javascript - JS:How to send multiple files using FormData(jQuery Ajax)

In my form multiple file uploads are there,using FormData only one file is uploading ,though I'm selecting more than one file to upload,following is the code

HTML

<form name="uploadImages" method="post" enctype="multipart/form-data">
<input type="file" name="photo[]" value="">
<input type="file" name="photo[]" value="">
<input type="file" name="photo[]" value="">
</form>

JS

     var ajaxData = new FormData();
     ajaxData.append( 'action','uploadImages');
     jQuery.each($("input[name^='photo']")[0].files, function(i, file) {
        ajaxData.append('photo['+i+']', file);
      });
     $.ajax({
        url: URL,
        data: ajaxData,
        cache: false,
        contentType: false,
        processData: false,
        type: 'POST',
        dataType:'json',
        success: function(data) {
            if (data.status == 'success') {
                location.reload();
            }
        }
       });

I'm using PHP at server,using HTML attribute name i,e photo only I'm able to save files,dynamic file names won't be work for me.

You have an error in javascript: you're iterating only over files in one input please have a look at this

var ajaxData = new FormData();
ajaxData.append( 'action','uploadImages');
$.each($("input[type=file]"), function(i, obj) {
        $.each(obj.files,function(j, file){
            ajaxData.append('photo['+j+']', file);
        })
});

example on jsfiddle
