Hi
I am trying this code to display a google map with pointer and a info window to show the lat long.
when run in the server, it just shows a blank page and nothing else.
the var geo_json echoes null and this is why it is not going into if loop at all..
here is the code sample 1:
<?
$key = "ABQIAAAARhshcd0";
$address = urlencode("Birmingham West Midlands");
$url = "http://maps.google.com/maps/geo?q=".$address."&output=csv&key=".$key;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
$geo_json = json_decode($data, true);
var_dump($geo_json);
echo $geo_json;
if ($geo_json['Status']['code'] == '200')
{
$latitude = $geo_json['Placemark'][0]['Point']['coordinates'][0];
$longitude = $geo_json['Placemark'][0]['Point']['coordinates'][1];
?>
<iframe width="<?php echo $iframe_width; ?>" height="<?php echo $iframe_height; ?>" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="
[url]http://maps.google.com/maps?f=q[/url] &source=s_q&hl=en&geocode=&q=<?php echo $address; ?>
&aq=0
&ie=UTF8
&hq=
&hnear=<?php echo $address; ?>
&t=m
&ll=<?php echo $longitude; ?>,<?php echo $latitude; ?>
&z=12
&iwloc=
&output=embed"></iframe>
<?php
} else { echo "<p>No Address Available</p>";}
?>
I tried using this bit of code i got online from coffee site
