Image in Laravel 5 is not working - php

Question

I am working with image in Laravel 5. I use folklore package of Laravel 5. it works fine for store but shows problem while updating image.
ArticleController:
$article_to_update = $article->find($id);
$uploaded_image = $request->file('image_file');
$parameter = $request->all();
if (isset($uploaded_image))
{
$ext = $uploaded_image->getClientOriginalExtension();
$newImageName = $article_to_update->id . "." . $ext;
$uploaded_image->move(
base_path() . '/public/uploads/article/', $newImageName
);
Image::make(base_path() . '/public/uploads/article/' . $newImageName, array(
'width' => 170,
'height' => 120,
))->save(base_path() . '/public/uploads/article/' . $newImageName);
$parameter = $request->all();
$parameter['image'] = $newImageName;
unset($parameter['image_file']);
$article_to_update->update($parameter);
} else
{
$article_to_update->update($parameter);
}
Session::flash('message', 'The article was successfully edited!.');
Session::flash('flash_type', 'alert-success');
return redirect('articles');
}
Edit.blade.php:
<div class="form-group">
<label><b>IMAGE</b></label>
{!! Form::file('image_file',null,array('class'=>'form-control','id'=>'file_uploader')) !!}
{!! Form::text('image',null,array('class'=>'form-control','id'=> 'file-name')) !!}
</div>
Model:
<?php namespace App;
use Illuminate\Database\Eloquent\Model;
use \App\Auth;
/**
* Class Article
* #package App
*/
class Article extends Model {
/**
* #var array
*/
protected $guarded = [];
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function tags()
{
return $this->belongsToMany('App\Tag');
}
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function category()
{
return $this->belongsTo('App\Category');
}
}
problem shows when i put a image too in the field..
Column not found: 1054 Unknown column 'image_file' in 'field list'
(SQL: update `articles` set `updated_at` = 2015-08-20 07:15:14,
`image_file` = afc-logo.gif where `id` = 457)
Anyone help?

Answer 1

The above code was not working because in edit form, encrypt/multipart is not used for image or any file..
so I used file=true that solved my problem..
{!! Form::model($article,['method' => 'PATCH','route'=> ['articles.update',$article->id],'files' => true]) !!}
This solves the whole updating image problem...
