Question

如何在Codeigniter中从倍数复选框获取值并发布数组？我在获取值后数组并回显值时遇到问题。我只看到最后选中的复选框的值。提交时如何显示职位价值？您会找到三个文件：view，Controller和Model。请检查我在哪里错了...

Answer 1

这就是$ menu_links：

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;
}

我编辑了代码以插入新的表单页面，并且需要此页面才能向DB输入一些值。一切正常，它们已插入数据库，只有该复选框不起作用或更好，它仅占用了最后一个选中的复选框的值，而不是所有选中的复选框！我已经尝试了很多方法，但是我不能一个人做。抱歉。

我已经尝试过此代码在您的Page_model中放入此代码。

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;
}
