在codeigniter中上傳文件

Question

雖然我選擇了要上傳的文件，但試圖上傳文件時收到錯誤消息You did not select a file to upload.。我正在使用使用bootstrap的樣式的輸入文件。這是問題嗎？我按照Codeigniter用戶指南中的說明進行文件上傳。任何人都可以幫助我，並確定我的代碼中的錯誤？

謝謝

public function create() 
{ 
    $config['upload_path']   = './uploads/'; 
    $config['allowed_types']  = 'gif|jpg|png'; 

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

    if (! $this->upload->do_upload('userfile')) 
    { 
      echo "Upload failed"; 
    } 
    else 
    { 
      $data = array('upload_data' => $this->upload->data()); 

    } 

    $data = array(
     'category' => $this->input->post('category'); 
     'name' => $this->input->post('recipename'), 
     'ingredients' => $this->input->post('ingredients'), 
     'directions' => $this->input->post('directions'), 
     'date' => date("Y/m/d") 

    ); 

    $this->model->insert($data); 
    redirect('', 'refresh'); 
}

使用加密類型在你的HTML表單標籤。

<form action="<?php echo base_url();?>home/create" method="POST" role="form" enctype="multipart/form-data" > 

現在試試。它會工作。:)
