I already have <div id="loadingNode"></div> in my HTML and both the HTML and PHP are in the same file and I want loadingnode to be populated with the message produced by PHP after user clicked appropriate link.

I think what you needs is Javascript code and not PHP

with php: As I said,

<div id="loadingNode"><?php print <content>?></div> Where <content> will be the result of the user clicking the

link in the html. But the link has to point back to server side php code. If you don't want the link to point back to server side php you do need javascript. But what you want to place in the div must already be in the page somewhere as a javascript string or hidden input field. You can also have the link initiate an async AJAX call to the server to get the div contents. And again that requires calling server side php. Php does not run in the browser. Only javascript (or in the case of Internet Explorer: VBscript: and in all you can use Flash ActionScript in an SWF file). These client side scripting approaches are separate subjects and require a good understanding of how to use them. JK

The way I would do this is to have some element in your html with an anchor tag with an href value set to your page LIke so <? $fileself = basename($_SERVER['PHP_SEF']) $div = "<div marup>"; if($_GET[do] == "changediv") { $div = "div markup changed"; } ?> <html> etc <body> <a href="<?php print $fileself; ?>?do=changediv">Change div</a> <?php print $div ?> </body> </html> In this case the user has to click the anchor, or there will have to be some more involved javascript processing involved, like an ajax request sent, but it still requires an action of the use to initiated.
