We would like to add a column displaying a feature associated to a product within an order.
To add the field to the list of available fields for your products grids, click on the in the 'Add a field' panel and enter the following information:
What is the field ID?: myfeature
Sc creates the field, you now need to populate the grid with:
Field name: Feature
Table: Another table
Type: only display
From the Advanced Properties panel on the right handside:
- select the menu SQL Select and enter:
return ', (SELECT GROUP_CONCAT(fvl.value) FROM '._DB_PREFIX_.'feature_product fp RIGHT JOIN '._DB_PREFIX_.'feature_value_lang fvl ON (fvl.id_feature_value = fp.id_feature_value AND fvl.id_lang = '.(int)$id_lang.') WHERE fp.id_product = od.product_id AND fp.id_feature = 2) AS myfeature';
In this example, we use the feature group ID 2: adapt to your needs.
Exit the editing window.
The new field is now present in the list of available fields and you can add it to your Order grids.
