Explanation

Want to add a language switcher to your WordPress site using a shortcode? Here's a simple way to do it with the Polylang plugin.

What This Does:

  • Creates a shortcode [wp_dudecom_language_switcher] that you can place in posts, pages, or widgets.
  • Displays a language switcher if the Polylang plugin is active.
  • Shows a message if Polylang isn't active, reminding you to activate it.

How It Works:

  • The code checks if Polylang is active using function_exists('pll_the_languages').
  • If active, it uses Polylang's function to display the language switcher.
  • It also adds custom styles for the switcher from a CSS file in your theme's directory.

What You Need:

  • Ensure the Polylang plugin is installed and activated.
  • Create a CSS file named language-switcher.css in your theme's css folder for styling.

Simply use the shortcode [wp_dudecom_language_switcher] wherever you want the language switcher to appear on your site. Easy peasy!
