Upload files or images in laravel 5:-

It’s easy to working with files or images in laravel 5. we can easily validate and upload files in laravel 5. laravel 5 have it’s own functions to make files upload easy and fast. i am sharing some code to upload image in laravel 5 or any of files type. it’s also easy to validate file types.

1. create a form with attribute ‘files’=>true or try below code (in my case i haveresources/views/pages/upload.blade.php) :-

<div class="about-section">
   <div class="text-content">
     <div class="span7 offset1">
        @if(Session::has('success'))
          <div class="alert-box success">
          <h2>{!! Session::get('success') !!}</h2>
          </div>
        @endif
        <div class="secure">Upload form</div>
        {!! Form::open(array('url'=>'apply/upload','method'=>'POST', 'files'=>true)) !!}
         <div class="control-group">
          <div class="controls">
          {!! Form::file('image') !!}
	  <p class="errors">{!!$errors->first('image')!!}</p>
	@if(Session::has('error'))
	<p class="errors">{!! Session::get('error') !!}</p>
	@endif
        </div>
        </div>
        <div id="success"> </div>
      {!! Form::submit('Submit', array('class'=>'send-btn')) !!}
      {!! Form::close() !!}
      </div>
   </div>
</div>

2. create a controller and add below function (in my case i have ApplyController):-

<?php namespace App\Http\Controllers;
use Input;
use Validator;
use Redirect;
use Request;
use Session;
class ApplyController extends Controller {
public function upload() {
  // getting all of the post data
  $file = array('image' => Input::file('image'));
  // setting up rules
  $rules = array('image' => 'required',); //mimes:jpeg,bmp,png and for max size max:10000
  // doing the validation, passing post data, rules and the messages
  $validator = Validator::make($file, $rules);
  if ($validator->fails()) {
    // send back to the page with the input data and errors
    return Redirect::to('upload')->withInput()->withErrors($validator);
  }
  else {
    // checking file is valid.
    if (Input::file('image')->isValid()) {
      $destinationPath = 'uploads'; // upload path
      $extension = Input::file('image')->getClientOriginalExtension(); // getting image extension
      $fileName = rand(11111,99999).'.'.$extension; // renameing image
      Input::file('image')->move($destinationPath, $fileName); // uploading file to given path
      // sending back with message
      Session::flash('success', 'Upload successfully'); 
      return Redirect::to('upload');
    }
    else {
      // sending back with error message.
      Session::flash('error', 'uploaded file is not valid');
      return Redirect::to('upload');
    }
  }
}
}

3. setting up routes :-

Route::get('upload', function() {
  return View::make('pages.upload');
});
Route::post('apply/upload', 'ApplyController@upload');
