php - 使用多个参数将图像上传到服务器

Question

我正在尝试将图像上传到服务器，我已经完成并且效果很好。但我面临的问题是我想上传图片并传递一些参数，比如手机号码。

我是 android 的新手，对 PHP 端编码也一无所知，， 我尝试了以下代码来上传图片，我添加了几行以通过该图片传递手机号码。我真的不知道这种方法是否正确，但如果我错了请纠正我...

            }
        }
        return sb.toString();
        }
    }
}

这是保存图片的服务器端代码..

<?php

       $file_path = "uploads/";

       $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
       if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
           echo "success";
       } else{
           echo "fail";
       }
?>

请告诉我如何在服务器端获取该手机号码？？？

Answer 1

我最近用 PHP CodeIgniter 做了这个:

Android 端:

/*** POST THIS CODE AFTER
dos = new DataOutputStream(conn.getOutputStream()); 
***/

dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=mobile_no" + lineEnd); // name=mobile_no so you have to get PHP side using mobile_no
dos.writeBytes(lineEnd);
dos.writeBytes(mobile_number); // mobile_no is String variable
dos.writeBytes(lineEnd);

PHP 端(核心 PHP):

$mobile_no = $_POST['mobile_no'];

PHP 端(使用 CodeIgniter 框架):

$mobile_no => $this->input->post('mobile_no');
