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 <? $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> PHP: I have built a php file, getStoreAddress.php Based on w3schools http://www.w3schools.com/php/php_ajax_database.asp Which takes in: <?php $store=$_GET["store"]; ... ... mysql_close($con); ?> PHP: 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
