 {{Form::submit('Delete')}}
 {{Form::close()}}
</td>

What you need to do is to set route parameter. Your route should be like that.

 Route::get('post','postController@index');
 Route::get('posts_create',  function (){  return View::make('admin.newPost'); });
 Route::get('posts_show/{id}','postController@show');
 Route::get('posts_edit/{id}','postController@edit');
 Route::post('posts_delete/{id}','postController@destroy');

If you want to use named route {{ Form::open(array('url' => route('posts.edit', $p->id))) }}, you need to set name like that.

 Route::post('posts_edit/{id}', array('uses' => 'postController@edit', 
'as' => 'posts.edit'));

You can check routing in laravel official documentation.

Edit

For now, your form in view look like that.

{{ Form::open(array('url' => route('posts.edit', $post->id), 'method' => 'POST')) }}

In route,

Route::post('posts_edit/{id}', array('uses' => 'postController@edit', 
'as' => 'posts.edit'));

In PostController,

public function edit($id)
{
    // do something
}

I hope it might be useful.
