title: Render google map in wordpress, based on adress
body: <p>I have a wordpress site with a large number of pages, each page represent a physical location. Now for each page I would like to display a google map based on the address. 
  I know I can do this by installing a google map plugin, but that requires that I manually, for every post, create a location based on the address and add a shortcode to the post/page that results in a google map. This is a LOT of work for this site with hundreds of locations.</p>
  
  <p>I would like to be able to create an "address-custom-field" for each post programmatically.</p>
  
  <p>This is where I am now:</p>
  
  <pre><code>&lt;div id="map_canvas" style="width: 190px; height: 130px; margin-top: 5px;"&gt;&lt;/div&gt; 
  &lt;script type="text/javascript"
  src="http://maps.googleapis.com/maps/api/js?key=mykey&amp;sensor=false"&gt;
  &lt;/script&gt;
  &lt;script type="text/javascript"&gt;
  function initialize() {
  var myOptions = {
  center: new google.maps.LatLng(-34.397, 150.644),
  zoom: 8,
  mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("map_canvas"),
  myOptions);
  }
  &lt;/script&gt;
  </code></pre>
  
  <p>How do i change  center: new google.maps.LatLng(-34.397, 150.644), into an adress?</p>
