Question

有人可以告诉我如何在prestashop 1.6中的TopColumn中显示标签吗？我知道我必须编辑blogtags.php，但我不知道该怎么做 - 我的PHP太弱了。

当然我试过 - 现在我可以在管理面板中挂钩标签，但不能在网站上挂钩。我做了什么？

function install()
    {
        $success = (parent::install() && $this->registerHook('header') && **$this->registerHook('displayTopColumn')** && Configuration::updateValue('BLOCKTAGS_NBR', 10));

        if ($success)

public function hookdisplayTop($params)
    {
        return $this->hookdisplayTopColumn($params);
    }

改变这个：

public function hookdisplayTop($params)
{
    return $this->hookdisplayTopColumn($params);
}

对此：

public function hookdisplayTopColumn($params)
{
    return $this->hookLeftColumn($params);
}
