Sounds like you dont have the right file permissions set.

You need to chmod the directory to a more appropriate level!
[php]
<?php
chmod("/directory/to/chmod", 0755);
?>
[/php]

Lemme know if this helps!

Also! Remember to wrap your php code in the CODE tags.

IT helps people look through your code :)

Hi.

Please use [code] tags when posting your code examples. (See How to ask a question)

[code=php] ...PHP code goes here... [/code]

Thank you.

      <?php

      chmod("/directory/to/chmod", 0755);

        ?>

please tell me what else to do..

How exactly did the path you use look?

If you want to use a relative path, a path relative to the current directory, there should not be a / in front of it.

On the other hand, if you are using an absolute path, a path relative to the root directory, you should put a / in front of it.

Like:

Expand|Select|Wrap|Line Numbers

 
# An absolute path

chmod("/var/www/html/images/image.jpg", 0755);
 
# A relative path, assuming the current directory is /var/www/html

chmod("images/image.jpg", 0755);

It's not the image he's wanting to chmod() is it?

Am i right in thinking he would also need to chmod the php file that is executing? i.e. the uploader script aswell as the actual directory where the images would be stored? Or is that not necessary?

It doesn't really matter whether it is a file or a directory. All directories in a Linux system are essentially files anyways so the chmod command works the same on both.

He would not have to chmod the PHP file that is being executed, only the file or directory he intends to change.

The user running the HTTP server only needs read and execute permission on the PHP file to be able to execute it, but it needs write permission on the file the PHP script is meant to change.
