Translate Plugin From Child Theme - ever needed to translate some strings from a plugin so as to be able to further upgrade the main plugin without loosing your translations?

translate_plugin_from_child_theme.php

<?php
add_action( 'after_setup_theme', 'load_custom_translations');
function load_custom_translations(){
	load_child_theme_textdomain( 'woocommerce-bookings', get_stylesheet_directory() . '/translations' );
	load_child_theme_textdomain( 'woocommerce-social-login', get_stylesheet_directory() . '/translations' );
}

add_filter( 'load_textdomain_mofile', 'filter_custom_translation_paths', 10, 2);
/**
 * Update the path for loading custom translations for plugins
 * @param $mofile Original mo file;
 * @param $domain The plugin domain
 *
 * @return mixed The new filtered path
 */
function filter_custom_translation_paths($mofile, $domain) {
	// If the mofile to be translated is not our default child theme file
	if (false === strpos($mofile, '/wp-content/themes/my_theme/translations/ro_RO.mo')) {
		return $mofile;
	}
	else {
		return trailingslashit(dirname( $mofile )) . $domain . '-' . basename( $mofile );
	}
}

This helped me. Thanks :)
