Failed to Open Stream: Permission Denied

Hi All,

I can’t seem to get the following code to work with a WordPress template. When I try to upload an avatar, I receive the following error:


Warning: copy(/admin.png) [function.copy]: failed to open stream: Permission denied in /home/user-name/domains/my-domain.com/public_html/wp-content/themes/adWhiteBullet/template-authoradmin.php on line 299 

I will add the number 299 in front of the appropriate line below. By any chance, does anyone see my goofheaded problem?

Thank you in advance!

Is the upload folder writable?

If I’m reading the code correctly, is /images/thumbs off the root directory? Or is it the root directory?

For both of those folders, I chmod-ed them to 777. Unfortunately, the error persisted.

Perhaps it’s writing to a different folder (and I’m not reading the code right)?

A friend said it might be a javascript error? Personally, I didn’t see where that would come into play…

Thanks again,

Ansel

The script gets the path through: get_option(‘upload_path’)
To know the value, just echo it.
If it starts with ‘/’, it means it starts from the root folder.

Oop! It turned out to be a WordPress configuration error. I needed to add the upload directory to the Miscellaneous section of the Settings. I am sorry for wasting anyone’s time!

Thank you for the post, Guido. :slight_smile:
