PHP-Decoda integration in Symfony2

A lightweight lexical string parser for BBCode styled markup.

Installation

To install this bundle, you'll need both the Decoda library and this bundle. Installation depends on how your project is setup:

Step 1: Installation

Using Composer, just add the following configuration to your composer.json:

Or you can use composer to install this bundle: Add FMBbcodeBundle in your composer.json:

{
    "require": {
        "helios-ag/fm-bbcode-bundle": "6.2"
    }
}

Now tell composer to download the bundle by running the command:

$ php composer.phar update helios-ag/fm-bbcode-bundle

Step 2: Enable the bundle

Finally, enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new FM\BbcodeBundle\FMBbcodeBundle(),
    );
}

Step 3: Dump emoticons (optional)

To enable emoticons via emoticon hook, use the following command to copy emoticons images to public folder (web/emoticons)

    ./app/console bbcode:dump

Basic configuration

Make the Twig extensions available by updating your configuration:

By default only "default" filter enabled, which provide support
for [b], [i], [u], [s], [sub], [sup], [abbr], [br], [hr], [time]
BBCodes

Examples to use the extension in your Twig template

Define BBCode filter in your config.yml:

    fm_bbcode:
      filter_sets:
        my_default_filter:
          strict: false # if you want to parse attr values without quotes
          locale: ru
          xhtml: true
          filters: [ default ]

And you can do the following:

     {{'[b]Bold text[/b]'|bbcode_filter('my_default_filter')}}
     {{'[u]Underlined text[/u]'|bbcode_filter('my_default_filter')}}
     {{'[i]Italic text[/i]'|bbcode_filter('my_default_filter')}}
    fm_bbcode:
      filter_sets:
        my_default_filter:
          locale: ru
          xhtml: true
          filters: [ default, quote ]
          whitelist: [ b, quote ]

After enabling "quote" filter, you can do such things:

      {{'[quote="helios"]My quote[/quote]'|bbcode_filter('my_default_filter')}}

Also you can define multiple filter sets under filter_sets parameter like this:

    fm_bbcode:
      filter_sets:
        my_forum_filter:
          locale: ru
          xhtml: true
          filters: [ default, quote ]
          whitelist: [ b, quote ]
        my_comment_filter:
          locale: ru
          xhtml: true
          filters: [ default, block, code, email, image, list, quote, text, url, video ]
      {{'[quote="helios"]My quote[/quote]'|bbcode_filter('my_forum_filter')}}
      {{'[code]My source code[/code]'|bbcode_filter('my_comment_filter')}}

Please keep in mind, that whitelist tags suppress tags, that applied by filters configuration.

Strip filter

To clear text from any bbcodes use bbcode_clean filter: example:

{{'[b]some text[/b]'|bbcode_clean}}

This filter will eliminate any known to decoda tags

Escaping and line breaks

Escaping and line breaks can be controlled via "escaping" and "line_breaks" parameters under filter configuration. Default configuration for them is 'true'. If you wish to pipeline filters, set escaping to false.

Advanced configuration

Overriding messages

Some templates and hooks, use text strings, that can be translated into different languages, the original file located under decoda/config directory, but content of this file can be overriden with messages option, under messages: node. File should be json formatted.

fm_bbcode:
    config:
      messages: @SomeBundle/Resources/config/messages.json

Adding own templates

Your own templates can be defined at templates node, the example below shows how:

    fm_bbcode:
        config:
          templates:
            - path: @SomeBundle/Resources/views/templates

Template examples can be found inside decoda library

Adding own filter

To enable a custom filter, add it as a regular service in one of your configuration, and tag it with fm_bbcode.decoda.filter:

services:
  acme_demo.decoda.filter.your_filter_name:
    class: Fully\Qualified\Filter\Class\Name
    tags:
      - { name: fm_bbcode.decoda.filter, id: your_filter_name }

Your service must implement the Decoda\Filter interface.

If your service is created by a factory, you MUST correctly set the class parameter for this tag to work correctly.

Adding own hook

To enable a custom hook, add it as a regular service in one of your configuration, and tag it with fm_bbcode.decoda.hook:

services:
  acme_demo.decoda.hook.your_hook_name:
    class: Fully\Qualified\Hook\Class\Name
    tags:
      - { name: fm_bbcode.decoda.hook, id: your_hook_name }

Your service must implement the Decoda\Hook interface.

If your service is created by a factory, you MUST correctly set the class parameter for this tag to work correctly.

Customize your own emoticons

Your own emoticons can be defined at emoticon node, the example below shows how:

fm_bbcode:
  emoticon:
    resource: path/to/emoticons.yml
# path/to/emoticons.yml
imports:
  - { resource: path/to/another/emoticons.yml }

emoticons:
  my_emoticon:
    url:   # Default: %fm_bbcode.emoticon.path%/my_emoticon.png
    html:  # Default: <img src="%fm_bbcode.emoticon.path%/my_emoticon.png" alt="" >
    xHtml: # Default: <img src="%fm_bbcode.emoticon.path%/my_emoticon.png" alt="" />
    smilies:
      - ":my_emoticon:"

How to automatically dump emoticons on each deploy

Add the following commands to you projects composer.json:

# composer.json
    "scripts": {
        "post-install-cmd": [
            "FM\\BbcodeBundle\\Composer\\ScriptHandler::installEmoticons"
        ],
        "post-update-cmd": [
            "FM\\BbcodeBundle\\Composer\\ScriptHandler::installEmoticons"
        ]
    }
