یکی چیزی بگه؟؟؟

[mtchabok]

سلام عزیز
این ارور واسه متدی هس که حق دسترسیش protected هس یعنی اینکه در خارج شیی بهش دسترسی نداریم ...
برای اینکه کمکتون کنیم کدهای کلاس CI_Upload رو واسمون بزارید .

[MMSHFE]

با سلام، همونطور كه دوستمون گفتن، مشكل از protected بودن عنصر موردنظر در كلاس CI_Upload هست. درنتيجه فقط توي كلاسهاي مشتق شده از اين كلاس بهش دسترسي دارين نه ازطريق اشياء ايجادشده از اون. يا روش كارتون رو عوض كنيد، يا اينكه اون عنصر رو public كنيد (روش اول توصيه ميشه).
موفق باشيد.
