codeigniter在数据库中上载图像存储用户文件，而不是图像名称

而不是 控制器： 我的上传目录很好，但当我使用另一种方法并在需要时调用它时，它不会给出我想要的输出。。我为这件事感到非常抱歉

`

视图：

您没有指定输入，也没有向函数返回图像的名称

function uploadImage() {       
  $config['upload_path'] = './uploads/files';
  $config['allowed_types'] = 'gif|jpg|png|jpeg';
  $config['max_size'] = '2048';
  $config['max_width'] = '2000';
  $config['max_height'] = '2000';
  $this->load->library('upload', $config);

  if (!$this->upload->do_upload('userfile')){
    $error = array('error' => $this->upload->display_errors());
    // var_dump($error); die; // check error
  } else {
    $fileName = $this->upload->data();
    return $fileName;
  }
}

function signupPost() {

  if ($this->form_validation->run('signup') == FALSE) {
    // fails wont continue to next page
    $this->signup_view();
  } else {
    // upload image
    $data['UserFile'] = $this->uploadImage();
    // insert data into the database
    $data = array(
       'userId' => $this->input->post('userId'),
       'password' => $this->input->post('password'),
       'emailAddress' => $this->input->post('emailAddress'),
       'userfile'  => $this->input->post('userfile'),
       'branchId'  => $this->input->post('branchId')
    );

   // user data has successfully signed up
   $this->User->signup_client($data);
   redirect('http://localhost/GFC/index.php/main', 'refresh');
 }
}

感谢您的快速回答@muhammadusman。这意味着很多。还有其他可能的原因吗？就像我设置数据库结构的方式一样？。。。没有成功。显示您的数据库结构？没有错误，但数据库中的输出是“userfile”，而不是图像的名称。列：userfile，varchar 255，MIME类型：noneecho$post_image；死亡检查varibale中存储的内容

public function signupPost()
{

    if ($this->form_validation->run('signup') == FALSE) {
        //fails wont continue to next page
        $this->signup_view();
    } else {
        //upload image
        $this->uploadImage();
        //insert data into the database
        $data = array(
            'userId' => $this->input->post('userId'),
            'userfile'  => $this->input->post('userfile'),
            );
        //user data has successfully signed up
        $this->User->signup_client($data);
        redirect('http://localhost/GFC/index.php/main','refresh');
    }
}

<?php 
        $attributes = array("name" => "signupform");
        $hidden = array('userId' => 'userId', 'userfile' => 'userfile');
        echo form_open_multipart("Client_Dashboard/signupPost", $attributes, $hidden);
    ?>
