Bug 8995: Show OpenURL links in OPAC search results

This patch use GetCOinS sub to provide an OpenURL link in OPAC search results. It uses 4 new system preferences: - OpenURLinOPACResults: enable or disable this feature - OpenURLResolverURL: url of the openURL resolver - OpenURLText: text of the link - OpenURLImageLocation: image of the link Link is displayed as an image if OpenURLImageLocation is defined, and as text otherwise. It works both with and without XSLT enabled. Changes made to GetCOinSBiblio: For 'journal': - Title should be in rft.jtitle instead of rft.title - rft.date, rft.aulast, rft.aufirst, rft.au, rft.pub and rft.pages have no meaning for a subscription, so they are simply removed from URL This patch refactors GetCOinSBiblio, so the construction of URL is done only at the end. This way we do not have ugly $var .= "&$value" in the function body. Also use URI::Escape instead of custom regexps. This development consider the value of syspref OPACURLOpenInNewWindow when building the link. Test plan: 1/ Enable syspref OPACShowOpenURL and put your OpenURL resolver URL in OpenURLResolverURL syspref (if you don't have one, just fill it with some fake URL, you'll have to check if OpenURL links are correct) 2/ If you want, set the other sysprefs OpenURLImageLocation and OpenURLText 3/ Fill syspref OPACOpenURLItemTypes with some (not all) of your item types. 4/ Empty sysprefs OPACXSLTDetailsDisplay and OPACXSLTResultsDisplay 5/ Go to OPAC and launch a search. 6/ Check you have in the results (near the title) the OpenURL link (only for itemtypes that are in OPACOpenURLItemTypes). Toggle OPACURLOpenInNewWindow syspref and check that the behaviour of the link is correct. 7/ Go to the detail page of one of those and check you have the OpenURL link too. (Above tags) Toggle OPACURLOpenInNewWindow syspref and check that the behaviour of the link is correct. 8/ Set sysprefs OPACXSLTDetailsDisplay and OPACXSLTResultsDisplay to "default" and repeat steps 5 to 7 Signed-off-by: Paola Rossi <paola.rossi@cineca.it> Signed-off-by: Magnus Enger <magnus@libriotech.no> Signed-off-by: Martin Renvoize <martin.renvoize@ptfs-europe.com> Signed-off-by: Nick Clemens <nick@bywatersolutions.com>
