title: How to make Email Button that populates an address from database?
body: <p>I'm working on a site a bit like craigslist only very small scale.  I need help making a button that a user could click to email a seller of a particular item.  I need to populate the email with the seller's email address which is stored in a database.  This may be simple but I'm really new to php and not sure how to begin.  Could anyone help me with the code?  Very grateful for any help! </p>
