```
<input name="inform_me" id="inform_me" type="checkbox"> inform me

```

Whenever I check if this checkbox is set, I get 

> 
> bool(true)
> 
> 
> 

even if the checkbox is not really checked. 

This is how my PHP looks like:

```
var_dump(isset($_POST['inform_me']));

```

What's wrong with it?
