Can't upload photo in Laravel 4 - php

Question

I'm trying to add some products to my database and I have to upload photo of this product. I've made a controller and view but when I click Create I don't have any errors but I don't have photo too. I want to upload only jpg,jpeg,gif,png files how can I do it? Here is my code:
Controller:
public function postAddProduct(){
$destinationPath = '';
$filename = '';
$newId = Product::max('id')+1;
$validator = Validator::make(Input::all(), array(
'name' => 'required',
'description' => 'required',
'partner_link' => 'required',
'image' => 'required'
));
if (Input::hasFile('image')) {
$file = Input::file('image');
$destinationPath = public_path().'/uploads/products/';
$filename = $newId.'.'.$file->getClientOriginalExtension();
$uploadSuccess = $file->move($destinationPath, $filename);
}
if($validator->passes()){
$product = new Product;
$product->name = Input::get('name');
$product->description = Input::get('description');
$product->category_id = Input::get('category');
$product->partner_link = Input::get('partner_link');
$product->photo = $filename;
$product->save();
return Redirect::back();
}else{
return Redirect::back()->withErrors($validator)->withInput();
}
}
View:
{{ Form::open(array('url'=>'user/admin/products/addd', 'class'=>'col-md-4', 'style'=> 'float:none; margin: 0 auto', 'id'=>'register-form')) }}
<h2 class="form-signin-heading">Add Product</h2>
{{ Form::text('name', null, array('class'=>'form-control', 'placeholder'=>'Name')) }}
{{ Form::text('description', null, array('class'=>'form-control', 'placeholder'=>'Description')) }}
{{ Form::text('partner_link', null, array('class'=>'form-control', 'placeholder'=>'Partner link')) }}
{{Form::label('category', 'Category: ', array('class' => 'field-name'))}}
<select name="category">
<?php $i = 0; ?>
#foreach($categories as $category)
<optgroup label="{{$category['name']}}">
#foreach($category['subcategories'] as $sub)
<option value="{{$sub->id}}">{{$sub->name}}</option>
#endforeach
</optgroup>
#endforeach
</select>
<div class="clearfix"></div>
{{Form::file('image', array('style' => 'margin-bottom: 10px'))}}
{{ Form::submit('Save', array('class'=>'btn btn-large btn-primary btn-block'))}}
{{ Form::close() }}

You form should have option 'files' set to 'true':
{{ Form::open(array('url' => 'foo/bar', 'files' => true)) }}
