On the wordpress admin edit posts page, I want to display some custom content and script, underneath the meta box.
I want to hand code this as the various plugins I could use (advanced custom fields for instance) take too much control away, and I don't need an actual field to be saved.
So for example, I want to add this to the edit posts page:
That's pretty much it. Nothing fancy or that contains any editable content.
What hook or function do I need to use to achieve this?
Any help greatly appreciated
