Codeigniter 防止重复数据

Question

我有一个具有 2 个功能的控制器：

1. 图片
2. 视频

我创建了一个 header 和 footer 模板来加载我的视图，我想将 css 样式表设置为用户首选设置“浅色”或“深色”。因此，例如，用户将他们的主题设置为深色我想用 dark.css 更新 header 视图，但我目前正在重复我的代码，我想阻止这种情况。我必须这样做两次。图片一次：

public function images() 
{
    //is the user logged in? if not redirect to login page
    if ( ! $this->my_auth->logged_in())
    {
      redirect('auth/login', 'refresh');
    }

    //set the view data
    $data['title'] = 'Upload Images | My Idea Cloud';
    $data['heading'] = 'Upload Images';
    $data['attributes'] = array(
      'class' => 'dropzone',
      'id' => 'image-dropzone'                
    );

    // get users style and set the correct style sheet
    $user_data = $this->my_auth->user()->row();

    if ($user_data->style == 'light')
    {
        $data['flat_css'] = 'flat-ui-light.css';
        $data['navbar_class'] = 'navbar-default';
        $data['footer_class'] = 'bottom-menu-default';
        $data['custom_css'] = 'custom-light.css';
        $data['dropzone_css'] = 'dropzone-light.css';
    }
    elseif ($user_data->style == 'dark')
    {
        $data['flat_css'] = 'flat-ui-dark.css';
        $data['navbar_class'] = 'navbar-inverse';
        $data['footer_class'] = 'bottom-menu-inverse';
        $data['custom_css'] = 'custom-dark.css';
        $data['dropzone_css'] = 'dropzone-dark.css';
    }
    else
    {
        $data['flat_css'] = 'flat-ui-dark.css';
        $data['navbar_class'] = 'navbar-inverse';
        $data['footer_class'] = 'bottom-menu-inverse';
        $data['custom_css'] = 'custom-dark.css';
        $data['dropzone_css'] = 'dropzone-dark.css';
    }


    //load the views    
    $this->load->view('templates/frontend/front_header', $data);
    $this->load->view('templates/frontend/front_navbar');
    $this->load->view('frontend/upload_images', $data);
    $this->load->view('templates/frontend/front_footer', $data);

还有一次用于视频功能

public function videos() 
{
    if ( ! $this->my_auth->logged_in())
    {
      redirect('auth/login', 'refresh');
    }

    $data['title'] = 'Upload Videos| My Idea Cloud';
    $data['heading'] = 'Upload Videos';
    $data['attributes'] = array(
      'class' => 'dropzone',
      'id' => 'video-dropzone'                
    );

    // get users style and set the correct style sheet
    $user_data = $this->my_auth->user()->row();

    if ($user_data->style == 'light')
    {
        $data['flat_css'] = 'flat-ui-light.css';
        $data['navbar_class'] = 'navbar-default';
        $data['footer_class'] = 'bottom-menu-default';
        $data['custom_css'] = 'custom-light.css';
        $data['dropzone_css'] = 'dropzone-light.css';
    }
    elseif ($user_data->style == 'dark')
    {
        $data['flat_css'] = 'flat-ui-dark.css';
        $data['navbar_class'] = 'navbar-inverse';
        $data['footer_class'] = 'bottom-menu-inverse';
        $data['custom_css'] = 'custom-dark.css';
        $data['dropzone_css'] = 'dropzone-dark.css';
    }
    else
    {
        $data['flat_css'] = 'flat-ui-dark.css';
        $data['navbar_class'] = 'navbar-inverse';
        $data['footer_class'] = 'bottom-menu-inverse';
        $data['custom_css'] = 'custom-dark.css';
        $data['dropzone_css'] = 'dropzone-dark.css';
    }

    $this->load->view('templates/frontend/front_header', $data);
    $this->load->view('templates/frontend/front_navbar');
    $this->load->view('frontend/upload_videos', $data);
    $this->load->view('templates/frontend/front_footer', $data);      

代码更多，所以我没有将两者结合起来。我只显示部分代码。

有人可以指导我如何整合我的代码吗？

Answer 1

您的代码中没有使用elseif 块，如果您提取公共数据以通过数据传递，这是我能想到的一种最小化尝试。

要应用此功能，请从您的代码中删除 if、elseif 和 else 块并放入，

if($user_data->style == 'light')
{
    $intensity = 'light';
    $default = 'default';
}
else
{
    $intensity = 'dark';
    $default = 'inverse';
}

$data['flat_css']     = "flat-ui-{$intensity}.css";
$data['navbar_class'] = "navbar-{$default}";
$data['footer_class'] = "bottom-menu-{$default}";
$data['custom_css']   = "custom-{$intensity}.css";
$data['dropzone_css'] = "dropzone-{$intensity}.css";

如果你想让它更通用，在同一个控制器中创建一个函数，

function apply(&$data,$style)
{
    if($style == 'light')
    {
        $intensity = 'light';
        $default = 'default';
    }
    else
    {
        $intensity = 'dark';
        $default = 'inverse';
    }

    $data['flat_css']     = "flat-ui-{$intensity}.css";
    $data['navbar_class'] = "navbar-{$default}";
    $data['footer_class'] = "bottom-menu-{$default}";
    $data['custom_css']   = "custom-{$intensity}.css";
    $data['dropzone_css'] = "dropzone-{$intensity}.css";
}

并将我的答案中显示的第一个代码块替换为一行

$this->apply($data,$user_data->style);

你会得到$data中定义的这五个变量
