    <p>Please check the examples on google maps utilities library page (<a href="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/docs/examples.html" rel="nofollow">link</a>).</p> <p>But basically to add instance of an object (a marker) to an array you have to define the array first so you need to do the <code>var markers = [];</code> above the loop where you create the markers. And then as you create the markers you have to add them to the markers array by calling the <code>push</code> method of an array (while you are at it go to MDN and read about arrays! if you want to learn it's good time to start there - there is a tutorial about JS there as well (<a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array" rel="nofollow">link</a>).</p> <p>So inside of the <code>foreach</code> loop afer you've defined a marker just add it to the array <code>markers.push(marker);</code> This will make the markers available for the <code>MarkerCluster</code> initialization.</p> <p>In a longer term when you figure out javascript a bit better you'll probably want to replace this part with either passing data as JSON object to the DOM so methods can handle it or even better - have the data for markers be retrieved with ajax query. But one step at a time I guess :)</p> <p>Maybe try the fun interactive tutorials at the <a href="http://www.codecademy.com/" rel="nofollow">www.codecademy.com</a>? They are quite basic but seems like that's exactly what you need </p> <p>EDIT:</p> <pre><code>var marker, markers = []; &lt;?php foreach ($cluster_location as $location) { ?&gt; marker = new google.maps.Marker({'position': &lt;?php echo $location;?&gt;}); markers.push(marker); &lt;? } ?&gt; </code></pre>

    2. COcheck the edit in my reply - you've outputted curly bracers to HTML and it produces invalid JS code. Try if it works and let me know :) I've also moved the declaration of marker variable out of the loop so it gets declared only once.

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
