How to check if current static page is frontpage from admin plugin

Question

I set static page as front page.

I need to know if user currently on homepage in my custom plugin.

Functions is_home() and is_front_page() doesn't works, since homepage is static page.

I can get an id of this page :

$frontpage_id = get_option('page_on_front');

But how to get id of current page from admin plugin? (Then i'll be able to compare those ids and detect if current page is homepage!)

2 vancoder Code:

1) Set any static page as frontpage.

2) Create dummy plugin

3) Code of plugin :

$d = is_front_page();
var_dump($d);

==> 

bool(false)

Admin plugin means just plugin :) sorry

And those two lines is all context for now, try it yourself, it doesn't works.

WP version 3.3.2

Answer 1

This is why I asked for more code context. I'll have to guess that you are checking for the front page outside of any hooked function, or inside a function that is called too early, before is_front_page() is ready.

The following will work.

function your_function()  {
$d = is_front_page();
var_dump($d);
}

add_action( 'wp', 'your_function' );

I guess you are talking about the editor screen? If so, you can use the global variable $post_ID:

add_action( 'edit_form_after_title', 'wpse_94626_front_page_detection' );

function wpse_94626_front_page_detection()
{
    global $post_ID, $post_type;

    if ( empty ( $post_ID ) or 'page' !== $post_type )
        return;

    if ( $post_ID === (int) get_option( 'page_on_front' ) )
        print '<p><b>This is the front page!</b></p>';
}
