Joomla：显示菜单项的页面标题

Question

如果已填充，我想显示 Joomla 菜单项的页面标题。 我试过这段代码没有成功：

<h1 class="title">
    <?php
        if (null === ($this->params->get('page_heading')))
        {
            $mydoc = JFactory::getDocument();
            $mytitle = $mydoc->getTitle();
            echo $mytitle;
        }
        else 
        {
            $active = JFactory::getApplication()->getMenu()->getActive();
            echo $active->params->get('page_heading');
        }
    ?>
</h1>

有什么建议吗？

Answer 1

我已经这样解决了自己：

<h1 class="title">
    <?php $menu  = JFactory::getApplication()->getMenu();
        $active = $menu->getActive();
        $mydoc = JFactory::getDocument();
        $mytitle = $mydoc->getTitle();
        $pageHeading = $active->params->get('page_heading');
        if($pageHeading != "")
        {
            echo $pageHeading;
        }
        else 
        {
            echo $mytitle;
        }
    ?>
</h1>

Answer 2

我有类似的需求，并注意到此代码在 Joomla 4 中不起作用。这是我的解决方案：

Joomla 3

$menu = JFactory::getApplication()->getMenu()->getActive();
$title = $menu->title;
$page_heading = $menu->params->get('page_heading');
echo $page_heading ?? $title;

Joomla 4

$menu = JFactory::getApplication()->getMenu()->getActive();
$title = $menu->title;
$page_heading = $menu->getParams()->get('page_heading');
echo $page_heading ?? $title;

这两者之间的唯一区别是如何获取菜单项params ，J3 中的参数与 J4 中的getParams() 。
