Here is a fully functional File Upload Handler function. You simply pass it the name that you typed
on the form, the upload dir (and others if your advanced,) and viola!
call like so:
$OkExt = Array('php', 'htm', 'html')
DoFileUpload('Userfile', 1024, './upload', '', $OkExt , '',
'')
$ForceFilename is if you want to use this name instead of whats in the $_FILES var.
$Overwriteok - set to anything but '' for yes
$ErrorFunction - set to the name of a function you defined, or '' to use default.
Need help? ask again.
Not that you may have to fix word wrap...
