I don't think this is the "only possible way". I have used an html IMG tag,
then created something like a rollover effect that called a php file for the
image. It was kind of like a stop light, the light was off until focus came
off of a particular form element, javascript then updated the image href
with a few extra arguments, then the light turned green or red.
You can also use a javascript popup window to call a php script. I'm sure
there are a few ways to do this too.
Here's the javascript
<input type="text" size="45" name="1_1_email" value="" tabindex=1
onChange='validate_email()'><IMG SRC="./trans.gif" NAME=animation width=10
height=10 align=middle>
<SCRIPT>
function validate_email(){
document.animation.src = "./image.phtml?email=" +
document.forms[0].elements[1].value ;
return true;
}
</SCRIPT>
here's the php
<?php
include("get_connected.func");
// This script checks for the existence of an image file, and outputs it,
// if the image is not found than it will output a generic image
$yes_image = "./green.gif";
$no_image = "./red.gif";
header("Content-type: image/gif");
$mysqlconn = new MySQL_class;
$mysqlconn->Create($db);
$select = "SELECT COUNT(item_id) FROM mkt_question_response WHERE item_id =
'".$HTTP_GET_VARS["email"]."' GROUP BY item_id";
$mysqlconn->Query($select);
if($mysqlconn->rows > 0){
readfile($no_image);
}else{
readfile($yes_image);
}
?>

FAIK the only possibility is to redirect to the PHP script. Then
you'll get something like:
window.location.href="myscript.php";
