cakephp 2.0 使用 jQuery Ajax 和参数上传文件 - 仍然无法得到任何答案

Question

我仍然得不到这个问题的任何答案。谁能帮我解决这个问题。

我正在尝试向 select 人发送一封带附件的电子邮件。因此，我从数据库中过滤了数据，并将带附件的电子邮件发送给 selected 用户。

我已经完成了以下回答：

How can I upload files asynchronously?

我已经尝试了 JQuery、Ajax 的以下代码，控制器操作：

<script type="text/javascript">
function SendEmail(){
  var checked=0;
  jQuery("#action_row").val('delete');
  var filename = jQuery("#UserPdf").val();
  var audits    =   '';
  $('.checkboxes:checked').each(function(){
     checked=1;         
     audits +=  this.value+',';  
  });
 var auditsval  =   audits.slice(0, -1);
  //alert(auditsval);
  if(checked==1){
      var con   =   confirm('Are you sure you want to send email?');
      if(con){
          jQuery.ajax({
            type: "POST",
            url: CommanPath.basePath+'admin/users/send_email',
            enctype: 'multipart/form-data',
            data: {
                file: filename,
                ids: auditsval,
            },
            success: function (data) {
                alert("Email sent to selected users ");
            }
        });
      }

  }else{
    alert("Please select atleast one to send email");  
  }

}
</script>

UsersCOntroller.php

public function admin_send_email($id = null){
    //echo 'here'; die;

    $this->layout = 'ajax';
    echo '<pre>'; print_r($_FILES); die;

    if(isset($this->params['data']['file']) && $this->params['data']['file']){

        $filename = time().$this->params['data']['file'];
        move_uploaded_file($_FILES['data']['tmp_name']['file']['name'], WWW_ROOT.'uploads/sellingtools/' . $filename);
    }
    $userids = explode(",", $this->params['data']['ids']);
    echo '<pre>'; print_r($userids); die;
}

当我试图获取上传的文件名时，我只得到文件名而没有得到 tmp_name。

任何人都可以告诉我如何获取 tmp_name 并将文件移动到确切路径。

请帮忙。

您需要使用如下表格和FormData

HTML:

<form id="myForm" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
</form>

JQUERY:

function SendEmail(){
  var checked=0;
  jQuery("#action_row").val('delete');
  var filename = jQuery("#UserPdf").val();
  var audits    =   '';      
  $('.checkboxes:checked').each(function(){
     checked=1;         
     audits +=  this.value+',';  
  });
  var auditsval  =   audits.slice(0, -1);
  //alert(auditsval);

  var formdata = new FormData($('#myForm')[0]); /////formdata object
  formdata.append('ids',auditsval); /// add additional fields 

  if(checked==1){
      var con   =   confirm('Are you sure you want to send email?');
      if(con){
          jQuery.ajax({
            type: "POST",
            url: CommanPath.basePath+'admin/users/send_email',
            processData: false,  ///required to upload file
            contentType: false,  /// required
            data: formdata,       /// send form data
            success: function (data) {
                alert("Email sent to selected users ");
            }
        });
      }

  }else{
    alert("Please select atleast one to send email");  
  }

}
