newbie CodeIgniter toute aide sera appréciée :)

Answer 1

essayer

public function update($where, $data){ 
    $this->db->where($where); 
    $this->db->set($data); //array of new data 
    $this->db->update($this->table); 
    return $this->db->affected_rows(); 
} 

Answer 2

S'il vous plaît imprimer votre requête après la déclaration de mise à jour, cela vous aider à savoir si votre requête est correcte ou non.

$this->db->last_query(); 

Answer 3

S'il vous plaît vérifier que la requête dans le modèle

Controller:

$update_id = array(); 
$update_id['id'] = $this->input->post('id'); 
$data = array(
       'id' => $this->input->post('id'), 
       'dateReserved' => $this->input->post('dateReserved'), 
       'requestedBy' => $this->input->post('requestedBy'), 
       'facility' => $this->input->post('facility'), 
       'dateFrom' => $this->input->post('dateFrom'), 
       'dateTo' => $this->input->post('dateTo'), 
       'timeStart' => $this->input->post('timeStart'), 
       'timeEnd' => $this->input->post('timeEnd'), 
       'status' => $this->input->post('status'), 
       'items' => $this->input->post('items'), 
       'purpose' => $this->input->post('purpose'), 
      ); 

$result = $this->reservation->update('table_name',$update_id, $data); 

Modèle:

$this->db->where($where); 
$this->db->update($table, $data); 
return $this->db->affected_rows();
