How to replace all spaces with underscores as a result of views output in a text field?

Question

Drupal

How to replace all spaces with underscores as a result of views output in a text field? Probably you can create a field template, but maybe there is another way? Thank you.

Answer 1

Something like this:

function YOU_MODULE_NAME_preprocess_views_view_field(&$vars) {
  $view = $vars['view'];
  $field = $vars['field'];

  if ($view->name == 'name' && $view->current_display == 'display' && $field->field_alias == 'alias') {
    $vars['output'] = str_replace(' ', '_', $vars['output']);
  }
}

Be careful with $field->field_alias if the code above does not work, it's most likely that you did not specify it correctly.
