Answer 1

Suppose this is your checkbox: <input type="checkbox" name="uid" value="some_value">

you can use below code to check whether this checkbox is checked or not:

 <?php
  echo (isset($_POST['uid'])?$_POST['uid']:'');
 ?>

isset($_POST['uid']) will check whether its checked or not, and therefore $_POST['uid'] will return its value if checked.

Answer 2

So I think what you want to do is this though. If I understand it correctly.

<input type="checkbox" name="UUID[]" value="<?echo $row['UUID'];?>">

Now when you post the page you will have an array called UUID in the POST with each UUID selected.
