I'm trying to change a label of Drupal 8's contact form ('Your email address'). The label is defined /core/modules/contact/src/MessageForm.php, but obviously I don't want to change this in core.

$form['mail'] = array(
'#type' => 'email',
'#title' => $this->t('Your email address'),
'#required' => TRUE,

In Drupal 7 I always used string overrides but the module isn't available for Drupal 8 yet. How can string be overridden in Drupal 8?

    It looks like there is a usable version of this module for Drupal 8, according to this post from a year ago: drupal.org/node/2236791

  • @Kevin Thanks. Looks like it isn't even alpha though - will try the custom method first.

  • This is an example of a question where we may have a duplicate already for how to override a string.

The easiest method would be to implement a hook_form_alter inside a custom module that overrides the title


Some information how to create custom module.

    This hook can also be used from the theme layer, too.

  • Thanks... and ouch, that's complicated. Lots of reading on creating custom modules to do...

You can always override strings in settings.php like this:

$settings['locale_custom_strings_en'][''] = array(
  'Related entities for @group' => 'Add Content to group @group',

You can change en to de or whatever two letter language code you like.

Please note: the entire string must exist by itself. For example, the above string override existed in the group module controller like this:

return $this->t('Related entities for @group', ['@group' => $group->label()]);

This will NOT work:

$settings['locale_custom_strings_en'][''] = array(
  'Related entities for ' => 'Add Content to ',

So for the example listed in the question, you could use:

$settings['locale_custom_strings_en'][''] = array(
  'Your email address' => 'Your email ID',
  • Yep, sometimes it is much easy just to add override for core string or config
