    <p>I have a class that is included in a bunch of other scripts in different directories. Occasionally, this class will need to issue a redirect to another file that is located in the same directory. I am having trouble getting this to work in a consistent manner.</p> <p>For instance:</p> <pre><code>// file.php require('../class/include.php'); // include.php if(/* some condition */) { $mydir = '...'; // should be '../class' in this example header("Location: $mydir/setup.php"); die(); } </code></pre> <p>I have done the following with promising results, but it doesn't seem to always work and I am not sure if I am using the server variables wrong or if the configuration isn't correct for the instances that don't work.</p> <pre><code>$len = strlen($_SERVER['DOCUMENT_ROOT']); $mydir = str_replace('\\', '/', __FILE__); // switch slashes for Windows systems $mydir = substr($mydir, $len, strrpos($mydir, '/') - $len + 1); </code></pre> <p><strong>NOTE</strong> I want the URL, the path doesn't help because I can't redirect to <code>/var/wwwroot/some/directory</code> or <code>C:\domains\mydomain\some\directory</code></p> <p>This may be more a question of <code>$_SERVER['DOCUMENT_ROOT']</code>. Notice I am stripping off the length of <code>$_SERVER['DOCUMENT_ROOT']</code> from <code>__FILE__</code> to get the web accessible portion.</p> <p><strong>EDIT</strong></p> <p>To make things a little simpler, is there a way to get the equivalent of <code>$_SERVER['REQUEST_URI']</code> or <code>$_SERVER['PHP_SELF']</code> for the included file rather than the parent file?</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
