Recordset Sort Problem

Hi.  I am trying to sort a recordset.  I had a friend work on some javascript and while I think we've made some progress it still isn't working.  I am trying to sort by price - ASC or DESC or discount - ASC or DESC.  I would like to keep all the options in one drop down box due to space constraints on my page.  Please note that the recordset query was created by Dreamweaver and there is a repeat-region at work here as well.

Notice that I am getting the Order By variables in the recordset (order and sort) but not even sure if I need this.

The form action needs to maintain the original variable parameters of category and subcategory (this works) and then apply the sort (this is not working).

I only included the code that I think is applicable - please let me know if you need more information.   Thank you for your help; this newbie has been working at this for over a week now and any help is greatly appreciated.

The Recordset Query:
 
mysql_select_db($database_golena_IDBdb, $golena_IDBdb);
$query_rsProductsDiscount = sprintf("SELECT ((IDBdb.retail_price-IDBdb.price)/IDBdb.retail_price) AS discount, IDBdb.name, IDBdb.shortDescription, IDBdb.merchant_display, IDBdb.retail_price, IDBdb.price, IDBdb.url, IDBdb.thumbnail, IDBdb.productID, IDBdb.category, IDBdb.category_display, IDBdb.subcategory, IDBdb.subcategory_display, IDBdb.merchant FROM IDBdb WHERE (((IDBdb.subcategory)='%s')) ORDER BY %s %s", $colname2_rsProductsDiscount,$orderby_rsProductsDiscount,$sortby_rsProductsDiscount);
$query_limit_rsProductsDiscount = sprintf("%s LIMIT %d, %d", $query_rsProductsDiscount, $startRow_rsProductsDiscount, $maxRows_rsProductsDiscount);
$rsProductsDiscount = mysql_query($query_limit_rsProductsDiscount, $golena_IDBdb) or die(mysql_error());
$row_rsProductsDiscount = mysql_fetch_assoc($rsProductsDiscount);
 
if (isset($_GET['totalRows_rsProductsDiscount'])) {
  $totalRows_rsProductsDiscount = $_GET['totalRows_rsProductsDiscount'];
} else {
  $all_rsProductsDiscount = mysql_query($query_rsProductsDiscount);
  $totalRows_rsProductsDiscount = mysql_num_rows($all_rsProductsDiscount);
}
$totalPages_rsProductsDiscount = ceil($totalRows_rsProductsDiscount/$maxRows_rsProductsDiscount)-1;
 
The Form:
 
<form name="SortForm" method="get" action="">
                                              <select name="Order By">
											 
                                                <option value selected="Price ASC">Sale Price - Low to High
                                                </option>
                                                <option value="Price DESC">Sale Price - High
                                                to Low</option>
                                                <option value="Discount ASC">Discount Low
                                                to High</option>
                                                <option value="Discount DESC">Discount -
                                                High to Low</option>
                                              </select>
					 <input type="hidden" name="category" value="<?php echo htmlentities($_GET['category']) ?>">
					 <input type="hidden" name="subcategory" value="<?php echo htmlentities($_GET['subcategory']) ?>">                                              
					<input type="submit" name="Submit" value="go">
                                            </form>

immediately after:

$query_limit_rsProductsDiscount = sprintf(....);
 
put:
echo "<pre>\n{$query_limit_rsProductsDiscount}</pre>";
 
what does it print? What you posted does not reveal much about:
$colname2_rsProductsDiscount
$orderby_rsProductsDiscount
$sortby_rsProductsDiscount

It prints:

SELECT ((IDBdb.retail_price-IDBdb.price)/IDBdb.retail_price) AS discount, IDBdb.name, IDBdb.shortDescription, IDBdb.merchant_display, IDBdb.retail_price, IDBdb.price, IDBdb.url, IDBdb.thumbnail, IDBdb.productID, IDBdb.category, IDBdb.category_display, IDBdb.subcategory, IDBdb.subcategory_display, IDBdb.merchant FROM IDBdb WHERE (((IDBdb.subcategory)='Outdoor-Patio-Cushions')) ORDER BY price ASC LIMIT 0, 10

Also, here are the two queries for order and sort:

$sortby_rsProductsDiscount = "ASC";
if (isset($_GET['sort'])) {
  $sortby_rsProductsDiscount = (get_magic_quotes_gpc()) ? $_GET['sort'] : addslashes($_GET['sort']);
}

$orderby_rsProductsDiscount = "price";
if (isset($_GET['order'])) {
  $orderby_rsProductsDiscount = (get_magic_quotes_gpc()) ? $_GET['order'] : addslashes($_GET['order']);

>>Also, here are the two queries for order and sort:
But  that does not make use of the select list to do the ordering, which is what you want.

On your HTML form, this is NOT correct:
<option value selected="Price ASC">Sale Price - Low to High</option>
 
it should be:
<option selected value="Price ASC">Sale Price - Low to High</option>
 
Also, rename your select to:
 <select name="OrderBy">
 
Notice that it does not have a space.  Then check if OrderBy exists and  is so, use that instead:
 
The Recordset Query:
 
mysql_select_db($database_golena_IDBdb, $golena_IDBdb);
if( isset($_REQUEST['OrderBy']) && !empty($_REQUEST['OrderBy']) )
	$query_rsProductsDiscount = sprintf("SELECT ((IDBdb.retail_price-IDBdb.price)/IDBdb.retail_price) AS discount, IDBdb.name, IDBdb.shortDescription, IDBdb.merchant_display, IDBdb.retail_price, IDBdb.price, IDBdb.url, IDBdb.thumbnail, IDBdb.productID, IDBdb.category, IDBdb.category_display, IDBdb.subcategory, IDBdb.subcategory_display, IDBdb.merchant FROM IDBdb WHERE (((IDBdb.subcategory)='%s')) ORDER BY %s", $colname2_rsProductsDiscount,$_REQUEST['OrderBy']);
else
	$query_rsProductsDiscount = sprintf("SELECT ((IDBdb.retail_price-IDBdb.price)/IDBdb.retail_price) AS discount, IDBdb.name, IDBdb.shortDescription, IDBdb.merchant_display, IDBdb.retail_price, IDBdb.price, IDBdb.url, IDBdb.thumbnail, IDBdb.productID, IDBdb.category, IDBdb.category_display, IDBdb.subcategory, IDBdb.subcategory_display, IDBdb.merchant FROM IDBdb WHERE (((IDBdb.subcategory)='%s')) ORDER BY %s %s", $colname2_rsProductsDiscount,$orderby_rsProductsDiscount,$sortby_rsProductsDiscount);
 
$query_limit_rsProductsDiscount = sprintf("%s LIMIT %d, %d", $query_rsProductsDiscount, $startRow_rsProductsDiscount, $maxRows_rsProductsDiscount);
$rsProductsDiscount = mysql_query($query_limit_rsProductsDiscount, $golena_IDBdb) or die(mysql_error());
$row_rsProductsDiscount = mysql_fetch_assoc($rsProductsDiscount);
 
if (isset($_GET['totalRows_rsProductsDiscount'])) {
  $totalRows_rsProductsDiscount = $_GET['totalRows_rsProductsDiscount'];
} else {
  $all_rsProductsDiscount = mysql_query($query_rsProductsDiscount);
  $totalRows_rsProductsDiscount = mysql_num_rows($all_rsProductsDiscount);
}
$totalPages_rsProductsDiscount = ceil($totalRows_rsProductsDiscount/$maxRows_rsProductsDiscount)-1;
 
The Form:
 
<form name="SortForm" method="get" action="">
                                              <select name="OrderBy">
                                                <option selected value="Price ASC">Sale Price - Low to High</option>
                                                <option value="Price DESC">Sale Price - High to Low</option>
                                                <option value="Discount ASC">Discount Low to High</option>
                                                <option value="Discount DESC">Discount - High to Low</option>
                                              </select>
                                         <input type="hidden" name="category" value="<?php echo htmlentities($_GET['category']) ?>">
                                         <input type="hidden" name="subcategory" value="<?php echo htmlentities($_GET['subcategory']) ?>">                                              
                                        <input type="submit" name="Submit" value="go">
                                            </form>
