My controller code for upload file in laravel 5.4:
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 :
FileNotFoundException in MimeTypeGuesser.php line 123
The file is there any fault in my code or is it a bug in laravel 5.4, can anyone help me solve the problem ?
My view code:
<form enctype="multipart/form-data" method="post" action="{{url('admin/post/insert')}}">
{{ csrf_field() }}
<div class="form-group">
<label for="imageInput">File input</label>
<input data-preview="#preview" name="input_img" type="file" id="imageInput">
<img class="col-sm-6" id="preview" src="">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="form-group">
<label for="">submit</label>
<input class="form-control" type="submit">
</div>
</form>
Try this code. This will solve your problem.
public function fileUpload(Request $request) {
$this->validate($request, [
'input_img' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
if ($request->hasFile('input_img')) {
$image = $request->file('input_img');
$name = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/images');
$image->move($destinationPath, $name);
$this->save();
return back()->with('success','Image Upload successfully');
}
}
You can use it by easy way, through store method in your controller
like the below
First, we must create a form with file input to let us upload our file.
{{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.
<?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 $photoName to the database as a user_photo field value. You can use asset(‘avatars’) function in your view and access the photos.
Use the following code:
$imageName = time().'.'.$request->input_img->getClientOriginalExtension();
$request->input_img->move(public_path('fotoupload'), $imageName);
A good logic for your application could be something like:
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 library http://image.intervention.io/
This library provides a lot of useful features:
Basic Examples
// 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:
$img = Image::make('public/foo.jpg')->resize(320, 240)->insert('public/watermark.png');
Tips: (In your case) https://laracasts.com/discuss/channels/laravel/file-upload-isvalid-returns-false
Tips 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:
$this->validate($request, [
'input_img' =>
'required
|image
|mimes:jpeg,png,jpg,gif,svg
|max:1024',
]);
Function:
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
$image->save(); //
}
}
if ($request->hasFile('input_img')) {
if($request->file('input_img')->isValid()) {
try {
$file = $request->file('input_img');
$name = time() . '.' . $file->getClientOriginalExtension();
$request->file('input_img')->move("fotoupload", $name);
} catch (Illuminate\Filesystem\FileNotFoundException $e) {
}
}
}

https://laracasts.com/discuss/channels/laravel/image-upload-file-does-not-working
or
https://laracasts.com/series/whats-new-in-laravel-5-3/episodes/12
i think better to do this
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 images is folder that laravel make it automatic and file is 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
// get image from upload-image page
public function postUplodeImage(Request $request)
{
$this->validate($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
$getimageName = time().'.'.$request->uplode_image_file->getClientOriginalExtension();
$request->uplode_image_file->move(public_path('images'), $getimageName);
return back()
->with('success','images Has been You uploaded successfully.')
->with('image',$getimageName);
}
In Laravel 5.4, you can use guessClientExtension
