I have a page that needs to refresh one part every time the page is visited. This part is controlled by
include "refreshme.php";
However, the data only refreshes when the browser's refresh button is physically pressed. I have included the following headers at the top of the source page.
header("Expires: Thu, 1 Sep 2007 07:00:00 GMT");
header("Cache-Control: no-cache, must-revalidate");
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header("Pragma: no-cache");
Still no luck. Any idea on how to do this? I accomplish image refreshing by attaching a random number to the file. Example:
<?php $rand=rand(100000,999999); $rand="?".$rand;?>
<img src="<?php echo $picture.$rand;?>">
I cannot get something similar to work on the included php file.
Any help would be great. Thanks.
You could use some AJAX, here is how i would do it
1- in you head tag include this
<script type="text/javascript">
var page = "refreshme.php";
function ajax(url,target)
{
// native XMLHttpRequest object
document.getElementById(target).innerHTML = '<font color="white">0</font> some text here if needed';
if (window.XMLHttpRequest) {
req = new XMLHttpRequest();
req.onreadystatechange = function() {ajaxDone(target);};
req.open("GET", url, true);
req.send(null);
// IE/Windows ActiveX version
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = function() {ajaxDone(target);};
req.open("GET", url, true);
req.send();
}
}
setTimeout("ajax(page,'scriptoutput')", 10000); // the refresh time
}
function ajaxDone(target) {
// only if req is "loaded"
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200 || req.status == 304) {
results = req.responseText;
document.getElementById(target).innerHTML = results;
} else {
document.getElementById(target).innerHTML="ajax error:\n" +
req.statusText;
}
}
}
</script>
2- on your body tag call the function onload
ajax(page,'scriptoutput');
3- then include this div where you want the information displayed
<div class="regular" align="left"><span id="scriptoutput"></span></div>
This might need some changes to customize to your likes but it's a start.
im sure there are more ways to do this but this is one way, to refresh without actually refreshing the whole page.
Cheers.
