saving variable value and retrieve it after page refresh [duplicate]

Answer 1

Using javascript you can store that variable into a cookie (the user must have cookies enabled), and then retrieve the cookie after.

The approach is something like this:

To save:

function setCookie(c_name,value)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + 1);
var c_value=escape(value);
document.cookie=c_name + "=" + c_value;
}

To retrieve:

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i
