I need to merge this:


    <?php
            if (is_category()) {
              $this_category = get_category($cat);
              if (get_category_children($this_category->cat_ID) != "") {
                echo '<h3 class="widget-title">Cities in ';
                 echo single_cat_title(); ;
                echo '</h3>';
                echo '<ul class="xoxo categories">';
                wp_list_categories('orderby=id&show_count=0&title_li=&use_desc_for_title=1&child_of='.$this_category->cat_ID);
                echo "</ul>";
              }
            }
            ?>



with this:


<?php // display categories list in 5 columns
                // Grab the categories - top level only (depth=1)
                 $get_cats = wp_list_categories( 'echo=0&title_li=&depth=1&show_count=1&exclude=1' );
                // Split into array items
                 $cat_array = explode('</li>',$get_cats);
                // Amount of categories (count of items in array)
                 $results_total = count($cat_array);
                // How many categories to show per list (round up total divided by 5)
                 $cats_per_list = ceil($results_total / 5);
                // Counter number for tagging onto each list
                 $list_number = 1;
                // Set the category result counter to zero
                 $result_number = 0;
            ?>
            <ul class="category_footer_post" id="cat-col-<?php echo $list_number; ?>">

                <?php
                    foreach($cat_array as $category) {
                    $result_number++;

                    if($result_number % $cats_per_list == 0) {
                    $list_number++;
                    echo $category.'</li>
                    </ul>

                    <ul class="category_footer_post" id="cat-col-'.$list_number.'">';

                } else { echo $category.'</li>'; } } ?>

            </ul>



so that I end up with a 5 column list of the sub categories for the currently viewed category




I've solved it, Praise the Lord

        <?php // display categories list in 5 columns
                // Grab the categories - top level only (depth=1)
                $this_category = get_category($cat);
                 $get_cats = wp_list_categories( 'echo=0&title_li=&depth=1&show_count=1&exclude=1&child_of='.$this_category->cat_ID);
                // Split into array items
                 $cat_array = explode('</li>',$get_cats);
                // Amount of categories (count of items in array)
                 $results_total = count($cat_array);
                // How many categories to show per list (round up total divided by 5)
                 $cats_per_list = ceil($results_total / 5);
                // Counter number for tagging onto each list
                 $list_number = 1;
                // Set the category result counter to zero
                 $result_number = 0;
            ?>
            <ul class="category_footer_post" id="cat-col-<?php echo $list_number; ?>">

                <?php
                    foreach($cat_array as $category) {
                    $result_number++;

                    if($result_number % $cats_per_list == 0) {
                    $list_number++;
                    echo $category.'</li>
                    </ul>

                    <ul class="category_footer_post" id="cat-col-'.$list_number.'">';

                } else { echo $category.'</li>'; } } ?>

            </ul>
