Disable the EAN control function

[alextn]

Hi everyone, Prestashop 1.7. I need to modify for reasons I am not explaining the isEan13 function so that in the EAN 13 field letters and numbers can be entered without any control. I opened the classes / validate / validate.php file and modified the isEan13 function like this:

    public static function isEan13 ($ ean13)
    {
      return is_string ($ ean13);
    }

Entering numbers all ok, entering text letters, I always get the error This value is not valid. Any help please?  PS 
cash emptied

mass capital letters on title removed (see edit history)

I was wrong! I meant I emptied the cache. Can you help me?

From the top of my head:

 - this function is called from a table in the Validate.php Class file.

 - That table also contains a field that this is numeric

Yess. Tnks...

Solution:

//////////////////////////////////////////////////////////////////////

make the following changes

FILE: classes/Validate.php

public static function isEan13($ean13)
{
return !$ean13 || preg_match('/^[0-9]{0,13}$/', $ean13);
}

it becomes

public static function isEan13($ean13)
{
return !$ean13 || preg_match('/^[a-zA-Z0-9]{0,13}$/', $ean13);
}

//////////////////////////////////////////////////////////////////////

FILE: src\PrestaShopBundle\Form\Admin\Product/ProductOptions.php

  ->add('ean13', FormType\TextType::class, [
                'required' => false,
                'error_bubbling' => true,
                'label' => $this->translator->trans('EAN-13 or JAN barcode', [], 'Admin.Catalog.Feature'),
                'constraints' => [
                    new Assert\Regex('/^[0-9]{0,13}$/'),
                ],
                'empty_data' => '',
            ])

 

it becomes

  ->add('ean13', FormType\TextType::class, [
                'required' => false,
                'error_bubbling' => true,
                'label' => $this->translator->trans('EAN-13 or JAN barcode', [], 'Admin.Catalog.Feature'),
                'constraints' => [
                    new Assert\Regex('/^[a-zA-Z0-9]{0,13}$/'),
                ],
                'empty_data' => '',
            ])

Hello, 

my problem is, i need 14 numbers. If i change the Value 13 to 14, dont work. 

[alextn]

 

Where are you doing the tests? on the product or on one of the product combinations?

[Birnex]

What for a test? I change the part:

 

Assert\Regex('/^[a-zA-Z0-9]{0,13}$/'),

NEW

Assert\Regex('/^[a-zA-Z0-9]{0,14}$/'),

 

the Page works. But i cant open the Admin page. 

[alextn]

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

 

 

replace the attached files with the original ones in the respective prestashop positions - version 1.7 only. Clear the cache, and try again.

ProductCombination.php

ProductOptions.php

Validate.php

[Birnex]

I do the change only in ProductOptions and Validate.php.

 

ok i try it

[Birnex]

I do the change only in ProductOptions and Validate.php.

 

ok i try it

[Birnex]

I check the files. There is no change in the  EAN 13. i need 14 numbers. 

[alextn]

 

change the number 13 with 14 on the function, on all 3 files I have attached to it.

 

Clear the cache, and try again.

 

must work. be very careful the cache

[musicmaster]

Don't forget to adapt the fieldsize in the database

[Birnex]

Where ist the cache file? And wich structure in the database i must change?
