My controller code for upload file in laravel 5.4:
我在 Laravel 5.4 中上传文件的控制器代码：
if ($request->hasFile('input_img')) {
if($request->file('input_img')->isValid()) {
try {
$file = $request->file('input_img');
$name = rand(11111, 99999) . '.' . $file->getClientOriginalExtension();
$request->file('input_img')->move("fotoupload", $name);
} catch (Illuminate\Filesystem\FileNotFoundException $e) {
}
}
}
Image was successfully uploaded but the code threw an exception :

You can use it by easy way, through storemethod in your controller
您可以通过store控制器中的方法以简单的方式使用它
like the below
像下面这样
First, we must create a form with file input to let us upload our file.
首先，我们必须创建一个带有文件输入的表单来让我们上传我们的文件。
{{Form::open(['route' => 'user.store', 'files' => true])}}
{{Form::label('user_photo', 'User Photo',['class' => 'control-label'])}}
{{Form::file('user_photo')}}
{{Form::submit('Save', ['class' => 'btn btn-success'])}}
{{Form::close()}}
Here is how we can handle file in our controller.
这是我们如何在控制器中处理文件。
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class UserController extends Controller
{
public function store(Request $request)
{
// get current time and append the upload file extension to it,
// then put that name to $photoName variable.
$photoName = time().'.'.$request->user_photo->getClientOriginalExtension();
/*
talk the select file and move it public directory and make avatars
folder if doesn't exsit then give it that unique name.
*/
$request->user_photo->move(public_path('avatars'), $photoName);
}
}
That's it. Now you can save the $photoNameto the database as a user_photofield value. You can use asset(‘avatars')function in your view and access the photos.
就是这样。现在您可以将 保存$photoName到数据库中作为user_photo字段值。您可以asset(‘avatars')在视图中使用功能并访问照片。

Use the following code:
使用以下代码：
$imageName = time().'.'.$request->input_img->getClientOriginalExtension();
$request->input_img->move(public_path('fotoupload'), $imageName);

A good logic for your application could be something like:
您的应用程序的一个好的逻辑可能是这样的：
public function uploadGalery(Request $request){
$this->validate($request, [
'file' => 'required|image|mimes:jpeg,png,jpg,bmp,gif,svg|max:2048',
]);
if ($request->hasFile('file')) {
$image = $request->file('file');
$name = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/storage/galeryImages/');
$image->move($destinationPath, $name);
$this->save();
return back()->with('success','Image Upload successfully');
}
}

public function store()
{
$this->validate(request(), [
'title' => 'required',
'slug' => 'required',
'file' => 'required|image|mimes:jpg,jpeg,png,gif'
]);
$fileName = null;
if (request()->hasFile('file')) {
$file = request()->file('file');
$fileName = md5($file->getClientOriginalName() . time()) . "." . $file->getClientOriginalExtension();
$file->move('./uploads/categories/', $fileName);
}
Category::create([
'title' => request()->get('title'),
'slug' => str_slug(request()->get('slug')),
'description' => request()->get('description'),
'category_img' => $fileName,
'category_status' => 'DEACTIVE'

return redirect()->to('/admin/category');

Intervention Image is an open source PHP image handling and manipulation libraryhttp://image.intervention.io/
Intervention Image 是一个开源的 PHP 图像处理和操作库http://image.intervention.io/
This library provides a lot of useful features:
这个库提供了很多有用的功能：
Basic Examples
基本示例
// open an image file
$img = Image::make('public/foo.jpg');
// now you are able to resize the instance
$img->resize(320, 240);
// and insert a watermark for example
$img->insert('public/watermark.png');
// finally we save the image as a new file
$img->save('public/bar.jpg');
Method chaining:
方法链：
$img = Image::make('public/foo.jpg')->resize(320, 240)->insert('public/watermark.png');

提示：（在你的情况下）https://laracasts.com/discuss/channels/laravel/file-upload-isvalid-returns-false
Tips 1:
提示1：
// Tell the validator input file should be an image & check this validation
$rules = array(
'image' => 'mimes:jpeg,jpg,png,gif,svg // allowed type
|required // is required field
|max:2048' // max 2MB
|min:1024 // min 1MB
);
// validator Rules
$validator = Validator::make($request->only('image'), $rules);
// Check validation (fail or pass)
if ($validator->fails())
{
//Error do your staff
} else
{
//Success do your staff
};
Tips 2:
提示2：
$this->validate($request, [
'input_img' =>
'required
|image
|mimes:jpeg,png,jpg,gif,svg
|max:1024',
]);
Function:
功能：
function imageUpload(Request $request) {
if ($request->hasFile('input_img')) { //check the file present or not
$image = $request->file('input_img'); //get the file
$name = "//what every you want concatenate".'.'.$image->getClientOriginalExtension(); //get the file extention
$destinationPath = public_path('/images'); //public path folder dir
$image->move($destinationPath, $name); //mve to destination you mentioned
$image->save(); //

i think better to do this
我认为最好这样做
if ( $request->hasFile('file')){
if ($request->file('file')->isValid()){
$file = $request->file('file');
$name = $file->getClientOriginalName();
$file->move('images' , $name);
$inputs = $request->all();
$inputs['path'] = $name;
}
}
Post::create($inputs);
actually imagesis folder that laravel make it automatic and fileis name of the input and here we store name of the image in our path column in the table and store image in public/images directory
实际上images是laravel使其自动的文件夹，file是输入的名称，在这里我们将图像的名称存储在表的路径列中，并将图像存储在public/images目录中

{
$this->validate($request, [
// check validtion for image or file
'uplode_image_file' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',

// rename image name or file name
