Assuming your data structure (you should update with it):

By id

$my_tag_id = 1;
$my_posts = Post::where('tag_id',$my_tag_id )->get();

By name

$my_tag_name = 'python';
$my_posts = Post::where('tag_id',Tags::where('tag_name',$my_tag_name)->first()->id)->get();

Update with yours relationship and we can get a close approach
