Body
The error "Some data has already been output, can't send PDF file" appears because Magento has already sent the header output. Look at <a href="http://php.net/manual/en/function.header.php" rel="nofollow noreferrer">http://php.net/manual/en/function.header.php</a> for further informations. So the Output() function of FPDF is also sending header informations and it declares the 'Content-Type' to 'application/pdf'. The main problem here is that you cannot just put a PDF file between HTML tags. PDF is an own format and needs a diffrent presantation mechanism than HTML. Like in the example link you gave the PDF file is embeded by the embed-tag with the right Content-Type declaration: <pre><code><embed width="100%" height="100%" name="plugin" src="http://milton.bommelme.com/fpdf/pddf.php" type="application/pdf"> </code></pre> There are also other ways to embed a PDF file in HTML: <a href="https://stackoverflow.com/questions/291813/recommended-way-to-embed-pdf-in-html">Recommended way to embed PDF in HTML?</a> EDIT: For example you can create two view actions. The first one renders the HTML. Inside the HTML the embed-tag calls the second action which will generate the PDF. I don't think this is the best solution,but it should work easily: <pre><code>class Foo_Pdf_Controller_SomeController extends Mage_Core_Controller_Front_Action { public function viewAction() { // View stuff } public function getPdfAction() { // create pdf $fpdf->output(); } } </code></pre> The embed-tags calls the getPdf() action: <pre><code><embed width="100%" height="100%" name="plugin" src="url_to_getPdf_action" type="application/pdf"> </code></pre>

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.
