It might be possible to hide the link by using CSS. It may depend on the
method your patrons use to authenticate. We use Shibboleth. When a
patron is not logged in, the CSS class for <BODY> is "branch-default".
When the patron is logged in, the class is "branch-LUP". We only have
one branch, but presumably that would change depending on the branch the
patron is logged in to.
You could probably use some CSS like
.branch-default .online_resources {
display: none;
}
This might depend upon which XSLT you're using for the display.

Could you send a link to an example record? It's possible your URL is in an
unexpected format. I assumed that the text ".pdf" would appear somewhere in
the URL but if it does not, then the code will not work.

Dear Eric,
Thank you for your explanation. Hope it could be possible in the future.
I tried to copy your script (hide-pdf-urls.js) in OPACUserJS, and searched
collection with PDF file in 856$u. But it doesn't change the link of
"Online access: Click here to access online" both in the search result and
detail.pl page (the link still goes to my PDF file). Do I miss something
in the setting?
Regards,
Ketut Gunawan

Hi Ketut,
I'm sure someone will correct me if I'm wrong, but I don't think it's
possible to modify the display of records based on whether or not someone
is signed in. You can modify their display by editing Koha's XSLT
templates. See Koha > koha-tmpl > opac-tmpl > bootstrap > en > xslt, here's
an example one. But there is no way to change these conditionally based on
whether a user is authenticated or not.
You could simulate this with some jQuery:
https://gist.github.com/phette23/f4595ae6b8bddcf8d55cd12cc378253a
You would add this to your OPACUserJS setting. But it's not truly safe;
users could disable JavaScript and they would see the PDF URLs, or they
could view or export the underlying bibliographic record to find the URL.
The only truly safe way to do this is to put the PDFs behind authentication
somewhere e.g. in an institutional repository.

Dear all,
I am new to Koha so I need helps. I have a subfield 856$u containing PDF
files in hundred of records. I want to hide it in OPAC so that public
visitors cannot see "Online resources: Click here to access online", but
for those who log in (students) can see and click such a link.
I have tried to read the manual and search the forum, but I can find it.
Any help would be much appreciated.
