Hello everyone!
What I would like to do is retrieve the contents of a PHP file and insert it into a div every 60 seconds, basically refreshing the
dynamic div. I've come up with the following
code so far, however it doesn't seem to be working. The
code is just like this, nothing extra, apart from the MYSQL login.
PHP to grab:
<?php
$time = date("m/d/Y h:i:s a", time());
mysql_query("UPDATE djs SET requesttime='{$time}' WHERE username='{$djs['username']}'")
or die(mysql_error());
$request_db = mysql_query("SELECT * FROM requests
WHERE haveplayed='0'") or die(mysql_error());
echo "<table style=\"border:1px solid;width:99%;margin-left:auto;margin-right:auto;\" border=\"1\">";
echo "<tr><th>Title</th><th>Artist</th><th>Dedicated To...</th></tr>";
while($request = mysql_fetch_array( $request_db )) {
echo "<tr><td style=\"width:33%;padding:1px;\">";
echo $request['SongName'];
echo "</td><td style=\"width:33%;\">";
echo $request['Artist'];
echo "</td><td style=\"width:33%;\">";
echo $request['DedicatedTo'];
echo "</td></tr>";
}
echo "</table>";
?>
The original PHP
code is just the same, enclosed in a div with an id attribute of 'ajax_table'.
The JavaScript is:
// JavaScript Document
var xmlHttp_moniter
function moniter()
{
xmlHttp_moniter = GetXmlHttpObject_parcel()
if(xmlHttp_moniter == null)
{
alert("browser does not support HTTP Request")
return
}
var url="ajax_table.php?random=" + Math.random()
xmlHttp_moniter.onreadystatechange = stateChanged
xmlHttp_moniter.open("GET",url,true)
xmlHttp_moniter.send(null)
}
function stateChanged()
{
if(xmlHttp_moniter.readyState==4 || xmlHttp_moniter.readyState == "complete")
{
document.getElementById("ajax_table").innerHTML = xmlHttp_moniter.responseText
setTimeout('ajax_table()',60000);
}
}
function GetXmlHttpObject_parcel()
{
var xmlHttp_moniter=null;
try
{
xmlHttp_moniter=new XMLHttpRequest();
}
catch (e)
{
//Internet Explorer
try
{
xmlHttp_moniter=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp_moniter=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp_moniter;
}
and that is on the page that is requesting the other php page.
