如何在 Laravel 5.7 中上传数据库中的图像？答案

【问题标题】：How to upload Image in Database in Laravel 5.7?如何在 Laravel 5.7 中上传数据库中的图像？

【问题描述】：

我正在 Laravel 5.7 中制作应用程序。我想通过它上传数据库中的图像，我想从数据库中显示它。

当我遇到问题时，我在互联网上尝试了不同的方法

Intervention\Image\Facades\Image

我听从了互联网上的许多建议，在 config.app 中进行了更改在 Composer

中进行了更改

最后用了

use Intervention\Image\Facades\Image as Image;

所以我从问题“未定义的类图像”中得到解决但现在我遇到了“未定义的类文件”的问题，找不到方法 getClientOriginalExtension。方法升迁，找不到。

我的代码是

<?php


namespace App\Http\Controllers;
use File;
use Intervention\Image\Facades\Image as Image;
use App\User;
use Illuminate\Http\Request;


class UserController extends Controller

{
//

protected $user;

/**
 * [__construct description]
 * @param Photo $photo [description]
 */
public function __construct(
    User $user )
{
    $this->user = $user;
}

/**
 * Display photo input and recent images
 * @return view [description]
 */
public function index()
{
    $users = User::all();
    return view('profile', compact('users'));
}

public function uploadImage(Request $request)
{
    $request->validate([
        'image' => 'required',
        'image.*' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
    ]);

    //check if image exist
    if ($request->hasFile('image')) {
        $images = $request->file('image');

        //setting flag for condition
        $org_img = $thm_img = true;

        // create new directory for uploading image if doesn't exist
        if( ! File::exists('images/originals/')) {
            $org_img = File::makeDirectory('images/originals/', 0777, true);
        }
        if ( ! File::exists('images/thumbnails/')) {
            $thm_img = File::makeDirectory('images/thumbnails', 0777, true);
        }

        // loop through each image to save and upload
        foreach($images as $key => $image) {
            //create new instance of Photo class
            $newPhoto = new $this->user;
            //get file name of image  and concatenate with 4 random integer for unique
            $filename = rand(1111,9999).time().'.'.$image->getClientOriginalExtension();
            //path of image for upload
            $org_path = 'images/originals/' . $filename;
            $thm_path = 'images/thumbnails/' . $filename;

            $newPhoto->image     = 'images/originals/'.$filename;
            $newPhoto->thumbnail = 'images/thumbnails/'.$filename;

            //don't upload file when unable to save name to database
            if ( ! $newPhoto->save()) {
                return false;
            }

            // upload image to server
            if (($org_img && $thm_img) == true) {
                Image::make($image)->fit(900, 500, function ($constraint) {
                    $constraint->upsize();
                })->save($org_path);
                Image::make($image)->fit(270, 160, function ($constraint) {
                    $constraint->upsize();
                })->save($thm_path);
            }
        }
    }

    return redirect()->action('UserController@index');

}

}

请在不更新存储库的情况下向我建议任何图像上传代码，或者建议我如何从该代码中删除问题。

【问题讨论】：

我要上传图片到数据库 - 意思是你想把blob存到数据库里，还是把path/to/your/image.jpg存到数据库里？
图像到数据库...
你不明白我的意思。您可以存储图像文件的路径或将图像存储为二进制对象

标签： php database laravel image laravel-5

【解决方案1】：

$upload_id = $request->file('FILENAME');
$file_name = time().$upload_id->getClientOriginalName();
$destination = 
$_SERVER["DOCUMENT_ROOT"].'/adminbusinessplus/storage/uploads';
$request->file('FILENAME')->move($destination, $file_name);


$string="123456stringsawexs";
$extension = pathinfo($upload_id, PATHINFO_EXTENSION);
$path = $destination.'/'.$file_name;
$public =1;
$user_id = $request->logedin_user_id;
$hash = str_shuffle($string);

$request->user_id = $request->logedin_user_id;
$request->name = $file_name;
$request->extension = $extension;
$request->path = $path;
$request->public = $public;
$request->hash = $hash;

//$request INSERT INTO MODEL uploads
$file_id = Module::insert("uploads", $request);

【解决方案2】：

开始阅读以下链接，因为 laravel 处理了创建目录和哈希图像并放置目录 laravel file system 然后读取存储在目录中的文件名，并在需要图像检索名称字段并调用服务器上的物理地址时在表字段中保存名称
