The current_user_can_for_blog() WordPress PHP function checks if the currently logged in user has a specific capability for a specified site or blog.
Usage
Let’s say we want to check if the current user can edit posts on a specific blog. We can use the function like so:
$current_user_can_edit = current_user_can_for_blog($blog_id, 'edit_posts');
In this example, $current_user_can_edit will be a boolean that is true if the user has the ‘edit_posts’ capability for the blog specified by $blog_id, and false otherwise.
Parameters
- $blog_id (int): The ID of the site or blog you are checking the capability for.
- $capability (string): The name of the capability you want to check.
- $args (mixed, optional): Additional parameters, which usually start with an object ID.
