Prestashop1.7 : Remove Lastname Field Rules Validation From B.O

[wajdikick]

I am trying to remove rules validation for customer's Lastname field..

I have succeed to do it in the front page for customer registration by editing Classes/Customer.php file like this:

'lastname' =>array('type' => self::TYPE_STRING, 'validate' => 'isCustomerName', 'required' => true, 'size' => 32),

to :

'lastname' =>array('type' => self::TYPE_STRING, 'validate' => 'isAnything', 'required' => true, 'size' => 32),

I have simply used isAnything in validation.

But that's not working in the Backoffice, so i can't edit customers from BO.

Can't find what file to change exactly.

I am using Prestashop V1.7.6.8.

Need help please. Thanks
