Inside of a WordPress category metabox or any custom taxonomy box for that matter there is a link with the text “+ Add New Category” is there a way this link can be removed preferably without resorting to JS or CSS hacks to hide it? A way to hide it using some kind of filter or action hook would be best.
If no action hook or filter method exists to remove it, I would be open to JS and CSS solutions as a last resort.
The reason I am doing this is because I have a WordPress installation integrated with Magento and I am creating and populating a custom taxonomy called “brands” with a list of brands from the Magento database so a post can be assigned to a brand. Obviously this means I don’t want users to be able to add in their own terms and only be able to choose the brands added in dynamically to keep it in-sync with Magento.
Thank you.
The default metaboxes are registred in the file
wp-admin/includes/meta-boxes.php. There you can find the functionpost_categories_meta_box()which will generate the taxonomy metabox. Currently there is no hook available to filter the output. But you can do one of the following:remove_meta_box()to remove the existing category metabox and register your own withadd_meta_box(). Copy&Past the existing code to your new metabox function and remove the code block from line345to367.edit_termscapability from your user roles withremove_cap(). If you look in the metabox function, on line345you can see an if-statement which checks if the user has the capabilityedit_terms. If so, the+ Add New XYwill be displayed. Problem here, the name of the capability is dynamic and could be anything. If someone registers a taxonomy with a different capability naming, this will probably not work (untested).
