Deleting Files

Hi

I have made a image host script i want to make a admincp now so in the admincp i need help i want to know how i can do this:

List all images in the directory (in a 250 * 200 box or something in a list)
Then at the side of the images put a link so i can delte a image, i know it would use unlink or something but i can't figure out how to do it, iv got this so far;

PHP Code:
<?
$read = '../DirPathNameHere/';    
$myDirectory = opendir($read);    
   while($entryName = readdir($myDirectory))
   {
      if (strtolower(substr($entryName, -3)) == "jpg")
      {
         $dirArray[]=$entryName;
         echo $entryName.'<br />';

         echo '<TABLE width=500 align=center BGCOLOR=#CCCCCC>';
            echo '<TR><TD align=center valign=center>';
               echo '<img src=' .$read.$entryName. '><BR>';
????: NamePros.com http://www.namepros.com/programming/212643-deleting-files.html
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
            echo '</TD></TR>';
         echo '</TABLE>';
       }
   }
   closedir($myDirectory);
?>
And also i had this from sitepoint but did not understand any one: http://www.sitepoint.com/forums/showthread.php?t=367792


Thanks.

something like the following should be ok:-

PHP Code:
<?
$read = '../DirPathNameHere/';
if (isset($_GET['delete']) && !empty($_GET['delete']) && is_file($read.$_GET['delete']) && ereg("^[[:alnum:]]+$",$_GET['delete']))
{
    unlink($read.$_GET['delete']);
}    
$myDirectory = opendir($read);    
   while($entryName = readdir($myDirectory))
   {
      if (strtolower(substr($entryName, -3)) == "jpg")
      {
         $dirArray[]=$entryName;
         echo $entryName.'<br />';
????: NamePros.com http://www.namepros.com/showthread.php?t=212643

         echo '<TABLE width=500 align=center BGCOLOR=#CCCCCC>';
            echo '<TR><TD align=center valign=center>';
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
               echo '<img src=' .$read.$entryName. '><BR></TD>';
            echo '<TR><TD align=center valign=center><a hregf="'.$_SERVER['PHP_SELF'].'?delete'.$entryName.'">Delete image</a></TD></TR>';
         echo '</TABLE>';
       }
   }
   closedir($myDirectory);
?>
I have not checked the script but it shows you basically what needs to be done. Also just a note it would be better if $read was an absolute server path to the necessary folder instead of relatie to the current location.

wackyjoe there is no reason to open the directory like you do to delete a file.

have you tried changing $read to a absolute path instead of a relative path.

Also try putting the following line at the top of the file (after the <?php):-

PHP Code:
error_reporting(E_ALL ^ E_NOTICE); 
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
And let me know if you receive any error.

were you getting a blank screen before you made these changes?

Nothing about these changes should cause no output, can you double check by looking at the source when you go to the page.

Edited a bit.

I tried this and I know it works:
PHP Code:
<?php

$read = 'images/';


if (!empty($_GET['delete']) AND file_exists($read . $_GET['delete']))
{
    if (unlink($read . $_GET['delete']))
    {
        echo 'File deleted.<br /><br />';
    }
    else
    {
        echo 'File could not be deleted.<br /><br />';
    }
}

if ($myDirectory = opendir($read))
{
    while (false !== ($entryName = readdir($myDirectory)))
    {
        if (strtolower(substr($entryName, -3)) == "jpg" OR strtolower(substr($entryName, -3)) == 'gif')
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
        {
            $dirArray[] = $entryName;
            echo $entryName . '<br />';
            echo '<TABLE width=500 align=center BGCOLOR=#CCCCCC>';
            echo '<TR><TD align=center valign=center>';
            echo '<img src=' . $read . $entryName . '><BR></TD>';
            echo '<TR><TD align=center valign=center><a href="' . $_SERVER['PHP_SELF'] . '?delete=' . $entryName . '">Delete image</a></TD></TR>';
            echo '</TABLE>';
        }
    }
    closedir($myDirectory);
}

?>

SV still getting a blank page, here i found another script that dont give me a blank page,

PHP Code:
<?

function deldir($dir) {
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
    $dh=opendir($dir);
        while ($file=readdir($dh)) {
            if($file!="." && $file!="..") {
            $fullpath=$dir."/".$file;
            if(!is_dir($fullpath)) {
                unlink($fullpath);
            } else {
                deldir($fullpath);
            }
        }
    }
    closedir($dh);
    
    if(rmdir($dir)) {
        return true;
    } else {
        return false;
    }
}

if(!empty($_POST['delete'])) {
    foreach($_POST['delete'] as $todel) {
????: NamePros.com http://www.namepros.com/showthread.php?t=212643
        echo 'Deleting File: '.$todel.'<br />';
        deldir($todel); // Function call to deldir.
    }
    echo '<br />';
}
//change the below to the full path to the folder
//requires the trailing /
$folderpath = '/home/networkt/public_html/imgscript/';
$filelist = glob($folderpath.'*');
if(!is_readable($folderpath)){
  die('Invalid folderpath: '.$folderpath);
} 

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

if(empty($filelist)) {
    echo 'No files found.<br />';
    } else {
        foreach($filelist as $file){
        echo $file.'&nbsp;<input type="checkbox" name="delete[]" value="'.$file.'" /><br />'."\n";
    }
}

?>

<input type="submit" name="submit" value="submit" />
</form>
I get this error when trying to delte something: Warning: rmdir(/home/networkt/public_html/imgscript/view): Permission denied in /home/networkt/public_html/imgscript/admincp.php on line 17

I set the files/folder to 777
