如何通過郵政編碼在谷歌地圖上繪製路徑

我想通過郵政編碼或城市名稱顯示路徑地圖和點之間的距離l ike我們輸入和來自地點和地圖將在它們之間生成，總之間的距離他們將被計算，請幫助它是緊急的。在此先感謝如何通過郵政編碼在谷歌地圖上繪製路徑

您可以分三步
1）生成郵寄城市或郵政編碼地圖
創建map1.php

<html> 
<head> 
<meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
<title>Google Maps JavaScript API v3 Example:Post City or Zip</title> 
    </head> 
<body > 
<form action="map2.php" method="post" > 
Enter 1st zip code/city <input type="text" name="input1" id="input1"><br/> 
Enter 2nd zip code/city <input type="text" name="input2" id="input2"> 
<input type="submit"> 
</form> 
</body> 
</html>

2）創建map2.php並生成地圖做到這一點

<!DOCTYPE html> 
<html> 
<head> 
<meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
<title>Google Maps JavaScript API v3 Example: Directions Simple</title> 
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" /> 

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script> 
<script type="text/javascript"> 
    var directionDisplay; 
    var directionsService = new google.maps.DirectionsService(); 
    var map; 

    function initialize() { 
    directionsDisplay = new google.maps.DirectionsRenderer(); 
    var chicago = new google.maps.LatLng(41.850033, -87.6500523); 
    var myOptions = { 
     zoom:7, 
     mapTypeId: google.maps.MapTypeId.ROADMAP, 
     center: chicago 
    } 
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 
    directionsDisplay.setMap(map); 
    } 

    function calcRoute() { 
    var start = '<?php echo $_POST['input1']; ?>'; 
    var end = '<?php echo $_POST['input2']; ?>'; 


    var request = { 
     origin:start, 
     destination:end, 
     travelMode: google.maps.DirectionsTravelMode.DRIVING 
    }; 
    directionsService.route(request, function(response, status) { 
     if (status == google.maps.DirectionsStatus.OK) { 
     directionsDisplay.setDirections(response); 
     } 
    }); 
    } 

</script> 
</head> 
<body onLoad="initialize(),calcRoute()"> 
    <?php 
    // calculate laglong by address and zip code 
    function getLatLong($address){ 
    if (!is_string($address))die("All Addresses must be passed as a string"); 
    $_url = sprintf('http://maps.google.com/maps?output=js&q=%s',rawurlencode($address)); 
    $_result = false; 
    if($_result = file_get_contents($_url)) { 
     if(strpos($_result,'errortips') > 1 || strpos($_result,'Did you mean:') !== false) return false; 
     preg_match('!center:\s*{lat:\s*(-?\d+\.\d+),lng:\s*(-?\d+\.\d+)}!U', $_result, $_match); 
     $_coords['lat'] = $_match[1]; 
     $_coords['long'] = $_match[2]; 
    } 
    return $_coords; 
} 
    $to = getLatLong($_POST['input1']);echo "<br/>";print_r($to); 
    $from = getLatLong($_POST['input2']);echo "<br/>";print_r($from); 
echo distance($to['lat'], $to['long'], $from['lat'], $from['long'], "m") . " miles"; 

// // calculate distance by lat long 
function distance($lat1, $lon1, $lat2, $lon2, $unit) { 
    $theta = $lon1 - $lon2; 
    $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)); 
    $dist = acos($dist); 
    $dist = rad2deg($dist); 
    $miles = $dist * 60 * 1.1515; 
    $unit = strtoupper($unit); 

    if ($unit == "K") { 
    return ($miles * 1.609344); 
    } else if ($unit == "N") { 
     return ($miles * 0.8684); 
    } else { 
     return $miles; 
     } 
} 
?> 


<div id="map_canvas" style="top:30px;"></div> 
</body> 
</html>

生成map和getLatLong（）函數查找laglong和距離函數查找城市或郵政編碼之間的距離

感謝這個有價值的code.it的作品 – user1514019 2012-07-10 20:49:09

首先，你必須找到你的郵政編碼的地理位置，你可以很容易地找到它使用gmaps api。然後使用「distanceTo」方法找到點之間的距離（您的地理位置和郵政編碼生成的地理點）。 distanceTo方法以米爲單位給出距離。
