INSERT into mysql from html form

[JanMolendijk]

I wanna use this script but make a form field from it were i can add text into the forms INSERT INTO `users`,on:
https://coursesweb.net/php-mysql/php-mysql-insert

In that page there is an example script, in the section: "Insert data from a form into a database".
What did you try yourself, and where you can not make it work?

Thanks for the support i had to look better & found the way
