Are the weather "stickers" such as in wxgraphics (Anole) automatically updated should another visitor place one on their website or does it require a page refresh?

Thanks!

Anole's graphic is a PHP script, and, in normal usage, is constructed new every time it's called by a page. However, the data is only as new as the upload time of the data file the script is using.

Thank you for the clarification.  So there is no real way for the image to be refreshed "automatically" unless a user does a page refresh?

That's a question better left to more skilled programmers than I am. I wonder if an Ajax sticker could be created, and how it would muck up a page with other AJAX on it.

Add a little JavaScript, and an image can be refreshed automatically without reloading the page.  I use this simple script for my webcam thumbnail (uploaded every 15 seconds) to keep it refreshed on my webpage.   You could replace the <img src="...jpg" .. /> with the url for the weather graphic PHP script and it would work just the same.

Code: [Select]

    <p>Get a <a href="sticker.php">weather graphic.</a></p>
    <a href="netcam.php"><img src="netcam-thumb.jpg" id="myPull" alt="Netcam facing North-East" width="120" height="90" /></a>
    <p>See <a href="netcam.php">live netcam</a>.</p>
<noscript><p style="color:#FF0000"><b>Note:</b> enable JavaScript to see updated image and live weather updates.</p></noscript>
<script type="text/javascript"><!--
//<![CDATA[
function reloadImage() {
    var now = new Date();
    if (document.images) {
        document.images.myPull.src = 'netcam-thumb.jpg?' + now.getTime();
    }
    setTimeout('reloadImage()',15000);
}

setTimeout('reloadImage()',15000);
//]]>
-->
</script>

The JavaScript appends a '?timestamp' to the URL to make sure the browser doesn't cache the image.

Hope this helps...
