Beginner Question: opendir

[toddheasley]

I have a script that displays all images in a directory. It only works if the script is placed in the same directory as the images. I would like place the script elsewhere (outside the directory) and specify a path to the directory containing the images. Example: droningon.com/furniture/

How do I change the sript from reading the CWD to a path that I specify?

[cgraz]

just specify the path

$handle = opendir('../images/trucks/')

This example would be back a directory in the images folder, then the trucks folder within that images folder.

Thanks for the suggestion.

I put the script outside the directory containing images. I changed "$handle = opendir( getcwd() )" to "$handle = opendir("images/")." It didn't give me any warnings, but it's not finding the images in the directory. It's returning an empty array (I think). Is there a problem elsewhere in the PHP, maybe?

<?php

$filetypes = array("jpg","jpeg","gif","png");
$filelist = array();
$handle = opendir("images/");

while ( false != ( $file = readdir($handle) ) ) {

if (is_file($file) && $file != "." && $file != "..") {

    $extention = explode(".",$file);
    $extfield = count($extention)-1;
    $extention = $extention[$extfield];

    if( in_array($extention,$filetypes) ) {

        array_push ($filelist,$file);
    }
}

}

$files = array_reverse ($filelist);
foreach ( $files as $file ) {

?>
<a name="<?= $file ?>" href="#<?= $file ?>"><img src="<?= $file ?>" alt="<?= $file ?>"></a>
<?php

}

?>

try just printing the directory first, then if that works, move your way up to printing just the image files.

It prints the directory correctly. I'm not exactly sure where to go from here, but I should be able to get it. If I run into any further trouble, I may bother you again, but thanks so much.

try something like this

<?

   if ($handle = opendir('images/')) {

    while (false !== ($file = readdir($handle))) { 

       if ($file != "." && $file != "..") { 
          $extension = strrchr($file, ".jpg");

          if ($extension == strtolower(".jpg")) {
              echo $file . "<br>";
          }

       }

     }

}

closedir($handle); 

?>

Edit: Just realized you wanted all image files, not just .jpg, but you can play with the code to get it to work the way you want.
