This really isn't possible. It sounds like what you want is for the document to be destroyed after first reading (Mission Impossible style). That's not how the web works. A file that can be accessed over the web can be easily downloaded and opened offline. Certainly there are hacks around this, but they would be fairly involved to implement. I once created a Flash-based viewer that loaded another file that contained the actual document. Any tech-savvy user could still obtain the original document by examining the network traffic, but your average non-technical user wouldn't know how to do it. You do have options for enabling restrictions in a PDF, but the user will always be able to save it and re-open it later. Probably what you want to do is implement restrictions on the document and <a href="http://www.ahfb2000.com/webmaster_help_desk/showpost.php?s=fe92c1665e42feb127a847f54ca53d1a&p=38431&postcount=6" rel="nofollow">load it in an iframe</a> to prevent saving. You can implement print/copy restrictions as follows: <pre><code>$dompdf = new DOMPDF(); $dompdf->load_html($html); $dompdf->render(); $dompdf->get_canvas()->get_cpdf()->setEncryption('', 'ownerpass', array()); $dompdf->stream(); </code></pre> The parameters of setEncryption are: <ol> <li>string, user password (restrictions apply)</li> <li>string, owner password (unlocks document)</li> <li>array, strings indicating allowed actions when user password is supplied (e.g. print, copy). If left blank the user is limited to saving the document.</li> </ol>

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.
