Anchor setup wih a php echo

Hello!

I know how do anchors in general but when it comes to links like this:

<a href="addEdit.php?id=<?php echo $row['id']; ?>" class="btn btn-warning">edit</a>

or

 <a href="postAction.php?action_type=delete&id=<?php echo $row['id']; ?>" class="btn btn-danger" onclick="return confirm('Are you sure to delete data?')?true:false;">delete</a>

how do I setup the anchor so it connects correctly? I dont see an example in the CI tutorial. Thank you so very much!!
