PHP mkdir() Invalid Path

Question

I'm trying to save files on my server, and as a prerequisite, create directories that don't exist.

I am running a script, dl.php, at /home/public_html/www3/scripts/dl.php:

$request['savedir'] = '/home/public_html/www3/scripts/images/logs';
if( !is_dir($request['savedir']) )
    mkdir($request['savedir']);

And I get:

Warning: mkdir(): Invalid path in /home/public_html/www3/scripts/dl.php

The "images" does exist.

are you running the script via another php script called in a browser (basically by Apache) or on the server command line as root or another user? – Hulsey

I'm running the script directly at the moment, but in production it will be run by a a jQuery Ajax post call. – Distemper

Wait , didn't read that completely. it's being called by the browser directly, sorry – Distemper

I just forgot to type it here, it's there on the script, just checked. – Distemper

I am assuming missing $ is just a typo since the error doesn't complain about it but I am more thinking about user privileges on the folders. Those must be "apache" group and user to be written by Apache (meaning when it works as web application via browser). – Hulsey

@Mat the images folder does exist. It shouldn't need to be recursive. – Distemper

Did you check your "images" folder user and group and permissions? They are all ok? – Hulsey

@Hulsey Just did, turns out in creation of the folder, it had wrong permissions. I changed them to 700, and it's working. Thanks! Please make this an answer. – Distemper

Glad to hear it helps. – Hulsey

Answer 1

Please check your "images" folder owner and permissions. It requires to be write enabled to be used with "apache" user/group when it is executed in browser. The error is actually about "permissions" since it is not visible to "apache" user.

Answer 2

1. Open the config.php on application/config folder
2. Browse all the way down to the $config['sess_save_path'] = NULL; line.
3. Change the NULL value to BASEPATH.'sessions'
