Reply To: How to show tree view with 100 pages in a folder as tree view on browser.

[Beverleyh]

You could build a sortable file list using PHP’s glob() function http://php.net/manual/en/function.glob.php to get all the pages in a folder;

$files = glob('path/to/pages/*.{htm,html,php}', GLOB_BRACE); // get all pages from a folder
/* perform additional sort here */
echo "<ul>\n";
foreach ($files as $file) { 
    echo "<li>$file</li>\n"; 
    } 
echo "</ul>\n";

This would list the pages. You’d need to manipulate the output of ‘$file’ some more, and echo out whatever HTML markup you need to build your tree view (using CSS to dress it up).

For the sort feature, you could do it with PHP or JavaScript. With PHP you could pass a query string via a link on the page;

<a href="?sort=az">A-Z</a> | <a href="?sort=za">Z-A</a>

And use PHP’s GET to identify which sort direction has been selected – something like;

$sort = $_GET['sort'];
if ( $sort == 'az' ){ sort($files); }
else if ( $sort == 'za' ){ rsort($files); }

This code would go where /* addition sort */ is indicated in the PHP block earlier.

Alternatively, you could sort the files with JavaScript using one of the many available scripts / plugins that you can source online http://www.jqueryrain.com/demo/jquery-sortable-sort/
Match your echo’d markup to that required by your chosen plugin.
