I've done a couple things. One is to use isset() and check first. The other is to add a hidden input field, that way something is always sent.
<input type="hidden" name="test_arr[]"> <input type="checkbox" name="test_arr[]"> <input type="checkbox" name="test_arr[]"> > Best readers, > > //PHP version: 4.3.6 > > I have question concerning the following issue: > > I have a HTML input element of the type check. > > <input type="checkbox" name="test_arr[]"> > > let assum this checkbox is unchecked. The checkbox is part of a form. > Now we gonna submit this form (post) and gonna catch the POST variable > test_arr like this: > > $arr_test = $_POST["test_arr"]; > > This will result in a novice error "Undefined index: " > Of course because test_arr does not exist.
