drupal confirm_password field set description under both textboxes in drupal

i have an confirm password field in the drupal and i need to set description for both the text boxes and i tried this.

$form['pass[pass1]']['#description'] = 'textbox开发者_C百科1';
$form['pass[pass2]']['#description'] = 'textbox2';

is that possible . can any one please explain how to do it .

i tried this too.

   $form['pass']['pass1']['#description'] = 'textbox1';
    $form['pass']['pass2']['#description'] = 'textbox2';

for both code nothing changes in the gui

The password field gets split into two in the expand_password_confirm function (called pass1 and pass2 like you've got above so I guess you probably already know that). You can probably change the descriptions in a form pre render function, so in your form put:

$form['#pre_render'] = array('MYMODULE_my_form_pre_render');

And then create the following function:

function MYMODULE_my_form_pre_render(&$form) {
  $form['pass']['pass1']['#description'] = 'textbox1';
  $form['pass']['pass2']['#description'] = 'textbox2';
}

Hope that helps
