This question came up on the Koha mailing list today: How can I add a Koha login form to my library’s web site? Luckily it’s really simple. The image here is of the one we added one to our site.
Everything you need to know about how to do it is right on your Koha OPAC home page. Just view the source for the login box and copy it! Here’s the simple version, adapted right from the source:
<form method="post" action="http://path.to.your.opac/cgi-bin/koha/opac-user.pl"> <label for="userid">Login:</label> <label for="password">Password:</label> </form>
The only thing you’d need to change to make that snippet work for you is the path.to.your.opac part. Replace that with the full URL of your Koha OPAC, e.g. http://acpl.kohalibrary.com.
You could even do the same for the staff client, for instance if you wanted your users to be able to log into the Koha staff client from your library’s intranet:
<form method="post" action="http://path.to.your.staff.client"> <label for="userid">Username:</label> <label for="password">Password:</label> </form>
Of course I wouldn’t recommend putting a login form for your staff client anywhere in public view. Note that using that form will log you in to your default library. If you wanted to give your users the option of logging into a different library you’d have to reproduce the full <select> tag from your staff client’s login page. View the source to find it.
