-- HikaShop version -- : 4.2
-- Joomla version -- : 3.4

I have a custom field in the item table (text field) assigned to a product. Customers can enter an existing serial number on the product page. I would like to check that the serial number is valid, via a database query, before the product is added to the cart, or display an error if invalid. Can you advise suitable approach? Thanks

From what I have seen, the only validation that you can currently do is whether it is required or not. I earlier recommended that they add in the ability to do a Regex validation on a custom filed. To do a database validation would be more involved, but you could request that feature be added.

I have customers that need to supply a serial number in order to purchase a software upgrade. I made a custom field for the applicable products and made it required, but the customer can enter whatever they want. We have to validate that serial number when we get the order. If they do add that feature, I would be interested in it. If they at least added a Regex validation, the customers couldn't just enter any old value.

Hi,

A regex validation for the custom fields has already been added to the latest version of HikaShop.
But if you want to validate against a database of valid values, as gpraceman said, it will require something more involved.
HikaShop has a lot of triggers which are listed on our developer documentation:
www.hikashop.com/support/support/documen...r-documentation.html
There, you'll find the triggers for the custom fields.
They allow you to create new types of custom fields via the development of a HikaShop plugin.
So you could create a new type of custom field, basing it on the standard text field type and overriding the check function to do your own check the way you want.
If you want a complete example, you can look at the advanced date picker plugin which is available in the folder plugins/hikashop/datepickerfield of your website.

Two weeks ago, you indicated that you would look at adding such a feature. If that feature has already been added, where is it available? When I edit a custom field, I don't see any Regex option.

Nicolas thanks, creating a new custom field looks the way forward. I will have a look through the Datepickerfield example. It would be nice if there were some comments in these code suggestions.

gpraceman, it seems we are tying to solve the same requirement.

That's right. Two weeks ago as said that we would look into it, and we did.
We released the latest version yesterday and you can see that new feature mentioned on the change log of that new version:
