Question

I have a search form where user can search for products within their specified price range.
Wherein I have 2 input boxes 1 is for the starting range and the other is for the ending range.

I have 3 products stores in my database table. With prices 2300.0000, 1200.0000, 1000.5000 respectively.

Im having a problem with selecting values within the inputted price range. The problem is that, when I input values like

1. 100 starting range to 1100 ending range. The products with 1200.0000
   and 1000.5000 is being displayed instead of only the 1000.5000
   product.
2. 0 starting range to 1100 ending range or 1000.50 ending range. The
   products with 1200.0000 and 1000.5000 is being displayed instead of
   only the 1000.5000 product.
3. 1100 starting range. Only the product with 2300.0000 is being
   displayed instead of both 2300.0000 and 1200.0000. But when the
   starting values is less than or equal 500 all the 3 products is
   being displayed.

This is the code i am using.

function db_prepare_input($string)
{
    if (is_string($string)) {
        return trim(stripslashes($string));
    } elseif (is_array($string)) {
        reset($string);
        while (list($key, $value) = each($string)) {
            $string[$key] = db_prepare_input($value);
        }
        return mysql_real_escape_string($string);
    } else {
        return mysql_real_escape_string($string);
    }
}

$pricefrom_key = db_prepare_input(number_format($_GET['pricefrom'], 4, '.', ''));
$priceto_key = db_prepare_input(number_format($_GET['priceto'], 4, '.', ''));

// Price Range
if (!empty($_GET['pricefrom']) && !empty($_GET['priceto'])) {
    $price_range = " having price >= ".$pricefrom_key." and price <= ".$priceto_key;
}
elseif(empty($_GET['pricefrom']) && !empty($_GET['priceto']))
{
    $price_range = " having price >= 0 and price <= ".$priceto_key;
}

elseif(!empty($_GET['pricefrom']) && empty($_GET['priceto']))
{
    $price_range = " having price >= ".$pricefrom_key;
}

elseif(!empty($_GET['pricefrom']) && !empty($_GET['priceto']))
{
    $price_range = "";
}

$catglobal_sql = "select p.blog_id, p.global_category_id, p.products_id, p.products_currency, p.products_type, p.products_name, p.products_description, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_weight, p.products_status, p.products_tax_class_id, p.manufacturers_id, p.products_ordered, p.specials_new_products_price, p.specials_date_added, p.specials_last_modified, p.expires_date, p.date_status_change, p.status, p.display_product, case when (p.specials_new_products_price > 0 or p.specials_new_products_price != 0000-00-00 and p.expires_date > Now() and p.status != 0) then p.specials_new_products_price else p.products_price end price from ".TABLE_GLOBAL_PRODUCTS." p INNER JOIN ".TABLE_STORES." s ON s.blog_id = p.blog_id where MATCH (p.products_name,p.products_description) AGAINST ('%".$search_key."%') OR p.products_name like '%".$search_key."%' and s.countries_id = '168' ".$search_cat." and p.display_product = '1' and p.products_status = '1' ".$price_range." order by p.products_date_added DESC, p.products_name";

I tried, adding die($catglobal_sql); and the result is,

select p.blog_id, p.global_category_id, p.products_id, p.products_currency, p.products_type, p.products_name, p.products_description, p.products_quantity, p.products_model, p.products_image, p.products_price, p.products_date_added, p.products_last_modified, p.products_date_available, p.products_weight, p.products_status, p.products_tax_class_id, p.manufacturers_id, p.products_ordered, p.specials_new_products_price, p.specials_date_added, p.specials_last_modified, p.expires_date, p.date_status_change, p.status, p.display_product, case when (p.specials_new_products_price > 0 or p.specials_new_products_price != 0000-00-00 and p.expires_date > Now() and p.status != 0) then p.specials_new_products_price else p.products_price end price from wp_global_products_table p INNER JOIN wp_blogs s ON s.blog_id = p.blog_id where MATCH (p.products_name,p.products_description) AGAINST ('%cotton%') OR p.products_name like '%cotton%' and s.countries_id = '168' and p.products_currency = 'php' and p.display_product = '1' and p.products_status = '1' and p.products_type = 'a' having price >= 0 and price <= 1200.0000 order by p.products_date_added DESC, p.products_name

What seems to be the problem??

Answer 1

I have found the problem.. Its on the case.. i have modified it to case when p.specials_new_products_price >= 0.0000 and p.expires_date > Now() and p.status != 0 then p.specials_new_products_price else p.products_price end price
