小编sur*_*amy的帖子

Laravel观点:

<form  enctype="multipart/form-data" method="post" name="imagesform" id="imagesform" >
    <input type="hidden" name="_token" value="{{ csrf_token()}}">
    <div>
        <label id="show" for="files" class="button">Upload photo</label>
        <input id="files" name="images" style="visibility:hidden;" type="file">
    </div> 
    <button type="submit"  class="save" id="saveImage" style="border-radius: 8px; padding: 5px 15px;">SAVE</button>
</form>

这是我上传图像的代码(它发生在我的引导程序模型中).当我上传图像并单击提交按钮时,图像应该插入到数据库中,并且应该检索并显示在视图页面上.

Ajax代码:

$("#saveImage").click(function(e){
    // var formdata=new FormData($("#imagesform")[0]);
    //alert(formdata);
    $.ajaxSetup({
        headers: { 'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content') }
    });
    $.ajax({
        url: 'saveImages/{{$dataId}}',
        type: 'POST',
        data:new FormData($("#imagesform")),
        success: function (data) {
            alert(data)
        },
        cache: false,
        processData: false
    });
    return false;
});

这是ajax代码,我试过了.但是formdata的警告显示[object FormData]和浏览器控制台显示Method not allowed exception

Laravel路线:

Route::post('saveImages/{dataId}',['as' …

控制器功能:

public function addImages(Request $request,$imagesProductId)
{
    $product   = Product::create($request->all());
    $filenames = array();

    if ($request->images == '') {
        return Redirect::back()->withErrors(['msg', 'The Message']);
    }

    if () {
    // also need to validate on the extension and resolution of images 
    // (ie., if the validation fails the enum value will be "QCFailed")
    } else {
        foreach ($request->images as $photo) {
            $filename    = substr($photo->store('public/uploadedImages'), 22);
            $filenames[] = asset('storage/uploadedImages/'.$filename);

            ProductsPhoto::create([
                'product_id'    => $product->id,
                'productId'     => $imagesProductId,
                'nonliveStatus' =>"QCVerified",   
                'filename'      => $filename
