Php 从数据库Codeigniter创建下拉菜单

我正在尝试创建下拉菜单。 数据库表：

*cat*

catid, catname, catsex

*menus*

id,parrentid,name,icon,slug,number

视图中的菜单代码

echo $this->multi_menu->render(array(

        'nav_tag_open'        => '<ul class="nav nav-pills">',    

        'parentl1_tag_open'   => '<li class="dropdown">',

        'parentl1_anchor'     => '<a tabindex="0" data-toggle="dropdown" href="%s">%s<span class="caret"></span></a>',

        'parent_tag_open'     => '<li class="dropdown-submenu">',

        'parent_anchor'       => '<a href="%s" data-toggle="dropdown">%s</a>',
        'children_tag_open'   => '<ul class="dropdown-menu">',
        'item_active'         => 'Gallery/foto'
    )); 

模型库中的菜单代码\u模型

public function every()
    {
        return $this->db->get("menus")
                    ->result_array();
    }

现在我将试着解释我的问题是什么。 我想创建一个下拉菜单项，其中显示所有猫的名字（我想从数据库表中获取这些名字），若我在数据库中更改了任何猫的名字记录，那个么它也应该在菜单项中更改。诸如此类

Cats Female
Adorada Amor
Dani Vitala

Cats Male
Glant Diamo
Lorris Diatore
Paol Duece

其中名称来自数据库表cat。 有什么帮助吗？

你可以这样试试

在控制器中：

public function abc()
    {
        $data['plan_data']=$this->plan_model->view_plan();

        $this->load->view('templates/header',$header);
        $this->load->view('xyz',$data);
        $this->load->view('templates/footer');
    }

public function view_plan()
{
        $sql="SELECT * FROM your table";
        $query = $this->db->query($sql);
        return $query->result_array();
    }

<select class="form-control" name="plan_type" required>
                                <option value="">--- Select ---</option>
                                <?php
                                foreach ($plan_data as $plan){
                                    if($plan['plan_id']==$select_plan){
