Kohana Markdown

Last edited: Wed, 07 July 2010 (stroppytux)

A text-to-HTML conversion tool for web writers for Kohana 3.

Based off the php created by Michel Fortin under the gpl lisense. For more information, please refer to: http://michelf.com/projects/php-markdown/

Original Markdown concept by John Gruber. Please refer to: http://daringfireball.net/projects/markdown/

Markdown is a text-to-HTML filter; it translates an easy-to-read / easy-to-write structured text format into HTML. Markdown's text format is most similar to that of plain text email, and supports features such as headers, emphasis, code blocks, blockquotes, and links.

Markdown's syntax is designed not as a generic markup language, but specifically to serve as a front-end to (X)HTML. You can use span-level HTML tags anywhere in a Markdown document, and you can use block level HTML tags (like

and as well).

For more information about Markdown's syntax, see: http://daringfireball.net/projects/markdown/

Installation

1. Check out the main source

   Checkout the main repository from github. In order to do this, you will need a github key configured. Please check the github documentation for more details.

    git clone git@github.com:stroppytux/kohana-markdown.git markdown
   

   This should give you the following (in the markdown directory):

    README.md  classes  config
   

2. Configure Markdown

   Copy the configuration file located in markdown/config to your application configuration directory.

    cp modules/markdown/config/markdown.php application/config/
   

3. Enable Markdown

   In order to enable the markdown module, edit the application/bootstrap.php file and add and enable the markdown module.

    'markdown'		=> MODPATH.'markdown',		// Markdown module
   

4. Process strings

   Now add the markdown transformer in between the value received from the user, and the storage. eg.

    <?php defined('SYSPATH') or die('No direct script access.');
   
    class Model_Description extends Model {
   
    	public function add($data)
    	{
    		$query = DB::query(Database::INSERT, '
    		INSERT INTO `Descriptions`
    			(`d_title`, `d_description`)
    		VALUES
    			(:title, :description)');
   
    		/* Sort out the description */
    		$description = Markdown::instance()->transform($data['description']);
   
    		/* Add the paramaters to the query */
    		$query->param(':title', $data['title']);
    		$query->param(':description', $description);
    		return $query->execute();
    	}
    }
