javascript - AJAX上传文件和文本不起作用

Question

我使用这个ajax代码来提交表单并上传多个输入文件。我想通过ajax发送所有表单数据。通过ajax发送文本输入成功，但文件输入未成功!如何更改此代码？

$("#add_order").click(function () {

    //*****get data input
    var formData = new FormData(); 
        formData.append( 'action', 'add_order');
        formData.append( 'customer_name', $('input[name=customer_name]').val());
        formData.append( 'date', $('input[name=date]').val());
        formData.append( 'order_status', $('input:radio[name=order_stautus]').val());
        formData.append( 'total_price', $('input[name=totalprice]').val());
        formData.append( 'quits', $('input[name=quits]').val());
        formData.append( 'debt', $('input[name=debt]').val());
        formData.append( 'desc', $('#desc').val());
        formData.append( 'desc2', $('#desc2').val());

    $.each($("input[type=file]"), function(i, obj) {
        $.each(obj.files,function(j,file){
            formData.append('photo['+i+']', file);
        });
    });
    $.ajax({
        url: "includes/ajax/ajax.php",
        data: formData,
        processData: false,
        contentType: 'multipart/form-data',
        type: 'POST',
        dataType:'json',
        success: function(response){
           //load json data from server and output message     
           if(response.type == 'error'){ //load json data from server and output message     
               output = '<div class="alert alert-danger">'+response.text+'</div>';
           }else{
               output = '<div class="alert alert-danger">'+response.text+'</div>';
           }
           $("#results").append(output).slideDown();
        } 
    });        
});

获取表单数据的PHP代码:

if($_POST['action']=='add_order'){

    $customer_id = 1;
    $date = $_POST['date'];
    $status = $_POST['order_status'];
    $total_price = $_POST['total_price'];
    $quits = $_POST['quits'];
    $debt = $_POST['debt'];
    $desc = $_POST['desc'];
    $desc2 = $_POST['desc2'];

    for($i=0; $i<count($_FILES['photo']['name']); $i++) {
        //Get the temp file path
        $tmpFilePath = $_FILES['photo']['tmp_name'][$i];

        //Make sure we have a filepath
        if ($tmpFilePath != ""){
          //Setup our new file path
          $newFilePath = "../../uploads/orders/" . $_FILES['photo']['name'][$i];

          //Upload the file into the temp dir
          if(move_uploaded_file($tmpFilePath, $newFilePath)) {

            //Handle other code here

          }
        }
      }

formData控制台.log:

根据this , contentType 必须设置为 false 才能上传 ajax 文件。

也许可以尝试将所有文​​件命名为 photo[] 而不是 photo[n]，以便让您的 PHP 服务器处理数组转换。请参阅http://php.net/manual/en/features.file-upload.multiple.php .
