[PS.1.7] Extend Product Page (BackOffice)

[andrekat]

Hello everybody!

I'm relatively new to the PrestaShop world, but I've come quite a long way in this short time. My goal is to display an extra field on the product page as an HTML field (multilingual). This already works well. I add this using hook:

"hookDisplayAdminProductsMainStepLeftColumnMiddle"

... I have also added the desired field to the product_lang table.
My problem: the field is not stored in the database. Should this be serialized automatically if the field in the Product.php (Class) has been extended, or do I have to map my own logic here?

Unfortunately I'm not getting any further & that's why I'm trying my luck here!

Thank you in advance,

Andre
