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 file application/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 view application/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. tips:

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', 'aboutme ');

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', 'aboutme '); $ this-> template-> load_main ('about ');
