    <p>This is usually done by routing all requests to a single entry point (a file that executes different code based on the request) with a rule like:</p> <pre><code># Redirect everything that doesn't match a directory or file to index.php RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule .* index.php [L] </code></pre> <p>This file then compares the request (<code>$_SERVER["REQUEST_URI"]</code>) against a list of routes - a mapping of a pattern matching the request to a controller action (in MVC applications) or another path of execution. Frameworks often include a route that can infer the controller and action from the request itself, as a backup route.</p> <p>A small, simplified example:</p> <pre><code>&lt;?php // Define a couple of simple actions class Home { public function GET() { return 'Homepage'; } } class About { public function GET() { return 'About page'; } } // Mapping of request pattern (URL) to action classes (above) $routes = array( '/' =&gt; 'Home', '/about' =&gt; 'About' ); // Match the request to a route (find the first matching URL in routes) $request = '/' . trim($_SERVER['REQUEST_URI'], '/'); $route = null; foreach ($routes as $pattern =&gt; $class) { if ($pattern == $request) { $route = $class; break; } } // If no route matched, or class for route not found (404) if (is_null($route) || !class_exists($route)) { header('HTTP/1.1 404 Not Found'); echo 'Page not found'; exit(1); } // If method not found in action class, send a 405 (e.g. Home::POST()) if (!method_exists($route, $_SERVER["REQUEST_METHOD"])) { header('HTTP/1.1 405 Method not allowed'); echo 'Method not allowed'; exit(1); } // Otherwise, return the result of the action $action = new $route; $result = call_user_func(array($action, $_SERVER["REQUEST_METHOD"])); echo $result; </code></pre> <p>Combined with the first configuration, this is a simple script that will allow you to use URLs like <code>domain.com/about</code>. Hope this helps you make sense of what's going on here.</p>

    1. COin your code you forget: to add the url in the GET params: `RewriteRule (.*) index.php?url=$1 [QSA,L]`

    2. COHi Olivier, it's not really necessary to pass the url as a parameter as it's available in `$_SERVER['REQUEST_URI']`.

    3. COAre you *sure* that it won't be the final rewritten URL (i.e. `$_SERVER['REQUEST_URI']`==`index.php`)?

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).
