# 🪐 orbit-compat-polylang — Polylang compatibility Polylang is the open-source WPML alternative (~700K sites). Different API than WPML — both must be supported separately, since users pick one based on price/preference. --- ## What this skill checks ### 1. Register translatable strings ```php // Register on init add_action( 'init', function() { if ( function_exists( 'pll_register_string' ) ) { pll_register_string( 'welcome_text', 'Welcome to my plugin', 'My Plugin', false ); } } ); // Retrieve $translated = function_exists( 'pll__' ) ? pll__( 'Welcome to my plugin' ) : 'Welcome to my plugin'; ``` ### 2. Current language ```php $lang = function_exists( 'pll_current_language' ) ? pll_current_language() : 'en'; ``` ### 3.

Custom post type registration **Whitepaper intent:** Polylang reads CPT settings — your plugin should register CPTs with `'show_in_rest' => true` AND let Polylang's settings UI mark them translatable. ```php register_post_type( 'my_plugin_post', [ 'public' => true, 'show_in_rest' => true, // Polylang admin → Languages → Settings → Custom post types and Taxonomies // user enables "translate" for this CPT ] ); ``` ### 5. Detect active ```php if ( function_exists( 'pll_register_string' ) || class_exists( 'Polylang' ) ) { // Polylang is active } ``` ### 6. URL handling (3 URL modes like WPML) ```ph
