HTML description


Recommended Posts


I tried to find a way on how to add HTML description under the video player.

I am using hotlinking for video files and when i import videos with Text block i want to add a HTML description ( with link inside) that should appear under the video player.

I tried to find a way , read the documentation but could not find a fix for this issue i have.

As you can see in the image attached, the html code from description is not recognized.

Can you please advise

Thank you

For security reasons all HTML tags are escaped by default, so that users cannot inject harmful code when uploading videos.

If your project doesn't allow users to upload videos, you can make video description field support HTML tags by editing Website UI -> Pages -> View Video page -> video_view block template.

Find this:


Or in older theme version it may look like this:



Change to this:

It is possible to allow HTML for users as well, but there are 2 notes on that:

1) You should be using HTML Purifier library to filter harmful HTML code. This is supported in KVS, but we don't bundle the library. You should download it yourself and put its files into /admin/include/htmlpurifier directory (without version). Then in template you can use this:


It is configured with default settings that should allow removing all harmful code.

2) If you want to enable WYSIWYG editor for users, this is not supported in any KVS theme, so you have to attach them yourself. This should be pretty straightforward by reading theie documentation and it doesn't matter whether the site is KVS, or any other site.
