WP Query Obj: Set value to be unequal | Hide media by admin

Question

I would like to hide all media uploaded by the admin.

I've found an answer to this question to be pretty close. Except that the query returns all media uploaded by a specific (current) user, instead of excluding all by a specific user.

[...]
if( !current_user_can('delete_pages') )
    $wp_query_obj->set('author', $current_user->id );
[...]

Q: Is it possible to modify the wp_query_obj to exclude all posts by a specific user?

Answer 1

The method is similar, just exclude the author by prefixing the id with a minus sign:

$wp_query_obj->set( 'author', '-1' );

See WP_Query for a full list of query arguments.
