Question

我有上传多个图像文件的表单，结合了Laravel 4.2和Ajax。但是当上传图像时，输入文件总是为NULL。我该如何解决？

这是我的上传表格。

{{ Form::open(array('url' => route('member.font.upload.images'), 'files'=>true, 'id'=>'upload-images', 'method'=> 'post')) }}
    {{ Form::file('image[]', array('multiple'=>true, 'id'=>'images')) }}
    <input type="hidden" name="font" value="{{ $font->id }}">
{{ Form::close() }}

在Controller中上传流程。

public function uploadImages()
{
$rules = array(
    'font' => 'required'
);

$validator = Validator::make(Input::all(), $rules);

if ($validator->fails()) {
    return Response::json(['success' => false, 'message' => 'Failed upload image']);
} else {
    if(Input::hasFile('image')){
        $images = Input::file('image');
        foreach($images as $image) {
            $imagename = time() . $image->getClientOriginalName();
            $upload =  $image->move('images/', $imagename);

            if($upload){
                $data = new Image;
                $data->font_id      = Input::get('font');
                $data->name         = $imagename;
                $data->save();
            }
        }
        return Response::json(['success' => true, 'message' => 'Success']);
    }else{
        return Response::json(['success' => false, 'message' => 'File not found']);
    }
}
}

然后是Ajax进程。

$('#images').change(function(e) {
e.preventDefault();
$.ajax({
    url: $('#upload-images').attr('action'),
    type: 'post',
    dataType: 'json',
    data: $('#upload-images').serialize(),
    beforeSubmit: function() {
        $('.add-images').removeClass('enabled').addClass('uploading');
    },
    success: function(data) {
        $('.add-images').removeClass('uploading').addClass('enabled');
    },
    error: function() {}
    });
});

Answer 1

您可能需要定义表单的编码类型。

{{ Form::open(array('url' => route('member.font.upload.images'), 'files'=>true, 'id'=>'upload-images', 'method'=> 'post', 'enctype' => "multipart/form-data")) }}

您可以使用此W3Schools doc了解更多详情。

更改此部分：

{{ Form::open(array('url' => route('member.font.upload.images'), 'files'=>true, 'id'=>'upload-images', 'method'=> 'post')) }}

要：

{{ Form::open(array('route' => 'member.font.upload.images', 'files'=>true, 'id'=>'upload-images', 'method'=> 'post')) }}

Laravel 4.2输入文件空
