Edit Multiple Files on Single Page

[Mr__Fusion]

I volunteer for a non-profit student club con campus, and the photo gallery script we use, MiniGal, allows the admin to comments images. However, the gallery script creates a separate ".cmt" file for each commented image containing the plain text of the caption.

What I want to do is echo a directory listing of image files, then have a textbox to the right of each image filename (for each corresponding comment file) to edit the caption text of each image. At the end of the page, there would be a submit button to save all of the files listed at once (or in a batch operation, whatever works, I'm new at this). The page might render something like this:

[FONT=arial]IMG_1003.jpg[/FONT][FONT=courier new] | [Our new dog.__________]
[/FONT][FONT=arial]IMG_1004.jpg[/FONT][FONT=courier new] | [Heel, Rover._______]
[/FONT][FONT=arial]IMG_1008.jpg[/FONT][FONT=courier new] | [No, we don't eat socks.]
[/FONT][FONT=arial]IMG_1009.jpg[/FONT][FONT=courier new] | [Not shoelaces, either.]
[/FONT][FONT=arial]IMG_1015.jpg[/FONT][FONT=courier new] | [Good boy.___________]
[/FONT][FONT=arial]IMG_1008.jpg[/FONT][FONT=courier new] | ["Oh joy, belly rub!"__]

[[/FONT][FONT=arial] Submit [/FONT][FONT=courier new]] [/FONT]

It seems like there 'should' be an easy way to do this akin to a multiple file upload widget, but I haven't found any useful snippets to get me started. Plus, I'm still new at coding for PHP; I can edit scripts really well, but when I start from scratch, it gets so convoluted that I can't debug my own work. Oy.

Is there anyone who can point me in the right direction (or even perhaps send me a complete script to modify to my heart's content?) Thanks in advance!

i'm going to assume 2 things: the .cmt files are just plain text files and are named the same as the .jpg files. if so here is a very ruff (and untested) idea:

<?
$path = '/path/to/images/';

if (!isset($_POST['submit']))
{
	$handle = opendir($path);
	while (($filename = readdir($handle)) !== false)
	{
		if ($filename != '.' && $filename != '..')
		{
			$pathinfo = pathinfo($filename);
			if ($pathinfo['extension'] == 'jpg')
			{
				$filename_no_ext = basename($filename);
				if (file_exits($path . $filename_no_ext . '.cmt'))
				{
					$comment = file_get_contents($path . $filename_no_ext . '.cmt');
				}
				else
				{
					$comment = '';
				}
				$file_array[$filename] = $comment;
			}
		}
	}

ksort($file_array);

echo '<form action="" method="POST">';

foreach ($file_array as $key => $value)
{
	echo $key . ' <input type="text" name="images[' . $key . ']" value="' . $value . '"><br>';
}

echo '
<input type="submit" name="submit" value="submit">
</form>
';
}
else
{
	foreach ($_POST['images'] as $key => $value)
	{
		$value = trim($value);
		$value = stripslahes($value);

	$filename_no_ext = basename($key);

	$handle = fopen($path . $filename_no_ext . '.cmt', 'w');
	$fwrite = fwrite($handle, $value);
	if ($fwrite) {echo 'comment for ' . $key . ' successfully written<br>';}
	fclose($handle);		
}
}
?>

Ah-ha! You are awesome. When I finish tweaking it, I'll post the final code for anyone else interested.

It's a bit rough as to the HTML, but this is basically what I'll be working off of. Thanks again!
