    <p>I am using PHP's ZipArchive class to create a zip file containing photos and then serve it up to the browser for download. Here is my code:</p> <pre><code>/** * Grabs the order, packages the files, and serves them up for download. * * @param string $intEntryID * @return void * @author Jesse Bunch */ public static function download_order_by_entry_id($intUniqueID) { $objCustomer = PhotoCustomer::get_customer_by_unique_id($intUniqueID); if ($objCustomer): if (!class_exists('ZipArchive')): trigger_error('ZipArchive Class does not exist', E_USER_ERROR); endif; $objZip = new ZipArchive(); $strZipFilename = sprintf('%s/application/tmp/%s-%s.zip', $_SERVER['DOCUMENT_ROOT'], $objCustomer-&gt;getEntryID(), time()); if ($objZip-&gt;open($strZipFilename, ZIPARCHIVE::CREATE) !== TRUE): trigger_error('Unable to create zip archive', E_USER_ERROR); endif; foreach($objCustomer-&gt;arrPhotosRequested as $objPhoto): $filename = PhotoCart::replace_ee_file_dir_in_string($objPhoto-&gt;strHighRes); $objZip-&gt;addFile($filename,sprintf('/press_photos/%s-%s', $objPhoto-&gt;getEntryID(), basename($filename))); endforeach; $objZip-&gt;close(); header('Last-Modified: '.gmdate('D, d M Y H:i:s', filemtime($strZipFilename)).' GMT', TRUE, 200); header('Cache-Control: no-cache', TRUE); header('Pragma: Public', TRUE); header('Expires: ' . gmdate('D, d M Y H:i:s', time()) . ' GMT', TRUE); header('Content-Length: '.filesize($strZipFilename), TRUE); header('Content-disposition: attachment; filename=press_photos.zip', TRUE); header('Content-Type: application/octet-stream', TRUE); ob_start(); readfile($strZipFilename); ob_end_flush(); exit; else: trigger_error('Invalid Customer', E_USER_ERROR); endif; } </code></pre> <p>This code works really well with all browsers but IE. In IE, the file downloads correctly, but the zip archive is empty. When trying to extract the files, Windows tells me that the zip archive is corrupt. Has anyone had this issue before?</p> <p><strong>Edit</strong> Update: After suggestion from @profitphp, I changed my headers to this:</p> <pre><code>header("Cache-Control: public"); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: public"); //header("Content-Description: File Transfer"); //header("Content-type: application/zip"); header("Content-Disposition: attachment; filename=\"pressphotos.zip\""); //header("Content-Transfer-Encoding: binary"); header("Content-length: " . filesize($strZipFilename)); </code></pre> <p>Also, here is a screenshot of the error in Windows after opening with Firefox:</p> <p><img src="https://i.stack.imgur.com/7B2WA.png" alt="alt text"></p> <p>This error occurs in both IE and Firefox on Windows. It works fine in Mac. Also, in Windows, the filesize appears to be correct:</p> <p><img src="https://i.stack.imgur.com/1OblV.png" alt="alt text"></p> <p><strong>Edit #2</strong> This issue is sovled. See my answer below.</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.
