    <p>I am trying to build a router function to properly match incoming URI's and match them to an array of stored system URI's. I also have wildcards '(:any)' and '(:num)' similar to CodeIgniter. </p> <p>Basically, I am trying to get the 'admin/stats/(:num)' entry to match on both 'admin/stats' and admin/stats/1'.</p> <p>While the script is starting I grab all paths from a separate array and use a foreach to save each path: </p> <pre><code>route('admin/stats/(:num)', array('#title' =&gt; 'Statistics',...)); </code></pre> <p>The function is:</p> <pre><code>function route($path = NULL, $options = NULL) { static $routes; //If no arguments are supplied, return all routes stored. if(!isset($path) &amp;&amp; !isset($options)) { return $routes; } //return options for path if $path is set. if(isset($path) &amp;&amp; !isset($options)) { //If we have an exact match, return it. if(array_key_exists($path, $routes)) { return $routes[$path]; } //Else, we need to use RegEx to find the correct route options. else { $regex = str_replace('/', '\/', $path); $regex = '#^' . $regex . '\/?$#'; //I am trying to get the array key for $route[$path], but it isn't working. // route_replace('admin/stats/(:num)') = 'admin/stats/([0-9]+)'. $uri_path = route_replace(key($routes[$path])); //route_replace replaces wildcards for regex. if(preg_match($regex, $uri_path)) { return $routes[$path]; } } } $routes[$path] = $options; return $routes; } </code></pre> <p>Route replace function:</p> <pre><code>function route_replace($path) { return str_replace(':any', '.+', str_replace(':num', '[0-9]+', $path)); } </code></pre> <p>A key/value pair in the $routes array looks like:</p> <pre><code>[admin/stats/(:num)] =&gt; Array ( [#title] =&gt; Statistics //Page title [#access] =&gt; user_access //function to check if user is authorized [#content] =&gt; html_stats //function that returns HTML for the page [#form_submit] =&gt; form_stats //Function to handle POST submits. ) </code></pre> <p>Thanks for the help. This is my first router and I am not that familiar in making proper Regex's. </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.
