validate uploading image on laravel 4 - php

Question

I'm new to Laravel. I have a form with a File upload function on it. How can I validate image file? . when i execute my code the images are getting uploaded but URL is not saved to the MySQL database, and it shows validation errors on the form as follows.
The thumbnail must be an image.
The large image must be an image.
Here's my input and validation code .
{{ Form::open(array('url' => 'admin/templates/save', 'files' => true, 'method' => 'post')) }}
#if($errors->has())
#foreach($errors->all() as $error)
<div data-alert class="alert-box warning round">
{{$error}}
×
</div>
#endforeach
#endif
<div class="row">
<div class="small-5 large-5 column">
{{ Form::label('title','Title:') }}
{{ Form::text('title',Input::old('title')) }}
</div>
</div>
<div class="row">
<div class="small-7 large-7 column">
{{ Form::label('description','Description:') }}
{{ Form::textarea('description',Input::old('description'),['rows'=>5]) }}
</div>
</div>

$template->save();
return Redirect::back()->with('success', 'Template added!');

Move your upload code inside validation passes
public function saveTemplate() {
//TODO - Validation
$rules = [
'title' => 'required',
'description' => 'required',
'detailed_description' => 'required',
'targeturl' => 'required',
'thumbnail' => 'required|image',
'large_image' => 'required|image'
];
$validator = Validator::make(Input::all(), $rules);
if ($validator->passes()) {
$thumb = Input::file('thumbnail');
$destinationThumb = public_path().'/thumb/';
$thumbname = str_random(6) . '_' . $thumb->getClientOriginalName();
$uploadSuccess = $thumb->move($destinationThumb, $thumbname);
$file = Input::file('large_image');
$destinationPath = public_path().'/img/';
$filename = str_random(6) . '_' . $file->getClientOriginalName();
$uploadSuccess = $file->move($destinationPath, $filename);
$template = new Template();
$template->title = Input::get('title');
$template->description = Input::get('description');
$template->thunbnailURL = $destinationThumb . $thumbname;
$template->detailedDescription = Input::get('detailed_description');
$template->targetURL = Input::get('targeturl');
$template->detailImageURL = $destinationPath . $filename;
//$user->created_at = DB::raw('NOW()');
//$user->updated_at = DB::raw('NOW()');
$template->save();
return Redirect::back()->with('success', 'Template added!');
} else
return Redirect::back()->withErrors($validator)->withInput();
}
