Erstellen Zeitstempel KML von PHP

Question

Ich versuche, einen Punkt KML mit Zeitstempel zu machen. Die MySQL-Ausgabe sieht wie folgt aus:

KML_time,coordinates 
2012-3-26T04:36:39-01:00,"9.92016904,57.04809917,0" 
2012-3-26T04:36:54-01:00,"9.92017704,57.04809437,0" 
2012-3-26T04:37:08-01:00,"9.92011376,57.04819547,0" 

ich andere PHP-Skript gemacht haben KML zu schaffen, die funktioniert prima, aber aus irgendeinem Grund dieses hält nichts zu tun. Der PHP-Code sieht so aus:

<?php 
require('../db_conf2.php'); 

// Opens a connection to a MySQL server 
$connection = mysql_connect ($server, $username, $password); 

if (!$connection) 
{ 
    die('Not connected : ' . mysql_error()); 
} 

// Set the active MySQL database 
$db_selected = mysql_select_db($database, $connection); 

if (!$db_selected) 
{ 
    die ('Can\'t use db : ' . mysql_error()); 
} 

// Select all the rows in the markers table 

$query_trips = "SELECT KML_time, GROUP_CONCAT(lon, ',', lat, ',', '0' ORDER BY ts DESC SEPARATOR ' ') AS coordinates FROM demo_timespan GROUP BY id"; 

$result_trips = mysql_query($query_trips); 
if (!$result_trips) 
{ 
    die('Invalid query: ' . mysql_error()); 
} 

// Start KML file, create parent node 
$dom = new DOMDocument('1.0','UTF-8'); 

//Create the root KML element 
$node = $dom->createElementNS('http://www.opengis.net/kml/2.2','kml'); 
$dom->appendChild($node); 

//Create a Document element and append it to the KML element 
$documentNode = $dom->createElement('Document'); 
$node->appendChild($documentNode); 

//Create a hiker icon Style element and append it to the Document 
$styleNode = $dom->createElement('Style'); 
$documentNode->appendChild($styleNode); 
$styleNode->setAttribute('id','hiker-icon'); 

$iconStyleNode = $dom->createElement('IconStyle'); 
$styleNode->appendChild($iconStyleNode); 

$iconNode = $dom->createElement('Icon'); 
$iconStyleNode->appendChild($iconNode); 
$hrefNode = $dom->createElement('href', 'http://maps.google.com/mapfiles/ms/icons/hiker.png'); 
$iconNode->appendChild($hrefNode); 

//Create a check-hide-children Style element and append it to the KML element 
$styleNode = $dom->createElement('Style'); 
$documentNode->appendChild($styleNode); 
$styleNode->setAttribute('id','check-hide-children'); 

$ListStyleNode = $dom->createElement('ListStyle'); 
$styleNode->appendChild($ListStyleNode); 

$listItemTypeNode = $dom->createElement('listItemType', 'checkHideChildren'); 
$ListStyleNode->appendChild($listItemTypeNode); 


//Create a check-hide-children URL element and append it to the KML element 
$styleUrlNode = $dom->createElement('styleUrl', '#check-hide-children'); 
$documentNode->appendChild($styleUrlNode); 


//Iterate through the MySQL results 
while ($row_trip = mysql_fetch_assoc($result_trips)) 
{ 

//Create a Placemark and append it to the document 
$placenode = $dom->createElement('Placemark'); 
$documentNode->appendChild($placenode); 

//Create a Timestamp and append it to the PlaceMark 
$Timestampnode = $dom->createElement('Timestamp'); 
$placeNode->appendChild($Timestampnode); 

//Create a When and append it to the Timestamp 
$whenNode = $dom->createElement('when',$row_trip['KML_time']); 
$Timestampnode->appendChild($whenNode); 

//Create a StyleUrl and append it to the PlaceMark 
$styleURLNode= $dom->createElement('styleUrl', '#hiker-icon'); 
$placeNode->appendChild($styleURLNode); 

//Create a Point element 
$PointNode = $dom->createElement('Point'); 
$placeNode->appendChild($PointNode); 
//Create a coordinates element and give it the value of the lng and lat columns from the results 
$coorNode = $dom->createElement('coordinates',$row_trip['coordinates']); 
$PointNode->appendChild($coorNode); 

} 
$dom->saveXML(); 

//assign the KML headers. 
header('Content-type: application/vnd.google-earth.kml+xml'); 

$dom->save("../store_kml/Timespan.kml"); 
?> 

Bitte helfen, bevor dies mich zum Wahnsinnigen macht!

Dies ist das PHP-Skript, das ich verwende, um Polylinien zu machen, und es funktioniert gut. So kann ich nicht wirklich sehen, warum die anderen nicht funktionieren.

Answer 1

$query_trips = "SELECT KML_time, GROUP_CONCAT(lon, ',', lat, ',', '0' ORDER BY ts DESC SEPARATOR ' ') AS coordinates FROM demo_timespan GROUP BY id"; 

Wahrscheinlich das, wo in es sein sollte ..

$query_trips = "SELECT KML_time, GROUP_CONCAT(lon, ',', lat, ',', '0' ORDER BY ts DESC SEPARATOR ' ') AS coordinates FROM demo_timespan WHERE lat>50 AND lon>8 GROUP BY id"; 

oder dies nur

$query_trips = "SELECT KML_time, GROUP_CONCAT(coordinates) AS coordinates FROM demo_timespan ORDER BY id"; 

Leider habe ich falsch verstanden, was du versuchen, mit CONCAT zu erreichen Koordinaten cooooooompletely etwas anderes . Müde. Also, da andere Abfrage es tut, rate WHERE lat> 50 AND lon> 8 fehlt. Alles sieht gut aus.

Answer 2

Ich denke nicht, dass Sie den Zeitstempel richtig erstellen. Zunächst wird die korrekte Syntax ist Timestamp (nicht Zeitstempel) und man könnte es in einem TimePrimitive wickeln müssen

so sollte Code aussehen

 $Timestampnode = $dom->createElement('TimeStamp'); 

und haben vielleicht eine

 $TimePrimitivenode = $dom->createElement('TimePrimitive'); 

die enthält den TimeStamp

Edit: Sieht aus wie Sie Timestamp auch falsch sein könnte. Wenn man Sekunden einbezieht, muss man entweder ein 'Z' am Ende anhängen, um UTC anzuzeigen, oder man muss etwas wie '+03: 00' hinzufügen, um anzuzeigen, wie die Zeit in UTC umgerechnet wird. link
