Hi Tony, A template variable is any variable that you're using in a tt2 file. The file extension - tt2 - is, as you may already know, the file extension indicating that the file is a Template Toolkit file. So, for example, misc_util.tt2 and summary.tt2 are Template Toolkit files.
To add another MARC field, make the changes in the two files misc_util.tt2 and summary.tt2. (You'll have to name your new variable in misc_util.tt2. MARC 260 c is publication date. The variable has been assigned the name pubdate.) In misc_util.tt2, you're telling the system what the new variable will be. In summary.tt2, you're telling the system to display the data in the search returns. In the examples given in the documentation, where you see "260", you'll substitute whichever other MARC field you want to use. Where you see "@code="c"", you'll be putting the MARC subfield that you want to use.

Perhaps this should have gone to the developers list. If so, I apologize in advance. -------- We're looking to enhance the MARC display in our TPAC (2.3.6) with the addition of some MARC fields. While I did find this, http://docs.evergreen-ils.org/2.3/_designing_your_catalog.html#_configuring_and_customizing_the_public_interface, in the documentation, I'm having some mental issues figuring out what this documentation actually means on a practical basis. For example, the documentations says that if I want to add a MARC 260 field I should do this: ------------------------------------------- "...to map the template variable args.pubdates to the date of publication MARC field 260, subfield c, add these lines to misc_util.tt2:..." args.pubdates = []; FOR sub IN xml.findnodes('//*[@tag="260"]/*[@code="c"]'); args.pubdates.push(sub.textContent); END; args.pubdate = (args.pubdates.size) ? args.pubdates.0 : '' You will then need to edit the /openils/var/templates/opac/parts/record/summary.tt2 file in order to get the template variable for the MARC field to display. For example, to display the date of publication code you created in the misc_util.tt2 file, add these lines: [% IF attrs.pubdate; %] <span itemprop="datePublished">[% attrs.pubdate | html; %]</span> [% END; %] ------------------------------------------- That's understandable to me somewhat, but what if I wanted to add other MARC fields besides the 260? What if I wanted to add a 5XX field or something else? What template variable should I use? What exactly is a template variable? Is there a list of template variables somewhere that I haven't found? Is this a table name somewhere in the DB that I'm overlooking? What position (or where does it go) in this file? I apologize if this is an easy question, but being a regular librarian and not a developer, these terms are still somewhat cryptic to me. If anyone has examples or sites that could demonstrate with a "template variables for dummies" approach, I would be forever in your debt!
