How to Add Custom Fields to Your Wix Contacts | No Code & Velo

Can you use the extended field to create custom fields for a store checkout page?

please can you start the javascript tutorials so will be easy for developers to use the code with wisdom

Thank you Eitan!
I wish your video would've come out a week ago. Glad I gave you further inspiration to create this video after all the troubles I had figuring this stuff out. So weird how Wix handles extendedfields in the JSON. I'm not really sure why they protect these fields and why you have to use their extended fields functions in order to access them rather than just the queryContacts functions. Actually, not sure why you just can't get to it using regular collection methods. I'm sure they have their reasons.
When I finish my code, I'll post it on the thread on your forum.
Thank you again for all the awesome videos! 🤓

First of all, love your work.
Im having terible experiences with Wix Contact. This CMS is such a pain, lacking of basic query function (like .contains), or unable to .find() by extenededfields. Really looking forward your Velo video on this.
Again, Thank you so much for your work
