Cakephp 地理编码行为

Question

我一直在关注本教程。基本上我想从我拥有的表格中获取一个地址并将该地址放在谷歌地图上。该教程看起来非常简单，创建桌子位置，放入行为和模型等等。

只是有点困惑我实际上如何将其与现有的表格一起使用。我已经阅读了食谱中有关行为的部分，但对它们仍然有点困惑。主要是关于如何将教程集成到不在位置模型内的其他视图和控制器中？

Answer 1

首先，您需要将纬度/经度坐标添加到地址表中...

您可以使用围绕此 google 地图 api 调用的书写解析器来完成此操作：

http://maps.google.com/maps/api/geocode/xml?address=miami&sensor=false

一旦您的地址包含坐标，你所需要的只是传递坐标
到您视图中的 javascript 谷歌地图，只需复制源代码：

http://code.google.com/apis/maps/documentation/javascript/examples/map-simple.html

这是一个 cakephp 2.0 shell，用于创建

要运行的纬度/经度数据：“cake geo”

GeoShell.php：

<?php
class GeoShell extends Shell {

public $uses = array('Business');

public function main() {



    $counter = 0;
    $unique = 0;


    $temps = $this->Business->find('all', array(
        'limit' => 100
    ));

    foreach($temps as $t) {

            $address = $this->geocodeAddress($t['Business']['address']);

            print_r($address);

            if(!empty($address)) {
                $data['Business']['id'] = $t['Business']['id'];
                $data['Business']['lat'] = $address['latitude'];
                $data['Business']['lng'] = $address['longitude'];

                $this->Business->save($data, false);
                $unique++;
            }

    }

    $counter++;


    $this->out(' - Processed Records: ' . $counter . ' - ');
    $this->out(' - Inserted Records: ' . $unique . ' - ');

}


public function geocodeAddress($address) {

    $url = 'http://maps.google.com/maps/api/geocode/json?address=' . urlencode($address) . '&sensor=false';

    $response = @file_get_contents($url);

    if($response === false) {
        return false;
    }

    $response = json_decode($response);

    if($response->status != 'OK') {
        return false;
    }

    foreach ($response->results['0']->address_components as $data) {
        if($data->types['0'] == 'country') {
            $country = $data->long_name;
            $country_code = $data->short_name;
        }
    }

    $result = array(
        'latitude'  => $response->results['0']->geometry->location->lat,
        'longitude' => $response->results['0']->geometry->location->lng,
        'country' => $country,
        'country_code' => $country_code,
        'googleaddress' => $response->results['0']->formatted_address,
    );
    return $result;
}

}
