问题
I'm attempting to create a new forum on an existing forum. I can create the new forum quite easily and view it from the admin console. The problem is I need it to show up at the front end as well for users. This is done via permissions.
What I am attempting to do therefore is copy the permissions of the parent forum (which is public) to the forum I create. However the forum still doesn't appear to be showing up on the public facing side.
Here's my code (please note the phpBB include files have been loaded previously):
// $forum_name = name of the new forum
// $parent_id = the forum which this is a child of
function create_forum($forum_name, $parent_id)
{
global $phpbb_root_path, $phpEx, $user, $auth, $cache, $db, $config, $template, $table_prefix;
$response = array();
$data = array(
'forum_name' => $forum_name,
);
// Forum info
$sql = 'SELECT forum_id
FROM ' . FORUMS_TABLE . '
WHERE ' . $db->sql_build_array('SELECT', $data);
$result = $db->sql_query($sql);
$forum_id = (int) $db->sql_fetchfield('forum_id');
$db->sql_freeresult($result);
if ($forum_id)
{
$response['error'] = TRUE;
$response['error_msg'] = 'FORUM_EXISTS';
$response['forum_id'] = $forum_id;
}
else
{
$forum_data = array(
'parent_id' => $parent_id,
