in My laravel 5.6 app I have image store function in my Controller like this,
public function store(Request $request)
{
$image = new Category();
if ($request->hasFile('image')) {
$dir = 'images/';
$extension = strtolower($request->file('image')->getClientOriginalExtension()); // get image extension
$fileName = str_random() . '.' . $extension; // rename image
$request->file('image')->move($dir, $fileName);
$image->categoryimage = $fileName;
}
$image->save();
}
now I need validate before save image if saving without image (empty) and if not file format is equel to (png,jpeg,png). how can I do this?
In the first line of your function
$validatedData = $request->validate([
'image' => 'required|file|mimes:jpeg,png'
]);
//image is valid
Take a look at this: docs
You can do this:
//first you should use the Request class at the top of your file
use Illuminate\Http\Request;
public function store(Request $request)
{
$validator = $request->validate([
'image' => 'required|image'
]);
if ($validator->fails()) {
// write what you want here
}
// the rest of your code
}
The file under validation must be an image (jpeg, png, bmp, gif, or svg).

I'm making an app in Laravel 5.7 . I want to upload image in database through it and I want to show it from database.
I have tried different methods around the Internet as I was getting issues in
Intervention\Image\Facades\Image
I followed many advices from Internet make changes in config.app
made changes in Composer
At the end used
use Intervention\Image\Facades\Image as Image;
So I get resolved from issue "Undefined class Image"
but now I' m getting issues as "Undefined class File",
Method getClientOriginalExtension not found.
Method Upsize, make not found.
My code is
<?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');
}
}
Please suggest me any Image Upload code without updating repositories or suggest me how can I remove issues from this code.
The beginning of time read below link because laravel handled create directory and hash image and put directory
laravel file system
then read file name when stored on directory and holds name on table field when need image retrieve name field and call physical address on server
$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", $request);
I'm trying to upload an image using storage folder, and also using traits, but when it comes using Intervention i'm really having trouble where to use it.
Here's the FileUploadTrait.php
public function uploadImage($image) {
if ($image) {
$image_name = $image->store('public');
$name = explode("/", $image_name);
$img_name = $name[count($name) - 1];
return $img_name;
}
return null;}}
ProjectsControler.php
public function store(Request $request, Project $project)
{
$this->validate($request, array(
'image' =>'required|image|dimensions:min_width=800,min_height=600'
));
if ($request->hasfile('image')) {
$img_name= $this->uploadImage($request->image);
$image_resize = Image::make($request->image);
$image_resize->resize(800, 600);
}
$projects = Project::create(
array_merge(
$request->except('image', '_token'),
["image"=>$img_name ?? null]
)
);
return redirect('my/path');
}
the image gets uploaded but not resized.
After upload and resizing you have also to save the image to a given destination.
if ($request->hasfile('image')) {
$img_name= $this->uploadImage($request->image);
$image_resize = Image::make($request->image);
$image_resize->resize(800, 600)->save('Your Path');
}
You’re not saving your new resized image.
$image_resize->save();
I have a function to upload file.
public function upload(UploadImageRequest $request)
{
$data = Request::input('image_url')) {
$image = file_get_contents($data);
$fullName = 'images/'.uniqid().time().'.'.pathinfo($data, PATHINFO_EXTENSION);
Storage::disk()->put($fullName, $image);
$image = Image::create([
'url' => Storage::disk()->url($fullName),
]);
return Response::json($image, ResponseHttp::HTTP_CREATED);
}
I have another controller: Profile. When I create a Profile, I want to upload a profile image. How to call function upload from Profile controller and send field image_url?
Here I have Laravel update function,so with this function I update fields and here is imporant input PHOTO
My code is:
public function update($id, Requests\ArticleRequest $request)
{
$this->validate($request, [
'photo' => 'image|max:10000',
// validate also other fields here
]);
// checking file is valid.
if (!$request->file('photo')->isValid()) return redirect()->back()->withErrors(["photo" => "File is corrupt"]);
// file is valid
$destinationPath = public_path().'/images'; // upload path
$extension = $request->file('photo')->getClientOriginalExtension(); // getting image extension
$filename = str_random(5).'.'.$extension; // give a name to the image
$request->file('photo')->move($destinationPath, $filename); // uploading file to given path
// sending back with message
$article = Auth::user()->articles()->findOrFail($id); //if article id is unique just write Article::findOrFail($id)
$article_fields = $request->except('photo');
$article_fields['photo'] = $filename;
$article->update($article_fields);
Alert::message('Your auction is updated', 'Wonderful!');
return redirect('auctions');
}
so when I choose some image to update photo everything is fine,but when I want to update other fileds and photo to stay the same at database... I get error:
Call to a member function isValid() on a non-object
How I can skip photo if $request->file('photo') is blank, so no new image choosen...
public function update($id, Requests\ArticleRequest $request){
**//check if file provided**
if ($request->hasFile('photo')) {
$this->validate($request, [
'photo' => 'image|max:10000',
// validate also other fields here
]);
// checking file is valid.
if (!$request->file('photo')->isValid()) return redirect()->back()->withErrors(["photo" => "File is corrupt"]);
// file is valid
$destinationPath = public_path().'/images'; // upload path
$extension = $request->file('photo')->getClientOriginalExtension(); // getting image extension
$filename = str_random(5).'.'.$extension; // give a name to the image
$request->file('photo')->move($destinationPath, $filename); // uploading file to given path
// sending back with message
$article = Auth::user()->articles()->findOrFail($id); //if article id is unique just write Article::findOrFail($id)
$article_fields = $request->except('photo');
$article_fields['photo'] = $filename;
$article->update($article_fields);
Alert::message('Your auction is updated', 'Wonderful!');
return redirect('auctions');
}
Alert::message('Nothing to update', 'So sad!');
return redirect('auctions');
}
I want to upload a image and change the original name then save it.
Model:
public function rules()
{
return array(
array('image', 'file', 'types'=>'jpg, gif, png'),
);
}
Controller:
$model->image = CUploadedFile::getInstanceByName('image');
If i save it without any other actions it will work.
But how could i change the name of image ? I try something like below:
$model->image->name = "xxx"; //CUploadedFile.name readonly
if($model->save())
$model->images->saveAs(some_path_else.newname); //the files's new name is different from database
$model->image = "abc.jpg"; //wont save it
Is the image attribute must be an instance of CUploadedFile?
Anyone help pls
do something like this
$uploadedFile = CUploadedFile::getInstance($model, 'image');
if (!empty($uploadedFile)) {
//new name will go here
$model->image = strtotime($this->getCurrentDateTime()) . '-' .$uploadedFile;
}
//this will save the image with new name
$uploadedFile->saveAs(Yii::app()->basePath.'/../public/images/user/' . $model->image);
Thanks for your answer.
I figured it out.
CUploadedFile.name is read only , so i can't change it.
The Model need a new public attribute :
public $file;
public function rules()
{
return array(
array('file', 'file', 'types'=>'jpg, gif, png'),
array('iamge', 'length'=>'255'),
);
}
Then in the controller:
$model->file = CUploadedFile::getInstanceByName('image');
$model->file->saveAs(Yii::app()->basePath.'/../public/images/user/' . $model->image);
$model->image = $model->file->name;
It's works fine.(it's not real code)
