I cannot reach the title of my forum - velismo - 08-05-2021
I'm trying to create a forum and I have it(more or less) but I cannot reach the title and other elements in the view of the single entrance.
This is the error message that I recieve:

Here you have the model:
PHP Code:
public function create_forum($title, $description) {
$data = array(
'title' => $title,
'slug' => strtolower(url_title($title)),
'description' => $description,
'created_at' => date('Y-m-j H:i:s'),
'updated_at' => date('Y-m-j H:i:s')
);
return $this->db->insert('forums', $data);
}
PHP Code:
public function create_topic($forum_id, $title, $content, $user_id) {
$data = array(
'title' => $title,
'slug' => strtolower(url_title($title)),
'user_id' => $user_id,
'forum_id' => $forum_id,
'created_at' => date('Y-m-j H:i:s'),
'updated_at' => date('Y-m-j H:i:s'),
);
if ($this->db->insert('topics', $data)) {
$topic_id = $this->db->insert_id();
return $this->create_post($topic_id, $user_id, $content);
}
return false;
}
If you miss any other part of the code, just let me know.
Thank you so much for the help.
