Hook into create_category

Question

I'm trying to in some way hook into when a new category is created. What I would like to do is to see the term and slug that was created and log them/email them. I have tried to hook in to create_category(). That only gives me an ID, not the term and slug. Would be great if someone could lead me on the right track.

Answer 1

You could use the get_term_by() function: http://codex.wordpress.org/Function_Reference/get_term_by

// get the category object
$category = get_term_by( 'id', $category_id, 'category');

// use the object to get your values
$name = $category->name;
$slug = $category->slug;

Does this help?
