Hello,

I have a problem with setting a cookie.
People can hide or show background but when they go to another page of the website this needs to be remembered so I need to save it in a cookie.
My code so far is

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>


<title>Menu toggle background</title>

    <style type="text/css">
    <!--
        * { margin: 0; padding: 0; }

        html, body { margin: 0; padding: 0; width: 100%; height: 100%; } 
        img { border: 0; } 

        img#back { 
            position: fixed; 
            left: 0px; 
            top: 0px; 
            width: 100%; 
            height: 100%; 
            z-index: -1; 
            _display:none;
        }   


        body {
            background-color: #94a5c3;
            font: 14px Century Gothic, Arial, Helvetica;
            color: #000080; /*#010271;*/
        }
        //-->
        </style>


<!-- SET COOKIE -->
<script type = "text/javascript">
// <body onload ="readCookie('mycookiename'); eraseCookie('mycookiename'); createCookie('mycookiename','anything', 365)">
//name = "mycookiename" or whatever name you wish to give the cookie
//value = "anything" - in this case the url of the image
//days = number of days cookie to remain active (say 365)

//Using the following functions are from quirksmode. - START
function createCookie(name, value, days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        var expires = "; expires=" + date.toGMTString();
    } else var expires = "";
    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') 
            c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) 
            return c.substring(nameEQ.length, c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name, "", -1);
}

function toggle() {
eraseCookie('background');
    var element = document.getElementById("back");
    var text = document.getElementById("displayText");
        if(element.style.display == "none") 
        {
            element.style.display = "block";
            text.innerHTML = "Hide Background";
            createCookie( "background", "id", 365);
        }
        else 
        {
        element.style.display = "none";
        text.innerHTML = "Show Background";
        createCookie( "background", "id", 365);
        }
} 
</script>    

</head>
<body onload ="readCookie('background'); eraseCookie('background'); createCookie('background','id', 365)">
<img id="back" src="http://miriadna.com/desctopwalls/images/max/Blue-sea-horizon.jpg" alt="" title="" /> 
<div style="border:0;position:fixed;top:300px;right:0;"> <a id="displayText" style="cursor: pointer;cursor: hand;" onClick="createCookie('background','id','365');toggle();">Hide Background</a></div>

</body>
</html>

I hope somebody can help me find a solution for my problem. (with javascript or php)
Thanks in advance.

Why don 't you use jquery it is easier and it has json that will talk to php easily
