This conditional statement doesn't look logic to me.

While watching the video, at 1:53, Zac tells that the conditional if statement, simply checks if this page is the home page AND the front page, if so, the following code is executed, if not, the code inside the else statement is executed.

That's not difficult to understand but to me, the if conditional statement checks if we are indeed on the home page and NOT the front page, as we have an exclamation mark just in front the is_front_page() function...

What am I' missing here please ? Can someone enlight me...

Here is the code that I'm pointing out:

<?php if ( is_home() &&  ! is_front_page() ) : ?>
         //execute some code

I guess is_home returns true as we are on the home page, the is_front_page() function is according to the codex, a boolean function as well, returning TRUE when the main blog page is displayed. To me, It sounds like that's the case here. So the code shouldn't be displayed as TRUE && FALSE => is FALSE.

I guess my lack of understanding comes from the fact the home page isn't a blog page, so is_front_page() returns false, but with the preceeding exclamation mark, It becomes true and then the code inside the if statement gets executed...

What I think is confusing everyone (including me) is Zac says, "OR" when the operator is clearly an "AND".

The line of code is checking to see if it is on the Home page AND IS NOT the Front Page, which makes no sense.

Could Zac Gordon please help to clarify this?

Thanks. :)

I still don't get it, I'm sorry...

<?php if ( is_home() &&  ! is_front_page() ) : ?>
         //execute some code

Why does Zac say in the video about this line above:

if It's the home OR frontpage then output this...

To me this piece of code means: If you are on the home page AND NOT on the front_page then...

I'm confused.

the naming conventions of WordPress mean that front_page.php will be the home page of your website if that exists.

if you choose to have your blog as the home page, you could use home.php, or even default back up the template hierarchy to index.php - in which case the home page would not be front page.

omg you are right it is an AND and there is no logic now xD. But that isn't a simple AND, theres a exclamation character "&& !" So it makes sense :)

It's simple doublecheck about if some piece of code is at the homepage of site.

geoffrey I was wondering the same thing. The code makes no sense. If it is_home, but not the front_page is what I am reading..
