缺少参数在codeigniter中上传图像编辑数据

Question

我想我已经正确地写这段代码，但我得到一个关于缺少参数的问题，我选择了文件图像上传，但我也得到这样的错误。

 
A PHP Error was encountered 

Severity: Warning 

Message: Missing argument 1 for Data_guru::edit()

You did not select a file to upload. 

谢谢您的回答

我的控制器

public function edit($id) { 
$this->form_validation->set_rules('nama_guru','Nama Guru','required');  
$this->form_validation->set_rules('alamat','Alamat','required'); 

    if ($this->form_validation->run() === FALSE) { 
     $data = array ('title' => 'Edit Data Guru', 
         'detail' => $this->monitoring_model->detail_guru($id), 
         'isi' => 'monitoring/edit_guru_view' 
         ); 
    $this->load->view('monitoring/layout/wrapper',$data); 
    //Kalau Tidak Ada Error Data Guru DiUpdate 
    }else{ 
      $config['file_name']   = $this->input->post('nama_guru'); 
      $config['upload_path']   = './assets/image/guru/'; 
      $config['allowed_types']  = 'gif|jpg|png'; 
      $config['max_size']    = 3000; 
      $config['max_width']   = 3000; 
      $config['max_height']   = 3000; 

      $this->load->library('upload', $config); 

      if (! $this->upload->do_upload('foto_guru')) 
      { 
        echo $this->upload->display_errors(); 
      } 
      else 
      { 
        $gbr = $this->upload->data(); 
        $data = array(
          'foto_guru'  => $gbr['file_name'], 
          'id_guru'  => $this->input->post('id_guru'), 
          'nama_guru'  => $this->input->post('nama_guru'), 
          'jenis_kelamin' => $this->input->post('jen_kel'), 
          'alamat'  => $this->input->post('alamat'), 
          'tempat_lahir' => $this->input->post('tempat_lahir'), 
          'tgl_lahir'  => $this->input->post('tgl_lahir'), 
          'no_hp'   => $this->input->post('no_hp'), 
          'username'  => $this->input->post('username'), 
          'password'  => $this->input->post('password') 
        ); 

     $this->monitoring_model->edit_guru($data); 
     redirect(base_url().'tim_monitoring/data_guru'); 
    } 
} 
} 

我的模型

//Menampilkan Detail Guru Di Halaman Edit Guru 
public function detail_guru($id) { 
    $query = $this->db->get_where('t_guru', array('id_guru' => $id)); 
    return $query->row_array(); 
} 

//Update Data Guru Setelah Di Edit Di Halaman Edt 
public function edit_guru($data) { 
    $this->db->where('id_guru',$data['id_guru']); 
    return $this->db->update('t_guru',$data); 
}

请参阅编辑（）tim_monitoring的方法/ Data_guru.php多数民众赞成必须需要一个参数传递可变$ ID的价值。

所以，你需要在窗体的行动

action="<?php echo base_url() ?>/tim_monitoring/data_guru/edit/<?php echo $detail['id_guru'] ?>"

添加以下URL上传图像格式必须要求属性enctype="multipart/form-data“
