Adding required field checking in Product Insert

Hello Jason,

I want to add required field in product_insert.php which is at "SKU/Product" Id field in the form.

Can you show me detail php coding example to do that?
And is there any tutorial related to do validation used in Power 4.5?

Thanks so much, looking forward to hear from you soon.

we do not offer support for customizing the functionality of power store.

if you would like help with customizing power store functionality, i would suggest signing up for a premiere ticket where we would work with you in a one on one session through screen sharing.

I thought field validation toward one of Power Store fields is kind of explanation or tutorial to me because there already two fields being treated like that i.e. "product name field" and "price field" are required to be filled field.
And I tried to look for explanation in power store 4.5 documentation about validating field but so far could not find.

I have bought from Web Assist CSS Form Builders and Validation Tool kit 2.0 which I think have relation with Power Store 4.5 validation.

If you can give me a hint, or there is related tutorial about it, I like to learn myself first, before asking for premium support.

Thank.
