Products Grid: Adding a column 'nb of products sales in the last month'


Target

We would like to add a column displaying the number of sales for the last month.

We will then be able to:

- use filters in the grids to find the most sold products and eventually remove unsold products

- export quickly the products grid including this field to work on an Excel spreadsheet

 

Setup

To add the field to the list of available fields for your products grids, click on the add.png in the 'Add a field' panel and enter the following information:

What is the field ID?: nb_sale_1_month

 

SC creates the field, you now need to populate the grid with:

Field name: Nb sales for the last month
Table: enter: special
Type: just displayed
Refresh combinations: No

 

From the Advanced Properties panel on the right handside:
 

- select the menu SQLSelect and enter:

return ',(SELECT SUM(od.product_quantity) AS nb
            FROM `'._DB_PREFIX_.'order_detail` od
            INNER JOIN `'._DB_PREFIX_.'orders` o ON (od.id_order = o.id_order)
            WHERE od.product_id = p.id_product
            AND o.valid=1
            AND o.current_state IN (4,5)
            AND o.date_add >= (SELECT DATE_ADD("'.date("Y-m-d").' 00:00:00", INTERVAL -1 MONTH))
            LIMIT 1) AS nb_sale_1_month';

 

Here we look for valid orders with a status 4 or 5 (refer to PrestaShop > Orders > Status) with a date of at least one month. You then duplicate this field and modify the line before last with INTERVAL -3MONTH)) to get the number of sales for the past 3 months.

 

Exit the editing window.

The new field is now present in the list of available fields and you can add it to your product grids.
