    <p>I've accessed the Facebook Graph API to get a JSON object representing the latest posts on my feed (my Facebook wall). I then saved it into a MongoDB collection called feeds using the PHP Mongo Driver.</p> <pre><code>//$post['feed']['data'] contains the Facebook JSON object of wall posts //create a mongo instance $mongo = new Mongo(); //access the feeds collection $feeds = $mongo-&gt;changeup-&gt;feeds; //dump the feed right into mongo $feeds-&gt;insert($post['feed']['data']); </code></pre> <p>This is what one of the arrays looks like after reading back the whole object that was placed into mongo. </p> <p>I'm only showing you one, but it gives me several more, each indexed, the next one is [1] => Array() and so on... some are structured differently, as some contain the [story] field, others contain the [message] field, and some contain both.</p> <pre><code>Query: $cursor = $feeds-&gt;find(); foreach ( $cursor as $feed ) { print_r($feed); } Result: [0] =&gt; Array ( [id] =&gt; 505212695_10150696450097696 [from] =&gt; Array ( [name] =&gt; John Doe [id] =&gt; 505212695 ) [story] =&gt; "Text of a story I posted on my wall..." [story_tags] =&gt; Array ( [38] =&gt; Array ( [0] =&gt; Array ( [id] =&gt; 15212444 [name] =&gt; John Doe [offset] =&gt; 38 [length] =&gt; 10 [type] =&gt; user ) ) ) [type] =&gt; status [application] =&gt; Array ( [name] =&gt; Share_bookmarklet [id] =&gt; 5085647995 ) [created_time] =&gt; 2012-04-04T05:51:21+0000 [updated_time] =&gt; 2012-04-04T05:51:21+0000 [comments] =&gt; Array ( [count] =&gt; 0 ) ) </code></pre> <p>The problem is that I don't want to just find the entire collection, I want to find only those arrays that have say [message] and [story] fields, and then just find their contents and nothing else.</p> <p>I'm trying to receive a subset, two levels deep:</p> <pre><code>//this works, however, I'm only able to get the 0 array $cursor = $feeds-&gt;find( array(), array('0.story' =&gt; true) ); </code></pre> <p>How do I filter by all arrays?</p> <p>I want my end result to look like this:</p> <pre><code>Array ( [_id] =&gt; MongoId Object ( [$id] =&gt; 4f7db4dd6434e64959000000 ) [0] =&gt; Array ( [story] =&gt; "Text of a story I posted on my wall..." ) [1] =&gt; Array ( [story] =&gt; "Text of a story I posted on my wall..." ) [2] =&gt; Array ( [story] =&gt; "Text of a story I posted on my wall..." [message] =&gt; "In this case message text exists as well..." ) [3] =&gt; Array ( [message] =&gt; "Text of a message I posted on my wall..." ) etc... ) </code></pre>

Guidance
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).
