Multiple file delete

I have a page that displays the contents of a folder. Right now, each file has a little 'delete' button next to it that users can click on, however with many files it gets cumbersome. I need to be able to have them click on checkboxes and then hit one delete button which will then get rid of everything checked, but I don't know how to combine the form with PHP so that it takes the info from one into the other and delete what's needed. Any pointers would be very helpful. Thanks. -- A
