Create a folder if it doesn't already exist

Question

I've run into a few cases with wordpress installs with bluehost where I've encountered errors with my wordpress theme because the uploads folder (wp-content/uploads) was not present.

Apparently the bluehost cpanel WP installer does not create this folder, though HostGator does.

So I need to add code to my theme that checks for the folder and creates it otherwise.

Answer 1

Try this:

if (!is_dir('path/to/directory')) {
    mkdir('path/to/directory');
}

Answer 2

What about a helper function like this:

function makeDir($path)
{
   $ret = mkdir($path); // use @mkdir if you want to suppress warnings/errors
   return $ret === true || is_dir($path);
}

It will return true if the directory was successfully created or already exists, and false if the directory couldn't be created.

Another alternative is:

function makeDir($path)
{
   return is_dir($path) || mkdir($path);
}
