mkdir() says theres no such directory and fails?

Question

Im likely doing something very simply wrong, but when I try to make a directory (using a variable of an insert just performed as the last folder name), I get the error:

Answer 1

It happens because you don't have images/listing-images/rent path existing in your filesystem.

If you want to create the whole path - just pass the 3rd argument as a true:

mkdir('images/listing-images/rent/'.$insertID, 0777, true);

There is also a chance you're in a wrong directory currently. If this is the case - you need to change the current dir with chdir() or specify the full path.
