Hi! I have just read 'Save File with Ajax and PHP' on http://techslides.com/save-file-with-ajax-and-php and I found it very useful. I tested and it works. However, I notice that there are two major limitations:

The first is that files are only saved on server in .txt form, not in .html or .php.
And the second is that files, even in .txt form, are impossible to be saved on a different folder, even if you change the $dir in both files (index.html and save.php).

Also, I was wondering if there is a way to name the file.txt directly rather than make it on the server.
