我有一个注册表，要求提供名字、姓氏、电子邮件等详细信息，并要求在最后上传一个 pdf 文件。我没有使用任何数据库，我使用服务器中的 php 将所有详细信息存储在 json 文件中。我能够将数据以及 pdf 文件存储在目录路径中，我无法弄清楚我应该如何将 pdf 与用户详细信息连接起来（即如何存储 pdf 以便它在 json 文件中有一个字段所以当用户下次登录时，他应该能够看到他的 pdf 文件）。

下面是存储pdf文件的php文件：

<?php
  header('Access-Control-Allow-Origin: *');
  header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
  header('Access-Control-Allow-Methods: GET, POST, PUT');

  $userId = $_POST['userId'];
  $type = $_POST['type'];
  $model = array();
  $uploaded = false;
  $found = false;
  $imgDir = 'data/transcripts/';

  $users = json_decode(file_get_contents('../data/studentdata.json'));
  switch ($type) {
    case 'cis300':
      $model = $users->cis300;
      break;

    case 'cis400':
      $model = $users->cis400;
      break;

    case 'cis500':
      $model = $users->cis500;
      break;
  }
  if (isset($_FILES["file"]["name"])) {
    foreach ($model as $key => $user) {
      if ($user->id == $userId) {
        $found = true;
        $temp = explode(".", $_FILES["file"]["name"]);
        $newfilename =  str_replace(' ', '', ($user->firstname . $user->lastname)) . '-' . date('Y-m-d-h-m-s') . '.' . end($temp);
        if (move_uploaded_file($_FILES["file"]["tmp_name"], '../data/transcripts/' . $newfilename)) {
          unlink('../' . $user->tfile);
          $uploaded = true;
          $fileName = str_replace(' ', '', ($user->firstname . $user->lastname)) . $user->year;
          $user->tfile = $imgDir . $newfilename;
          echo json_encode(array('uploaded' => $uploaded, 'user' => $user));
        } else {
          echo json_encode(array('uploaded' => $uploaded, 'user' => array()));
        }
        break;
      }
    }
    if ($found) {
      unlink('../data/studentdata.json');
      file_put_contents('../data/studentdata.json', json_encode($users, JSON_PRETTY_PRINT));
    }
    if (!$found) {
      echo json_encode(array('uploaded' => $uploaded, 'user' => array()));
    }
  }
?>

下面是我获得请求和上传功能的 Angular js 文件：

csel.controller('studentController', function (AppServices, $rootScope, $scope, Upload, $http, $routeParams, $timeout, $location) {

$scope.formdata.tfile = function () {
        if ($scope.forms.registerForm.file.$valid && $scope.formdata.file) {
            $scope.upload($scope.formdata.file);
        }
    };
    $scope.upload = function (file) {
            file.upload = Upload.upload({
                url: $rootScope.baseURL + 'php/uploadT.php',
                data: {
                    file: file,
                    'userId': $scope.formdata.id, 
                    'type': $scope.formdata.type
                },
            });

            file.upload.then(function (response) {
                $timeout(function () {
                    console.log("CAlled in Upload");
                    file.result = response.data;
                });
            }, function (response) {
                if (response.status > 0)
                    $scope.errorMsg = response.status + ': ' + response.data;
            }, function (evt) {
                file.progress = Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
            });
        }

当我按下上传文件时，文件被上传，但是文件路径存储在不同的 json 对象中。

先感谢您！
