CodeIgniter template engine uses instance _ php instance

This article describes how to use the CodeIgniter template engine. For more information, see I. Example:

Codeigniter is usually used for loading:

$this->load->view('about', $data);

Through this class library, you can load a view into this template:

$this->template->load('template', 'about', $data);

Load view about. php to the template file.

Ii. Installation

Download ci_template_library.zip
Decompress the package and put Template. php In the application/libraries application class library directory;
Automatically load application/config/autoload. php when the application starts;

3. Create a template fileApplication/views/template. php
The code in the template is as follows:

  
<?= $contents ?>
  
Copyright 2008

$ Contents shows the content to be inserted in the controller.

4. Create a viewApplication/views/about. php
Add the following code:

About
I'm so human!

Load view in template engine
Can be used in your Controller

$this->template->load('template', 'about');

Workflow of this template engine:

The view is loaded into a variable, which is loaded into the template.

var $template_data = array(); function set($name, $value){ $this->template_data[$name] = $value;} function load($template = '', $view = '' , $view_data = array(), $return = FALSE){         $this->CI =& get_instance(); $this->set('contents', $this->CI->load->view($view, $view_data, TRUE));  return $this->CI->load->view($template, $this->template_data, $return);}

5. Skills Summary:

Tip 1: simple short tag in the template

Example: If you need to display the title on the page.
Add the following in the HTML header views/template. php:

  <?= $title ?>

Then, directly set in the controller:

$this->template->set('title', 'About me');

Tip 2: highlight the current navigation

Navigation is usually used in a template. A good experience navigation should tell the user what the current location category is.

Define your navigation project:

Introduce application/libraries/Template. php and add the following to the Controller:

$this->set('nav_list', array('Home', 'Photos', 'About', 'Contact'));

Update your template:

Add the following in application/views/template. php:

 
 

  
   <?php foreach($nav_list as $i => $nav_item): ?> 
  
  
 <?= anchor($nav_item, $nav_item) ?> 
 <?php endforeach ?>
 
 

The anchor function is used here. You need to add the related Assistant to the automatic loading Configuration:

$autoload['helper'] = array('url');

Update your controller:

Added:

$this->template->set('nav', 'About');

Note:
1. If all navigation is in a controller, you can add General navigation code to the destructor;
2. Define the style of the current navigation, for example: # navigation. selected

Advanced Tip 3: Multiple templates

The simplest way to process multiple templates is to define multiple new methods in libraries/Template. php to replace existing content. The second advanced technique is to use a custom method:

function load_main($view = '', $view_data = array(), $return = FALSE){ $this->set('nav_list', array('Home', 'Photos', 'About', 'Contact')); $this->load('template', $view, $view_data, $return);}

Paste the code into the Controller

$this->template->set('nav', 'About');$this->template->set('title', 'About me');$this->template->load_main('about');
