    <p>Here's a function I (Apparently Others?!!?) developed to do just that, it's a meaty function but it checks and does everything. To call it is simple though, the important part. I have this inside a class but you can just make it a php function as there is no other class functions it depends on. Hope this helps you.</p> <pre><code> public static function output_file($path, $filename, $mime_type='') { $err = 'Sorry, the file you are requesting is unavailable.'; $filename = rawurldecode($filename); // check that file exists and is readable if (file_exists($path) &amp;&amp; is_readable($path)) { /* Figure out the MIME type (if not specified) */ $known_mime_types=array( "pdf" =&gt; "application/pdf", "txt" =&gt; "text/plain", "html" =&gt; "text/html", "htm" =&gt; "text/html", "exe" =&gt; "application/octet-stream", "zip" =&gt; "application/zip", "doc" =&gt; "application/msword", "xls" =&gt; "application/vnd.ms-excel", "ppt" =&gt; "application/vnd.ms-powerpoint", "gif" =&gt; "image/gif", "png" =&gt; "image/png", "jpeg"=&gt; "image/jpg", "jpg" =&gt; "image/jpg", "php" =&gt; "text/plain" ); if($mime_type==''){ $file_extension = strtolower(substr(strrchr($filename,"."),1)); if(array_key_exists($file_extension, $known_mime_types)){ $mime_type=$known_mime_types[$file_extension]; } else { $mime_type="application/force-download"; }; }; @ob_end_clean(); //turn off output buffering to decrease cpu usage if(ini_get('zlib.output_compression')) { //otherwise the filesize is way off ini_set('zlib.output_compression', 'Off'); } // get the file size and send the http headers $size = filesize($path); header("Content-Type: $mime_type"); header('Content-Disposition: attachment; filename="'.$filename.'"'); header('Content-Transfer-Encoding: binary'); header('Accept-Ranges: bytes'); header('Cache-control: private'); header('Pragma: private'); header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // multipart-download and download resuming support if(isset($_SERVER['HTTP_RANGE'])) { list($a, $range) = explode("=", $_SERVER['HTTP_RANGE'], 2); list($range) = explode(",", $range, 2); list($range, $range_end) = explode("-", $range); $range=intval($range); if(!$range_end) { $range_end = $size-1; } else { $range_end = intval($range_end); } $new_length = $range_end-$range+1; header("HTTP/1.1 206 Partial Content"); header("Content-Length: $new_length"); header("Content-Range: bytes $range-$range_end/$size"); } else { $new_length = $size; header("Content-Length: " . $size); } /* output the file itself */ $chunksize = 1*(1024*1024); //may want to change this $bytes_send = 0; if ($file = fopen($path, 'r')) { if(isset($_SERVER['HTTP_RANGE'])) { fseek($file, $range); } while(!feof($file) &amp;&amp; (!connection_aborted()) &amp;&amp; ($bytes_send&lt;$new_length)) { $buffer = fread($file, $chunksize); print($buffer); //echo($buffer); // is also possible flush(); $bytes_send += strlen($buffer); } fclose($file); } else { die($err); } } else { die($err); } die(); } </code></pre> <p>To use it would be something like this.</p> <pre><code>$path = '/var/www/site/httpdocs/upload/private/myfile.txt'; $dl_filename = 'NDA_'.time(); $mime_type = 'doc'; output_file($path,$dl_filename,$mime_type); </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.
