Hello,
I am a newbe at php.
I am building a form that needs to go back to the database and get a value when a user fills
in a slef.


Here is what I have so far



PHP Code:
<?
$today
=date('m/d/Y');
?>
<html>
 <head>
  <title>Test</title>
  <script language="javascript" src="pofunctions.js"></script>
  <link rel="stylesheet" type="text/css" href="standard.css">
<script language='javascript'>
<!--


function lookupStoreAddress(formname)
{
if (str=="")
  {
  document.getElementById("test").innerHTML="";
  return;
  }
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("test").innerHTML=xmlhttp.responseText;
    }
  }

xmlhttp.open("GET","getStoreAddress.php?store="+str,true);
xmlhttp.send();

}

  
-->
</script>

</head>
<body


<input class='inputField' type='text' name='store' onblur="lookupStoreAddress(this)">
<input class='inputField' type='text' name='addressStreet' readonly="readonly"  size='40'  >
<input class='inputField' type='text' name='city' readonly="readonly"  size='40'  >
<input class='inputField' type='text' name='state' readonly="readonly"  size='40'  >


</body>
</html>

I have built a php file, getStoreAddress.php

Based on w3schools
http://www.w3schools.com/php/php_ajax_database.asp

Which takes in:


PHP Code:
<?php
$store
=$_GET["store"];
...


...

mysql_close($con);
?>

What is the easest/best way to return the values (address, city, state) from getStoreAddress.php
and get them on the main form.

also,
I am not sure what to do with the "test" in lookupStoreAddress


thanks
