Hi I am trying to store in a table multiple values in one time, my table have three columns

1.categoriaslocatariosID
2.localID
3.categoriaID

and I tried this

Code:

$categorias = array(
        'telefonia'                      =>    $this->input->post('telefonia'),
        'computo'                    =>    $this->input->post('computo'),
        'fotografia'                =>    $this->input->post('fotografia'),
        'electronica'                =>    $this->input->post('electronica'),
        'instrumentos_musicales'    =>    $this->input->post('instrumentos_musicales'),
        'entretenimiento'            =>    $this->input->post('entretenimiento'),
        'reparacion'                =>    $this->input->post('reparacion'),
        );
        
        $id = array(
        'localID'                    =>    $this->input->post('localID'),
        );
        
        foreach ($categorias as $user):
        $data = array(
               'localID' => $id,
               'categoriaID' => $user
            );

        $this->db->insert('categoriasLocatarios', $data);
        endforeach;
        
        redirect('clientes_corporativos');

but it is sending me an error
