在laravel中上传AJAX文件

Question

自从过去两天以来,我一直在努力让ajax文件上传工作在lavvel 4中,我现在好运.

我的jquery块

$(document).ready(function(){

$('#basicModuleImage').change(function () {
    sendFile(this.files[0]);
});

function sendFile(file) {

  $.ajax({
    type: 'post',
    url: '/upload',
    data: file,
    enctype: 'multipart/form-data',
    success: function (data) {
            alert(data);
    },
    processData: false,
    contentType: file.type
  });
}
 });

HTML块

 <form method="post" action="">
 <input type="file" id="basicModuleImage" name="basicModuleImage" />
 </form>

LARAVEL PHP块

Route::post('upload', function(){

return Response::json(array('a'=>var_dump(Input::all()),'b'=>var_dump($_FILES)));

});

我也尝试过使用https://github.com/LPology/Simple-Ajax-Uploader,但这似乎与laravel有关.

JSON响应返回a和b都为null.

关键在于你的ajax请求.在控制器中,您可以随心所欲.

var form = document.forms.namedItem("yourformname"); // high importance!, here you need change "yourformname" with the name of your form
var formdata = new FormData(form); // high importance!

$.ajax({
    async: true,
    type: "POST",
    dataType: "json", // or html if you want...
    contentType: false, // high importance!
    url: '{{ action('yourController@postMethod') }}', // you need change it.
    data: formdata, // high importance!
    processData: false, // high importance!
    success: function (data) {

        //do thing with data....

    },
    timeout: 10000
});
