[Koha-cvs] CVS: koha/opac opac-alert-subscribe.pl,NONE,1.1

[Paul POULAIN]

Update of /cvsroot/koha/koha/opac
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3371/opac

Added Files:
        opac-alert-subscribe.pl 
Log Message:
Letters / alert system, continuing...

* adding a package Letters.pm, that manages Letters & alerts.
* adding feature : it's now possible to define a "letter" for any subscription 
created. If a letter is defined, users in OPAC can put an alert on the 
subscription. When an issue is marked "arrived", all users in the alert will 
recieve a mail (as defined in the "letter"). This last part (= send the mail) 
is not yet developped. (Should be done this week)
* adding feature : it's now possible to "put to an alert" in OPAC, for any 
serial subscription. The alert is stored in a new table, called alert. An alert 
can be put only if the librarian has activated them in subscription (and they 
activate it just by choosing a "letter" to sent to borrowers on new issues)
* adding feature : librarian can see in borrower detail which alerts they have 
put, and a user can see in opac-detail which alert they have put too.

Note that the system should be generic enough to manage any type of alert.
I plan to extend it soon to virtual shelves : a borrower will be able to put an 
alert on a virtual shelf, to be warned when something is changed in the virtual 
shelf (mail being sent once a day by cron, or manually by the shelf owner. 
Anyway, a mail won't be sent on every change, users would be spammed by Koha 
;-) )
