How can I create a .txt or write to a .txt file in javascript? The .txt file will be on my site and I just need it to be able to be written to.
Thanks.

Creating or writing to a file in javascript.
You can't.
Use php or some other server side language for that...

Is there any way to send a variable to a php script then?

yep its very easy
add the variable to the end of the url and "get" it using php (example follows)
url: www.mypage.com/index.php?name=bob
php code to "get" it:
| Code: |
| <?php
if (isset($_GET['name'] { //check whether "name" is set to anything $name = $_GET['name']; //store it in "$name" } ?> |
then read http://dk.php.net/manual/en/function.fwrite.php which is about the php file module...
(if you cant figure it tell me exactly what you want and i will program it...)
Sorry I meant is there any way to send a variable from the javascript to a php script.

Yes, and that was what i answered!
Either you "call" a new page with document.location and use the $_GET stuff i showed above, or you could give AJAX a try (if you dont want the page to refresh) - however learning AJAX is something that many people can explain way better than me - so search google for it
That involves you having to post the data though. Is there any way to do it all on page load.
You load the page and the file is written to.

eh...well...yea...what kinda thing are you trying to write?
(it sounds like a VERY SIMPLE task using php...)
You cannot directly write into a .txt (or any other file) from javascript but you can always do it by using JavaScript in combination with Java Applets.
I was able to succesfully read the data in a file into JavaScript in one of my assignments.The process goes this way:
- Create an applet with public methods that can make a URL connection to the file (because u cant open the file directly) and do the required editing for you.
- These public methods can be called from JavaScript to do the job for you.
- Though this makes a http connection , there is no post involved.

Hope this helps.

If you do do this, make sure to validate and security check the data SERVER SIDE or it will be very easy for hackers to insert malicious code into your file!

You must use FSO ( File System Object ) ActiveX in IE&Windows . if you use activeX in your page the browsers notify the user to confirm activeX runtime on the web page .
search google for FSO+Javascript for sampels .

No, thats not relevant, as he wants to write to a file on the server, not the client...anyway if he wanted to store the data locally, cookies would be a much better method...
