Overview

The temporary directory is used for storing files when a file is uploaded. This directory must be writable by whichever user PHP is running as. If not specified, PHP will use the system's default.

If the directory specified is not writable, PHP falls back to the system default temporary directory. If open_basedir is on, then the system default directory must be allowed for an upload to succeed.

Symptom

I'm getting an upload_tmp_dir error when using PHP. How do I fix this error?

You receive an upload_tmp_dir error when you upload files through PHP.

Solution

This can be done by adding the following line in your php.ini file:

upload_tmp_dir /tmp

Alternatively, if you wish to specify upload_tmp_dir for just one domain, add the following line in the domain's vhost.conf file.

<Directory /path/to/vhosts/example.com/httpdocs>
php_admin_value upload_tmp_dir /tmp
</Directory>

Once the changes have been made to the file, run the command below to make the changes take affect:

websrvmng -a -v
