Hi, i would like to create a function as following
Warranty checking function:
1) admin able to create custom field and keyin data like name, address, invoice no, product, etc
2) user can use name + invoice number given from admin (as unique identifier), entering from front end website, will direct show all the details warranty information.
It is beyond the scope of support of Meta Box. It does not have any form to check the data on the frontend like that. If you want to create the custom code to do, please submit a service request here https://metabox.io/contact/, our developer will help you.
