Lookup based on data entered

I don't supposed there's a way to have a field that can lookup data from a table and fill in the remaining fields based on that record in the table? In other words, the field would lookup data in a MySQL database and populate the remaining fields in the form. Example: Enter a customer's number and it populates the name and full address.

Unfortunately no, not through the form builder. It would however be possible if you use the source code of your form and then hire a developer to implement this specific feature for your form.

It would require ajax calls to be made to your database to be able to pull it out based on the user entered details, but as mentioned, it requires implementation within the source code with which we can not assist, but a developer would need to be hired instead.
