In this article we will try to describe how to change default logo into 3 different logos for user who use WPML. We will try to do it for 3 languages:

• English


• Italian


• German

1. Please find wp-content/themes/myhome/includes/menu/class-myhome-menu.php file

2. Please backup the file

3. Please edit the file

4. Find logo code in this file:

<?php if ( ! empty( $logo ) ) : ?>
   <a class="logo_link" href="<?php echo esc_url( $homepage_url ); ?>"
      title="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>">
                <img
      src="<?php echo esc_url( $logo ); ?>"
      data-logo="<?php echo esc_url( $logo ); ?>"
                 <?php if ( ! empty( $logo_when ) ) : ?>
         data-logo-switch="<?php echo esc_url( $logo_when ); ?>"
                 <?php endif; ?>
      alt="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>"
   >
            </a>
<?php endif; ?>

Change it into this example: 

<style>
    .logo_link--white {
        display:none!important;
    }

    .mh-header--transparent .logo_link--white {
        display:block!important;
    }

    .mh-header--transparent .logo_link--dark {
        display:none!important;
    }
</style>

<?php if (ICL_LANGUAGE_CODE == 'en'): ?>
    <a class="logo_link logo_link--white" href="http://link-to-english-version-of-the-homepage.com">
        <img src="http://link-to-english-logo-white-version">
    </a>
    <a class="logo_link logo_link--dark" href="http://link-to-english-version-of-the-homepage.com">
        <img src="http://link-to-english-logo-dark-version">
    </a>
<?php endif; ?>

<?php if (ICL_LANGUAGE_CODE == 'de'): ?>
    <a class="logo_link logo_link--white" href="http://link-to-german-version-of-the-homepage.com">
        <img src="http://link-to-german-logo-white-version">
    </a>
    <a class="logo_link logo_link--dark" href="http://link-to-german-version-of-the-homepage.com">
        <img src="http://link-to-german-logo-dark-version">
    </a>
<?php endif; ?>

<?php if (ICL_LANGUAGE_CODE == 'it'): ?>
    <a class="logo_link logo_link--white" href="http://link-to-italian-version-of-the-homepage.com">
        <img src="http://link-to-italian-logo-white-version">
    </a>
    <a class="logo_link logo_link--dark" href="http://link-to-italian-version-of-the-homepage.com">
        <img src="http://link-to-italian-logo-dark-version">
    </a>
<?php endif; ?>

Please change language codes for your own and point links to your logos image files (e.g. jpg / png). There are 2 version of logo for each language, because menu need one additional logo for transparent menu.

 Please remember to put good version of protocol (http or https)
