Php 代码点火器防止重复数据

我有一个具有2个功能的控制器：

图像

录像带

我已经创建了一个

页眉

和

页脚

模板来加载我的视图，我想将css样式表设置为用户首选的设置“亮”或“暗”。例如，用户将他们的主题设置为暗，我想用dark.css更新

标题

视图，但我目前正在重复我的代码，我想防止出现这种情况。我不得不这样做两次。一次用于图像：

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);

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);      

有更多的代码，所以我没有将两者结合起来。我只显示部分代码

是否有人可以指导我如何整合代码的正确方向？

如果代码中有

elseif

块，那么也没有用，如果您提取公共数据以通过数据传递，这是我可以想到的一种最小化尝试

若要应用此功能，请从代码中删除

if

、

elseif

和

else

块并放置

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";

如果要使其更通用，请在同一控制器中创建函数

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";
}

并用一行代码替换我答案中显示的第一个代码块

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

您将在

$data

中定义这五个变量，谢谢！如果我希望这适用于我的所有观点，我该怎么做？我不想每次在控制器中添加带有视图的新函数时都添加这个。太棒了！我要试试这个。它奏效了！我会接受这个答案。这可以变成一个库吗？这样我就不必在每个控制器中创建这个函数，而只需加载库？我想我回答了我自己的问题。谢谢或者，您可以在助手中复制相同的函数，并通过

apply（$data，$user\u data->style）调用，这将更可取
