Disable isbn controller on combinations field

[masterwebsite]

good morning, I should be able to insert any value in the isbn field of the combinations. (now it only accepts numeric). Is it possible to know what I am missing? I have already modified the following files but I still have the error if I insert an alphanumeric value.
Thanks

src\PrestaShopBundle\Form\Admin\Product/ProductOptions.php
src\PrestaShopBundle\Form\Admin\Product/ProductCombination.php
classes/Validate.php

Hello,

 

To allow alphanumeric values in the ISBN field, you need to update the validation regex inside:

 

File Path:

https://github.com/PrestaShop/PrestaShop/blob/8.2.0/src/Core/Domain/Product/ValueObject/Isbn.php 

 

and update the VALID_PATTERN variable.

 

Change:

 

`[0-9]` or `[0-9X]` => `[0-9A-Z]`

 

If you want to allow different characters, you need to update the regex accordingly.

 

Thanks
