Практика на простой форме PHP и не может понять, почему сообщения об ошибках проверки не появляются, когда поля не заполнены или не выбраны. Может ли кто-нибудь определить, что может вызвать ошибки $, чтобы не показывать? Я не могу сказать, правильно ли работает массив $ errors. Я хотел бы, чтобы каждое сообщение об ошибке появилось под полями, которые не были заполнены, и для полей, которые не очищаются, если, скажем, существует только одна неполная форма.Ошибки проверки формы PHP, не отображающие
Спасибо за любую помощь.

Спасибо, это было полезно - не полностью решена моя проблема (настройка еще одного кода сменила любой выигрыш), но поставил меня на правильный путь. Похоже, что большим фактором были флажки и радиоприемники, которые не устанавливаются, если они не отмечены. Не полностью решить проблему, но попасть туда. –
