Question

我已经添加，查看，删除记录但我无法更新数据库中的记录。但是当我尝试更新名称时，alamat等在数据库中保持不变。我在下面列出了我的控制器，型号和视图：

模型代码

    function update($id,$siswa)
        {
            $this->db->where($this->primary_key,$id);
            $this->db->update($this->table_name,$siswa);
        }

控制器代码

    function update($id=1)
            {
                $this->_set_fields();
                $siswa = $this->siswa_model->get_by_id($id)->row();
                $this->form_validation->id = $id;
                $this->form_validation->nama = $siswa->nama;
                if (isset($_POST['jenis_kelamin'])) {
                    $_POST['jenis_kelamin'] = strtoupper($data['siswa']['jenis_kelamin']);
                }
                if (isset($_POST['tanggal_lahir'])) {
                    $data['siswa']['tanggal_lahir'] = date('d-m-Y',strtotime($data['siswa']['tanggal_lahir']));
                }

                $data['title'] = 'Update siswa';
                $data['message'] = '';
                $data['action'] = site_url('siswa/updateSiswa');
                $data['link_back']= anchor('siswa/index/','Back to list of siswas',array('class'=>'back'));

                $this->load->view('siswaEdit',$data);
            }

            function updateSiswa()
            {
                //set common properties
                $data['title'] = 'Update siswa';
                $data['action'] = site_url('siswa/updateSiswa');
                $data['link_back']= anchor('siswa/index/','Back to list of siswas',array('class'=>'back'));

                //$this->load->library('form_validation');
                //set validation properties

                    $this->_set_fields();
                    $this->_set_rules();

                    //$data['action']=('siswa/update/'.$id);

                    //run validation
                    if ($this->form_validation->run() === FALSE) {
                        $data['message']='';

                        $data['siswa'] = $this->siswa_model->get_by_id($id)->row_array();
                        if (isset($_POST['jenis_kelamin'])) {
                            $_POST['jenis_kelamin'] = strtoupper($data['siswa']['jenis_kelamin']);
                        }
                        if (isset($_POST['tanggal_lahir'])) {
                            $data['siswa']['tanggal_lahir'] = date('d-m-Y',strtotime($data['siswa']['tanggal_lahir']));
                        }

                        //set common properties
                        $data['title']='Update siswa';
                        $data['message']='';

                    }
                    else
                    {
                        //save data
                        $id = $this->input->post('id');
                        $siswa=array( 'id'=>$id,
                            'nama'=>$this->input->post('nama'),
                            'alamat'=>$this->input->post('alamat'),
                            'jenis_kelamin'=>$this->input->post('jenis_kelamin'),
                            'tanggal_lahir'=>date('Y-m-d', strtotime($this->input->post('tanggal_lahir'))));
                        $this->siswa_model->update($id,$siswa);
                        $data['siswa'] = $this->siswa_model->get_by_id($id)->row_array();

                        //set user message;
                        $data['message']='update siswa success';
                    }
                    $data['link_back']= anchor('siswa/index/','Lihat Daftar Siswa',array('class'=>'back'));

                    //load view
                    $this->load->view('siswaEdit',$data);
            }

你能帮助我从我的程序中找到解决问题的方法吗？

我认为您在上面显示的视图页面，它只列出了记录。您可以在表单中列出以提交数据。

在CodeIgniter中更新记录数据库
