even though i hesitate to help someone who's excuse is meerely that they don't have time, i'll point you in the right direction. my time must not be as valuable as yours.
in short, there are 4 steps to this process.
1. add
enctype="multipart/form-data" to your form tag.
2. add a file field
<input type=file name=file>
3. after the form is submitted, use the
$_FILES[] array to get your data. The temporary file for this example would be
$_FILES['file']['tmp_name']
4.
copy the temporary file to a directory which allows the web user to write to.
All the elements are here, .. now you just need to put them together.
Good Luck!
