[UPDATE 2023] Use the default combination image, with a non-zero quantity, as the cover image in Prestashop

Publié par David Sprang le 21 septembre 202321 septembre 2023

Update 2023

I was really hanging over a problem with a website. In fact, the products have a lot of combination (colors). Because it is related with fashion accessories. The thing is, some colors were simply not remade because of the complexity of certain material. So, a lot of products miniature in product-list were displaying « out-of-stock » or « Product available with different options » and it will never change!

Before SQL script

After SQL script

I just thought it would be interesting to create an Add-on to the SQL script I designed on my blog, which would be:

Check all the products combinations which are the default combination and have a stock quantity of zero
- Set them to not the default combination
- Use the combination of this product with the max stock quantity as default
Use the old SQL script: set the cover images as the images of the default combination

Introduction

You can import the default image of a product with CSV import, but you cannot import the cover image. For example, it is very important to select a good bunch of images for the products with different colors. If you sell t-shirts and all the cover images show white t-shirts, your webshop will lack of identity.

The easiest way is to import the default image and use a SQL request to set the same cover image than the default image.

Set the default combination images as cover images

First, you need to have set all the default image in your catalog. You can do this automatically by importing a CSV file.
Open your database (for example by PhpMyAdmin)
Create backup of your database for safety (export data and structure)
Open SQL tab and perform queries from this file (change ‘ps_’ to your prefix):

-- Update cover attributes in ps_image and ps_image_shop tables
START TRANSACTION;

-- Reset covers in ps_image and ps_image_shop
UPDATE ps_image SET cover = NULL;
UPDATE ps_image_shop SET cover = NULL;

-- Set cover attributes based on default_on
UPDATE IGNORE ps_image
SET cover = 1
WHERE ps_image.id_image IN (
 SELECT ps_product_attribute_image.id_image
 FROM ps_product_attribute
 INNER JOIN ps_product_attribute_image
 ON ps_product_attribute.id_product_attribute = ps_product_attribute_image.id_product_attribute
 AND ps_product_attribute.default_on = 1
);

UPDATE IGNORE ps_image_shop
SET cover = 1
WHERE ps_image_shop.id_image IN (
 SELECT ps_product_attribute_image.id_image
 FROM ps_product_attribute
 INNER JOIN ps_product_attribute_image
 ON ps_product_attribute.id_product_attribute = ps_product_attribute_image.id_product_attribute
 AND ps_product_attribute.default_on = 1
);

COMMIT;

-- Update cover attributes in ps_image and ps_image_shop tables

START TRANSACTION;

-- Reset covers in ps_image and ps_image_shop

UPDATE ps_image SET cover = NULL;

UPDATE ps_image_shop SET cover = NULL;

-- Set cover attributes based on default_on

UPDATE IGNORE ps_image

SET cover = 1

WHERE ps_image.id_image IN (

SELECT ps_product_attribute_image.id_image

FROM ps_product_attribute

INNER JOIN ps_product_attribute_image

ON ps_product_attribute.id_product_attribute = ps_product_attribute_image.id_product_attribute

AND ps_product_attribute.default_on = 1

);

UPDATE IGNORE ps_image_shop

SET cover = 1

WHERE ps_image_shop.id_image IN (

SELECT ps_product_attribute_image.id_image

FROM ps_product_attribute

INNER JOIN ps_product_attribute_image
