推荐答案
您的都是缺失值，因此$ _POST ['waiver']将始终为空。修正这样：
Your waiver radio inputs are both missing values, so $_POST['waiver'] will always be empty. Fix like this:
<input type="radio" name="waiver" value="yes">
<input type="radio" name="waiver" value="no">
您的复选框字段可以设置这样的变量（只要检查是否设置）：
Your checkbox fields can set the variables like this (just check if set):
$jesse_van_anterp_huyck_scholarship = isset($_POST["jesse_van_anterp_huyck_scholarship"]) ? 1 : 0;
FYI：您的varchar（30）字段可能不足以存储字符串Jesse Van Anterp惠氏奖学金
FYI: Your varchar(30) fields may not be long enough to store strings like "Jesse Van Anterp Huyck Scholarship"
