post the code (html) that creates the checkbox.

[networkthis]

<input type="hidden" name="checkbox[]" value="0" />

 

And the php:

 

elseif ($type == "0") { // hidden checkbox value

 

echo "No checkboxes were checked";

 

}

 

[networkthis]

if(isset($_POST['checkbox1'])) {

echo 'Checkbox 1 was selected'; //Here you do whatever you want to do next.

} else {

echo 'Checkbox 1 was not selected';

}
