[Plugin: MapPress Easy Google Maps] Mappress API

Hi,

I think that error may be because your address must be geocoded. You need to geocode the markers before you call display().

Take a look at the geocode() function and also the save_post() function to see how to handle the goecoding results, along with google’s documentation:
https://code.google.com/apis/maps/documentation/geocoding/

If you just want to display a map from addresses in a custom field – if you’re patient, I’m currently working on adding this into the plugin itself, but it may be a while before I get it done.

How do I dynamically get the map’s ID?

I also would love the ability to generate a map using the custom fields. I already have custom fields for address, city, state, zip.
I tried to pass this to Mappress via:

$street = get_post_meta($post->ID, 'address', true);
                $city = get_post_meta($post->ID, 'city', true);
                $state = get_post_meta($post->ID, 'state', true);
                $zip = get_post_meta($post->ID, 'zip', true);
                $address = $street.' '.$city.' '.$zip;

..then…

$mymap = new Mappress_Map(array("width" => 425));
                                $mypoi = new Mappress_Poi( array( 'address' => $address, 'title' => get_the_title($post->ID), 'body' => $address ) );
                                $mypoi->geocode();
                                $mymap->pois = array($mypoi);
                                $mymap->display();

Borrowed some of your code as well OP. ??
But it does not work.
BTW This plug-in kicks ass!

Ok.. I installed another plug-in that geocodes based on custom fields(address,stree,city,zip) and creates two new custom fields(lat,lgn). I tried using the code suggested on the MapPress page with both the data from these fields and manually substituting the actual lat and lgn. MapPress wouldnot display the map.
So…

$mymap = new Mappress_Map(array("width" => 425, "height" => 350));
$mypoi = new Mappress_Poi(array( "point" => array("lat" => 34.0213670, "lng" => -81.3380449)));
$mymap->pois = array($mypoi);
$mymap->display();

..does not work.
What are we doing wrong here?

well

I have had a look at the geocode function and this is what I get when sending the datas directly to google through

https://maps.google.com/maps/api/geocode/json?address=8bis avenue du palais des expositions, 66000 perpignan&sensor=false&output=json&region=FR&language=FR

returns

{

}
}
},

} ]
}

which seems absolutely perfect.

So it should work with this php code:

$mymap = new Mappress_Map( array( “width” => 600, “height” => 450 ) );
var_dump($address);
$mypoi = new Mappress_Poi( array( “title” => “”, “body” => “”, “point” => array(“address” => $address[0]) ) );
$mypoi->geocode( );
$mymap->pois = array($mypoi);
$mymap->display( );

the var dump returns:

array(1) { [0]=> string(63) “8bis, avenue du palais des expositions, 66000 Perpignan, France” }

but my POI doesn’t show up ??

Any other hint ?

Sincerely
Olivier

Sorry, the proper php code should be:

$mymap = new Mappress_Map( array( “width” => 600, “height” => 450 ) );
$mypoi = new Mappress_Poi( array( ‘address’ => $address[0], ‘title’ => “”, ‘body’ => $address[0] ) );
$mypoi->geocode( );
$mymap->pois = array($mypoi);
var_dump($mymap->pois);
$mymap->display( );

The pois var dump returns:

array(1) { [0]=> object(Mappress_Poi)#187 (8) { [“point”]=> array(2) { [“lat”]=> float(42.7047338) [“lng”]=> float(2.8932853) } [“title”]=> string(34) “8 Avenue du Palais des Expositions” [“titleUrl”]=> NULL [“body”]=> string(23) “66000 Perpignan, France” [“address”]=> string(63) “8bis, avenue du palais des expositions, 66000 Perpignan, France” [“correctedAddress”]=> string(59) “8 Avenue du Palais des Expositions, 66000 Perpignan, France” [“iconid”]=> NULL [“viewport”]=> array(2) { [“sw”]=> array(2) { [“lat”]=> float(42.7015923) [“lng”]=> float(2.8901326) } [“ne”]=> array(2) { [“lat”]=> float(42.7078876) [“lng”]=> float(2.8964279) } } } }

which is lot better as the lat and lng datas are there…

but still no map

Hi upyup,

It took me a while realize that you forgot to put the echo before $mymap->display( ); and you can remove the var_dump($mymap->pois);

It should look like the following :

$mymap = new Mappress_Map( array( "width" => 600, "height" => 450 ) );
$mypoi = new Mappress_Poi( array( 'address' => $address[0], 'title' => "", 'body' => $address[0] ) );
$mypoi->geocode( );
$mymap->pois = array($mypoi);
echo $mymap->display( );
