upload

问题 I'm doing multiple file uploader to upload my files by using XMLHttp 2. When i'm doing this, if i upload the files one by one (by sending a file through an ajax request and waiting it to complete before sending the next and so on), the uploader works well.

问题 I have a form which the user fills with lyrics information and uploads an album cover. Submitted data will be inserted into a database and the album cover will be moved to a subfolder. localhost/project-folder/covers I've taken some precautions (escaping, prepated statements) against SQL Injection for the form input.
