Hi
You could change your PHP file to return XML result centered on
Geolocation results using mysql_num_rows()
$result = mysql_query($query);
if (!$result) {
die("Invalid query: " . mysql_error());
}
header("Content-type: text/xml");
if (mysql_num_rows($result)==0)
$node = $dom->createElement("marker");
$newnode = $parnode->appendChild($node);
$newnode->setAttribute("name", "No Records Found");
$newnode->setAttribute("address","Centered on Location);
$newnode->setAttribute("lat", $row['lat']);
$newnode->setAttribute("lng", $row['lng']);
$newnode->setAttribute("distance",0);
else {
// Iterate through the rows, adding XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
$node = $dom->createElement("marker");
$newnode = $parnode->appendChild($node);
$newnode->setAttribute("name", $row['name']);
$newnode->setAttribute("address", $row['address']);
$newnode->setAttribute("lat", $center_lat);
$newnode->setAttribute("lng", $center_lng);
$newnode->setAttribute("distance", $row['distance']);
}
}
I have not tried this out yet
