I've tried to get those checkbox that are unchecked. At this moment i'm just getting those that are checked. Here is my code. That value will be inserted on a table which i don't want to leave it null, that's why i need to get those checkbox unchecked, so that i could insert 1 for checked or 0 for unchecked:

```
  <?php 

    if (!empty($_POST['menu'])) {
    # code...
             foreach ($_POST['menu'] as $value) {
    # code...
              echo "<p>ID Checkbox checked:  ".$value;
             }
    }

   ?>

```

One of the reasons for what i need to get both status: checked or unchecked is because i don't want to leave database fields empty.
