Question

I am trying to iterate through a directory and display all the pictures inside. I got it to work until I added Jquery/ajax into the equation.. Somehow the path is getting duplicated along the way so I get this error (you can see where it is duplicated):

Fatal error: Uncaught exception 'UnexpectedValueException' with message 'DirectoryIterator::__construct(images/gallery/album1,images/gallery/album1) [<a href='directoryiterator.--construct'>directoryiterator.--construct</a>]: The system cannot find the path specified

I can not for the life of me figure out why it is coming out like that…contruct(images/gallery/album1,images/gallery/album1) should be construct(images/gallery/album1)

PHP:

$album = $_POST['album'];
$dir = new DirectoryIterator("images/gallery/$album");
foreach ($dir as $fileInfo)
{
    if($fileInfo->isDot()) continue;
    $pic = $fileInfo->getFilename();
    print "<div>
            <img src='images/gallery/$album/$pic'>
            </div>";
}

Jquery/ajax:

function albumChosen(id)
{
var id = id;
var album = $('a[id="'+id+'"]').attr("rel");
$.ajax({
    url: "PHPscripts/getAlbums.php",
    type: "POST",
    data: {'album' : album},
    success: function(data){
        $('#galleryList').html(data);
    }
});
return false;

}

If I alert(album); it displays ‘album1’ correctly. So it has something to do with how its reading it from the $_POST

EDIT:
I added the code suggested..

$album = $_POST['album'];
print_r($_POST);
var_dump($album);
$dir = new DirectoryIterator("images/gallery/$album");
//rest of code...

print_r($_POST) prints out Array ( [album] => album1 )
var_dump($album) prints out string 'album1' (length=6)

Answer 1

Turns out I just needed to add ../ to the front of my path.. If it didn’t duplicate the path the way it did I may have figured this out sooner, but because of that I didn’t think there was anything wrong with the path. So here is the complete code that works, again all I added was the ../ in front of the path.

$album = $_POST['album'];
$dir = new DirectoryIterator("../images/gallery/$album");
foreach ($dir as $fileInfo)
{
    if($fileInfo->isDot()) continue;
    $pic = $fileInfo->getFilename();

    print "<div>
                <img src='images/gallery/$album/$pic'>
            </div>";
}
