控制器：

public function task_assign()
{

    $name=$this->session->userdata('name');

    date_default_timezone_set('Asia/Calcutta');

    $config = array(
            'upload_path' => "./uploads/",
            'overwrite' => TRUE,
            'max_size' => "2048000",
            );

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

    $this->upload->do_upload();

    $data=array('upload_data' => $this->upload->data());

    $task=array(
            'title'=>$this->input->post('task_title'),
            'description'=>$this->input->post('task_description'),
            'priority'=>$this->input->post('task_priority'),
            'status'=>'Ongoing',
            'start_date'=>$this->input->post('task_start'),
            'due_date'=>$this->input->post('task_due'),
            'end_date'=>$this->input->post('task_due'),
            'assigned_to'=>$this->input->post('task_to'),
            'assigned_by'=> $name,
            'time'=> date('d-m-Y H:i:s'),
            'task_file' => $upload_data['file_name'],
            'additional_info'=>$this->input->post('task_info')
        );
    print_r($task);
    $assign=$this->assign_model->assign_task($task);

    if($assign)
    {
        $this->session->set_flashdata('error_msg', 'Could not Assign task');
        redirect('assign'); 
    }
    else
    {
        $this->session->set_flashdata('success_msg', 'Task Assigned to ' .$task['assigned_to']. ' Successfully...');
        redirect('assign');
    }
}

型号：

class Assign_model extends CI_model{

/* Loading Parent Construct */

function __construct()  
{  
  parent::__construct();
}

/* Get User Data From User Table */

public function fetchtable()
{
  $query = $this->db->get('user');  
  return $query;
}

/* Insert Task Into 'issues' Database */

public function assign_task($task)
{
  $this->db->insert('issues', $task);
}

}

我认为文件名应该在控制器中提供上传。但我不知道如何添加它。

此处只有文件上传和获取文件名。请帮我这样做..
