You can also remove a taxonomy from a Post Type.
Manage Post Types columns
I will explain some examples of how to manage the columns for a Post Type.
- Register the Post Type.
- Manipulate the columns.
- Save the changes by re-registering the Post Type.
Add a new column
To add new columns to a Post Type you can do the following
Hide a column
To hide a column you can do the following
Set all columns
You can set all columns at once By doing this you must take a look at the Manage columns hook to prevent unwanted columns
Populate a column
To populate a column you can do the following
- You can only populate one column at once
- You must display the content and not return it
- You can't use this to populate a built-in column
You can also add new columns to existing and built in post types
Make a column sortable
To make a column sortable you can do the following
- You must make the column slug in key and value of the array
- The value must be the meta key to sort using
- Don't forget to populate the column before you make it sortable!
Order the columns
You may want to order the columns, even the native ones, do the following
- Set the final position, starting from 0
- Avoid duplicate and negative positions in your array!
Adding taxonomy filters to the edit screen
To add taxonomy filters to the edit screen you can do the following
- Add a list of taxonomies slugs
- The order is important because the filters will be displayed that order!
Hooks
