Hi
I am trying to write a script that makes a tree style menu out of my site's directory structure. I have the script written, and it works but I'm pretty new to
PHP and would appreciate it if anyone could have a quick look at the script to see if there would be a more efficient way of doing this.
Basically the script loops through the directories and makes them a link that toggles (using
js) the display of any directories below it. If a directory contains a directory (or file) named 75DPI then it instead becomes a link back to the index with the filepath to that directory appended to the URL. Hope that makes sense!
- PHP: Select all
function getNav($path, $i)
{
$nav = opendir($path);
while($file = readdir($nav))
{
if($file != '.' && $file != '..' && $file != '300DPI')
{
if (is_dir($path.'/'.$file))
{
$dirContents = scandir($path.'/'.$file);
if (in_array('75DPI', $dirContents))
{
echo '<li><a href="index.php?path='.$path.'/'.$file.'">'.$file.'</a></li>'."\n";
$i++;
}
else
{
echo '<li><a href="javascript: expand(\'dir'.$i.'\');">+'.$file.'</a></li>'."\n";
echo '<ul id="dir'.$i.'">'."\n";
$i++;
getNav($path.'/'.$file, $i);
echo '</ul>'."\n";
}
}
$i++;
}
}
closedir($nav);
}
getNav('Img', 1);
