Hi Pavlo, MARC as a format is not thought to carry executable code. Any code you add will be escaped for display as Koha assumes that < > and other characters are supposed to be displayed as they were entered. I'd recommend taking a look at how some of the other similar features are implemented in Koha where only the URL and Mime type or similar are catalogued and the other parts of the code are handled on template level. For example see the HTLM5* system preferences: https://koha-community.org/manual/20.05/en/html/systempreferences.html?highl... Hope this helps, Katrin On 23.09.20 15:29, Pavlo Bobesiuk wrote:

Hi everyone. Someone tried to add code of embed book to marc record and display it in the opac html5 media player? I have an idea to convert the first pages of books into flipbooks ( www.anyflip.com) and put code in marc record to be able to read them in opac media player. For example I would like to add this code:

<iframe style="width:550px;height:350px" src=" http://online.anyflip.com/mepon/fath/" seamless="seamless" scrolling="no" frameborder="0" allowtransparency="true" allowfullscreen="true" ></iframe>

to marc record of some book in 856u field, but in opac i see only code, I don't see frame with flip book. help me please realize this idea
