h1. Problems uploading images or files [todo]
In order to use the Textpattern administration interface to upload images and files (via content > images or content > files), you’ll need to ensure Textpattern has access to the necessary directories.
Both image and file uploads require write access to a temporary directory. Textpattern attempts to find a writable temp directory during installation, and will automatically use it if one is found.
If no writable temporary directory was found, Textpattern will display a warning message on your admin > diagnostics page.
If you’ve recently moved Textpattern to a new server, you might need to alter the temporary directory setting to point to a new location.
To force Textpattern to search for a new temporary directory:
Go to admin > preferences > advanced preferences
Find the “Temp folder” setting, under “Admin”
Delete the contents of the Temp folder setting, and click the Save button.
If Textpattern is able to find a suitable temporary directory, it will automatically fill in the new setting. If the Temp folder setting stays blank, you’ll need to set it manually:
On the admin > diagnostics page, make a note of the Textpattern path setting. Typically it looks something like @/home/foo/public_html/textpattern@.
On your web server, using an FTP client, shell access or a file manager provided by your hosting company, find the @tmp@ folder located inside the Textpattern path directory.
Change the permissions on this @tmp@ folder to make it writable by the web server process. Your hosting company may provide specific instructions on this. On a Unix server, you may have to make the directory “world writable” by setting its permissions to @777@, but before you do this, always consult your webhost, because @777@ permissions are a serious security risk on shared webhosts and frowned upon in other hosting setups, so it’s safer to first try @700@ or (if that fails) @711@ or @755@ permissions.
On the admin > preferences > advanced page, change the Temp folder setting to the full path to this tmp folder. If your Textpattern path is @/home/foo/public_html/textpattern@, that means your Temp folder setting should be @/home/foo/public_html/textpattern/tmp@.
Regardless of whether the temp directory is detected automatically or set manually, you’ll also need to make the @files@ and @images@ directories writable. These are located in the same parent directory that contains your Textpattern path - using the above example, @/home/foo/public_html/images@ and @/home/foo/public_html/files@.
Using the same method described in Step 2 above, change the permissions on both of these directories to make them writable by the web server process.
Once the Temp folder is set correctly and writable, and the images and files folders are writable, file and image uploads should work correctly.
