How to import/add translated strings having inline styles?

Question

I've imported a .po file having Spanish translations. The import was successful but some translation strings were skipped because they contain disallowed HTML.

From UI, I found that some translations were not translated. So I tried them adding those via the translate admin interface (Administration » Configuration » Regional and language » Translate interface)

I could see the original text having inline style like following.

But when I tried to add a Spanish (Latin American) Translation and hit 'Save translations' getting the following error.

The submitted string contains disallowed HTML:<span style="color:#0098CF">Hola</span>

I've enabled Translatable all HTML text formats under multilingual settings (Administration » Configuration » Regional and language » Multilingual settings)

It's working when I remove inline style add translation like the following. So I guess it's not supporting inline styles and classes.

<span> Hola </span>

What could be the problem? I found a function in function locale_string_is_safe($string) under includes/locale.inc file. Do I need to do any tweaks with that?

Any suggestions would be much appreciated.

Answer 1

Yes your guess is correct,locale_string_is_safe "Check that a string is safe to be added or imported as a translation." if you want to ignore your job you should patch it for a while , change it to

function locale_string_is_safe($string) {
  return TRUE:
}

after your job revert it.

Here's an alternative without hacking the core. You simply could unset the validation for the translation interface form:

/**
 * Implements hook_form_alter().
 */
function MYMODULE_form_alter(&$form, &$form_state, $form_id) {

  // That's the form ID of the translation interface.
  if ($form_id == 'i18n_string_locale_translate_edit_form') {

    // Let's check at least for a user's role first.
    global $user;
    if (in_array('administrator', $user->roles)) {

      // Simply unset the validation. Done.
      unset($form['#validate']);
    }
  }
}
