This is the index.php
"<form action="javascript:read()" method="post">
<input type="submit" name="Submit" value="read"/>
<input name="id" type="hidden" id="id" value="<? echo $userid; ?>"/>
</form>"

This is ajax

"function createObject() {
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}

var http = createObject();
var nocache = 0;

function read() {

document.getElementById('insert_response').innerHTML = "Just a second..."

var id = encodeURI(document.getElementById('id').value);

nocache = Math.random();

http.open('get', 'read.php?nocache='+nocache+'&id='+id);
http.onreadystatechange = insertReply;
http.send(null);
}
function insertReply() {
if(http.readyState == 4){
var response = http.responseText;

document.getElementById('insert_response').innerHTML = 'Site added:'+response;
}
}"

And this is the read.php
"
