Seperate directory reading

Peuplarchie

Good day to you all,
I was wondering how to seperate the result of a direcory read.
Example, I know the files will be images.

How can I show the portrait first and then landscape second ?

here is my code :



<html>
<head>

<SCRIPT language="JavaScript">
<!--
if (document.images)
{
  preload_image = new Image(25,25); 
<?PHP
//  directory name sent by url
$dir = $_GET['dir'];
$file = $_GET['file'];

//define the path as relative
$path = $dir."".$file;

//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

echo "Directory Listing of $path<br/>";

//running the while loop
while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")

  echo "preload_image.src=\"http://test.peuplies.info/PHP/Photos_gallery/".$path."/".$file.""; 

}

echo "} //-> </script> </head> <body><center>";



while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")

  echo "<img src=\"".$path."/".$file."\" width=\"50px\">"; 

}







//closing the directory
closedir($dir_handle);


?>



</center>

</body>
</html>

Thanks!

Unfortunately you'd have to change the filenames on the system since [man]readdir/man will return the list as they are listed on the filesystem.

Typically in cases like this a number is typically prepended to the filename to delineate sorting order. Just remember that files will be listed like:

1__file.txt
10__file.txt
11__file.txt
2__file.txt
3__file.txt
4__file.txt
43__file.txt
44__file.txt

So you'll want to make sure that you number them with preceeding 0's.

001__file.txt
002__file.txt
003__file.txt
004__file.txt
010__file.txt
011__file.txt
043__file.txt
044__file.txt

Of course you could always store the info in array's and then sort the array the way you want.
