[Resolved] Change Header logo based on site URL

[Francis]

Hi:
I have one WP site and 3 primary domain names pointing to it.
For domainA.com, I want to display https://domaina.com/wp-content/uploads/01/01/domaina-logo.png as the logo
For domainB.com, I want to display https://domaina.com/wp-content/uploads/01/01/domainb-logo.png as the logo
For domainB.com, I want to display https://domaina.com/wp-content/uploads/01/01/domainc-logo.png as the logo

I have removed the site logo from the Customizer and created a child-theme with the following code in it:

function change_logo_of_site($logo_url){
	$logo_url = $logo_url;
	$home = home_url();
	$home =  $_SERVER['HTTP_REFERER'];
	if($home=='https://domainA.com/'){
		$logo_url = 'https://domaina.com/wp-content/uploads/01/01/domaina-logo.png';
	}
	if($home=='https://domainB.com/'){
		$logo_url = 'https://domaina.com/wp-content/uploads/01/01/domainb-logo.png';
	}
	if($home=='https://domainC.com/'){
		$logo_url = 'https://domaina.com/wp-content/uploads/01/01/domainc-logo.png';
	}
	return $logo_url;
}
add_filter('generate_logo','change_logo_of_site',10,1);

This is not working.
I’ve attempted to place this code into the Appearance > GP Hooks > wp_head area as PHP as well, but no luck.

Can anyone shed light on this for me?

Hi there,

What about this?:

add_filter( 'generate_logo', function( $logo_url ) {
    $home =  $_SERVER['HTTP_HOST'];

    if ( strpos( $home, 'domainA.com') !== false ){
        $logo_url = 'LOGO URL HERE';
    }

    if ( strpos( $home, 'domainB.com') !== false ){
        $logo_url = 'LOGO URL HERE';
    }

    if ( strpos( $home, 'domainC.com') !== false ){
        $logo_url = 'LOGO URL HERE';
    }

    return $logo_url;
} );

Let me know 🙂
