I have a custom post type which has multiple wysiwyg editors within the same post. When creating a new post of this type, I wish to have default text in some of these wysiwyg editors but not in the main wysiwyg editor. Using the "default_content" filter hook, I was able to add text to the main editor, but was unable to reach the other wysiwyg editors.
How would I go about adding text to the non-main wysiwyg editors? Is there a hook to reach all wysiwyg editors and then I'd need to filter which ones are not the main wysiwyg editor?
