WC Custom Query Pagination Problem

Hi Guys,

I’m trying to pass a parameter on the URL of a page without much success. Here’s what my URL looks like now: http://benronperfume.flywheelsites.com/maincat/?cat=women-testers
http://benronperfume.flywheelsites.com/maincat/?cat=mens-testers

But when trying to page up, its all breaks up obviously because the lack of formatting.

Ultimetly I would like to have something like
http://benronperfume.flywheelsites.com/maincat/women-testers/

with pagination passing like:
http://benronperfume.flywheelsites.com/maincat/women-testers/1/
http://benronperfume.flywheelsites.com/maincat/women-testers/2/

But I don’t know how to mess around with the permalinks to create that.
Any help will be greatly appreciated!

here’s my pagination code:

/* Pagination */

function custom_pagination($numpages = '', $pagerange = '', $paged='') {

  if (empty($pagerange)) {
    $pagerange = 2;
  }

  global $paged;
  if (empty($paged)) {
    $paged = 1;
  }
  if ($numpages == '') {
    global $wp_query;
    $numpages = $wp_query->max_num_pages;
    if(!$numpages) {
        $numpages = 1;
    }
  }

  $pagination_args = array(
    'base'            => get_pagenum_link(1) . '%_%',
    'format'          => '/page/%#%/',
    'total'           => $numpages,
    'current'         => $paged,
    'show_all'        => False,
    'end_size'        => 1,
    'mid_size'        => $pagerange,
    'prev_next'       => True,
    'prev_text'       => __('«'),
    'next_text'       => __('»'),
    'type'            => 'plain',
    'add_args'        => false,
    'add_fragment'    => ''
  );

  $paginate_links = paginate_links($pagination_args);

  if ($paginate_links) {
    echo "<nav class='tw-pagination'>";
      echo "<span class='page-numbers page-num'>Page " . $paged . " of " . $numpages . "</span> ";
      echo $paginate_links;
    echo "</nav>";
  }

}
