Ionic File Upload无法正常工作

Question

某些功能不起作用，无论是文件上传部分还是PHP上的接收端。但是，记录确实在数据库中创建，并且用户ID确实已发送。在选择或拍摄图像时，它会显示在HTML img标签内

这是我的PHP

<?php

      $mysqli = new mysqli('127.0.0.1','root','***','pdo_ret');  
      
      // If a connection error occurred, stop here.
      if ($mysqli->connect_error) {  
          die('Could not connect to Socialnetwk DB: ' . $mysqli->error);  
      }

          $conn = new mysqli('127.0.0.1','root','***','pdo_ret');

      // Switch to the ajax_demo schema
          $mysqli->select_db("ajax_demo");

            $date = date('Y-m-d') ."\n";
            $now = time(); $utc_time = $now - intval(date('Z', $now));

            $UsrID = $usid;
            $format = 'img';
            $file_format = 'jpg';
            $MediaTxt = $txtpos;
            $author_id = $usid;
            $relation = 'feed';
            $userID = $usid;

            $MediaTxtNw = strip_tags($MediaTxt, '<h1><h2><h3><h4><h5><h6><img><video><audio><iframe><a>');

            $uploadfilename = $_FILES['file']['tmp_name'];
 
            if(move_uploaded_file($uploadfile)){
                    echo 'File successfully uploaded!';
            } else {
                    echo 'Upload error!';

          $conn->close(); 



        
     }

这是我的控制器

$scope.submit = function() {
     var url = "https://app.socialnetwk.com/feed_post.php";
     //target path may be local or url
     var targetPath = $scope.imgURI;
      var filename = targetPath.split("/").pop();
        var options = {
            fileKey: "file",
            fileName: filename,
            chunkedMode: false,
            mimeType: "image/jpg",
            params : {'uid':$localStorage.session_id, 'textpost':$scope.fposttxt.text}
        };
        $cordovaFileTransfer.upload(url, targetPath, options).then(function(result) {
            console.log("SUCCESS: " + JSON.stringify(result.response));
            alert("success");
            alert(JSON.stringify(result.response));
        }, function(err) {
            console.log("ERROR: " + JSON.stringify(err));
            alert(JSON.stringify(err));
        }, function (progress) {
            // constant progress updates
            $timeout(function () {
            $scope.downloadProgress = (progress.loaded / progress.total) * 100;
          })
        });
    }

这是我的HTML
