php - 如何在 PrestaShop 的 .tpl 文件中创建全局变量？

Question

我想创建一个全局变量，它将在 .tpl 文件中设置和获取。应该为用户(登录或未登录)保存全局变量

Answer 1

在 Override -> classes -> controller -> FrontController.php 中创建了一个覆盖

并添加代码:

<?php

use PrestaShop\PrestaShop\Adapter\Cart\CartPresenter;
use PrestaShop\PrestaShop\Adapter\ObjectPresenter;
use PrestaShop\PrestaShop\Adapter\Configuration as ConfigurationAdapter;
use PrestaShop\PrestaShop\Adapter\Image\ImageRetriever;
use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Debug\Debug;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\Config\FileLocator;

class FrontController extends FrontControllerCore
{
    public function initContent()
    {
        $this->context->smarty->assign(array(
            'VARIABLE_NAME' => VARIABLE_VALUE,
        ));
        return parent::initContent();
    }
}
?>
