query a field in database to fill a custom form

HI everyone i would love to be able to fill those custom form through the “candidate name”
any code available to do that, been searching since morning and couldn’t find any…
The “Next” and “previous” button is to navigate through the Data but the disadvantage is when when the data is much…

What do you want to do? do you have a database with all that data already init? then just link your elements to that database?

i have a similar form that fills and updates members profiles
