C4::Letters - Give functions for Letters management
use C4::Letters;
"Letters" is the tool used in Koha to manage informations sent to the patrons and/or the library. This include some cron jobs like late issues, as well as other tasks like sending a mail to users that have subscribed to a "serial issue alert" (= being warned every time a new issue has arrived at the library) Letters are managed through "alerts" sent by Koha on some events. All "alert" related functions are in this module too.
$letters = &GetLetters($module); returns informations about letters. if needed, $module filters for letters given module
my $letter_templates = GetLetterTemplates(
{
module => 'circulation',
code => 'my code',
branchcode => 'CPL', # '' for default,
}
);
Return a hashref of letter templates.
The key will be the message transport type.
my $letters = GetLettersAvailableForALibrary(
{
branchcode => 'CPL', # '' for default
module => 'circulation',
}
);
Return an arrayref of letters, sorted by name.
If a specific letter exist for the given branchcode, it will be retrieve.
Otherwise the default letter will be.
DelLetter(
{
branchcode => 'CPL',
module => 'circulation',
code => 'my code',
[ mtt => 'email', ]
}
);
Delete the letter. The mtt parameter is facultative.
If not given, all templates mathing the other parameters will be removed.
parameters :
- $borrowernumber : the number of the borrower subscribing to the alert
- $type : the type of alert.
- $externalid : the primary key of the object to put alert on. For issues, the alert is made on subscriptionid.
create an alert and return the alertid (primary key)
parameters :
- alertid : the alert id
deletes the alert
parameters :
- $borrowernumber : the number of the borrower subscribing to the alert
- $type : the type of alert.
- $externalid : the primary key of the object to put alert on. For issues, the alert is made on subscriptionid.
all parameters NON mandatory. If a parameter is omitted, the query is done without the corresponding parameter. For example, without $externalid, returns all alerts for a borrower on a topic.
parameters :
- $type : the type of alert
- $externalid : the id of the "object" to query
In the table alert, a "id" is stored in the externalid field. This "id" is related to another table, depending on the type of the alert.
When type=issue, the id is related to a subscriptionid and this sub returns the name of the biblio.
parameters :
- $type : the type of alert
- $externalid : the id of the "object" to query
- $letter_code : the letter to send.
send an alert to all borrowers having put an alert on a given subject.
Returns undef or { error => 'message } on failure.
Returns true on success.
%params hash:
module => letter module, mandatory
letter_code => letter code, mandatory
branchcode => for letter selection, if missing default system letter taken
tables => a hashref with table names as keys. Values are either:
- a scalar - primary key value
- an arrayref - primary key values
- a hashref - full record
substitute => custom substitution key/value pairs
repeat => records to be substituted on consecutive lines:
- an arrayref - tries to guess what needs substituting by
taking remaining << >> tokensr; not recommended
- a hashref token => @tables - replaces <token> << >> << >> </token>
subtemplate for each @tables row; table is a hashref as above
want_librarian => boolean, if set to true triggers librarian details
substitution from the userenv
Return value:
letter fields hashref (title & content useful)
parameters :
- $letter : a hash to letter fields (title & content useful)
- $table : the Koha table to parse.
- $values_in : table record hashref
parse all fields from a table, and replace values in title & content with the appropriate value
(not exported sub, used only internally)
my $success = EnqueueLetter( { letter => $letter,
borrowernumber => '12', message_transport_type => 'email' } )
places a letter in the message_queue database table, which will eventually get processed (sent) by the process_message_queue.pl cronjob when it calls SendQueuedMessages.
return message_id on success
my $sent = SendQueuedMessages( { verbose => 1 } );
sends all of the 'pending' items in the message queue.
returns number of messages sent.
my $message_list = GetRSSMessages( { limit => 10, borrowernumber => '14' } )
returns a listref of all queued RSS messages for a particular person.
my $message_list = GetPrintMessages( { borrowernumber => $borrowernumber } )
Returns a arrayref of all queued print messages (optionally, for a particular person).
my $messages = GetQueuedMessage( { borrowernumber => '123', limit => 20 } );
fetches messages out of the message queue.
returns: list of hashes, each has represents a message in the message queue.
my @mtt = GetMessageTransportTypes(); returns an arrayref of transport types
named parameters: letter - the standard letter hashref attachments - listref of attachments. each attachment is a hashref of: type - the mime type, like 'text/plain' content - the actual attachment filename - the name of the attachment. message - a MIME::Lite object to attach these to.
returns your letter object, with the content updated.
