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.
my $string = DisplayISBN( $isbn );
$itemtypename = &GetSupportName($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).
build a HTML select with the following code :
my $itemtypes = GetSupportList();
$template->param(itemtypeloop => $itemtypes);
<form action='<!-- TMPL_VAR name="script_name" -->' method=post>
<select name="itemtype">
<option value="">Default</option>
<!-- TMPL_LOOP name="itemtypeloop" -->
<option value="<!-- TMPL_VAR name="itemtype" -->" <!-- TMPL_IF name="selected" -->selected<!-- /TMPL_IF -->> <!--TMPL_IF Name="imageurl"--><img alt="<!-- TMPL_VAR name="description" -->" src="<!--TMPL_VAR Name="imageurl"-->><!--TMPL_ELSE-->"<!-- TMPL_VAR name="description" --><!--/TMPL_IF--></option>

<input type=text name=searchfield value="<!-- TMPL_VAR name="searchfield" -->">
<input type="submit" value="OK" class="button">
</form>
$itemtypes = &GetItemTypes();
Returns information about existing itemtypes.
build a HTML select with the following code :

foreach my $thisitemtype (sort keys %$itemtypes) {
my $selected = 1 if $thisitemtype eq $itemtype;
my %row =(value => $thisitemtype,
selected => $selected,
description => $itemtypes->{$thisitemtype}->{'description'},
);
push @itemtypesloop, \%row;

$frameworks = &getframework();

build a HTML select with the following code :
my $frameworks = frameworks(); my @frameworkloop; foreach my $thisframework (keys %$frameworks) { my $selected = 1 if $thisframework eq $frameworkcode; my %row =(value => $thisframework, selected => $selected, description => $frameworks->{$thisframework}->{'frameworktext'}, ); push @frameworksloop, \%row; } $template->param(frameworkloop => \@frameworksloop);

$frameworkinfo = &getframeworkinfo($frameworkcode);
Returns information about an frameworkcode.
$itemtype = &getitemtype($itemtype);
Returns information about an itemtype.
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' => 'MARC-8'
'icon' => undef,
'id' => 'LIBRARY OF CONGRESS',
'label' => '',
'name' => 'server',
'opensearch' => '',
'value' => 'z3950.loc.gov:7090/',
'zed' => 1,
},
$authvalcode = GetAuthValCode($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.
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
# field is a MARC::Field object my $display_form = C4::Koha::display_marc_indicators($field);
Generate a display form of the indicators of a variable MARC field, replacing any blanks with '#'.
