Hi all, I am very fortunate to slove a drupal problem for you concerning the drupal open_base restriction problem, I will speak english to tell you that three points.

Firstly, I will show you the problem on vitual host site tmp/ error.

warning: open_basedir restriction in effect.

Error with file api and open_basedir restriction

warning: realpath() [function.realpath]: open_basedir restriction in effect. File(/var/tmp) is not within the allowed path(s): (/home1/vhost/vh449538:/home1/vhost/vh449538/temp:/tmp/expl:/tmp/check) in /home1/vhost/vh449538/www/drupal/includes/file.inc on line 190.

Second, I have found some discussion on the drupal site. They also have this problem but I think the solution is not great.

• http://drupal.org/node/4410
• http://drupal.org/node/5961
• http://drupal.org/node/5961

I thiink I should not modify the drupal core, Its very complex to upgrade your drupal core and maybe others completely dont know where is the problem.

therefor, We should config our setting File system Tell Drupal where to store uploaded files and how they are accessed.

Perfectly, Administrator  Site configuration the file system

Firstly, the site will alert you the /var/tmp is unavailable and dont has the directory, then please go to the place like below:

Home » Administer » Site configuration

Temporary directory: /var/tmp

A file system path where uploaded files will be stored during previews.

change the value from the absolute path /var/temp  to relative path tmp, but you must confirm your site has the directory and its permission is writeable, chmod is 0777.

Finally, the problem is ok, This is my shared drupal issue. thank you!
