Hi, I'm trying to make a website with Google Maps API and get coords from MySQL db. So far so good, but only in Chrome or Safari. Markers won't show in Internet Explorer. I could use some help. I followed this guide from Google https://developers.google.com/maps/articles/phpsqlajax_v3 Anyway, here's my code. Any help would be appreciated, thanks.
var customIcons = {
sport: {
icon: 'images/markers/sport.png',
},
bar: {
icon: 'images/markers/bar.png',
},
poi: {
icon: 'images/markers/poi.png',
},
skola: {
icon: 'images/markers/skola.png',
},
kino: {
icon: 'images/markers/kino.png',
},
divadlo: {
icon: 'images/markers/divadlo.png',
}
};
function nactimapu() {
var map = new google.maps.Map(document.getElementById("mapa"), {
center: new google.maps.LatLng(49.068299, 17.460907),
zoom: 15,
mapTypeId: 'hybrid'
});
var infoWindow = new google.maps.InfoWindow;
// Change this depending on the name of your PHP file
downloadUrl("querymapa.php", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var nazev = markers[i].getAttribute("nazev");
var popis = markers[i].getAttribute("popis");
var typ = markers[i].getAttribute("typ");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var html = "<b>" + nazev + "</b> <br/>" + popis;
var icon = customIcons[typ] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
animation: google.maps.Animation.DROP,
icon: icon.icon
});
bindInfoWindow(marker, map, infoWindow, html);
}
});
}
function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
infoWindow.open(map, marker);
});
}
function downloadUrl(url, callback) {
var request = window.ActiveXObject ?
new ActiveXObject('Microsoft.XMLHTTP') :
new XMLHttpRequest;
request.onreadystatechange = function() {
if (request.readyState == 4) {
request.onreadystatechange = doNothing;
callback(request, request.status);
}
};
request.open('GET', url, true);
request.send(null);
}
function doNothing() {}
Here is xml output in php, maybe there is a mistake. Sorry that I didn't post it earlier.
<?php
require("dbconfig.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','<',$htmlStr);
$xmlStr=str_replace('>','>',$xmlStr);
$xmlStr=str_replace('"','"',$xmlStr);
$xmlStr=str_replace("'",''',$xmlStr);
$xmlStr=str_replace("&",'&',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect ($dbserver, $dbuser, $dbheslo);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($dbname, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM lokace WHERE 1";
$result = mysql_query($query);
if (!$result) {
die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE
echo '<marker ';
echo 'nazev="' . parseToXML($row['nazev']) . '" ';
echo 'popis="' . parseToXML($row['popis']) . '" ';
echo 'lat="' . $row['lat'] . '" ';
echo 'lng="' . $row['lng'] . '" ';
echo 'typ="' . $row['typ'] . '" ';
echo '/>';
// End XML file
echo '</markers>';
?>
