Я пытаюсь создать сценарий регистрации PHP, используя подготовленные операторы PDO с позиционными заполнителями. Но запросы MySQL не выполняются. var_dump(); не отображает никаких ошибок.
Мне отчаянно нужно, чтобы кто-то внимательно посмотрел на мой код и объяснил мне, почему запросы не выполняются.
Ниже приведена перезапись register. php, который теперь отображает ошибки, если определенные, предварительно определенные условия не выполняются. Однако при сбое запроса вставки или выбора он не отображает никаких ошибок. var_dump (); также не отображает никаких ошибок, даже если запросы PDO не выполняются.
Пожалуйста, мне нужна ваша помощь, чтобы исправить это. Мы заранее ценим ваше время и вклад. Спасибо.

У меня есть следующий соответствующий код в функциях. php, который вызывается конфигурацией . php:
// validate user input
function student_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
Еще одна вещь: как мне распечатать ошибки в регистрационной форме. php прямо под любым существующим полем ввода ошибки ?
