下面的代码使用Google的地理编码API获取地址/位置的坐标，它可以手动键入我在下面写下“地址在这里”的地址，然后适当地输出坐标。
<?php
function getCoordinates($address) {
$address = urlencode($address);
// set HTTP header
$headers = array(\'Content-Type: application/json\');
// Open connection
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, \'http://maps.google.com/maps/api/geocode/json?sensor=false&address=\' . $address);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
// Execute request
$result = curl_exec($curl);
// Close connection
curl_close($curl);
// get the result and parse to JSON
$json = json_decode($result);
$lat = $json->results[0]->geometry->location->lat;
$lng = $json->results[0]->geometry->location->lng;
return array($lat, $lng);
}
$coords = getCoordinates("ADDRESS GOES HERE ");
$coords = join(\',\', $coords);
?>
id现在想做的是使用自定义字段（ACF）将地址动态调用到“ADDRESS GOES HERE”。
包含地址的字段当前被调用到模板中，如下所示：
<?php if( get_field(\'address_line_1\') ): ?><?php the_title(); ?>, <?php the_field(\'address_line_1\', $post_id); ?>,<?php the_field(\'address_line_2\', $post_id); ?>, <?php the_field(\'town\', $post_id); ?>, <?php the_field(\'post_code\', $post_id); ?>, <?php the_field(\'country\', $post_id); ?><?php endif; ?>
在“地址在此处”位置使用上述字段的最佳方式是什么？
作为参考，curl脚本是https://colinyeoh.wordpress.com/2013/02/12/simple-php-function-to-get-coordinates-from-address-through-google-services/, 这似乎没有那么有效。

Insert Address fields into function
<?php
function getCoordinates($address) {
$address = urlencode($address);
// set HTTP header
$headers = array(\'Content-Type: application/json\');
// Open connection
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, \'http://maps.google.com/maps/api/geocode/json?sensor=false&address=\' . $address);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
// Execute request
$result = curl_exec($curl);
// Close connection
curl_close($curl);
// get the result and parse to JSON
$json = json_decode($result);
$lat = $json->results[0]->geometry->location->lat;
$lng = $json->results[0]->geometry->location->lng;
return array($lat, $lng);
}
$post_id = get_the_ID();
$title = get_the_title($post_id );
$address_line_1 = get_field( "address_line_1",$post_id );
$address_line_2 = get_field( "address_line_2",$post_id );
$town = get_field( "town",$post_id );
$post_code = get_field( "post_code",$post_id );
$country = get_field( "country",$post_id );
if($address_line_1!="")
{
$address_string = $title.",".$address_line_2.",".$town.",".$post_code.",".$country;
}
else
{
$address_string = "";
}
$coords = getCoordinates($address_string);
$coords = join(\',\', $coords);
?>
