在php函数中读取多个浏览的文件

Question

我有一个带有多浏览字段的前端表单（ajax提交）。我们如何在php中读取浏览的文件并将文件保存到指定的文件夹中。

我已提到此链接。但是没有在pp函数中获取浏览的文件数据 How to upload multiple files using PHP, jQuery and AJAX

请参阅脚本：

var formData = new FormData(jQuery(this).parents('form')[0]);
jQuery.ajax({
            url: "<?php echo Mage::getUrl('a/b/c'); ?>",
            type: 'POST',
            xhr: function() {
                var myXhr = jQuery.ajaxSettings.xhr();
                return myXhr;
            },
            success: function (data) {
                alert("Data Uploaded: "+data);
            },
            data: formData,
            cache: false,
            contentType: false,
            processData: false
        });

这是我的php功能：

public function fileuploadAction() {
      Mage::log('ghj'.count($_POST['file']['name']), null, '107171.log');
      Mage::log($this->getRequest()->getPost(), null, '107172.log');
      for($i=0; $i<count($_FILES['file']['name']); $i++){    
          $target_path = "uploads/";
          $ext = explode('.', basename( $_FILES['file']['name'][$i]));
          $target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext)-1]; 

          if(move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {
              echo "The file has been uploaded successfully <br />";
          } else{
              echo "There was an error uploading the file, please try again! <br />";
          }
      }

该功能未进入循环。也算（$ _ POST ['file'] ['name']）记录0。

如何在函数中读取此表单数据？请帮忙。提前谢谢。
