Permission Denied - PHP Unlink

permission denied - php unlink

You (as in the process that runs b.php, either you through CLI or a webserver) need write access to the directory in which the files are located. You are updating the directory content, so access to the file is not enough.

Note that if you use the PHP chmod() function to set the mode of a file or folder to 777 you should use 0777 to make sure the number is correctly interpreted as an octal number.

Unlink file permission denied

Are you completely sure the old code is still working?

"Permission denied" might simply mean your current server user (i.e. Apache / www-data) has no permissions to delete the file.

You should check the file's permissions, and that your server has actually permissions to manipulate the file.

Unlink - Permission denied. How to resolve?

What does $POST['file'] is holding? If it is an array then check for blanks / null values as well. file_exists() will return true in case of $file is blank, but then your path will end up with uploads/487001/ and you will get that warning.

How to get permission to use unlink()?

Permission denied error happens because you're trying to delete a file without having enough/right permissions for doing that.

To do this you must be using superuser account or be the same user that have uploaded the file.

You can go to the directory from your command line and check the permissions that are set to the file.

The easiest solution is to loggin as administrator/root and delete the file.

Here is another work around:

// define if we under Windows
$tmp = dirname(__FILE__);
if (strpos($tmp, '/', 0)!==false) {
  define('WINDOWS_SERVER', false);
  } else {
  define('WINDOWS_SERVER', true);
}
  $deleteError = 0;
  if (!WINDOWS_SERVER) {
    if (!unlink($fileName)) {
      $deleteError = 1;
    }
  } else {
    $lines = array();
    exec("DEL /F/Q \"$fileName\"", $lines, $deleteError);
  }
  if ($deleteError) {
    echo 'file delete error';
  }

And some more: PHP Manual, unlink(), Post 106952

I would recommend, always first to check PHP Manual (in case your question concerns PHP), just go to the page with function that you have problems with and just click search CTRL+F in your browser and enter, for example, Windows, and as a result, in your case, you would find at least 7 related posts to that or very close to that what you were looking for.

Warning: unlink($name): Permission denied

The problem is that if there is no user image, your $path-variable will just contain the path to the folder, which you then are trying to unlink.

Just check if the file exists before unlinking:

$deleteLink = $deleteImg['user_img'];
$path = "user/profilepic/$deleteLink";

if (is_file($path)) {
    // The path exists and is a file
    unlink($path);    
}

This won't work with file_exists() though since that function returns true even if the path is a folder. Since $path will just contain a folder if the user doesn't have an image name in the DB, you would end up with the exact same problem as before.

is_file() will check if the path exists and if it is a file.

Permission Denied when trying to delete image using unlink in codeigniter

First of all give that folder a permission of 0777 and use the fullpath with unlink like this:

`unlink(FCPATH."gambar".DIRECTORY_SEPARATOR."hasil".DIRECTORY_SEPARATOR."data_trainingtanpakotak".DIRECTORY_SEPARATOR.$group_picture);`

I've used FCPATH here supposingly that the dir you are deleting from is in your FCPATH
