Excluding categories by slug from the Category Widget

    I have this bit of code that works wonderfully well for removing categories from the sidebar category widget. However, I can only use IDs and I would much rather have it use the category slug. I’m not a developer, and I’ve wasted a good few hours hacking around trying to make it work with other code i have that uses slugs for things, but I just don’t know enough to get there. If anyone could help, that would be fabulous, and I believe this could be quite useful to others as well.

    <?php
function exclude_widget_categories($args){
$exclude = "1"; // The IDs of the excluding categories
$args["exclude"] = $exclude;
return $args;
}
add_filter("widget_categories_args","exclude_widget_categories");
?>

    get_term_by()
    http://codex.wordpress.org/Function_Reference/get_term_by

    example:

    $cat = get_term_by( 'slug', 'slug-to-exclude', 'category' );
$exclude = $cat->term_id; // The IDs of the excluding categories

    Wonderful. That works extremely well. Can I bother you to ask how I would exclude multiple categories in that snippet?

    function exclude_widget_categories( $args ){

$excludes = array( 'slug-1', 'cat-slug2', 'another-catslug' ); //array with category slugs to be excluded
$cat_ids = array();
foreach( $excludes as $cat_slug ) {
  $cat = get_term_by( 'slug', $cat_slug, 'category' );
  if( $cat ) $cat_ids[] = $cat->term_id;
}
$exclude = implode( ',', $cat_ids ); // The IDs of the excluding categories
if( $cat_ids ) $args["exclude"] = $exclude;

return $args;
}

add_filter("widget_categories_args","exclude_widget_categories");
