I got this error
Parse error: syntax error, unexpected '}' in C:\wamp\www\widget_corp\public
\create_subject.php on line 24
when I clicked on my "Creae Subject" button.
I have tried to fix it all day but really can't find what the problem is.

Answer 1

Missing semicolon on the line above the brace.
redirect_to("new_subject.php")
A lot of times you have to look at the line above the one given in the error to see what the problem is.

Answer 2

you have missed semicolon in this line:
redirect_to("new_subject.php");
try this:
if (!empty($errors)) {
$_SESSION["errors"] = $errors;
redirect_to("new_subject.php");
}
