Question

我尝试使用AJAX上传图片。这是我的HTML代码：

<form id='image_form'>
    <input placeholder="Write a Comment..." type="text" name="wall_comments" id="wall_comments_<?php echo $mw->wall_id; ?>" value="" style="width:200px;" />
    <input id="fileupload" class="comment_image" type="file" name="files" multiple>
    <input  type="button" name="comment_submit" class="comment_submit" id="<?php echo $mw->wall_id; ?>" value="Submit" />
</form>

我的jQuery代码：

$(document).on("click",".comment_submit",function(){

    var fmobj =  new FormData();

    fmobj.append('files', $('#fileupload').files);

    $.ajax({
        url: "<?php echo base_url().'/wall/post_comments'; ?>", // Url to which the request is send
        type: "POST",             // Type of request to be send, called as method
        data: fmobj,              // Data sent to server, a set of key/value pairs (i.e. form fields and values)
        contentType: false,       // The content type used when sending data to the server.
        cache: false,             // To unable request pages to be cached
        processData:false,        // To send DOMDocument or non processed data file it is set to false
        success: function(data)   // A function to be called if request succeeds
          {
            console.log(data);
          }
    });
});

许多链接都提出了AJAX文件上传的建议。我无法理解的一件事是，在我的控制器中，对于相应的操作，如果我打印$_FILE我收到：

{"files":[{"name":"index.html","size":0,"url":"http:\/\/teamworks\/team3\/cen\/files\/index.html","deleteUrl":"http:\/\/teamworks\/team3\/cen\/index.php?file=index.html","deleteType":"DELETE"}]}

<pre>Array
    (
    )

我无法从$_FILE收到任何内容。许多链接建议在控制器中将文件设置为$_FILE['file']，但如何在没有$_FILE的任何内容的情况下继续操作？
