Excellent! Been receiving this error in VS 2008 ever since I updated to IE9.
Was becoming a real pain!

Haha Jon, I’ve done that before. Given an answer then said, “I mean, the opposite!” I got a puzzled look, as if you say, “I’ll give you that–maybe.”

Phil, Dody, you’re both right. Defining the constant would fix the problem. However, I was looking for Jon’s answer. HIDE_NAV is undefined, but why is that a problem? Undefined variables get evaluated as false. Constants, however, get interpreted as strings.

BTW, a couple blatantly wrong answers would be someone scratching their head and saying, “But … HIDE_NAV isn’t defined — that should error!” Or worse yet would be someone responding, “The navigation didn’t get displayed because getNav() wasn’t defined till after it was called!

But yes, Jon hit it right on, and it would be a great chance for him to top it off with any other useful details about how strings or constants or variables work and really stand out from the rest.

For example, what does an undefined variable really equal? It’s not false. Is it null? What does isset() check? That a variable is defined or that a variable is not null? Etc.

I’ll try to post another slightly harder question in a few days!

Because HIDE_NAV is not defined.
Now give me a new job

The simple answer, “define( ‘HIDE_NAV’, false );” between lines 1 and 7 in home.php or between lines 1 and 4 in skin.php.

I’ll e-mail the more elegant design on request.

(not to mention, depending on your PHP version / distro, adding ‘php’ to the end of line 1 in each file)

Actually, that was exactly backwards logic…

if ( !defined( 'HIDE_NAV' ) || !constant( 'HIDE_NAV' ) )

HIDE_NAV is interpreted as a string value, and therefore is never false but always true. Instead: if ( defined( 'HIDE_NAV' ) && constant( 'HIDE_NAV' ) )
