I am developing a free plugin for wordpress and I have a question when uninstalling the plugin. The plugin creates a custom post type, and some custom fields that are saved in postmeta. I have seen that there are several functions, but I get a little messed up.
My question is: If I want to eliminate these custom fields from the bbdd, the function I should use is delete_post_meta ()?
I ask because I've also seen the delete_metadata () function, and they do the same, do not they?
Thanks for your time and help.
