php - wordpress 与 google map API 不起作用

我在 WordPress 上使用 PHP 和 MYSQL 以及 Google Map API,从 MYSQL 数据库检索数据,并根据从数据库检索到的坐标在 Google map 上显示标记。

问题是网页中显示注释,谁能告诉我我的代码错误在哪里?

代码:

<?php
/*
Template Name: MAP2
*/

get_header();
?>


<!DOCTYPE html>
<html>
<head>
<title>Custom Markers</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
height: 100%;
margin: 0;
padding: 0;
}
</style>

</head>
<body>
<div id="map"></div>
<script>

var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 16,
center: new google.maps.LatLng(-33.91722, 151.23064),
mapTypeId: 'roadmap'
});

var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
parking: {
icon: iconBase + 'parking_lot_maps.png'
},
library: {
icon: iconBase + 'library_maps.png'
},
info: {
icon: iconBase + 'info-i_maps.png'
}
};

function addMarker(feature) {
var marker = new google.maps.Marker({
position: feature.position,
icon: icons[feature.type].icon,
map: map
});
}

var features =
{
<?php
global $wpdb;
$prependStr ="";
foreach( $wpdb->get_results("SELECT * FROM site_coordinates2") as $key => $row)
{
$latitude = $row->latitude;
$longitude = $row->longitude;
$info = $row->siteID;
echo $prependStr;
?>
{

position: new google.maps.LatLng(<?php echo $latitude ?>, <?php echo $latitude ?>),
type: '<?php echo $info;?>'
}
<?php
$prependStr =",";
}


?>
}
</script>

<script async defer
src="https://maps.googleapis.com/maps/api/js?key=***************callback=initMap">
</script>
</body>
</html>

<?php
get_footer();
?>

最佳答案

我认为问题出在设置高度上。请参阅Here

但在我的情况下,将特定像素设置为映射 div。就像这样#map {min-height: 600px;}
