[Koha] Customizing self service to display title

[Krishna K]

Hi,

In the Self Service section of koha the standard procedure is to scan the
barcode of the item in order for the item to be issued. We would like to
customize it such that when the user scans the barcode of the item to be
issued, a popup appears showing the title of the book. We would like to
call the koha perl script within koha like opac-detail.pl to get the tittle
by passing the barcode as an input.

Has anyone done something similar before ? Any help on how to do this will
be most welcome.
