Checkbox保持返回true

Question

I have a terms box on my register page, and I am sending that value to a php page where I check the value with the code;

'&terms=' + $("#terms").attr('checked')

and this is the html checkbox:

<input type="checkbox" name="terms" id="terms" data-validate="required"  /> 

In my php, I have tried multiple things, if it's set, if the value is equal to 1 and if it's empty yet my PHP code doesn't run, here's my PHP code:

        $termscheck = isset($_POST['terms']) ? '1' : '';
        if (!$termscheck == 1)
        {
            echo '
                  <div class="col-md-5">
                  <div class="alert alert-danger">
                  <strong>Oh snap!</strong>Must accept terms of service
                  </div>
                  </div>';
            die;
        }

Even when the terms checkbox is and isn't checked that code never runs for some reason. How come?

Answer 1

Use $('#terms').is(':checked') instead of attr
