Ciao a tutti,
ho un problema con il codice che allego sotto.
Praticamente in locale con PHP 5.2 funziona tutto bene,
in remoto (che è comunque una rete locale) con PHP 5.3 non c'è modo di farlo funzionare.
Dove sbaglio??
secondo me il problema è nel file findstate.php
Copio il codice:
File index.php
<html>
<head>
<title>Roshan's Triple Ajax dropdown code</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="javascript" type="text/javascript">

function getXMLHTTP() { //fuction to return the xml http object
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e1){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getState(countryId) {
var strURL="findState.php?country="+countryId;
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('statediv').innerHTML=req. responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
function getCity(countryId,stateId) {
var strURL="findCity.php?country="+countryId+"&state=" +stateId;
var req = getXMLHTTP();
}
</script>
</head>

<form method="post" action="" name="form1">

FILE findstate.php (secondo me quello che da problemi)
<? $country=intval($_GET['country']);
$link = mysql_connect('localhost', 'root', 'root'); //changet the configuration in required
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('test');
$query="SELECT id,statename FROM state WHERE countryid='$country'";
$result=mysql_query($query);
?>
<select name="state" onchange="getCity(<?=$country?>,this.value)">
<option>Select State</option>
<? while($row=mysql_fetch_array($result)) { ?>
<option value=<?=$row['id']?>><?=$row['statename']?></option>
<? } ?>
</select>
