Deleting files that belong to a post? - laravel

Question

I have two tables called 'posts' and 'photos'. The 'photos' table store the images for the 'post'. A post can have many photos so the relationship is one-to-many. I've managed to create the store method, I already create the view to show a post with its photos as well. Below is the function :
public function show($titleslug) {
$post = Post::where('titleslug', '=', $titleslug)->first();
$images = $post->photos;
return view('dashboard/posts/show', compact('post','images', $post, $images));
}
The show view :
<div class="contentpanel">
<div class="row blog-content">
<div class="col-sm-12">
<div class="panel panel-default panel-blog">
<div class="panel-body">
<div class="panel-body">
<h3 class="blogsingle-title">{{$post->title}}</h3>
<ul class="blog-meta">
<li><i class="fa fa-clock-o"></i> Jan 02, 2014</li>
</ul>
<div class="mb20"></div>
{!! $post->content !!}
</div><!-- panel-body -->
<div class="mb20"></div>
</div><!-- panel-body -->
</div><!-- panel -->
</div><!-- col-sm-8 -->
</div><!-- row -->
<div class="row blog-content">
<div class="col-sm-12">
<div class="panel panel-default panel-blog">
<div class="panel-body">
<h3 class="blogsingle-title">This post featured images :</h3>
<div class="mb20"></div>
<?php foreach ($images as $i): ?>
<div class="col-xs-12 col-sm-4 col-md-3">
<div class="blog-item">
<img src="{{asset('image/'. $i->image)}}" class="img-responsive" alt="" style="height: 150px;"/>
<div class="blog-details">
<ul class="blog-meta">
<li><a class="btn btn-sm btn-warning" title="Edit" href="#"><i class="fa fa-edit"></i></a></li>
<form action="#" method="POST">
<input type="hidden" name="_method" value="DELETE">
<input type="hidden" name="_token" value="{{ csrf_token() }}" />
<li>
<button type="submit" class="btn btn-sm btn-danger" title="Delete" onclick="return confirm('Are you sure deleting this photo ?');"><i class="fa fa-trash-o"></i></button>
</li>
</form>
</ul>
</div>
</div><!-- blog-item -->
</div><!-- col-xs-6 -->
<?php endforeach; ?>
</div>
<div class="panel-body">
<div class="alert alert-info fade in">
<p>
<button type="button" class="btn btn-info">Add New Images</button>
</p>
</div>
</div>
</div><!-- panel -->
</div>
</div>
</div><!-- contentpanel -->
I want to be able to delete the images from the show view, how to do that ? Do I need to create a function to it ? If so, then how will the function looks like ?
That's all and thanks, sorry for asking too much

Answer 1

First, edit your delete form in the view by adding :
...
<input type="hidden" name="image_id" value="{{ $images->id }}" /> // Assuming that photo id is in your $images object
...
Then, you could create a POST route image/delete associated to delete function from your controller to remove the expected image :
public function delete() {
$image_id = $request->only('image_id');
$image = Photo::where('id', '=', $image_id)->delete(); // Assuming that you have a Photo model
return view('dashboard/posts/show');
}
