Ajax 没有发送图片

Question

我正在提交一个表单，其中一些输入和图像输入并通过 ajax FormData 发送，所有文本数据都已正确提交，在控制器中我可以使用 dd() 看到它但是图像没有数据显示

var formdata= new FormData($(".com_form")[0]);


                        formdata.append('com-name',com_name);

                    //$("#emp-com-form").trigger("reset");

                    $.ajax({
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                        },
                    url:'/company-registration',
                    type:'POST',
                    data:formdata,
                    processData: false,
                    contentType: false,
                    cache: false,
                    dataType:'JSON',
                    enctype: 'multipart/form-data',

                    success:function(data){
                    //window.location.href= 'next-step.html?type='+type;
                    //window.location.href= '/login';
                        console.log(data);

                    },
                    error: function (data) {
                    console.log('Error:', data);
                    }
                    });
                    });

这是 ajax 代码

 public function companyReg(Request $request){

       http_response_code(500);
        dd($request->all());

}

这是控制器代码

您好，您可以在下面看到如何上传图片link。

var formData = new FormData();
formData.append('section', 'general');
formData.append('action', 'previewImg');
// Attach file
formData.append('image', $('input[type=file]')[0].files[0]); 

/** For multiple file upload in different field **/

formData.append('image_input1', $('#image_input1')[0].files[0]);      
formData.append('image_input2', $('#image_input2')[0].files[0]);      

/** For multiple file upload in same field **/ 

let files = $('input[type=file]')[0];
for(let i = 0; i < files.length; i++) {
   formData.append('image['+i+']', files[i]);
}

Answer 2

开发人员，欢迎来到 Whosebug。虽然评论部分的人是对的，你也应该 post 代码，但因为我也遇到了同样的问题。我能理解。我正在 post 编写示例代码，希望它能有所帮助。

    let featuredImage = $('#featured-image');
    if (!typeof (featuredImage.get(0).files[0]) === "undefined") {
        formData.append('featured-image', featuredImage.get(0).files[0]);
    }

    let featuredImage2 = $('#featured-image-2');
    if (!typeof (featuredImage2.get(0).files[0]) === "undefined") {
        formData.append('featured-image-2', featuredImage2.get(0).files[0]);
    }

现在在您的 ajax 调用中使用此 formData。您还将获得文件。您还可以在调用之前添加其他表单字段。

在控制器中：

if ($request->hasFile('featured-image')) {
    $request = $this->moveFeaturedImage($request);
}

/**
 * @param Request $request
 * @return Request
 */
private function moveFeaturedImage(Request $request)
{
    $image = $request->file('featured-image');
    $imageName = createNewImageName($image);
    $image->move(
        public_path(POST_IMAGE_DIR),
        $imageName
    );

    $request->merge([
        'featured_image' => $imageName
    ]);

    return $request;
}

我想现在解释得很好了？
