progress bar while code executes?

Anon

anyone seen anything like that? i have a script that calls text from a really slow server (.gov) and was hope to give a ticker while folks waited.

i could write a time counter script but it wouldn't output text until done. i don't know enough javascript to have php work in an image loader progress bar.

any ideas?

thanks,
nm

Hi Nick,

If you put your PHP after the <HEAD> tag in HTML, then you should be able to use a onload() event handler in the <BODY> tag to give some sort of time difference.

For example:

<HEAD>
<SCRIPT TYPE="text/javascript">
var now = 0;
var counter = setInterval('update()',1000);
function update() {
now++;
document.form.element.value = now;
}
</SCRIPT>
</HEAD>
<BODY>
<FORM>
<INPUT TYPE="XXX">
</FORM>
<?PHP GOES HERE ?>
</BODY>

If you know exactly how long the query will take, then it shouldn't be a problem to use this functionally.

You could also write something that says the page is loading in the status bar or something, or even on the page itself if you fancy implementing the DOM!

Kind Regards,

David

Dave's suggestion will certainly work, but all it really does is replace the browser's "busy" indicator with a javascript one--if the php page is hung in an endless loop, it won't be any the wiser. If that's good enough for you, no problem. Otherwise, writing plain text (especially not inside any TABLE or SPAN elements, followed by a <br> and one or more flushes(), might get the content out depending on the browser. Then, when you're done, flush that be writing </html> and open a new html section for your real page content.
