上传多个图像并调整jquery ajax php的大小

Question

我正在尝试在html，jquery ajax和php中创建一个图库。到目前为止它的工作率为90％我会说，图像被上传到一个特定的文件夹并保存到数据库中，但是当我同时从6张图片开始上传时，我遇到了一些问题，有些图片调整得非常小而不是采取我在代码中给出的值。

这是我的HTML：

<form id="upload-images-form" enctype="multipart/form-data">
  <input type="file" name="imagesinput[]" id="imagesinput" multiple="multiple" accept="image/jpeg">
  <input id="upload-images-button" class="btn btn-success" name="submit" type="submit" value="Subir"/>
</form>

我的jquery：

$('#upload-images-form').on("submit", function(e){

   e.preventDefault();
            console.log("uploading images");

   var formData = new FormData(this);

   var request = $.ajax({
      method: "POST",
      url: "upload_gallery/",
      cache: false,
      processData: false,
      contentType: false,
      data: formData,
      xhr: function() {
        var xhr = $.ajaxSettings.xhr();
        progressBar.parent().css('display','block');
        if (xhr.upload) {
           xhr.upload.addEventListener('progress', function(event) {
              var percent = 0;
              var position = event.loaded || event.position;
              var total = event.total;
              if (event.lengthComputable) {
                 percent = Math.ceil(position / total * 100);
              }
              //update progressbar
                progressBar.css("width", + percent +"%");
                progressBar.text(percent +"%");
           }, true);
        }
         return xhr;
      },
      mimeType:"multipart/form-data"
   });
   request.done(function( msg ) {
      console.log(msg);
   });
   request.fail(function( jqXHR, textStatus ) {
      console.log( "Request failed: " + textStatus );
   });
});

最后我的PHP，我处理和验证图像;

$images = $_FILES['imagesinput'];
$responses = array();
$resized_width = 1000; //new max-width for images
$resized_height = 700; // new max-height for images

if(isset($_FILES['imagesinput'])){

   $img_desc = reArrayFiles($images); // function to help handling the array coming from ajax

   $i = 0;
   $len = count($img_desc);

   foreach($img_desc as $val){ // array loop

      if($val['size'] <= 5 * 1024 * 1024){ // size validation

         if($val['type'] == "image/jpeg" || $val['type'] == "image/jpg"){ // format validation

            if(!is_dir(ROOT_URI.'/gallery/user_id_'.$id)){ // check if folder exist

               mkdir(ROOT_URI.'/gallery/user_id_'.$id, 0777);

            }

            $total_files = new FilesystemIterator('../../gallery/user_id_'.$id); // limit images

            if(iterator_count($total_files) === 20){

               array_push($responses, 'alert_total_files');
               echo json_encode($responses);
               die;

            }

            list($original_width, $original_height) = getimagesize($val['tmp_name']); // get image size

            $original_ratio = $original_width/$original_height;

            if ($resized_width / $resized_height > $original_ratio) {
               $resized_width = $resized_height * $original_ratio;
            } else {
               $resized_height = $resized_width / $original_ratio;
            }

            // resize image(proportional)
            $image_p = imagecreatetruecolor($resized_width, $resized_height);
            $resized_image = imagecreatefromjpeg($val['tmp_name']);
            imagecopyresampled($image_p, $resized_image, 0, 0, 0, 0, $resized_width, $resized_height, $original_width, $original_height);

            // verificar de que la imagen no existe, si existe, no se sube
            if(!file_exists('../../gallery/user_id_'.$id.'/'.$val['name'])){

               $conn = mysqli_connect($servername, $username, $password, $db);

               /* check connection */
               if (mysqli_connect_errno()) {
                  printf("Connect failed: %s\n", mysqli_connect_error());
                  exit();
               }

               imagejpeg($image_p, ROOT_URI.'/local_gallery/local_id_'.$id.'/'.$val['name']);

               $path_url = BASE_URI.'app/gallery/user_id_'.$id.'/'.$val['name'];

               $insert =  mysqli_prepare($conn, "INSERT INTO user_gallery (id_user, path_url) VALUES (?, ?)");

               mysqli_stmt_bind_param($insert, "ss", $id, $path_url);

               if(mysqli_stmt_execute($insert)){

                  array_push($responses, 'alertsuccess');

               }

               imagedestroy($image_p);

             }
             else{
                array_push($responses, 'file_exists');

             }


           }
           else{

              array_push($responses, 'alertformat');

           }


        }
        else{

           array_push($responses, 'alertsize');

        }

        if($i == $len - 1){
           echo json_encode($responses);
        }

        $i++;

     }

}

function reArrayFiles($file){
   $file_ary = array();
   $file_count = count($file['name']);
   $file_key = array_keys($file);

   for($i=0;$i<$file_count;$i++){
    foreach($file_key as $val){
        $file_ary[$i][$val] = $file[$val][$i];
    }
   }
   return $file_ary;
 }

我正在试图理解可能是什么问题，我只是觉得可能是因为循环太快而无法提供正确的值，所以它仍然需要来自普通图像的旧值？

一些线索？我真的很感激，谢谢。
