Fix for undefined index plugin errors

Well that got mangled. Let’s try this.

// Create our drop-down category listing, using all the latest & greatest WordPress things
function tc_ctf_restrict_manage_posts() {

    global $wp_query;

    $filters = tc_ctf_get_filters();

    foreach( $filters as $tax_slug ) {

        $taxonomy = get_taxonomy( $tax_slug );

		$value = array_key_exists($tax_slug, $wp_query->query_vars) ? $wp_query->query_vars[$tax_slug] : '';

		$term = get_term_by( 'slug', $value, $taxonomy->name );

		$term_id = $term ? $term->term_id : '';

		wp_dropdown_categories(
			array(
				'show_option_all'   => __("Show All " . $taxonomy->labels->name ),
				'taxonomy'          => $tax_slug,
				'name'              => $tax_slug,
				'hide_empty'        => false,
				'orderby'           => 'name',
				'order'             => 'ASC',
				'selected'          => $term_id
			)
		);
    }
}

One more tweak (end of that same file):

// loop through each of the requested taxonomies
    if ( $pagenow == 'edit.php' ) {
        foreach ( $tax_queries as $tax_query ) {
            $term = get_term_by( 'id', $tax_query['terms'][0], $tax_query['taxonomy'] );
            $slug = $term ? $term->slug : '';
            $query_vars[$tax_query['taxonomy']] = $slug;
        }
    }

Thanks for the pull request, guys. I’ve merged the code and submitted it to the repo. Please let me know if you find any other issues. If not, just mark this thread as “resolved.”

Thanks.
