[ PATCH ] – Undefined index post_type in wiki/wiki.php L1816

Using this plugin on a task, came across this little gem:

function name_save($post_name) {
	if ($_POST['post_type'] == 'incsub_wiki' && empty($post_name)) {
		$post_name = $_POST['post_title'];
	}

	return $post_name;
}

Needs to check if both array keys are set first, before assuming they are, like so:

function name_save($post_name) {
	if ( isset( $_POST['post_type'] ) && $_POST['post_type'] == 'incsub_wiki' && empty($post_name)) {
		if ( ! isset( $_POST['post_title'] ) ) {
			return $post_name;
		}
		$post_name = $_POST['post_title'];
	}

	return $post_name;
}

Please fix this, my debug.log is getting flooded during a WP-CLI import…
