Question

我想在列表项中添加class =“active”以突出显示所选菜单但我无法弄清楚如何执行此操作，因为我对php并不熟悉。

这就是我在tpl文件中的内容

<ul class="menu">
<li>
    <a<?php echo $target; ?> href="<?php echo $link; ?>"<?php echo $nofollow; ?>><?php echo $this->escape_html($link_title); ?></a>
    <?php echo $sub_menu; ?>
</li>

并在php文件中

        $links = $this->db->GetAll($query);
    foreach($links as $link) {
        $template = $this->PMDR->getNew('Template');
        $template->set('link',$link['url']);
        $template->set('link_title',$link['title']);
        $template->set('nofollow',($link['nofollow'] ? ' rel="'.$link['nofollow'].'"' : ''));
        $template->set('target',($link['target'] ? ' target="'.$link['target'].'"' : ''));
        $template->set('indent',str_repeat('&nbsp;&nbsp;&nbsp;&nbsp;',$level));
        ob_start();
        $this->getMenuLoop($link['id'], $level+1);
        $sub_menu = ob_get_clean();
        if(!empty($sub_menu)) {
            $menu_template = $this->PMDR->getNew('Template',$this->template);
            $menu_template->set('items', $sub_menu);
            $sub_menu = $menu_template->render();
        }
        $template->set('sub_menu', $sub_menu);
        echo $template->render($this->item_template);
    }
}

提前谢谢！

在你的tpl中，添加$class（我把它放在$target，但它可以在<a>内的任何地方）

<ul class="menu">
<li>
    <a<?php echo $target; echo $class; ?> href="<?php echo $link; ?>"<?php echo $nofollow; ?>><?php echo   $this->escape_html($link_title); ?></a>
    <?php echo $sub_menu; ?>
</li>

在你的php文件中添加

$current_url = 'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

AND

$template->set('class',(($current_url == $link['url']) ? ' class="active"' : ''));

检查当前网址是否与$link['url']相同，并添加“class =”active“

    //gets the current page
    $current_url = 'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

    $links = $this->db->GetAll($query);
foreach($links as $link) {
    $template = $this->PMDR->getNew('Template');
    $template->set('link',$link['url']);
    $template->set('link_title',$link['title']);
    $template->set('nofollow',($link['nofollow'] ? ' rel="'.$link['nofollow'].'"' : ''));
    $template->set('target',($link['target'] ? ' target="'.$link['target'].'"' : ''));
    $template->set('class',(($current_url == $link['url']) ? ' class="active"' : ''));
    $template->set('indent',str_repeat('&nbsp;&nbsp;&nbsp;&nbsp;',$level));
    ob_start();
    $this->getMenuLoop($link['id'], $level+1);
    $sub_menu = ob_get_clean();
    if(!empty($sub_menu)) {
        $menu_template = $this->PMDR->getNew('Template',$this->template);
        $menu_template->set('items', $sub_menu);
        $sub_menu = $menu_template->render();
    }
    $template->set('sub_menu', $sub_menu);
    echo $template->render($this->item_template);
}

}
