Мой Character.php

    $buttons = ""; 
    $empty = true; 

    $characters = $_handlerGameServer->fetch($_queryGame['characters'],array($session->get("account")));

    if (!$empty)

?> 

Answer 1

Если функция возвращает ложь или пустой, вероятно, можно сделать:

if($characters = $_handlerGameServer->fetch($_queryGame['characters'],array($session->get("account")))) { 

    foreach ($characters as $character) { 
     $buttons .= "<button class='buttonProcess' name='select_character' title='character_id' value='".$character[0]."'>".$character[1]."</button>\n"; 
    } 

    $_templatePage->replace("buttons",$buttons); 
} else { 
    $_templatePage->replace("buttons",$_lang['error']['noCharacters']."<br /><a href='?page=select_server' class='linkProcess' name='unset_server'>".$_lang['character']['changeServer']."</a> | <a href='?page=account' class='linkProcess' name='logout'>".$_lang['character']['logout']."</a> "); 
}
