WordPress Change logo image when I click to a different language

Question

I have a multilingual website. Is there a way I can change the logo.png to a different .png after I switch to \"India\"? I am using polylang plugin

Answer 1

function pojo_polylang_get_multilang_logo( $value ) {
if ( function_exists( 'pll_current_language' ) ) {
    $logos = array(
        'en' => 'logo-en.png',
        'in' => 'logo-in.png',
    );
    $default_logo = $logos['en'];
    $current_lang = pll_current_language();
    $assets_url = get_stylesheet_directory_uri() . '/assets/images/';
    if ( isset( $logos[ $current_lang ] ) )
        $value = $assets_url . $logos[ $current_lang ];
    else
        $value = $assets_url . $default_logo;
}
return $value;
}
add_filter( 'theme_mod_image_logo', 'pojo_polylang_get_multilang_logo' );

if you have a look from $assets_url to $return $value you will see an if statement :

        $assets_url = get_stylesheet_directory_uri() . '/assets/images/';
    if ( isset( $logos[ $current_lang ] ) )
        $value = $assets_url . $logos[ $current_lang ];
    else
        $value = $assets_url . $default_logo;
}
return $value

from what I am looking at I can see an error as the if statement does not include {} maybe if you changed it to the following it might work?

        $assets_url = get_stylesheet_directory_uri() . '/assets/images/';
    if ( isset( $logos[ $current_lang ] ) ) {
        $value = $assets_url . $logos[ $current_lang ];
    } else {
        $value = $assets_url . $default_logo;
    }
}
return $value
