I wonder whether someone may be able to help me please.
I've put together the script below which creates an image gallery.
<?php
if (isset($_POST['del']))
$originalname = intval($_POST['del']);
$file = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/' '$originalname';
if (!unlink($file))
{
echo ("Error deleting $file");
}
else
{
echo ("Deleted $file");
}
?>
<?php
$galleryPath = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/';
$thumbnailsPath = $galleryPath . 'Thumbnails/';
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;
$descriptions = new DOMDocument('1.0');
$descriptions->load($absGalleryPath . 'files.xml');
?>

Against each image, and appearing in this line of my code: alt="<?php echo $name; ?>" src="<?php echo $thumbnail; ?>" /></a><?php echo "<input type='radio' name='del' value='{$originalname}' />"?></li> I've added a radio button.
Upon a radio button being selected, and the 'Delete Selected Image' button being clicked I would like the image to be deleted at this filepath:
$galleryPath = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/';
and here : $thumbnailsPath = $galleryPath . 'Thumbnails/';
I'm not brilliant with PHP, but I've done some research and I believe that I need to use the 'unlink' command. So I thought I'd have a go at trying to write this procedure using just the one filepath initially. I can select a radio button, and get the correct Dialog Confirmation message to appear, but unfortunately it doesn't delete the image, and I'm not really sure where the problem lies.
I just wondered whether someone could perhaps t ake a look at this please and let me know where I've gone wrong?
Many thanks and regards
If you know you are passing the correct path to the image to the unlink command, it is possible the user account running PHP does not have write permissions on the file.
You may want to turn errors on at E_WARNING level, then run a test script to see if you get a warning. You should also test the return value of unlink, as it returns FALSE on failure.
