Change the description for username field in user registration

Question

I would like to disable the spaces in the usernames. For that I installed a rules module and i applied a rule. Everything is fine but now the label is still saying : "Spaces are allowed; punctuation is not allowed except for periods, hyphens, apostrophes, and underscores."

How can i change that label ? I looked everywhere and i didn't find a thing.

I am new to drupal. I use drupal 7.

Thanks in advance for you responses.

Answer 1

Another couple of options using string translation techniques:

1. Contrib module: String Overrides
2. settings.php snippet insert

The string overrides module lets you do the string translation via the UI. Otherwise, you can set the override in settings.php - the search string needs to match exactly.

/**
 * String overrides:
 *
 * To override specific strings on your site with or without enabling locale
 * module, add an entry to this list. This functionality allows you to change
 * a small number of your site's default English language interface strings.
 */
$conf['locale_custom_strings_en'][''] = array(
  'Spaces are allowed; punctuation is not allowed except for periods, hyphens, apostrophes, and underscores.' => 'Spaces and punctuation are not allowed except for periods, hyphens, apostrophes, and underscores.',
);

Answer 2

The text is in user_account_form function https://api.drupal.org/api/drupal/modules%21user%21user.module/function/user_account_form/7

To change it, you can implement a hook_form_alter. I believe the text appears on two forms, 'user_register_form' and 'user_profile_form'. Create a module, put this in it (change mymodule to your module name).

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'user_register_form' || $form_id == 'user_profile_form') {
    $form['account']['name']['#description'] = t('This will be the new text Spaces are allowed; punctuation is not allowed except for periods, hyphens, apostrophes, and underscores.');
  }
}
