自定义助手 Codeigniter

Question

您好，目前我只是想出了将视图加载到数组中的方法，但输入的方法很长。

如何最好地创建一个帮助文件/函数，让我仍然可以输入页眉和页脚等并获取视图，但无需我在控制器中输入全长。

目前我必须这样输入

以这种方式工作很长时间

$this->children = array(
   'header' => $this->load->view('theme/default/template/common/header.tpl'),
   'column_left' => $this->load->view('theme/default/template/common/column_left.tpl'),
   'column_right' =>  $this->load->view('theme/default/template/common/column_right.tpl'),
    'content_top' => $this->load->view('theme/default/template/common/content_top.tpl'),
    'content_bottom' => $this->load->view('theme/default/template/common/content_bottom.tpl'),
    'footer' => $this->load->view('theme/default/template/common/footer.tpl')

);

$this->load->view('theme/default/template/common/home.tpl' , $this->children);

我想要一个可以在控制器中调用的帮助文件，所以我只需要输入。如果我不必将完整的视图名称放在帮助器所在的位置，它只会变得更容易

public function index() {

    $this->load->helper('template'); "This is the name I have chosen"

    $this->children = array(
    'header',
    'column_left',
    'column_right',
    'content_top',
    'content_bottom',
    'footer'
    );

    $this->load->view('theme/default/template/common/home.tpl' , $this->children);

}

我认为这应该可行：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

if ( ! function_exists('final_view'))
{
    //$data - CI custom $data (from controller to views)
    //$views - an array with your children views
    function final_view($data, $views = array())
    {
        $CI =& get_instance();
        //Include each views
        foreach($views as $view)
        {
            $CI->load->view('theme/default/template/common/'.$view.'.tpl');
        }

        //Include the main view tpl and the custom CI $data
        $CI->load->view('theme/default/template/common/home.tpl', $data);
    }   
}

编辑：正如 tomexsans 所说，我添加了 CI 实例。

不建议使用助手，因为您将需要 core 函数，只需创建一个新核心并使用它扩展每个控制器

然后您可以执行类似的操作（尚未测试），但它是动态的，允许您始终在代码中使用 header,column_left,column_right,content_top,content_bottom,footer 组合

//param 1 is the config of the view
// param 2 is the data to be passed on the view
function final_view($view,$data)
{   

    //set all path views
    $header['with_stars'] = 'path to view';
    $header['without_bg'] = 'path to view';
    $header['big_title'] = 'path to view';

    $column_left['black'] = 'path to view';
    $column_left['blue'] = 'path to view';
    $column_left['red'] = 'path to view';


    $column_right['big_right'] = 'path to view';
    $column_right['small_right'] = 'path to view';

    $content_top['big_blue_top'] = 'path to view';
    $content_top['small_red_top'] = 'path to view';


    $content_bottom['no_title'] = 'path to view';
    $content_bottom['with_title'] = 'path to view';


    $footer['with_copyright'] = 'path to view';
    $footer['with_big_date'] = 'path to view';


    //combine in one array
    $glue = [
      'header' => $this->load->view($header[$view[0]]),
      'column_left' => $this->load->view($column_left[$view[1]]),
      'column_right' => $this->load->view($column_right[$view[2]]),
      'content_top' => $this->load->view($content_top[$view[3]]),
      'content_bottom' => $this->load->view($content_bottom[$view[4]]),
      'footer' => $this->load->view($footer[$view[5]]),
      'data' => $data
    ];
    // you could do other stuff here before loading the view
    $this->load->view('path_to_view',$glue);
}

您可以这样做，而不是加载视图

//header,column_left,column_right,content_top,content_bottom,footer
$view = array('with_stars','black','big_right','big_blue_top','with_title','with_big_date');
$data['somedata'] = 'data as string';
$data['somedata2'] = array('data as string','some array');

// you could do other stuff here before loading the view
$this->final_view($view,$data);
