Hi,
I'm learning Google Maps and WordPress plugins. I've built a basic Google
Maps shortcode plugin. But, I'm having problems placing markers on the map.
The map is visible and I've pulled the lat long coordinates from a MySQL
database. I'm following the
tutorial<http://code.google.com/apis/maps/articles/phpsqlajax_v3.html>here.
I'm not sure how to output XML from a WordPress plugin. This a snippet from
my plugin:
$dom = new DOMDocument('1.0');
$node = $dom->createElement('markers');
$parnode = $dom->appendChild($node);
$csf_data = $wpdb->get_results($wpdb->prepare("SELECT * "));
foreach($csf_data as $incident) {
$node = $dom->createElement('marker');
$newnode = $parnode->appendChild($node);
$newnode->setAttribute("lat", $incident->latitude);
$newnode->setAttribute("lng", $incident->longitude);
}
die();
echo $dom->saveXML;
In the tutorial, the php script is in a separate file and when it runs, it
outputs XML. In my case, the code above is in the main plugin file. Also, in
the tutorial this: function downloadUrl(url, callback) is used to load the
XML file. How do I output the XML to a separate file in WordPress, so that I
can use this function?
How do I tell if XML has been output by WordPress?
How do I export the XML to a separate file in WordPress?
How do I load the XML file in WordPress?
Any suggestions? Thank you.
