    <p>the question is kinda old, but this is how I solved the blank page from getHtmlFromPage method. Instead of using the getHtmlFromPage method, I simply used curl to get the page I want to pdf and then passed that to the html2pdf as a string an voila!</p> <pre><code>require_once 'path_to_html2pdf/html2pdf/html2pdf.class.php'; $str_url = 'http://your_url_here.php'; $str_content = get_page($str_url); //get_page can be file_get_contents if your server allows for that function to open a url or a curl function that im posting down below try{ $html2pdf = new HTML2PDF('P', 'A4', 'es'); $html2pdf-&gt;pdf-&gt;SetDisplayMode('fullpage'); $html2pdf-&gt;writeHTML($str_content ); $html2pdf-&gt;Output('your_file_name.pdf', 'D'); //The 'D' option downloads the pdf instead of just showing it on screen } catch(HTML2PDF_exception $e) { echo $e; exit; } //Here is the curl function for get_page function get_page($str_url){ if(strpos($str_url, 'http://') === false){ return file_get_contents($str_url); }else{ if(ini_get('allow_url_fopen')){ return file_get_contents($str_url); }else{ $curl = curl_init(); curl_setopt ($curl, CURLOPT_REFERER, strFOARD); curl_setopt ($curl, CURLOPT_URL, $str_url); curl_setopt ($curl, CURLOPT_TIMEOUT, 30); curl_setopt ($curl, CURLOPT_USERAGENT, sprintf("Mozilla/%d.0",rand(4,5))); curl_setopt ($curl, CURLOPT_HEADER, 0); curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($curl, CURLOPT_SSL_VERIFYPEER, 0); $html = curl_exec ($curl); curl_close ($curl); return $html; } } } </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.
