使用FormData和PHP上载多个文件

Question

我遇到了一个问题，我可以从一个表单中选择多个文件，但是当我在PHP中检查它时，它仅显示一个文件（但是在我的浏览器的控制台中，它显示两个文件），而没有请勿将文件移动到新位置。我不太确定发生了什么。

这是我的代码：

jQuery：

   $('#add-items-submit').on('click', function() {
     var store_name = $('#main-store-name').text();
     var item_name = $('#add-item-name').val();
     var item_price = $('#add-item-price').val();
     var item_desc = $('#add-item-desc').val();
     var item_num = $('#add-item-number').val();

     var formData = new FormData();

     formData.append('store_name', store_name);
     formData.append('item_name', item_name);
     formData.append('item_price', item_price);
     formData.append('item_desc', item_desc);
     formData.append('item_num', item_num);

     if (document.getElementById('add-item-image') == null) {
         document.getElementById('add-items-message').value = "Please add an image of the item if you wish to submit it";
     }

     $.each($('#add-item-image')[0].files, function (i, file) {
        formData.append('item_file', file);
     });

     $.ajax({
        type: "POST",
        contentType: false,
        processData: false,
        url: '/user/add-items',
        dataType: "json",
        data: formData
     }).done(function (msg) {
        console.log(msg);
        $('#add-items-message').html(msg.success);
     }).fail(function (msg) {
        console.log(msg);
        $('#add-items-message').html(msg.failure);
     });
  });

PHP代码：

 public function additemsAction()
 {
    $layout = $this->layout();
    $layout->setTerminal(true);

    $view_model =  new ViewModel();
    $view_model->setTerminal(true);

    if ($this->getRequest()->isPost()) {
        try {
            $store_name = $this->params()->fromPost('store_name');
            $item_name = $this->params()->fromPost('item_name');
            $item_price  = $this->params()->fromPost('item_price');
            $item_desc = $this->params()->fromPost('item_desc');
            $item_num = $this->params()->fromPost('item_num');
            $item_image = $this->params()->fromFiles('item_file');

            var_dump($item_image);

            if ($this->getUserService()->addItemsToStore($store_name, $item_name, $item_desc, $item_image, $item_num, $item_price)) {
                echo json_encode(array('success' => 'Item was successfully added to your store'));
            }
        } catch (\Exception $e) {
            echo json_encode(array('failure' => $e->getMessage()));
        }
    }


    return $view_model;
}

if (!is_dir(realpath(getcwd()) . '/public/images/uploads/store/' . $owner_id . '/' . $this->store_name . '/items')) {
    mkdir(realpath(getcwd()) . '/public/images/uploads/store/' . $owner_id .  '/' . $this->store_name . '/items', 0777, true);
}

for ($i=0; $i<count($item_image); $i++) {
   if (is_uploaded_file($item_image['tmp_name'][$i])) {
       move_uploaded_file($item_image['tmp_name'][$i], realpath(getcwd()) . '/public/images/uploads/store/' . $owner_id . '/' . $this->store_name . '/items/' . $item_image['name'][$i]);

        $this->imagick = new \Imagick(realpath(getcwd()) . '/public/images/uploads/store/' . $owner_id .  '/' . $this->store_name . '/items/' . $item_image['name'][$i]);
        // automatically enhance them
        $this->imagick->enhanceImage();

        $this->imagick->writeImagesFile(fopen(realpath(getcwd()) . '/public/images/uploads/store/' . $owner_id .  '/' . $this->store_name . '/items/' . $item_image['name'][$i], 'wb'));
   }
}

因此，基本上，它没有将文件移动到新位置，也没有在文件上执行imagick的功能，但是我检查了日志，并且apache日志中没有写入错误，所以我真的很困惑。哦，我确实使用了var_dump，结果是"array(5) {↵ ["name"]=>↵ string(40) "80E0C7D8-CEB1-49E5-839F-A08F0DE798CB.jpg"↵ ["type"]=>↵ string(10) "image/jpeg"↵ ["tmp_name"]=>↵ string(24) "C:\xampp\tmp\php89B6.tmp"↵ ["error"]=>↵ int(0)↵ ["size"]=>↵ int(68903)↵}

因此formData正在选择所有文件，但是PHP仅显示一个文件，而不显示多个文件。

任何帮助将不胜感激。

谢谢。
