I have several blogs with hundreds of categories/subcategories and got tired of manually creating them by hand. Though there are a couple bulk category plugins - there are none that worked exactly as I wanted.
I build the front end and the code to process the uploaded file. All appears to work - the subcategories are added to the selected category in the database and the total pages of categories increase but they don't show on the category page - though they do in the category box when creating a post.
Now, if the category I've selected as a parent already has at least one subcategory, everything works.
Obviously there is another database call I need to make to create a subcategory relationship?
Any thoughts would be great.
