Hi!

Can you please give an example of such Query Builder usage that would trigger this error?

[motoroller1983]

Sure:

SELECT * FROM table ORDER BY id = 7 DESC

No, I mean how do you use the framework's code. If you could show your example by using QB's methods, would be really great.

[motoroller1983]

$BGs = $this->db->order_by("id = {$this->session->userdata['Background']['id']} DESC", NULL, FALSE)->get('table')->result_array();

In my project that I updated to PHP8.1, I had to check isset($var) before running various native PHP methods like htmlspecialchars($var). You could try it with trim($var): if (isset($var)){trim($var)} https://php.watch/versions/8.1/internal-func-non-nullable-null-deprecation

can you try this function save(){ $id = $this->input->post('id'); $this->form_validation->set_rules('nama_kantin','nama_kantin','required|min_length[5]'); $this->form_validation->set_rules('telpon','telpon','required'); $this->data = [ 'nama_kantin' => $this->input->post('nama_kantin')??'', 'telpon' => $this->input->post('telpon'), ]; if($this->form_validation->run() == FALSE){ $this->load->view('kantin/form',$this->data); }else{ if($id == ''){ $this->makanan->insert($this->data); }else{ $this->makanan->update($id,$this->data); } redirect(base_url('kantin')); } }

I don't understand what's with the latest comments added to this issue (or even if they are related), but regarding the initial report, you are not supposed to send the NULL value for the $direction parameter.
