How it is work?

“Theme and plugin translation for Polylang” automatically searches all files of WordPress themes and plugins. It chooses from this file only those files with extensions:

  • php
  • inc
  • twig

In addition, is implemented the integration with Timber library (read more: http://timber.upstatement.com) – which allows to translate twig’s skins in simple way.
Plugin in searched skins or plugins chooses texts from Polylang functions, such as:

  • _e(string $text, string $domain = ‘default’);
  • __(string $text, string $domain = ‘default’);
  • _x(string $text, string $context, string $domain = ‘default’);
  • pll_e(string $text);
  • pll__(string $text);
  • esc_html(string $text);
  • esc_html_e(string $text, string $domain = ‘default’);
  • esc_html__(string $text, string $domain = ‘default’);
  • _n(string $single, string $plural, int $number, string $domain = ‘default’);
  • esc_attr_e(string $text, string $domain = ‘default’);
  • esc_attr__(string $text, string $domain = ‘default’);

In your function.php, themes or plugins.

For example:

<p><?php pll_e('My text'); ?></p> <p><?php _e('My another text', 'my_theme'); ?></p> 

On the timber context declare this functions like:

$context['pll_e'] = TimberHelper::function_wrapper('pll_e'); $context['pll_'] = TimberHelper::function_wrapper('pll_');

These functions are defined by Polylang plugin for printing translations.
Thanks “Theme and plugin translation for Polylang” you can find these strings to translate and add to Polylang register on very simple way.
And then you can translate these texts from the admin dashboard.
The scan result can be seen on the tab with translations:
