Validation Error for feedback Text area

1 New Member

Heyy guys, Im a total newbie to php and have begun learning it.
I was creating a Php form for name and feedback in which I have put some validation conditions for name and feedback,like if they are empty it should display empty.But somehow its only displaying it for name and not for feedback.Can you please find any mistake in my code so that I can proceed further.Thanks for the help.

your textarea contains a line break, which doesn’t count as empty.

second, do away with the test_input() function. it creates context changes where no context change exists. and its name is also misleading.
