Question

请帮我创建一个使用Laravel 5.4的图像上传系统，也可以将文件名保存在数据库中...

我无法找到有关此问题的相关文章，我也尝试了一个youtube教程，但它没有解释如何在数据库上传输文件名，希望你能帮助我谢谢......

到目前为止我的代码已经完成了......

$this->validate(request(), [
        'article_banner' => 'required | mimes:jpeg,jpg,png | max:2000',
        'article_title' => 'required|max:255',
        'article_date' => 'required|date',
        'article_content' => 'required',
        ]
    );

    $article_banner = $request->file('article_banner');
    $article_title = $request->input('article_title');
    $article_date = $request->input('article_date');
    $article_content = $request->input('article_content');

    return $article_banner;
}

每次上传docx时都会出现验证错误...不是图片

这里是article_add.php

    @extends('layouts.app')

@section('content')

Answer 1

将一个功能设为

public function uploadFiles($_destination_path, $images, $new_file_name) { //code to uplaod multiple fiels to path and return paths array wit file names
    $file_name = str_replace(' ', '-', $new_file_name);
    $paths = array('path' => $_destination_path . '/' . basename(Storage::disk($this->diskStorage)->putFileAs($_destination_path, $images, $file_name)),
        'name' => pathinfo($file_name));
    return $paths;
}

并将所需的参数传递给它，如

$image = $request->file('image');
$fileName = $image->getClientOriginalName();
$destinationPath = '/images';
$img_path[] = $this->uploadFiles($destinationPath, $image, $fileName);

您将在img_path []数组变量中获取所需数据。

public function feedbackPost(Request $request, $id)
    {
        $fileName1 = "";
        $fileName2 = "";
        $rules = array(
            'conferencename' =>'required',
            'yourname' =>'required',

        $validator = Validator::make($request->all(), $rules);
        if ($validator->fails()) 
        {
            return back()->with('danger', 'File format not valid');
        }
        else 
        {
            if($file=$request->hasFile('upload_attendees')) {
                $file=$request->file('upload_attendees');
                $fileName1=$file->getClientOriginalName();
                if (!file_exists('uploads/feedback/attendees/'.$id.'')) {

                $destinationPath='uploads/feedback/attendees/'.$id.'';
                $file->move($destinationPath,$fileName1);
            }

            if($file=$request->hasFile('upload_leads')) {

                                        'results' =>$request->results,
                                        'recommendations' =>$request->recommendations,
                                        'key_customers' =>$request->key_customers,
                                        'actions' =>$request->actions,
                                        'business_opportunities' =>$request->business_opportunities,
                                        'other_opportunities' =>$request->other_opportunities,
                                        'upload_attendees' =>$fileName1,
                                        'upload_leads' =>$fileName2,
                                            ]);
            }
        return back()->with('success', 'Thanks! Your Feedback has been Submitted!');
    }

这就是我的方式。你可以试试这个。
