The $type value, in this case, can be anything and you’d get much the same result. The only values actually being checked for at this level are ‘direct’ or ‘ftpext’ (for ssl FTP connections, the ftpext method is required). All the other methods require special setup in the wp-config.php file. So specifying ‘ftp’ here is just for convenience, so it won’t use ‘direct’.

Otto,
in your example you’re forcing an ftp method. I couldn’t find that one in the code.
It seems the valid methods are ‘ftpext’, ‘ftpsockets’ and ‘ssh2′

Hi Otto, what would be the most secure way to deal with a caching solution? I noticed Total Cache for example writes files directly (no wp file api), I think another caching plugin stores the user credentials (if required) in the database and another article mentions storing credentials in wp-config.php as constants. I’m not sure the latter are that much more secure because if a the credentials are compromised a hacker would have free range.

Is it possible to upload files outside the WordPress root directory by using the WP_Filesystem?

Look at where I call request_filesystem_credentials. If the result of that call is anything other than false, then you either don’t need credentials, or already have the necessary credentials. In which case, you continue on as per usual.

However, if that does return false, or if the WP_Filesystem($creds) call fails, then you don’t have the proper credentials yet, and you must therefore get them from the user somehow, in which case you have to show them some kind of form.

Do you have any examples of how to write a file using the WP_Filesystem API that does not require a form submission?

If you’re getting an error from the put_contents() call, then you may want to store the error in a variable (it’ll probably be a WP_Error object) and var_dump it to see what sort of error it is that you’re getting.
