How to locate where custom code is written?

[Sairon]

Hello,

I have an old Prestashop store where one part of the store was custom coded, and now I would like to copy all the responsible code to a new shop, but I can't find where it is located. 

Store URL from which I would like to take the code: https://www.kariskizetonai.lt/home/8-karisku-zetonu-komplektas-juodas.html

In the photo below there is the section with the features I would like to copy and paste to my new shop, and also, how it looks in the BO:

 

This feature allows to limit the available characters and the number of them. It also displays how it will look in real time, and you can chose the which image is prescribed for which product, so if you pick a different product, the colour changes. 

 

Also how many and which files are responsible for the mentioned actions (How many files are there)?

Be carefull and do not just overwrite some files.

1rst step is a back up. Files and database.
2nd step is seeing if the old code is up for it. Php has changed a lot over the last 7 years.

Try to get your shop working locally (localhost) and work from there.

If the custom code is a module, then it would be in projectroot/modules folder obviously. Also, check override folder

When it is not a module, my safe bet would be to make sure the same PHP version (as pointed out) and PrestaShop version

It looks like it is module rw_customizatorius

@endriu107 Thanks, I have found it in the public_HTML folder. Is it possible to extract it from there so I have the files on my desktop?

[Sairon]

Thank you @s4lvozesta for your reply. How can I check if the files will be supported by a newer PHP version?

Update: 

I have downloaded the module, but it is showing up correctly in the BO or FO. Does any one know how to fix it? Attaching images below how it looks on the old version, and new:

Until PrestaShop 1.7 there is new way to display modules in product edit page, modules not having this option will not work. I think you should contact with this module developer or you should use other module.

Using another module is not an option, since the code was written specifically for us for the reason. Is it difficult and hard to edit the code in order to make it work? Do you @endriu107 maybe have the knowledge to do these changes?
