[Koha] editing templates

[William Macfarlane]

For a couple of unimportant reasons I decided that I wanted to edit
the npl opac and intranet search templates to display
items.itemcallnumber as the call number rather than
biblioitems.classification like it does by default.

I don't know anything about html templating, but I imagined that this
would be a pretty simple change to make.  I went into
/usr/local/koha/intranet/htdocs/intranet-tmpl/npl/en/search.marc/result.tmpl
and replaced every instance of "classification" with "itemcallnumber"
.  This results in itemcallnumber displaying in parentheses after the
branch name in the location column (ie "MAIN(530.076)"), but the call
number column, which used to display biblioitems.classification now
displays nothing.

Maybe I'm not understanding how the TMPL_VAR commands work, but it
seems to me that, later in the file, where it is describing the
location column that TMPL_VAR NAME="itemcallnumber" refers to my call
number, but that when I try to use it earlier it is empty, or pointing
to nothing, or something.

On the other hand, replacing "classification" with "itemcallnumber" in
/usr/local/koha/opac/htdocs/opac-tmpl/npl/en/opac-detail.tmpl works
fine, and results in the opac detail page displaying my call numbers
properly.

Both my opac and my intranet are set to display with the NPL
templates, and this works just fine in all other respects.

thanks,
Will
