I feel like I have been searching the web dry about this.
When using CKeditor with PHP, you are still only allowed one instance open with same name.
If you have more you get:
The instance "yourname" already exists.
error.
I see a lot of people solving this by closing/destroying the instance with jquery or javascript.
This guy is having the same problem: https://stackoverflow.com/questions/8839576/ckeditor-cannot-call-method-destroy-of-undefined
One solution is to leave the name blank, then you can create as many instance as you like. But this is not a good solution for me, as I need the name to send $_post.
So does anyone know how to destroy/close an instance in CKeditor with PHP?
EDIT: Fixed it in no time switching to javascript: CKEditor instance already exists
