Do Not Display Subcategories With 0 Products

[Lucky#13]

Good Afternoon All.

 

I have been searching around for quite sometime, and my php is beginner at best. I have a somewhat custom store, so I am unsure if this is the code that I need to look at. I am trying to disable subcategories with no product from showing. I think this is the code but I am unsure of how to change it. Please help!! Thanks.

 

<?   // ---- CATEGORIES 
 function tep_show_category($counter) {
global $tree, $categories_string, $cPath_array;

  if(!$tree[$counter]['level']){			   

$categories_string .= $categories_string ? '<tr><td height=3></td></tr>' : '';			 

$categories_string .= '<tr><td class=ch3><img src=images/m16.gif width=3 height=5 align=absmiddle>   <a class=ml3  href=';

if ($tree[$counter]['parent'] == 0) {
  $cPath_new = 'cPath=' . $counter;
} else {
  $cPath_new = 'cPath=' . $tree[$counter]['path'];
}
$categories_string .= tep_href_link('index.php', $cPath_new) . '>';
// display categry name
$categories_string .= $tree[$counter]['name'];
$categories_string .= '</a></td></tr><tr><td height=3></td></tr>';

  }else{  // SUBCATEGORY

$categories_string .= '<tr><td> '; 

for($i=0;$i<$tree[$counter]['le vel'];$i++)
 $categories_string .= '   ';

$categories_string .= ' - <a class=ml3 style="font-weight:normal"  href=';   
if ($tree[$counter]['parent'] == 0) {
  $cPath_new = 'cPath=' . $counter;
} else {
  $cPath_new = 'cPath=' . $tree[$counter]['path'];
}
$categories_string .= tep_href_link('index.php', $cPath_new) . '>';
// display category name
$categories_string .= $tree[$counter]['name'];
$categories_string .= '</a></td></tr><tr><td height=3></td></tr>';
  }
