asked on
pass a variable to my php page.
hello,
i totally don't understand the logic behind javascript. It's been the most frustrating thing to try to to discipher.
I have this bit of code and I need to pass a variable ($bookid) to the upload.php page. Sorry for the lengthy bit of code.

didn't work. I had tried that as well.

ok. upload.php:
name is echo'd but not bookid.
name is echo'd but not bookid.
<?php
echo $_GET['name'];
echo $_GET['bookid'];
?>
in your code, the only place you are passing the name variable is in the following function and it is going to index.php. you have to do a similar thing to pass the bookid to whereever you are passing the name variable.
you can call the function upload_complete with the extra var as shown below and it will get passed to the php page. same with wherever you pass vars to upload.php

{
window.location="index.php?name="+name+"&size="+size+"&type="+type+"&exts="+ft+"&bookid="+bkid;
}
I would probably activate / uncomment session_start to be sur that $_GET and $_POST do work as expected
<?php
session_start();
require_once("getid3/getid
<?php
session_start();
require_once("getid3/getid
What you need to do is attach your variable to the upload URL...
so: your upload url would need to be:
"upload.php?bookid=313"
(asuming that bookid is 313)
Then it would be in the GET data. and avaiable to your upload.php script.
obviuosly your javascript is making a request to your php script, much like you would if you were using a browser. the easiest way to pass on a variable whilst doing that is by attaching them after the url.. (this is a GET method) the other moethod is by POST, where you attach the information to the HTTP headers, which is a farmore complex task than is needed here.
