Hyphens are causing a blank result

I’m having issues with hyphens in my slugs from a tutorial I’m trying to go through… http://wp.tutsplus.com/tutorials/theme-development/create-a-quicksand-portfolio-with-wordpress/ and I’m having a problem when my client uses hyphens in the category. The category is blank when the client puts in a hyphen for some reason. Otherwise everything else is working perfectly!

Has anyone else ran into this problem? I’m thinking its a js problem but am uncertain as I am not receiving any console errors at all. So I’m not for sure how to debug.

  1. why not use term_id with any desired prefix: $term->term_id. In this case You will have unique identifier and less possibility to breake something.

    final version could be:

    $term_list .= '<li><a href="javascript:;" class="sort_by_term_'. $term->term_id .'">' . $term->name . '</a></li>';

    will produce something like this:

    <li><a href="javascript:;" class="sort_by_term_1234568">some long name with more words</a></li>
