On a grid, I have a label that grabs the names of the image thumbnails
in the folder, the shows them as images. However, I also want to grab
the name of only the first non-thumbnail file by itself before the rest.
The first two files are . and .. rather than image names so I am not
sure how to do it without getting the rest. All I am able to get is the
dot when using:
$handle2 = opendir($directory."/Large");
$FirstFile = readdir($handle2);
Can anyone help? Thanks.

You just keep repeating the readdir() in a loop and it returns the next file
until there are no more files found.

Thanks, Don. Since I have been using CodeCharge Studio almost
exclusively for years, it has me so spoiled that I am not even sure
how to create manual loops anymore. I know how to get all the files
but I am unsure if how to get only the one I want, which is the first
one after the two dot files. Can you show me some code? Thanks again.

while ($FirstFile = readdir($handle2)) {
if (($FirstFile != '..') && ($FirstFile != '.')); break;
}

Thanks Don, but I seem to be missing something here as it is still
giving only the dot instead of a file name. Also, rather than saying
what not to get, how can I make it get only jpg, gif and png files? That
would be more direct and to the point in case the folder contains
anything else. I am doing that already with the thumbnails but I can't
figure out how to apply it here.
This is what I have for the thumbnails:
while (false !== ($file = readdir($handle))) {
$pieces = explode(".", $file);
$FileType = $pieces[count($pieces) -1];
if ($FileType == "jpg" || $FileType == "gif" || $FileType == "png") {
$output[] = '<img src="'.$directory.'/Reduced/'.$file.'">';
}
}
This was created as part of a function, the many HTML lines of which are
output to a label using
return join("\n",$output);

This did the trick:
while ($FirstFile = readdir($handle2)) {
$pieces2 = explode(".", $FirstFile);
$FileTypeLarge = $pieces2[count($pieces2) -1];
if ($FileTypeLarge == "jpg" || $FileTypeLarge == "gif" ||
$FileTypeLarge == "png") {
break;
}
}
