Hi there

I am trying to display the location on a user’s map in his frontend profile.
The issue is that the map is shown in gray.
I pass the code that I have implemented:

In css:

.acf-map {
    width: 100%;
    height: 400px;
    border: #ccc solid 1px;
    margin: 20px 0;
}

.acf-map img {
   max-width:inherit !important;
}

In js:

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCEtGGcK-UdAY7HpEnNxwRTywZlvBM0p1U"></script>
<script type="text/javascript">
(function($) {

/*
*  new_map
*
*  This function will render a Google Map onto the selected jQuery element
*
*  @type    function
*  @date	8/11/2013
*  @since	4.3.0
*
*  @param	$el (jQuery element)
*  @return	n/a
*/

function new_map( $el ) {
	
	// var
	var $markers = $el.find('.marker');
	
	
	// vars
	var args = {
		zoom		: 16,
		center		: new google.maps.LatLng(0, 0),
		mapTypeId	: google.maps.MapTypeId.ROADMAP
	};
	
	
	// create map	        	
	var map = new google.maps.Map( $el[0], args);
	
	
	// add a markers reference
	map.markers = [];
	
	
	// add markers
	$markers.each(function(){
		
    	add_marker( $(this), map );
		
	});
	
	
	// center map
	center_map( map );
	
	
	// return
	return map;
	
}

/*

*
*  This function will add a marker to the selected Google Map
*
*  @type	function
*  @date	8/11/2013
*  @since	4.3.0
*
*  @param	$marker (jQuery element)
*  @param	map (Google Map object)
*  @return	n/a
*/

function add_marker( $marker, map ) {

	// var
	var latlng = new google.maps.LatLng( $marker.attr('data-lat'), $marker.attr('data-lng') );

	// create marker
	var marker = new google.maps.Marker({
		position	: latlng,
		map			: map
	});

	// add to array
	map.markers.push( marker );

	// if marker contains HTML, add it to an infoWindow
	if( $marker.html() )
	{
		// create info window
		var infowindow = new google.maps.InfoWindow({
			content		: $marker.html()
		});

		// show info window when marker is clicked
		google.maps.event.addListener(marker, 'click', function() {

			infowindow.open( map, marker );

		});
	}

}

/*
*  center_map
*
*  This function will center the map, showing all markers attached to this map
*
*  @type	function
*  @date	8/11/2013
*  @since	4.3.0
*
*  @param	map (Google Map object)
*  @return	n/a
*/

function center_map( map ) {

	// vars
	var bounds = new google.maps.LatLngBounds();

	// loop through all markers and create bounds
	$.each( map.markers, function( i, marker ){

		var latlng = new google.maps.LatLng( marker.position.lat(), marker.position.lng() );

		bounds.extend( latlng );

	});

	// only 1 marker?
	if( map.markers.length == 1 )
	{
		// set center of map
	    map.setCenter( bounds.getCenter() );
	    map.setZoom( 16 );
	}
	else
	{
		// fit to bounds
		map.fitBounds( bounds );
	}

}

/*
*  document ready
*
*  This function will render each map when the document is ready (page has loaded)
*
*  @type	function
*  @date	8/11/2013

*

*  @return	n/a
*/
// global var
var map = null;

$(document).ready(function(){

	$('.acf-map').each(function(){

		// create map
		map = new_map( $(this) );

	});

});

})(jQuery);
</script>

In the php:

<?php 
$location = get_field('location','user_'. $vendor_id);
if( !empty($location) ):
?>
<div class="acf-map">
	<div class="marker" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>"></div>
</div>
<?php endif; ?>

NOTE: I use the WC Vendors plugin.

Sorry for my English, its a Google Translation..

Thanks,

Hi @agenciazaro

The Google map API will not work as expected if initialized on a hidden element. When the element is show, the map will not display. Please try and trigger the ‘resize’ event on the map variable after the map element is visible.

// popup is shown and map is not visible
google.maps.event.trigger(map, 'resize');

Hi. Thanks for your answer!
Sorry but I do not understand where I have to put that code. I do not understand anything about js haha.
Could you specifically tell me where I should place that code?

Thank you again!

Hi @agenciazaro

You should call the code after the map is created, preferably on this line:

$(document).ready(function(){

	$('.acf-map').each(function(){

		// create map
		map = new_map( $(this) );
                // popup is shown and map is not visible
                google.maps.event.trigger(map, 'resize');

	});

});

Hi James – thanks for your response here. I’ve got the same issue, the map is displaying grey and buggy. You can see mine here: http://www.coolbreeze2200.com

I’ve tried the above but my .js code is just slightly different, and I don’t know enough JS to make the adjustment. My code looks like this:

$(document).ready(function(){
 
 $('.acf-map').each(function(){
 
 		// create map
		map = new_map( $(this) );
               
 render_map( $(this) );
 
 });
 
});

How would I alter your above solution accordingly? Or is there another reason for the grey box I may be missing?

Thanks again,
Brian
