PHP SPL RecursiveDirectoryIterator - getPath and ltrim path

Toy_Sun

I need to get a list of jpgs from my images directory and have it's subdirectory names appear as the CSS div class for a given image. I can get this to work, but I can't figure out how to get just the enclosing directory name as the div class without any of the path leading up to it. i.e

path to image is: images2/food/hotdog.jpg
I need: <div class="food"><a href="images2/food/hotdog.jpg">

The below works but doesn't create the array, I only get one image. If I remove my $path and $folder attempt, and have $thelist .= 'getPath().' it works but I get <div class="images2/food"> and my javascript doesn't like that.

Here is my code:

<?php
$it = new RecursiveDirectoryIterator('images2');
$display = Array ( 'jpeg', 'jpg' );
foreach(new RecursiveIteratorIterator($it) as $file)

if ( In_Array ( SubStr ( $file, StrrPos ( $file, '.' ) + 1 ), $display ) == true )

$path = $file->getPath();
$folder = ltrim($path, "/images2");

$thelist .= '<div class="'.$folder.'"><a href="'.$file->getPath().'/'.$file->getFilename().'"rel="shadowbox['.$file->getPath().']">'.'<img src="../slir/w180-h180-c1:1/test/isotope/'.$file->getPath().'/'.$file->getFilename().'" /></a></div>'; 

?>    

<?=$thelist?>

You could maybe do (untested):

$path = '/foo/bar/directory/file.jpg';
$class = basename(dirname($path));

Hi,
I don't think that would work, as the thing is that the path is determined by:

$file->getPath()
I can't hard code the path to do:
$path = '/foo/bar/directory/file.jpg';

and when I try and do:
$path = $file->getPath();

I think that it breaks the iteration of the iterator...

Thanks for the quick reply, though!

That was just an example:

$path = $file->getPath();
$class = basename(dirname($path));

// ...or...

$class = basename(dirname($file->getPath()));

Hi,
The ideas you suggested also break the directory parsing. In other words, I'm only getting one file returned instead of the various files that exist in subdirectories of /images2.

That's the same problem I was having with my attempt. Note that I'm placing your code before my echo statement - I'm pretty green, so I think that may be the problem - syntax?.

But also, your suggested returns the starting directory, /images2 and I want the containing directory of the final .jpg file.
My version gave me that, but then broke the directory parsing - I only get the first file.

Here's what I tried from you (and also tried the other version)


<?php


$it = new RecursiveDirectoryIterator('images2');
$display = Array ( 'jpeg', 'jpg' );
foreach(new RecursiveIteratorIterator($it) as $file)

if ( In_Array ( SubStr ( $file, StrrPos ( $file, '.' ) + 1 ), $display ) == true )

$path = $file->getPath();
$class = basename(dirname($path));

echo  '<div class="'.$class.'"><a href="'.$file->getPath().'/'.$file->getFilename().'"rel="shadowbox['.$file->getPath().']">'.'<img src="../slir/w180-h180-c1:1/test/isotope/'.$file->getPath().'/'.$file->getFilename().'" /></a></div>'; 



?>

Thanks again for your replies, appreciated!
