How can I tell which page I'm on in the header?

Question

opencart

In the controller->common->header block, I need to determine which page I am currently on, an article, or a product card, or a basket, or a category, etc.
How can I do it?

Answer 1

Under OP 1.5 one could use a construct like:

<?php if (!isset($this->request->get['route'])) {
    $this->request->get['route']='common/home'; // Чтобы не выдавало ошибку, если юзер набрал адрес в браузере руками
  } ?>
  <?php if ($this->request->get['route']=='common/home') { ?>
    <li>
      <a href="/" class="active">Главная</a>
    </li>
  <?php } else { ?>
    <li>
      <a href="/">Главная</a>
    </li>
  <?php } ?>

I pulled from an ancient project where it was necessary to display two different link designs. Under OP2.0, you just need to see how routing is checked.
What version do you have?
