Zend_Markup Renderers

Zend_Markup is currently shipped with one renderer, the HTML renderer.

Adding your own markups

By adding your own markups, you can add your own functionality to the Zend_Markup renderers. With the markup structure, you can add about any functionality you want. From simple markups, to complicated markup structures. A simple example for a 'foo' markup:

  1. // Creates instance of Zend_Markup_Renderer_Html,
  2. // with Zend_Markup_Parser_BbCode as its parser
  3. $bbcode = Zend_Markup::factory('Bbcode');
  4.  
  5. // this will create a simple 'foo' markup
  6. // The first parameter defines the markup's name.
  7. // The second parameter takes an integer that defines the markups type.
  8. // The third parameter is an array that defines other things about a
  9. // markup, like the markup's group, and (in this case) a start and end markup.
  10. $bbcode->addMarkup(
  11.     'foo',
  12.     Zend_Markup_Renderer_RendererAbstract::TYPE_REPLACE,
  13.     array(
  14.         'start' => '-bar-',
  15.         'end'   => '-baz-',
  16.         'group' => 'inline'
  17.     )
  18. );
  19.  
  20. // now, this will output: 'my -bar-markup-baz-'
  21. echo $bbcode->render('my [foo]markup[/foo]');

Please note that creating your own markups only makes sense when your parser also supports it with a markup structure. Currently, only BBCode supports this. Textile doesn't have support for custom markups.

Some renderers (like the HTML renderer) also have support for a 'markup' parameter. This replaces the 'start' and 'end' parameters, and it renders the markups including some default attributes and the closing markup.

Add a callback markup

By adding a callback markup, you can do a lot more then just a simple replace of the markups. For instance, you can change the contents, use the parameters to influence the output etc.

A callback is a class that implements the Zend_Markup_Renderer_TokenInterface interface. An example of a callback class:

  1. class My_Markup_Renderer_Html_Upper
  2.     implements Zend_Markup_Renderer_TokenConverterInterface
  3. {
  4.  
  5.     public function convert(Zend_Markup_Token $token, $text)
  6.     {
  7.         return '!up!' . strtoupper($text) . '!up!';
  8.     }
  9.  
  10. }

Now you can add the 'upper' markup, with as callback, an instance of the My_Markup_Renderer_Html_Upper class. A simple example:

  1. // Creates instance of Zend_Markup_Renderer_Html,
  2. // with Zend_Markup_Parser_BbCode as its parser
  3. $bbcode = Zend_Markup::factory('Bbcode');
  4.  
  5. // this will create a simple 'foo' markup
  6. // The first parameter defines the markup's name.
  7. // The second parameter takes an integer that defines the markups type.
  8. // The third parameter is an array that defines other things about a
  9. // markup, like the markup's group, and (in this case) a start and end markup.
  10. $bbcode->addMarkup(
  11.     'upper',
  12.     Zend_Markup_Renderer_RendererAbstract::TYPE_REPLACE,
  13.     array(
  14.         'callback' => new My_Markup_Renderer_Html_Upper(),
  15.         'group'    => 'inline'
  16.     )
  17. );
  18.  
  19. // now, this will output: 'my !up!MARKUP!up!'
  20. echo $bbcode->render('my [upper]markup[/upper]');

$bbcode->addMarkup(
'upper',
Zend_Markup_Renderer_RendererAbstract::TYPE_REPLACE,

in this case we must use a TYPE_CALLBACK
