类别与每个类别与 Codeigniter 中的复选框的兼容性

Question

我有一个化学品类别，需要检查每个类别的化学品与自己和他人的兼容性。带有复选框的循环内的循环。 1.通过javascript点击隐藏元素无法设置值； 2. 当 24 个类别的数据达到 14000 多个奇数条目时，我如何进行和优化。 3. 建议使用逗号分隔值或单独条目？ 4. 如何在同一页面

上从数据库表中获取数据时编辑记录并保持复选框处于选中状态

代码如下：

控制器

public function compactibility_chart_master(){
    $data['title'] = 'Compactibility Chart Master';
    $this->form_validation->set_rules('category[]', 'Category Name','required|trim|xss_clean');
    if($this->form_validation->run() === FALSE){
        $data['category'] = $this->admin_model->get_all_active_entities('tbl_category');
        $this->load->view('admin/compactibility_chart_master',$data);
    }else{
        $this->admin_model->set_compactibility_chart_master();
        $this->session->set_flashdata('success','Compacitibiliy Chart Master updated Successfully');
        redirect('compactibility_chart_master', 'refresh');
    }
}

型号

public function set_compactibility_chart_master(){
    $post = $this->_array_remove_null($this->input->post());
    $insertdata = array();
    for($z=0;$z<count($post['cat_cat']);$z++){
        foreach($post['cat_cat'] as $values){
            $insertdata[] = array(
                'category'          => $post['category'][$z],
                'category_compact'  => $values,
            );
        }
    }
    $this->db->insert_batch('tbl_compactibility_master',$insertdata);
    return true;
}

Answer 1

将复选框值存储在具有唯一ID的单独表中将复选框中的ID值设置为值并将字段名称显示为标签

因为将来在某些情况下您必须更改复选框名称，以便您可以轻松更改特定的 id 行数据。当您尝试使用逗号分隔符保存时，这是不可能的。

我在这里找到了一种方法。希望它可以帮助某人。谢谢
