printf Posted October 16, 2006 Share Posted October 16, 2006 This looks like a zip class I wrote years ago (late 99), anyway this class will have problems some dates which will corrupt the zip file! You are better off get a newer version!the class function add_dir(), does not add the contains of a directory, it just creates a zip compatible directory, where files added to it will be placed into that structured directory! You need to use glob() in a foreach() loop adding the files as you loop the add_file() class function!I'll give you a download attachment example in a few minutes!me!
