Retrieve data

Using the _get_option('my_map_field_id') method, you'll get (with a json_encode() display):

{
    "address": "3 rue Baudin, Levallois-Perret, France",
    "marker": {
        "id": "x",
        "url": "http:\/\/your_complete_url\/wp-content\/themes\/your_theme\/img\/my-marker.svg",
        "name": "my-marker"
    },
    "width": "500",
    "height": "200",
    "zoom": "14",
    "type": "ROADMAP",
    "options": {
        "dragndrop": "yes",
        "zoomcontrol": "yes",
        "overviewmapcontrol": "yes"
    },
    "enable": "yes",
    "json": "[{\"stylers\":[{\"saturation\":-100},{\"gamma\":0.8},{\"lightness\":4},{\"visibility\":\"on\"}]},{\"featureType\":\"landscape.natural\",\"stylers\":[{\"visibility\":\"on\"},{\"color\":\"#5dff00\"},{\"gamma\":4.97},{\"lightness\":-5},{\"saturation\":100}]}]"
