更新数据库中的数据和上传照片不工作

Update data in db and upload photo not working

当我想更新数据库表中有图像上传的记录时，它不能上传图像，但所有其他数据更新成功下面是更新函数:

$config['upload_path'] = './img/products/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '0';
$config['max_width']  = '0';
$config['max_height']  = '0';
$this->load->library('upload', $config);

if ( ! $this->upload->do_upload())
{
    $error = array('error' => $this->upload->display_errors());
    $this->load->view('admin/admin_header_view');
    $this->load->view("admin/admin_menu_view");
    $this->load->view('admin/admin_rewarding_view', $error);
    $this->load->view('admin/admin_footer_view');
}
else
{
    $data = array('upload_data' => $this->upload->data());
    $filename = $data['upload_data']['file_name'];
    $data= array(
        'reward' => $this->input->post('reward'),
        'amount_of_points' => $this->input->post('amount_of_points'),
        'img' => $filename
    );
    $this->db->where('id',$this->input->post('id'));
    $this->db->update('rewards',$data);
    redirect("admin/rewarding_system");
}

if ( ! $this->upload->do_upload($this->input->post('upload_name_attr')) //or however you are getting this file to the server
{
    $error = array('error' => $this->upload->display_errors());
    $this->load->view('admin/admin_header_view');
    $this->load->view("admin/admin_menu_view");
    $this->load->view('admin/admin_rewarding_view', $error);
    $this->load->view('admin/admin_footer_view');
}

使用这个。我在以身作则。根据需求，进行必要的变更。这就是我上传文件的方法。这对你也有帮助。就这样过一遍。那里有很多垃圾代码，都忽略了。想用什么就用什么。希望。我帮了你。

           $FileUpload=$this->news_model->UploadEditedFiles($EncFileName,$FileID,$FileTitle,$FileDescription);
           if($FileUpload=='True')
            {
                redirect('welcome/editrecord/'.$FileID);
            }
        }
    }
}

}

<?php
class News_model extends CI_Model {
        public function __construct()
        {
                $this->load->database();
        }
public function UploadEditedFiles($EncFileName,$FileID,$FileTitle,$FileDescription)
    {
        $data = array('FilePath' => $EncFileName,'FileID'=>$FileID);
        $this->db->where('FileID', $FileID);
        $this->db->insert('MemberFiles', $data);
}
}

检查您的Initialization:

$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->upload->initialize($config);
$this->load->library('upload', $config);
