List products in order of price

[ccoder]

Hi,

 

Simple question I think, when a catagory is displayed the products are automaticaly listed alphabetically. I want them listed lowest prices to highest prices.

 

Which file or setting do I alter?

 

Thanks

It will be an "order by" in the query where it states order by product name you will want to change it to price. I think it is right here in the index.php:

$listing_sql = "select " . $select_column_list . " p.products_id, p.manufacturers_id, p.products_price, p.products_tax_class_id, IF(s.status, s.specials_new_products_price, NULL) as specials_new_products_price, IF(s.status, s.specials_new_products_price, p.products_price) as final_price from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_MANUFACTURERS . " m, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c left join " . TABLE_SPECIALS . " s on p.products_id = s.products_id where p.products_status = '1' and p.manufacturers_id = m.manufacturers_id and m.manufacturers_id = '" . (int)$HTTP_GET_VARS['filter_id'] . "' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '" . (int)$languages_id . "' and p2c.categories_id = '" . (int)$current_category_id . "'";
     } else {
// We show them all
       $listing_sql = "select " . $select_column_list . " p.products_id, p.manufacturers_id, p.products_price, p.products_tax_class_id, IF(s.status, s.specials_new_products_price, NULL) as specials_new_products_price, IF(s.status, s.specials_new_products_price, p.products_price) as final_price from " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_PRODUCTS . " p left join " . TABLE_MANUFACTURERS . " m on p.manufacturers_id = m.manufacturers_id, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c left join " . TABLE_SPECIALS . " s on p.products_id = s.products_id where p.products_status = '1' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '" . (int)$languages_id . "' and p2c.categories_id = '" . (int)$current_category_id . "'";
     }
   }

   if ( (!isset($HTTP_GET_VARS['sort'])) || (!ereg('[1-8][ad]', $HTTP_GET_VARS['sort'])) || (substr($HTTP_GET_VARS['sort'], 0, 1) > sizeof($column_list)) ) {
     for ($i=0, $n=sizeof($column_list); $i<$n; $i++) {
       if ($column_list[$i] == 'PRODUCT_LIST_NAME') {
         $HTTP_GET_VARS['sort'] = $i+1 . 'a';
         $listing_sql .= " order by pd.products_name";
         break;
       }
     }
   } else {
     $sort_col = substr($HTTP_GET_VARS['sort'], 0 , 1);
     $sort_order = substr($HTTP_GET_VARS['sort'], 1);
     $listing_sql .= ' order by ';
     switch ($column_list[$sort_col-1]) {
       case 'PRODUCT_LIST_MODEL':
         $listing_sql .= "p.products_model " . ($sort_order == 'd' ? 'desc' : '') . ", pd.products_name";
         break;
       case 'PRODUCT_LIST_NAME':
         $listing_sql .= "pd.products_name " . ($sort_order == 'd' ? 'desc' : '');
         break;

However, you'll need to work it into the query from the top and its a bit too complex for me to help you more. You can see near the bottom where it says "order by pd.products_name" and then below that where it allows a switch from ascending to descending. Find someone good at complex queries (ok, complex to me) and they will help.
