add_action( 'user_new_form', 'change_label_form' );
function change_label_form() {
echo '<script>
jQuery(document).ready(function($) {
$("label[for=email]").html("Example");
} );
</script>';
}
here is trick worked for me , you can change the label for any filed by using the for tag in the label and you can add action on any form you like, as
add_action( 'edit_user_profile_update', 'change_label_form' );
Here is another trick you can use
add_action('admin_head-user-edit.php', 'setup_user_edit');
function setup_user_edit() {
add_filter('gettext', 'change_profile_labels');
}
function change_profile_labels($input) {
if ('Email' == $input)
return 'Example';
return $input;
}
