How to add a file upload function?

[chapt0r]

Here is my PHP code, I need to add a upload file function to this. I know how to add it to the Html side of things, but I am still fuzzy on the php side of things. Any ideas, hints, etc.




<?php
print("$name ");
print("Thank you submiting to x4a");
echo "<br>";
print("file upload is coming soon");

mail("$email", "Site Information", "Hello $name,\Thank you for submitting your work. \n\\n.");

mail("creations@covad.net", "x4a test", "$name Submitted their work.\n\nThere email is $email.");



?>


Thanks
Wes
