How can I confirm I'm on the home page

Question

I have the index.php in themes directory as my homepage. How can I confirm programmatically that the homepage was called in my functions.php? is_home() and is_front_page() is true for other pages and PHP_SELF always shows index.php.

[More info]

What I'm trying to do is show some Google Web Optimizer Control scripts only on the home page (http://example.com/). The B in the A/B test is index-3 (http://example.com/index-3). But what happens is that if I hit our blog pages (http://example.com/blogs) is_home() and is_front_page() is triggering true causing the script to show in the head. I'm not sure what is causing the blogs page to trigger. I'm using the wp_print_scripts event to trigger my function in the functions.php file.

Settings>>Reading is set to "Your latest posts" the home page name is index.php located in the themes directory.

So the final question is "Is there a method to know that the function called is for the home page (http://example.com/) and not another?"

Answer 1

If you are using the default home page, which in most cases is a list of most recent posts, is_home() should work.

If you have set a static page to be your front page (in Settings >> Reading), is_front_page() should work. If you are not getting the results you expect using this:

if (is_front_page()) {
  //the code you want to execute
}

perhaps you can describe your situation in more detail.

Up-voted @supertrue, but wanted to add some clarification:

• is_front_page() returns true when on the site front page (what is commonly referred to as the "home" page).
• is_front_page() returns true when on the site front page, whether the front page is set to display the Blog Posts Index or a static Page.
• is_home() returns true when displaying the Blog Posts Index.
• is_home() returns true when displaying the Blog Posts Index, whether on the Front Page, or on a static Page.
• A useful option for differentiating between static Page and Blog Posts Index when on the Front Page is get_option( 'show_on_front' ), which returns either page or posts

EDIT

Settings>>Reading is set to "Your latest posts" the home page name is index.php located in the themes directory.

So, based on what I stated above:

• When on the Front Page, then is_front_page() always returns true.
• When displaying your Blog Posts Index ("your latest posts"), is_home() always returns true.

Your Front Page is set to display your blog posts index, thus both is_front_page() and is_home() will return true.

Yes! That's what is_front_page() is for.

If you need to know you're on the front page, and that the front page is static:

if ( is_front_page() && 'page' == get_option( 'show_on_front' ) )

If you need to know you're on the front page, and that the front page is your blog posts:

if ( is_front_page() && 'posts' == get_option( 'show_on_front' ) )
