Что приводит к тому, что текстовые значения пустые при отправке на db

Question

Я добавляю форму и скрипт, который обрабатывает загрузку файла изображения. Я добавил текстовые поля, переключатель и дополнительную загрузку файлов.

Загрузка изображения и дополнительная часть загрузки файла в скрипт работают нормально, также как и переключатель. Эти значения сохраняются в моем sql db правильно.

Однако все текстовые поля отправляют пустые значения в sql.

Вот сценарий до моего оператора SQL, который помнит, работает для URL-адреса изображения, документирует значение переключателя. Но все текстовые поля, такие как «title» и «address», пусты в базе данных.

Answer 1

Если вы выполнения mysql_code внутри класса CropAvatar тогда ваши переменные из сферы класса. Кажется, вы не показываете весь ваш PHP-код (не хватает некоторых закрывающих тегов), поэтому я не могу быть уверен.
