OPAC descriptions rather than normal ones when they exist.
Returns hashref of Code => description
Returns undef if no authorised value category is defined for the kohafield.
Takes $field, $subfield, $fwcode as parameters.
If $opac parameter is set to a true value, displays OPAC descriptions rather than normal ones when they exist. $subfield can be undefined
Returns hashref of Code => description
Returns undef if no authorised value category is defined for the given field and subfield
my $escaped_string = C4::Koha::xml_escape($string);
Convert &, <, >, ', and " in a string to XML entities
Takes $category, $authorised_value as parameters.
If $opac parameter is set to a true value, displays OPAC descriptions rather than normal ones when they exist.
Returns authorised value description
AddAuthorisedValue($category, $authorised_value, $lib, $lib_opac, $imageurl);
Create a new authorised value.
my $display_form = C4::Koha::display_marc_indicators($field);
$field is a MARC::Field object
Generate a display form of the indicators of a variable MARC field, replacing any blanks with '#'.
Takes a hashref of options
Currently supported options are:
'id' An exact quote id 'random' Select a random quote noop When no option is passed in, this sub will return the quote timestamped for the current day
The function returns an anonymous hash following this format:
{
'source' => 'source-of-quote',
'timestamp' => 'timestamp-value',
'text' => 'text-of-quote',
'id' => 'quote-id'
};
