Passing Javascript Varaibles to Php

This is only for files under the same server or same website

Aim:To pass document.referrer variable to Php and to write the referrer variable on a text file;

First let us create two file called 1a.html and 2a.html

1a.html will contain a link to 2a.html

and 2a.html will contain just two javascript calls one will call a file called xml1.js

Files used 1a.html,2a.html,xml1.js,78.php and ip1.txt

Here is the source of 1a.html

Source of 2a.html

Here First we are calling xml.js javascript and then calling change1() function in it
Source of xml1.js

In the above function function GetXmlHttpObject() is nothing but creating Xmlhttpobject by which get function will be routed (AJAX).Do n’t worry about that if you need to more about there go to http://www.w3schools.com/ajax/ajax_source.asp.


Now let us go to the second line ,Here we are declaring change1 function and then we checking whether browser supports xml if not browser will display an error message indicating that “your Browser does n’t support AJAX”

Now let me explain what these four lines contain

The php file(78.php is like this

by this you can pass variables to a php script and from php you can insert any data into your database;



I hope this tutorial is helpful for others I have also written it in my blog

Remember this above one does n't uses location.href to redirect to a php page to pass varaibles like others

 

yes that's mine only
