I've whipped up a BB Code using their modern HTML5 embedding method (rather than the Flash-based one in this thread). This has been tested on both vb3 and vb4.
Title: Mixcloud
BB Code Tag Name: mixcloud
Replacement:
Code:
<iframe width="400" height="120" src="https://www.mixcloud.com/widget/iframe/?feed={param}&hide_cover=1&light=1" frameborder="0"></iframe>
Example: [mixcloud]https://www.mixcloud.com/spartacus/party-time/[/mixcloud]
Description: Embeds a Mixcloud player widget. Use the full Mixcloud URL in the tag. For example,
https://www.mixcloud.com/spartacus/party-time/
Use {option}: No
Remove Tag if Empty: Yes (and everything below this option set to Yes also).
You can change the size of the player by adjusting the iframe's width and/or height. If you want a dark-themed player, you can change "light=1" to "light=0".
