PHP, если еще проблема обнаружена

Question

Я пытаюсь создать if else строки на php из PrestaShop,

Я пытаюсь сделать мой сайт, чтобы запустить код, если страница скидка, но запустить другой код, если это не ... но мечтатель говорит, что есть ошибки, что в этом плохого?

Спасибо

это код

if ($page_name == 'discount') 
{ 
public static $definition = array(
    'table' => 'address', 
    'primary' => 'id_address',

Вы не можете определить публичный статический член, как это. Вы объявляете его в классе, а затем инициализируете его в методе:

class X {

      $definition = array (
          'table' => 'address', 
          'primary' => 'id_address', 
          'fields' => array (
