Inserting Mysql Info

[dombrorj]

I have a form and a database put together. The form is an opt-in list to join my newsletter. The form calls a php file, which sends the visitor who submits his/her name and email a welcome message. What I need to do is make the php file also insert the submitted information to my database. So when the visitor types their name and email in the form, and clicks "submit," it sends the info to my database. How would I go about doing this? Thanks in advance!
