I have add a extra colmn in WP_posts mysql database.
Is there a way to show and add this extra column in my custom post type.
I don't want to use meta because it is placed in another table "WP_postmeta". I want to have al the content in one table.
The product information is imported from a .CSV this is why I want it in one table.
When I google for "Show and add textarea box in a custom post type" i only get the way to fix it with WP_postmeta. https:// wptheming.com/2010/08/custom-metabox-for-post-type/
Is there a way to fix this for the WP_posts table.
