Load an Include() on first load.

How would I load an Include() ONLY the first time the webpage loads?

I want to use one page for my Template and change the content area with include() statements.

I have set it up so that when you press a nav button on the page that it changes the $content variable HOWEVER, when the page first loads the variable is blank.

So, what I did was establish a base
$content = "homepage.html"

HOWEVER, being the idiot I am sometimes, now the page loads, the "homepage.html" as it should but , when I click a nav button, it will do it again instead of loading the new page. (Obvious since I set the variable to a result, duh)

How do I make the page load the homepage.html Inlcude only on the first visit? I assume a cookie could do it but I've never written a cookie either?

You can check if $content is blank, set it to 'homepage.html'. I.e

if (empty($content)) {
$content = "homepage.html";
}

// ref: http://au2.php.net/manual/en/function.empty.php

// Or
if (!isset($content)){
$content = "homepage.html";
}

// ref: http://au2.php.net/manual/en/function.isset.php

Thanks the isset works better.

Just one more thing.
On the site, I want to have navagation buttons that change the value of $page_content.

How would I set up the link to do that?
A javascript button or would I be able to do it with a <a href> link?

Nevermind.

Figured it out.
