I would like to allow contributors to upload media by using the following code added to functions.php. But the Add Media Button still doesn't show up.

// Allow Contributors to Add Media
if ( current_user_can('contributor') && ! current_user_can('upload_files') ) {
    add_action('admin_init', 'allow_contributor_uploads');
    function allow_contributor_uploads() {
       $contributor = get_role('contributor');
       $contributor->add_cap('upload_files');
    }
}

Try changing current_user_can('contributor') to current_user_can('edit_posts'). According to the Codex, 'Passing role names to current_user_can() is discouraged as this is not guaranteed to work correctly.'

I would try surrounding your conditional expression in brackets, just to make sure it's getting parsed properly:

if ( current_user_can('edit_posts') && ! current_user_can('upload_files') ) { add_action( 'admin_init', 'allow_contributor_uploads' ); } function allow_contributor_uploads() { $contributor = get_role('contributor'); $contributor->add_cap('upload_files'); }
