HI premf5,
If you didn't set property "SaveDirectory". Please remove property setting "AllowedFileExtensions". Then you can upload all type of files (except the extension which willcause security risks, like asp/php/aspx)
For security reason, if you using property "SaveDirectory", you need to use property "AllowedFileExtensions" to set the extensions for uploader control. Like
$uploader->AllowedFileExtensions="*.jpg,*.png,*.gif,*.bmp,*.txt,*.zip,*.rar";
Regards,
Ken
