Question

I’m trying to place markers on a google map based on values filed in a mysql db. When loading the xml dynamically using PHP, no markers get placed on the map due to the responseXML.DocumentElement property not getting valued. It works when I load the XML from a static file, just not when dynamically loading from a db.

Here is the page that doesn’t work: http://www.thirstygolfer.com/utils/maptest2.html
Here is the page that works: http://www.thirstygolfer.com/utils/maptest1.html

This is the PHP file generating the xml: http://www.thirstygolfer.com/utils/xmldump3.php

Here is the PHP code from thirstygolfer.com/utils/xmldump3.php (minus the db connection info):

<?php

$dom = new DOMDocument("1.0");
$node = $dom->createElement("markers");
$parnode = $dom->appendChild($node); 

$result=mysql_query("SELECT * FROM Main WHERE State='MA' and FirstLetter='A'");

header("Content-type: text/xml");

while ($row = mysql_fetch_assoc($result)){    

$node = $dom->createElement("marker");   
$newnode = $parnode->appendChild($node);     
$newnode->setAttribute("id",$row['id']);  
$newnode->setAttribute("lat", $row['Lat']);    
$newnode->setAttribute("lng", $row['Lon']);    
} 

echo $dom->saveXML();

?>

Please help!!

Answer 1

The headers on the XML are not correct (from web-sniffer.net)

HTTP Response Header

The Content-Type needs to be “text/xml”
