Question

我只是想知道实现菜单，页眉和页脚的最佳方式/做法，包括更改内容，例如使用codeigniter的通知。

例如说我在标题菜单中有一个警报链接回数据库中的数据，我需要在每次加载页面时检查更改。最初我以为我每次都可以使用$ this-＆gt; load-＆gt; view（'header'）调用标题，但这意味着我需要一个全局函数来计算警报的任何更改，然后将其传递给标题视图，每次都不好！

我想我需要一种全局方式来调用函数，该函数从任何控制器加载网站标题（菜单），该控制器计算内容并相应地显示视图。

所以例如显示博客页面的控制器在您的控制器构造函数中 - 定义您的博客视图文件所在的文件夹和模板名称

// the folder your content files are in 
$this->templatefolder = 'blog' ;
// the template name
$this->view_template = 'blog_template' ;

在准备调用某些视图的方法中

$data['content01'] = 'search_articles';
$data['content02'] = 'main_article';
$data['content03'] = 'suggested_articles';
$this->load->view( $this->view_template, $data );

模板本身 views / blog_template.php

// opening html etc that is generic to website
$this->load->view('tmpl_open');

// so if the header has to be dynamic
// get the header from a model (or library etc) 
// and either pass the header content or just echo it out directly 
$this->load->model('header');

if( ! $newHeader = $this->header->returnNewHeader() )
{

  // fallback if the header doesn't come back from the model 
  $this->load->view('default_header');

} 
else
{   echo $newHeader ;     } 

// this is optional but IF the template folder is not set 
// we have a default folder called 'pages' to look in for the content views 

// but in this example the folder is set to be 'blog' 
// so the blog view files will be in application/views/blog/search_articles.php etc etc
if( isset($this->templatefolder)){

$templatefolder = $this->templatefolder . '/' ;  }

else { $templatefolder = 'pages/'; }

// header that is specific for the content 
$this->load->view($templatefolder . 'header');

// so in this specific example its going to load 3 view files, but this part is completely flexible 
if(isset($content01))
$this->load->view($templatefolder.$content01);

if(isset($content02))
$this->load->view($templatefolder.$content02);

if(isset($content03))
$this->load->view($templatefolder.$content03);

if(isset($content04))
$this->load->view($templatefolder.$content04);

if(isset($content05))
$this->load->view($templatefolder.$content05);

if(isset($content06))
$this->load->view($templatefolder.$content06);

if(isset($content07))
$this->load->view($templatefolder.$content07);

if(isset($content08))
$this->load->view($templatefolder.$content08);

// example of an optional file that you can uncomment for testing 
// $this->load->view('objecttesting');

// bottom nav bar generic to website
$this->load->view('tmpl_footer');

// closing html etc generic to website
$this->load->view('tmpl_close');
