each language with its own logo in the header

Hoi Victoria,

Thank you for your advice. But what is not quite clear to me: Which function.php do I have to adapt now?
/wp-content/themes/enfold-child/functions.php (because I use enfold-child)
/wp-content/themes/enfold/functions.php
/wp-content/themes/enfold/functions-enfold.php

The directory for the logos is, I think at least, this one:
/wp-content/themes/enfold/images/layout

For this reason I also adjusted the path for the logos in the script accordingly:

function pojo_polylang_get_multilang_logo( $value ) {
if ( function_exists( ‘pll_current_language’ ) ) {
$logos = array(
‘de_CH’ => ‘Logo_DE.png’,
‘fr_FR’ => ‘Logo_FR.png’,
);
$default_logo = $logos[‘en’];
$current_lang = pll_current_language();
$assets_url = get_stylesheet_directory_uri() . ‘/images/layout/’;
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’ );

Thank you very much for your help!

Best regards,
Esther
