    <p>I have been trying to make a download page that would download different file formats (PDF, DOC, POWER POINT and images). This works with pdf, but the first problem is that sometimes it makes my whole system reboot or it redirects to other pages whose contents are not human readable. Secondly, the other file formats (MIME) that are not application/pdf would not just download, sometimes the pdf downloads but when I try to open it an error message would be displayed, saying its a bad file format. Below are the headers I use to make the download page.</p> <pre><code>header('Content-Type: application/{$_GET['mime']}'); header("Content-Disposition:attachment; filename='{$_GET['name']}'\n"); header("Content-Length:{$_GET['size']}\n"); header('Content-Transfer-Encoding: binary'); </code></pre> <p>The following are the various MIME I tried to allow:</p> <pre><code>$permitted = array('text/html', 'image/jpeg', 'image/png', 'image/jpg','image/gif', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'application/pdf', 'text/plain', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/vnd.openxmlformatsofficedocument.presentationml.presentation'); </code></pre> <p>Here's the code (almost) all together:</p> <pre><code>$flag = false; $filepath = $_GET['path'] . $_GET['name'] foreach($permitted as $value) { if($_GET['mime'] == $value) { $flag=true; break; } if($flag == true) { header('Content-Type: application/{$_GET['mime']}'); header("Content-Disposition:attachment; filename='{$_GET['name']}'\n"); header("Content-Length:{$_GET['size']}\n"); header('Content-Transfer-Encoding: binary'); readfile($filepath) } </code></pre> <p>I would appreciate all responses as I am using this for my project in school, Thanks....</p>

    2. COThis might not specifically solve it, but if you're trying to use single/double quotes or variables inside of strings, you should either use the correct quotes or escape the quotes, ex: `header('Content-Type: application/{$_GET['mime']}');` should instead be: `header("Content-Type: application/{$_GET['mime']}");`. Also, are you getting anything in your error logs that might be of use?

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.
