[RESOLVED] Deleting files from a directory

[mpar612]

I am using PHP to retrieve a list of files from a directory with a checkbox next to each of them. When the user puts a check in one or more of the checkboxes and clicks a submit button on the form, I want the files with a check in the box to be deleted from the directory.

My logic behind getting this to work is wrong somewhere. I'm not really sure where it is. Does anyone have ideas? Any and all help would be greatly appreciated. Thanks!

Here is the code (that I found somewhere online) that lists the files in the specified directroy and puts a checkbox next to each file. This works well in displaying the directory contents on the screen:

[code=php]$audio_upc = $_GET['upc'];

//define the path as relative
$path = "../Lounge/audio/$audio_upc";

    //using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

//running the while loop
while ($file = readdir($dir_handle)) 
     {
	if($file!="." && $file!="..")
   	echo "<input type=\"checkbox\" name=\"delete\" value=\"$file\">$file<br>";
	}

//closing the directory
closedir($dir_handle);
print "</td></tr>";[/code]

This is the code that I am currently using to delete the file(s) from the directory, but it is not working. When the code executes I don't get any errors or anything, but the files are not deleted from the directory and the "print $path;" and "print $file;" do not return anything. Maybe my whole problem is a variable scope issue??? I'm not sure.

 [code=php]$audio_dir_new = $_POST[upc];
global $path;
global $file;
print $path;
 print $file;
 if ($_POST['delete'] == '$file') {
 $delete_audio = "$path/$file";
 unlink($delete_audio);
 }[/code]

Not sure what your issue is, but I modified the code above to work stand-alone. What I came up with works for me. Gives me feedback as to what file was deleted, and which files failed.

Works like a charm if you set the paths right:

<?php
//define the path as relative
$path = "./delMult/images/originals";

if( isset($_POST) && !empty($_POST['delete']))
{
	$files = $_POST['delete'];

foreach($files AS $file)
{
	if(unlink($path.'/'.$file))
		echo '<div style="border: 1px solid #000; background-color: #70db93; padding: 5px;">Successfully deleted file <em>', $path, '/', $file, '</div>';
	else
		echo '<div style="border: 1px solid #000; background-color: #ff6a6a; padding: 5px;">Failed to delete file <em>', $path, '/', $file, '</div>';
}
}
else
{
	echo '<div style="border: 1px solid #000; background-color: #b4cdcd; padding: 5px;">No files set for deletion.</div>';
}

echo '<hr>';
echo '<form action="', $_SERVER['PHP_SELF'], '" method="post">';
// List all files in directory w/ checkbox for deletion:

//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

//running the while loop
while ($file = readdir($dir_handle))
	 {
	if($file!="." && $file!="..")
		// Modified so it's an array for multiple selections
	   echo "<input type=\"checkbox\" name=\"delete[]\" value=\"$file\">$file<br>";
	}

//closing the directory
closedir($dir_handle);
echo '<input type="submit" name="submit" value="Delete Selected File(s)">
</form>';
?>

Thanks for your code! It didn't work because of the way I had other parts of my page coded, but after some slight modifications. It worked great. Thank you so much for your help!!!
