How to add content to the content area programmatically


How can I add specific content to a page content area programmatically.

I do not want to use a filter but actually add text to the content area for a page so it is shown and saved as a part of the content area.

Example, let's say I have created a function which grab some custom meta info about the page. Then I want to create a function that automatically takes that value and adds it to the content area ( and gives me the option to edit it in the back-end ).

Haha, does it make any sense? :slight_smile:
