PHP Codeigniter Do Upload功能不起作用

Question

i want to use do_upload function codeigniter and i have tried to solving this code with any tutorial. Please help me to solve this problem.

in controller:

function simpan_berita(){
    $this->load->library('upload');
    $config['upload_path'] = './assets/images/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg|bmp';
    $config['encrypt_name'] = TRUE;

            $this->upload->initialize($config);
            if(!empty($_FILES['filefoto']['name']))
            {
                if ($this->upload->do_upload('filefoto'))
                {
                    $gbr = $this->upload->data();
                    //Compress Image
                    $config['image_library']='gd2';
                    $config['source_image']='./assets/images/'.$gbr['file_name'];
                    $config['create_thumb']= FALSE;
                    $config['maintain_ratio']= FALSE;
                    $config['quality']= '60%';
                    $config['width']= 840;
                    $config['height']= 450;
                    $config['new_image']= './assets/images/'.$gbr['file_name'];
                    $this->load->library('image_lib', $config);
                    $this->image_lib->resize();

                    ...
                    echo $this->session->set_flashdata('msg','success');
                    redirect('user/berita');
                }else{
                    echo $this->session->set_flashdata('msg','warning');
                    redirect('user/berita');
                }

            }else{
                redirect('admin/berita');
            }
}

and this is my views code:

        <form action="<?php echo base_url().'user/berita/simpan_berita'?>" method="post" enctype="multipart/form-data">
          ...
          <div class="form-group">
            <label>Gambar</label>
            <input type="file" name="filefoto" style="width: 100%;" required>
          </div>
        </div>
      </div>
    </form>

When i try to upload, other else condition will be run:

            else{
                echo $this->session->set_flashdata('msg','warning');
                redirect('user/berita');
            }

i need do_upload condition will be run. Please comment to help. Thankyou..

Two possibilities come to mind...

Either your /assets/images/directory is not accesible (wrong path and/or not writable by codeigniter), in which case you should double check the path and/or try changing permissions of the directory to 777 and, if everything starts working, work your way down to a more reasonable permission level.

Or, this is another case (i've read many, but so far I still thought it was just a hoax) that CI's upload library doesn't seem to like it if you use anything other than userfile as the field name being uploaded. Try changing all references of filefoto to userfile in both the view and the controller and see if it magically starts to work :)
