Question

我是php的新手，我需要上传具有分配给该文件的随机名称的文件，并以随机名称存储该文件，以上传文件夹并将该随机名称存储到mysql数据库中。

  $pic_file1 = $this->input->post('pic_file');

    $pic_file1 = str_replace( "\\", '/', $pic_file1);
    $filename = time().basename($pic_file1);


            $config['upload_path']          = './uploads/';
            $config['allowed_types']        = 'gif|jpg|png';
            $config['max_size']             = 1000;
            //$config['encrypt_name'] = TRUE;
            // $config['overwrite'] = FALSE; 
            $config['file_name'] =  $filename;          

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

            if ( ! $this->upload->do_upload('pic_file'))
            {
                    $error = array('error' => $this->upload->display_errors());
                    print_r($error);
            }
            else
            {
                    $data = array('upload_data' => $this->upload->data());
                   // print_r($data);                       

            }

In your code just uncomment $config['encrypt_name'] = TRUE; 
then automatically your file name store in random name formate or jsut copy below code

 $pic_file1 = $this->input->post('pic_file');

    $pic_file1 = str_replace( "\\", '/', $pic_file1);
    $filename = time().basename($pic_file1);


            $config['upload_path']          = './uploads/';
            $config['allowed_types']        = 'gif|jpg|png';
            $config['max_size']             = 1000;
            $config['encrypt_name'] = TRUE;
            // $config['overwrite'] = FALSE; 
            $config['file_name'] =  $filename;          

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

            if ( ! $this->upload->do_upload('pic_file'))
            {
                    $error = array('error' => $this->upload->display_errors());
                    print_r($error);
            }
            else
            {
                    $data = array('upload_data' => $this->upload->data());
                   // print_r($data);                       

            }

以上代码与任何框架都相关。如果您是php新手，请尝试使用下面提到的简单代码。

$target_dir = "/var/www/html/uploads/"; // this is base path
$imageFileType = strtolower(pathinfo(basename($_FILES["pic_file"]["name"]),PATHINFO_EXTENSION));
$filename = time().$imageFileType; //save this file name to database $filename
$target_file = $target_dir.$filename
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["pic_file"]["tmp_name"]);
    if($check !== false) {
          if (move_uploaded_file($_FILES["pic_file"]["tmp_name"], $target_file)) {
             echo "The file ". basename( $_FILES["pic_file"]["name"]). " has been uploaded on : ".$target_file;
         } else {
             echo "Sorry, there was an error uploading your file.";
         }
    } else {
        echo "File is not an image.";        
    }
}
