Question

我的控制器是

[code]$data['navlist'] = $this->MCats->getCategoriesNav();[/code]

模型是

[code]
    function getCategoriesNav(){
        $data = array();
        $this->db->group_by('parentid', 'id');
        $Q = $this->db->get('categories');
        if($Q->num_rows >0){
            foreach($Q->result() as $row){
                if($row->parentid > 0){
                    $data[0][$row->parentid]['children'][$row->id] = $row->name;
                }else{
                $data[0][$row->id]['name'] = $row->name;
                }
            }
        }
        $Q->free_result();
        return $data;
    }
[/code]

和观点是

[code]if(count($navlist)){
    echo "<ul>";
    foreach($navlist as $key => $list){
        foreach($list as $topkey => $toplist){
            echo "<li class='cat'>";
            echo anchor("welcome/cat/$topkey", $toplist);
            echo "</li>\n";
            if(count($toplist['children'])){
            foreach($toplist['children'] as $subkey => $subname){
                echo "\n<li class='subcat'>";
                echo anchor("welcome/cat/$subkey", $subname);
                echo "</li>";
                }
            }
        }

    }
    echo "</ul>\n";

}[/code]

看起来你在两个不同地方使用的$ data [0]应该是$ data，而是将所有循环db结果加载到一个数组键中，键0
