Product by categories Id

With powerstore2 I was able to display my products using category Id below is the code
"SELECT *, (ProductStock - (SELECT Coalesce(Sum(DetailQuantity),0) FROM orderdetails INNER JOIN orders ON OrderID = DetailOrderID WHERE DetailProductID = ProductID AND OrderDate > ProductUpdateDate)) AS NumLeft, (SELECT MAX(ProductPrice) FROM products as prod2 INNER JOIN productoptions ON productoptions.ProductID = prod2.ProductID WHERE productoptions.GroupingID = products.ProductID AND prod2.ProductLive <> 0) AS TopPrice, (SELECT MIN(ProductPrice) FROM products as prod2 INNER JOIN productoptions ON productoptions.ProductID = prod2.ProductID WHERE productoptions.GroupingID = products.ProductID AND prod2.ProductLive <> 0) AS BottomPrice FROM products LEFT OUTER JOIN productcategories ON ProductCategoryID = CategoryID WHERE ProductLive <> 0 AND COALESCE((SELECT GroupingID FROM productoptions WHERE productoptions.ProductID = products.ProductID LIMIT 1), ProductID) = ProductID AND products.ProductCategoryID = 16 ORDER BY products.ProductID DESC"

but now I've upgraded to powerstore3 I've tried to add filter the productcategory to ps3_categories.CategoryID =16

but am having these error Unknown column 'ps3_categories.CategoryID' in 'order clause'

Which page are you trying to add the filter to? Is it the Products_Results.php page?

yes, Products_Results.php page

The ps3_categories table is not the table being selected from in the products query, so you can't use the categories to order the products. I believe you'd want to use the GroupingID for this purpose.

thnaks, please explain more cause I dont know about the GroupID, please it possible to help me out with the filtering code to be added unto it?

In PowerStore v3, you can add a product which does not belong to any category, which is why the category id column does not exists in the products table any more.

Instead, You might want to update the links to your product results page to include the category in the url, for example, you could have a link as follow:

Products_Results.php?Search=1&ProductCategoryID[]=1

or

Products_Results.php?Search=1&ProductCategoryID[]=2

Thank you, I type these in the browser Products_Results.php?ProductCategoryID[]=1
or

Products_Results.php?CategoryID[]=1

and the result brought out all products in the database.

but actually in my database in ps3_cetegories i have

CategoryID CategoryName CategoryParent
1 PLAYSETS 0
2 CLASSROOM STORAGE 0
3 BOOK STORAGE 0
4 TOY STORAGE 0

or do i have to filter through my product result page? thank you

You will just need to add an additional parameter as follow:

?Search=1&ProductCategoryID[]=1

if you click on the link i sent you in a browser, you will see the second parameter (Search=1)

thank you but I still dont know where to put the ?Search=1&ProductCategoryID[]=1, do I have to put it on the product result page? When I put it below is the code but it came up with error

"SELECT * , coalesce((select ps3_productoptions.GroupingID from ps3_productoptions WHERE ps3_productoptions.ProductID = ps3_products.ProductID limit 1),ps3_products.ProductID) AS GroupingID FROM ps3_products WHERE ProductLive = 1 GROUP BY GroupingID ORDER BY ProductName ?Search=1&ProductCategoryID[]=1";

ERROR
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?Search=1&ProductCategoryID[]=1 LIMIT 0, 10' at line 1

or am i placing it in the wrong section?


And if i placed it on the link Products_Results.php?Search=1&ProductCategoryID
it gives me below error

Warning: implode() [function.implode]: Invalid arguments passed in /home/thearkea/public_html/Products_Results.php on line 84
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')) GROUP BY GroupingID ORDER BY ProductName LIMIT 0, 10' at line 1

thanks

You will need to add that to the link to the product result page. So the url needs to be:

Products_Results.php?Search=1&ProductCategoryID[]=1
