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: addMarkup( 'foo', Zend_Markup_Renderer_RendererAbstract::TYPE_REPLACE, array( 'start' => '-bar-', 'end' => '-baz-', 'group' => 'inline' ) ); // now, this will output: 'my -bar-markup-baz-' 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. 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: Now you can add the 'upper' markup, with as callback, an instance of the My_Markup_Renderer_Html_Upper class. A simple example: addMarkup( 'upper', Zend_Markup_Renderer_RendererAbstract::TYPE_CALLBACK, array( 'callback' => new My_Markup_Renderer_Html_Upper(), 'group' => 'inline' ) ); // now, this will output: 'my !up!MARKUP!up!' echo $bbcode->render('my [upper]markup[/upper]'); ]]> List of markups List of markups Sample input (bbcode) Sample output [b]foo[/b] foo]]> [i]foo[/i] foo]]> [cite]foo[/cite] foo]]> [del]foo[/del] foo]]> [ins]foo[/ins] foo]]> [sup]foo[/sup] foo]]> [sub]foo[/sub] foo]]> [span]foo[/span] foo]]> [acronym title="PHP Hypertext Preprocessor]PHP[/acronym] PHP]]> [url=http://framework.zend.com/]Zend Framework[/url] Zend Framework]]> [h1]foobar[/h1] foobar]]> [img]http://framework.zend.com/images/logo.gif[/img] ]]>
