laravel / php（Crud）将删除按钮连接到功能（路线）

Question

Hi There I have a table that iterates like so

  <form method="get" action="search"> <table class="bordered"> <thead> <tr><th>No.</th><th>Post Username</th><th>Post Title</th><th>Post</th><th>Delete This post</th><td>Update This Post</td></tr> </thead> <tbody> @foreach ($posts as $post) <tr> <td>{{{ $post->id }}}</td> <td>{{{ $post->post_username }}}</td> <td>{{{ $post->post_title }}}</td> <td>{{{ $post->post_message }}}</td> <td> <form method="post" action="{{{ url('delete_post_action') }}}"> <input type="submit" value="{{ $post->id }}">Delete</td> </form> </td> <td><button name="update" value="{{ $post->id }}">Update</button></td> </tr> @endforeach </tbody> </table> </form> 

Which connects to this route.

Route::post('delete_post_action', function()
{
    $sql = "select * from posts";
    $current_posts = DB::select($sql);

    $results=$current_posts;

    return View::make('pages.home')->withposts($results);
});

  function delete_item($id)
  {
    $id = $post->id;
    $sql = "delete from posts where id = ?";
    DB::delete($sql, array($id));
  }

I have no idea why it isn't working. It refreshes the page as intended and updates the table. But it is not deleting any rows!

Concatenate id you are injecting with your query would result in below 

        function delete_item($id)
          {
            $id = $post->id;
            $sql = "delete from posts where id='".$id."'";
            DB::delete($sql);
            return View::make('pages.home')
          }
