I have recently built a plugin for Wordpress sort of Special Events & News listing. I have a listing page and then a detailed page for every news item. Now in the database I have set up 3 columns named meta_title, meta_description and meta_keywords. I also have All in one SEO plugin installed.
Is there a way how from within the plugin (from the loop where I am showing the content), I can say for example wp_page_meta = $meta_title or something similar?
As I found some tricks on how to do this by hacking the functions.php and header.php for the theme but this is not the right way.
You may want to check out the get_post_meta function in the codex and create custom meta boxes for each event, instead of dealing with the database directly. http://codex.wordpress.org/Function_Reference/get_post_meta
