    <p>I am new to working with the Facebook API and I have a question that I believe should be simple.</p> <p>I am setting up a TV screen for a store that will display a webpage. On the page I am going to display the current 'like count' of the store's facebook page. I know how to set it up to display the likes but is there an easy way to have the number auto-refresh when new people like the page WITHOUT refreshing the whole page. I guess I'm looking for it to be generated dynamically. I'm not sure how to go about this. I'm willing to do the research, I just need to be pointed in the right direction.</p> <p>Here's the code in the body of the page so far:</p> <pre><code>&lt;?php function fan_count($fan_ID) { $info = json_decode(file_get_contents('http://graph.facebook.com/' . $fan_ID)); echo $info-&gt;likes; } function fan_name($fan_ID) { $info = json_decode(file_get_contents('http://graph.facebook.com/' . $fan_ID)); echo $info-&gt;name; } ?&gt; &lt;div style="width:100px; height:100px; border:1px solid black;"&gt; Facebook Logo &lt;/div&gt; &lt;div class="fb_stats" id="fb_name"&gt; &lt;?php fan_name(PAGE_ID)?&gt; &lt;/div&gt; &lt;div class="fb_stats" id="fb_likes"&gt; &lt;?php fan_count(PAGE_ID)?&gt; &lt;/div&gt; </code></pre> <p>Thanks for any help you can provide!</p> <h2>EDIT</h2> <p>Alright, here is my updated code per the answer below. I can't get the PHP on the main page to work (I'll worry about the reloading once I have this bit set up correctly). I'm just looking to grab the like count for simplicities sake and I'll build from there. Here's my code (I'm using 'cocacola' as an example; vanity URLs are compatible with the Facebook graph btw):</p> <pre><code>&lt;?php class fanpage { public $fan_ID; public $info; function __construct($fan_ID) { $this-&gt;fan_ID = $fan_ID; $this-&gt;info = json_decode(file_get_contents('http://graph.facebook.com/' . $fan_ID)); } function fan_count() { echo $info-&gt;likes; } } $fp = new fanpage(cocacola); ?&gt; &lt;div style="width:100px; height:100px; border:1px solid black;"&gt; Facebook Logo &lt;/div&gt; &lt;div class="fb_stats" id="fb_likes"&gt; &lt;?php $fp-&gt;fan_count()?&gt; &lt;span style="font-size:20px; position:absolute; top:400px;"&gt;Total Likes&lt;/span&gt; &lt;/div&gt; </code></pre> <p>Does it possibly have anything to do with $info being defined in one function and trying to be called in another? Thanks for the help!</p>

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.
