PrestaShop Module Development

Updating the module code

Updating the MySQL table is good, but, for the moment, our module does not use this new field.

Updating the ObjectModel class

Since we use an ObjectModel class to insert comments and retrieve it, we will add the id_shop field in this class.

In your classes/MyModComment.php file, add the shop ID just below the comment ID:

public $id_shop;

Then, add it in the fields list of the $definitions array:

'id_shop' => array('type' => self::TYPE_INT, 'validate' =>
'isUnsignedId', 'required' => true),
