I met an issue using a drupal CMS. I received an error "warning: move_uploaded_file() [function.move-uploaded-file]: Unable to access in /home/.sites/38/site52/web/includes/ on line 572."

I have several web environement, one for coding the website (with IIS 6 and PHP 5.2.3), on for production (with Linux, Apache 2.0 and PHP 5.2.10).

I have no issue on my development server with IIS (same files, same database).

when I run the following line of code :

var_dump( realpath( dirname( __FILE__ ) ) );

Under IIS: string(44) "D:\inetpub\vhosts\dev.*******.com\httpdocs" 

Under Apache: bool(false)

Did I miss something ? 

Best regards,


Test script:
var_dump( realpath( dirname( __FILE__ ) ) );

Expected result:
I wish that this function gives me the real path to let drupal copy some files from the administration.

__FILE__ is already an absolute path, I don't see why you would do that in the 1st place.

However, if you can reproduce the realpath problem with other paths as well, then I suspect a bug on your linux version. Can you try with 5.2.13 pls?

__FILE__ is just a test, the actuel drupal core use realpath on dynamic paths and it always return false.

The actual production environment is an external one so I'm not able to change the php version.

I will ask for it and update this report when it will be done (only if it could be done, unfortunately)

Thanks for your help.

You can test locally as well, or in a VM using the same linux version that you have on your prod server.

the php version is now up to date (5.2.13) and still have the problem.

I tried many realpath(), the absloute path of the web directory ios the following one : /home/.sites/38/site52/web

I thought that realpath( '/home/.sites/38/site52/web' ) should works fine, but it return me false, like any other realpath I'm asking (like realpath( '/' ) which is working well on my IIS environment).

I also tried to set the include path with this line : set_include_path(get_include_path() . PATH_SEPARATOR . '/home/.sites/38/site52/web');
But it still not working fine.

Is there anything I missed ? I'm probably wrong but I don't see where.

Thanks for your help.
