TinyButStrong template engine in Kohana PHP framework

styczeń 9, 2008 | 17:11

It took me a while to set up a TinuButStrong template engine into Kohana. I hope, this post will help You do it faster. You will need at least revision 1690 of Kohana (it didn’t worked for me with stable release). You can download it manually from their SVN/Trac or build rpm package from kohana.spec on DEVEL branch for PLD-Linux.

You will need to add some files to Your application/ dir.

libraries/MY_Controller.php:

PLAIN TEXT
PHP:
  1. <?php defined(‘SYSPATH’) or die(‘No direct script access.’);
  2.  
  3. class Controller extends Controller_Core
  4. {
  5.         function __construct()
  6.         {
  7.                 parent::__construct();
  8.         }
  9.  
  10.         public function _kohana_load_view($template, $vars)
  11.         {
  12.                 if ($template == ”)
  13.                         return;
  14.  
  15.                 if (substr(strrchr($template, ‘.’), 1) === “html”)
  16.                 {
  17.                         $this->tbs->LoadTemplate($template);
  18.                         if (is_array($vars) && count($vars)> 0)
  19.                         {
  20.                                 foreach ($vars as $key => $val)
  21.                                 {
  22.                                         if(is_array($val))
  23.                                         {
  24.                                                 $this->tbs->MergeBlock($val[‘name’], $val[‘data’]);
  25.                                         }
  26.                                         else
  27.                                         {
  28.                                                 $this->tbs->MergeField($key, $val);
  29.                                         }
  30.                                 }
  31.                         }
  32.  
  33.                         $output = $this->tbs->Show(TBS_NOTHING);
  34.                 }
  35.                 else
  36.                 {
  37.                         $output = parent::_kohana_load_view($template, $vars);
  38.                 }
  39.  
  40.                 return $output;
  41.         }
  42. }

libraries/MY_View.php:

PLAIN TEXT
PHP:
  1. <?php
  2. defined(‘SYSPATH’) or die(‘No direct script access.’);
  3.  
  4. class View extends View_Core
  5. {
  6.         public function __construct($name, $data = NULL, $type = NULL)
  7.         {
  8.                 $name .= “.html” . $type;
  9.  
  10.                 if (!Kohana::find_file(‘views’, $name, TRUE, TRUE))
  11.                 {
  12.                         $type = Null;
  13.                 }
  14.  
  15.         parent::__construct($name, $data, $type);
  16.         }
  17. }

libraries/Tbs.php (the file is almost same like TBS_Wrapper for CodeIgniter):

PLAIN TEXT
PHP:
  1. <?php defined(‘SYSPATH’) or die(‘No direct script access.’);
  2.  
  3. require_once(“tbs_class_php5.php”);
  4.  
  5. class Tbs_Core
  6. {
  7.         private static $TBS = null;
  8.  
  9.         public function __construct()
  10.         {
  11.                 if(self::$TBS == null) $this->TBS = new clsTinyButStrong();
  12.         }
  13.  
  14.         public function LoadTemplate($File, $HtmlCharSet=‘UTF-8′)
  15.         {
  16.                 return $this->TBS->LoadTemplate($File, $HtmlCharSet);
  17.         }
  18.  
  19.         public function MergeBlock($BlockName, $Source)
  20.         {
  21.                 return $this->TBS->MergeBlock($BlockName, $Source);
  22.         }
  23.  
  24.         public function MergeField($BaseName, $X)
  25.         {
  26.                 return $this->TBS->MergeField($BaseName, $X);
  27.         }
  28.  
  29.         public function Show()
  30.         {
  31.                 $this->TBS->Show(TBS_NOTHING);
  32.                 return $this->TBS->Source;
  33.         }
  34. }







Additionally, upload the tbs_class_php5.php file into libraries/ too. You can also upload it to vendors/ dir and load it using Kohana loader classes.
You can autoload it in config/config.php by adding tbs into the autoload property:

PLAIN TEXT
PHP:
  1. $config[‘autoload’] = array
  2. (
  3.         ‘libraries’ => ‘tbs, session, database’
  4. )

If $data array would contain another array, it will be processed with MergeBlock(), otherwise it will be MergeFielded().
Now, You’re ready to use it with Your app.
controllers/module.php:

PLAIN TEXT
PHP:
  1. <?php defined(‘SYSPATH’) or die(‘No direct script access.’);
  2.  
  3. class Module_Controller extends Controller
  4. {
  5.         function index()
  6.         {
  7.                 $this->load->model(‘menu’);
  8.                 $menu = $this->menu->ListModules($dist_id, $arch_id);
  9.  
  10.                 $data = array (
  11.                         “title” => “Distribution’s modules list”,
  12.                         “menu_prefix” => “/dunno/yet/”,
  13.                         array( // will be processed with MergeBlock()
  14.                                 “name” => “modules”,
  15.                                 “data” => $menu
  16.                 ));
  17.  
  18.                 $view = $this->load->view(’sidebar/menu.html’, $data);
  19.                 $view->render(TRUE);
  20.         }
  21. }

views/sidebar/menu.html:

PLAIN TEXT
HTML:
  1. <ol><li><a href=“[menu_prefix]/show/[modules.key;block=li]“>[modules.val]</a></li></ol>



Happy MVC-ing :-)
