如何將圖像保存到我的數據庫中？

在我的頁面中，我創建了一個包含名稱，電子郵件，密碼等不同字段的表單，現在我必須上傳圖像並存儲在我的數據庫中。任何人都會發送包含圖片上傳文件在內的所有字段的代碼。我必須多次嘗試，圖像無法上傳到我的數據庫中。如何將圖像保存到我的數據庫中？

我控制器

function activity() { 
    $this->load->library('form_validation'); 
    //field name,error message, validation rules 
    $this->form_validation->set_rules('activityid', 'Activity Id', 'trim|required'); 
    $this->form_validation->set_rules('hostid', 'Host Id', 'trim|required'); 
    $this->form_validation->set_rules('activityname', 'Activity Name', 'trim|required'); 
    $this->form_validation->set_rules('date', 'Date', 'trim|required'); 
    $this->form_validation->set_rules('venue', 'Venue', 'trim|required'); 
    $this->form_validation->set_rules('typeofactivity', 'Type of Activity', 'trim|required'); 
    $this->form_validation->set_rules('conductedby', 'Conducted By', 'trim|required'); 
    if ($this->form_validation->run() == FALSE) { 
     //$this->load->view('signup_form'); 
     $this->activity_reg(); 
    } else { 
     $this->load->model('membership_model'); 

     $query = $this->membership_model->activity(); 

     if ($query) { 
      $data['main_content'] = 'signup_successful'; 
      $this->load->view('includes/templates', $data); 
     } else { 
      $this->load->view('activity'); 
     } 
    } 
}

我的模型是

function activity() { 
    $new_member_insert_data = array(
     'activityid' => $this->input->post('activityid'), 
     'hostid' => $this->input->post('hostid'), 
     'activityname' => $this->input->post('activityname'), 
     'date' => $this->input->post('date'), 
     'venue' => $this->input->post('venue'), 
     'typeofactivity' => $this->input->post('typeofactivity'), 
     'conductedby' => $this->input->post('conductedby') 
    ); 

    $this->load->database(); 
    $insert = $this->db->insert('activity', $new_member_insert_data); 
    return $insert; 
}

爲什麼圖像數據庫保存？只使用它的名字而不是圖片本身。 – Abhishek

向我發送代碼，我會嘗試 – abu

檢查下面的鏈接它會給你一個想法http://ellislab.com/codeigniter%20/user-guide/libraries/file_uploading.html分配後只更新數據庫表中的uniqueimage名稱 – Abhishek
