I need to run a function right after the user clicks "edit" on a custom post. {$old_status}_{$new_status} won't help because those and their relations fire after the custom post is edited. I need the function to run before the custom post is edited
Here's the detailed explanation: I have a list of members of a group, where the member custom post was created with the Pods plugin. My users are members of that group, and so have access to the list so they can create/modify/delete their data. Some of my users are barely computer literate, and easily confused. I don't want a user editing someone else's member data by mistake. So I want to compare the current user's user id to the member post's user id to make sure they match. If they don't, the user is denied access.
I have looked all over the WordPress site, and even looked through the hooks listed for WordPress 3.9 on Adam Brown's site. I'm afraid I'm stuck.
