javascript var to a remote php script...

Anon

How can I send from a javascript, vars that I can use, and then send back say an image? I want to set up a mini-counter service for my clients and need the js to embed in an html page but can process and return the count via php. Any ideas?

Thanks.

Marcel.

you can do it all in php

In this case, the function sendVars() would send a PHP var via the URL. You'd have to GET the var in a form previous to coming to this action page.

The function getImg() would get a specific image, for example:
$hour = date("g");
if ($hour > 9) {
$hour = ($hour - 10) }
returns the current hour, so <img src="http://www.url.com/numberpics/<?=$hour.jpg?>> would return 6.jpg from that site.

function sendVars()
{
location.href=http://www.url.com/index.php?var=<?=$value=?>;
}

function getImg()
{
document.write "<img src=\"http://www.url.com/numberpics/<?=var?>.gif>";
}

</script>

Of course, it would return 6 at 6:00 only! It would return a 2 at 12:00, so you have to build into the function that if $hour > 10 you also pull a 1.jpg image. You get the idea...
