Notes about WordPress and WPML:

Once installed wordpress and wpml, we can activate the translation of strings, if our subject is properly adjusted, in the files of the subject appearing chains type:

<?php _e('NIF', 'afegit'); ?>
<?php __('NIF', 'afegit'); ?>

in this case “Afegit” will be the domain of WPML string translation within WPML –> Themes and Plugins, we will have to check for new translations (first image), if we modify the theme files or add new fields to which we add translation functionality
