Question

我有一个使用javascript，php和SQL查询的自定义PHP文件，但对于drupal并且很难实现它是全新的。我已经尝试过几次关注模块构建教程，但是对于细节的数量感到不知所措/压力，并且还没有引起我的青睐。是否有可能轻松地使我的文件在我的XAMPP环境中非常有效地进入drupal模块而不会过多地改变代码？如果是这样，我需要在PHP文件中进行哪些更改？

以下是我的PHP文件中的代码：

<?php
$server = 'localhost';$user = 'root';$database = 'transportation';$password = null;
$db = mysqli_connect($server, $user, $password, $database);
?>

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var map = null;
var infowindow = new google.maps.InfoWindow();
var markers = [

  <?php
  if (isset($_GET['routeselected'])) 
  {
  $result = mysqli_query($db, "SELECT * FROM STOP INNER JOIN RouteStop ON Stop.Stop_ID = RouteStop.Stop_ID WHERE RouteStop.Route_ID = " . (int)$_GET['routeselected'] . " AND RouteStop.Company_ID = " . (int)$_GET['companyselected']);
  while ($row = mysqli_fetch_array($result))
      echo "{\"title\": '".$row['Stop_ID']."', \"lat\": '".$row['Latitude']."', \"lng\": '".$row['Longitude']."', \"description\": '".$row['StopName']."'},";
  }
  ?>

];

window.onload = function () {

var mapOptions = {
    center: new google.maps.LatLng(
        parseFloat(markers[0].lat),
        parseFloat(markers[0].lng)),
    zoom: 13,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};
var path = new google.maps.MVCArray();
var service = new google.maps.DirectionsService();
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var poly = new google.maps.Polyline({map: map, strokeColor: '#F3443C'});

var lat_lng = new Array();
           for (i = 0; i < markers.length; i++) {
           var data = markers[i]
           var myLatlng = new google.maps.LatLng(data.lat, data.lng);
           lat_lng.push(myLatlng);
           var marker = new google.maps.Marker({
               position: myLatlng,
               map: map,
               title: data.title
           });
           (function (marker, data) {
               google.maps.event.addListener(marker, "click", function (e) {
                   infoWindow.setContent(data.description);
                   infoWindow.open(map, marker);
               });
           })(marker, data);
       }
for (var i = 0; i < markers.length; i++) {
    if ((i + 1) < markers.length) {
        var src = new google.maps.LatLng(parseFloat(markers[i].lat), 
                                         parseFloat(markers[i].lng));
        var des = new google.maps.LatLng(parseFloat(markers[i+1].lat), 
                                         parseFloat(markers[i+1].lng));
        service.route({
            origin: src,
            destination: des,
            travelMode: google.maps.DirectionsTravelMode.DRIVING
        }, function (result, status) {
            if (status == google.maps.DirectionsStatus.OK) {
                for (var i = 0, len = result.routes[0].overview_path.length; i < len; i++){
                    path.push(result.routes[0].overview_path[i]);
                }
                poly.setPath(path);
            }
        });
    }
}
} 

</script>

<?php
if (isset($_GET['companyselected'])) 
  {
  if ($result = mysqli_query($db, "SELECT DISTINCT RouteNum, RouteName FROM Route WHERE Company_ID = " . (int)$_GET['companyselected']))
  {
    $fields = mysqli_fetch_fields($result);

脏路1：你可以在body中创建一个带有php内容的节点（PHP过滤器模块），并使用你节点中的所有上述代码，希望这些代码能够正常工作

脏的方式2：如果你想将它包含在一个以上的页面中，你可以将上述逻辑与块而不是节点一起使用

模块方式：您必须提供有关您希望模块运行的准确程度的更多信息（例如，覆盖用户的配置文件页面以包含地图或创建一个块，您可以在模板中包含从管理中获取变量的块 - 结束或..等），但你的代码将不得不改变很多，你也应该使用drupal api（例如查询drupal数据库，访问变量等）。 Drupal模块采用（或至少应该采用）drupal API的优势，例如，而不是正常的php连接/查询数据库，您可以简单地（并且安全地）使用[db_query function]

Drupal - 轻松将自定义代码转换为drupal模块？
