Extract email addresses when filling out Google Forms?

Question

PHP

Situation, a person receives an email with a request to fill out a questionnaire, follow the link to go to the Google form and fill it out.
How to make it so that when analyzing data, we had both an email and a variant of his answer. Needed in order to sort the email database into segments.

Answer 1

Check the box in the form settings "Only one response per person (login required)". At the same time, only Google account holders can fill out the form (mail.ru, yandex.ru, etc. will not work). In corporate Google App systems - this option is needed, even if it is worth checking that the form works within the corporate system. It's easier to insert a mandatory text field with data validation in which to enter email. But here is the catch, they will write something like: [email protected]
