    <p>Coles Notes version:</p> <p><code>index.php?map_id=foo</code> is loaded into iframe on www.not-my-domain.com. index sets <code>SESSION['map_id']</code> = foo. Flash file tries to get <code>SESSION['map_id']</code> thru Authenticate.php, but Authenticate.php has no values set for <em>any</em> <code>SESSION</code> varaibles.</p> <p>-- Only first-load, cross domain issue.</p> <p>Verbose:</p> <p>I have an index while where I set: <code>SESSION['map_id'] = foo</code></p> <p>The index file then loads a flash file. When initialized, the flash accesses an 'Authenticate.php' file which echo's out the <code>SESSION['map_id']</code> and is loaded into flash via <code>LoadVars</code>. Flash then displays the appropriate data. <em>This step cannot be done another way</em></p> <p>This all works just fine on our main site. The issue comes when we try to port out to other sites by providing iframe embed codes:</p> <pre><code>&lt;iframe src="http://www.mydomain.com/?map_id=foo&amp;code=bar" ... &gt;&lt;/iframe&gt; </code></pre> <p>On a fresh load of the embed code from another site (www.anotherdomain.com), it seems that the <code>SESSION</code> variables have been destroyed, as flash simply says they are empty. ( <code>$map_id</code> outputs a blank )</p> <p>The index file will still properly echo <code>$map_id</code> as 'foo', it just seems the 'Authenticate.php' file cannot access the <code>SESSION</code> varaibles.</p> <p>I have ensured <code>session_start()</code> is present in all appropriate files.</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.
