Display flags in the language switcher - P1.6, 1.7

Step I - Language Switcher with flags

Take a look into the file. In both Prestashop 1.6 & Prestashop 1.7, you will find something like that:

  <li {if $language.id_lang == $current_language.id_lang} class="current" {/if}>
              <a href="/{url entity='language' id=$language.id_lang}" class="dropdown-item">
                      {$language.name_simple}
             </a>
  </li>

Ok, now we need to add the flag picture. Change it to:

  <li {if $language.id_lang == $current_language.id_lang} class="current" {/if}>
              <a href="/{url entity='language' id=$language.id_lang}" class="dropdown-item">
                   <img src="/img/l/{$language.id_lang}.jpg" alt="{$language.iso_code}" width="16" height="11" />
                   {$language.name_simple}
              </a>
  </li>

You might want to show the flag on current language. Find this code:

  {$current_language.name_simple}
  

Change it to:

  <img src="/img/l/{$current_language.id_lang}.jpg" alt="{$current_language.iso_code}" width="16" height="11" /> 
  {$current_language.name_simple}

The language pictures are located in /your-website/img/l/ folder. Save the changes and enjoy the first step!

Step II - Display inline

In case you want to show the flags inline, open above file, remove everything and paste this source code into it:

<span id="language-selector-label" class="hidden-md-up">{l s='Language:' d='Shop.Theme.Global'}
{foreach from=$languages item=language}
            <a href="/{url entity='language' id=$language.id_lang}" style="margin-right:3px; margin-top: .9375rem;">
                   <img src="/img/l/{$language.id_lang}.jpg" style="{if $language.id_lang == $current_language.id_lang}border:3px solid rgba(0, 0, 0, 0.71);{else}border:3px solid #fff;{/if}" alt="{$language.iso_code}" width="22" height="17" />
           </a>
{/foreach}
