如何从复选框中获取值并在codeigniter中发布数组?

How to get value form multiples checkbox and post array in codeigniter? I have problem when I get value post array and echo the value. I see only the value of the last checked checkbox. How to show post value when submit? You find three files: view, Controller and Model. Please check where I wrong...

                </div>
           </div><div class="col-xm-12">
                         <div class="table-responsive">
                             <table class="table table-bordered table-striped" role="grid">

    I have tried this code in your Page_model put this code.

    public function input_values(){
    $checkbox = implode(',', $this->checkBox());
    $data = array(
        'lang_id' => $this->input->post('lang_id', true),
        'title' => $this->input->post('title', true),
        'slug' => $this->input->post('slug', true),
        'page_description' => $this->input->post('page_description', true),
        'page_keywords' => $this->input->post('page_keywords', true),
        'page_content' => $this->input->post('page_content', false),
        'parent_id' => $this->input->post('parent_id', true),
        'page_active' => $this->input->post('page_active', true),
        'title_active' => $this->input->post('title_active', true),
        'breadcrumb_active' => $this->input->post('breadcrumb_active', true),
        'need_auth' => $this->input->post('need_auth', true),
        'howmany_people' => $this->input->post('howmany_people', true),
        'difficulty' => $this->input->post('difficulty', true),
        'howmany_time' => $this->input->post('howmany_time', true),
        'location' => $this->input->post('location', true),
        'subcat_recip_id' => $checkbox
    );
    }
    
    public function checkBox(){
    $count = count($_POST['subcat_recip_id']);
    for($n=0; $n<$count; $n++){
    $checkbox[$n] = $_POST['subcat_recip_id'][$n];
    }
    return $checkbox;
    }
    

    hopefully it helps

    This is what $menu_links is:

    public function get_menu_links_by_lang()
    {
        $lang_id = $this->input->post('lang_id', true);
        if (!empty($lang_id)):
            $menu_links = $this->navigation_model->get_menu_links_by_lang($lang_id);
            foreach ($menu_links as $item):
                if ($item["type"] != "category" && $item["location"] == "header" && $item['parent_id'] == "0"):
                    echo ' <option value="' . $item["id"] . '">' . $item["title"] . '</option>';
                endif;
            endforeach;
        endif;
    }      
    

    I edited a code to insert new form page and I need this page to enter some values into DB. All works Ok and they inserted to DB, only the checkbox doesn't work or better it take only the value of the last checked checkbox and not all the checkbox checked! I have tried it in many ways but I can't do it alone. Sorry.
