从多维数组中创建面包屑

Question

在我之前的问题中，我错误地认为只有一个[sub]键，但整个侧边栏菜单是这样的:

$sidebar = array(
    'dashboard' => array(
        'levels' => array('1', '2'),
        'title' => 'Bacheca',
        'icon' => 'fa-dashboard',
        'url' => '/ctrl/dashboard',
    ),
    'settings' => array(
        'levels' => array('1'),
        'title' => 'Impostazioni',
        'icon' => 'fa-gear',
        'sub' => array(
            'configuration' => array(
                'levels' => array('1'),
                'title' => 'Configurazione',
                'url' => '/ctrl/configuration',
            ),
            'languages' => array(
                'levels' => array('1'),
                'title' => 'Lingue',

        ),
    ),

        'levels' => array('1'),
        'title' => 'Utenti',
        'icon' => 'fa-users',
        'sub' => array(
            'customers' => array(
                'levels' => array('1'),
                'title' => 'Clienti',
                'url' => '/ctrl/customers',
            ),
            'agents' => array(
                'levels' => array('1'),
                'title' => 'Agenti',
                'url' => '/ctrl/agents',
            ),
        ),
    ),
);

可以看到，[sub] s可以嵌套
问题仍然是:给定与上面示例中的url之一匹配的字符串，我想使用title s

构建面包屑

。e，给定字符串/ctrl/booking/prices/，我想得到以下列表(然后我可以用CSS转换为面包屑):

预订
2. 关税分配
3. Modifica Prezzi

(你看我在数组中向后查找标题;注意最后一项链接到url)

请帮忙?

Answer 1

我编辑了你的答案:

function getTitle(Array $arr, $find, $firstLevel = true) {
    $resultArray = array();
    foreach($arr as $val){
        if (isset($val['url']) && $val['url'] == $find) {
            return array('<li><a href="' . $val['url'] . '">' . $val['title'] . '</a></li>');
        }
        if (isset($val['sub'])) {
            $result = getTitle( $val['sub'], $find, false);
            if($result){
                $resultArray = array_merge($result);
                $resultArray[] = '<li>' . $val['title'] . '</li>';
                if(!$firstLevel){
                    return $resultArray;
                }
            }
        }
    }
    if(count($resultArray)){
        return implode(array_reverse($resultArray));
    }
    return false;
};

使用示例:

echo getTitle($sidebar, '/ctrl/booking/prices');

结果

:

预订

关税分配

Modifica Prezzi

用法示例2:

echo getTitle($sidebar, '/ctrl/categories');

结果2 :

Impostazioni

Categorie
