I've had sites where I've organized this file by alphabetical button-name (as indicated in your example, above) and other sites where it made more sense to organize the file by page, as below. It all depends on which way you (or whoever is going to maintain the list) find it easier to locate/verify that all the title-text values are supplied.
Code:
define ('CSS_BUTTON_POPUPS_IS_ARRAY', 'true');
define ('CSSBUTTONS_CATALOG_POPUPS_SHOW_BUTTON_NAMES_TEXT', ': No title defined; see ' . __FILE__);
$css_button_text = array ();
switch ($current_page_base) {
case FILENAME_ACCOUNT_EDIT:
case FILENAME_ACCOUNT_HISTORY:
case FILENAME_ACCOUNT_NEWSLETTERS:
case FILENAME_ACCOUNT_NOTIFICATIONS:
case FILENAME_ACCOUNT_PASSWORD:
$css_button_text['button_back'] = 'Return to <em>Manage Your Account</em>';
$css_button_text['button_forward'] = 'Go somewhere else';
break;
case FILENAME_ADDRESS_BOOK_PROCESS:
$css_button_text['button_back'] = 'Return to your <em>Address Book</em>';
break;
default:
$css_button_text['button_back'] = 'Return to the previous page';
$css_button_text['button_forward'] = 'Go to the next page';
break;
}
