Flattr Cakephp helper

EDIT: DerEuroMark wrote an excellent replacement for this helper.

After the Flattr MOD for phpBB3 release 2 days ago I wrote this simple flattr cakephp helper (basic cakephp helper knowledge is required) to aid cakephp developers integrate flattr quick and easy into their websites. The helper has only 1 function and is very simple in use.

Basic usage

echo $flattr->badge(array(
    'uid' => 4080,
    'tle' => 'test',
));

As you can see this is the bare minimum in options you need to use to get it to work.

  • uid The Flattr User ID as found on the Flattr dashboard (in the example I used mine).
  • tle The title for the link to be submitted.

Since the helper supports the full range of options below are the other options:

  • dsc A description for the link.
  • cat The category for the link. This can be any of the following: text, images, video, audio, software, rest. The default if this option isn't specified is text.
  • lng The language of the link. Any of the languages on this list and defaults to en_GB.
  • tags Any tags matching the link. This field must be an array!
  • url The URL of the link.
  • btn The badge to use. Currently the only option is compact but if not specified or set to something else it defaults to the standard larger badge

app/views/helpers/flattr.php

class FlattrHelper extends Helper {
    public $helpers = array('Javascript');
    function badge($options=array()) {
        App::import('Sanitize');
        $vars = '';
        $vars .= "var flattr_uid = '" . intval($options['uid']) . "';\r\n";
        $vars .= "var flattr_tle = '" . $options['tle'] . "';\r\n";
        if(!isset($options['dsc']))
        {
            $options['dsc'] = '';
        }
        $vars .= "var flattr_dsc = '" . $options['dsc'] . "';\r\n";
        if(!isset($options['cat']))
        {
            $options['cat'] = 'text';
        }
        $vars .= "var flattr_cat = '" . $options['cat'] . "';\r\n";
        if(!isset($options['lng']))
        {
            $options['lng'] = 'en_GB';
        }
        $vars .= "var flattr_lng = '" . $options['lng'] . "';\r\n";
        if(isset($options['tags']) && count($options['tags'])>0)
        {
            array_walk($options['tags'],'Sanitize::paranoid');
            $vars .= "var flattr_tag = '" . implode(', ',$options['tags']) . "';\r\n";
        }
        if(isset($options['url']) && ((version_compare(phpversion(), '5.2.0', '>=')  && function_exists('filter_var')) ? filter_var($options['url'], FILTER_VALIDATE_URL) : true))
        {
            $vars .= "var flattr_url = '" . $options['url'] . "';\r\n";
        }
        if(isset($options['btn']) && $options['btn']=='compact')
        {
            $vars .= "var flattr_btn = 'compact';\r\n";
        }
        $code = $this->Javascript->codeBlock($vars, array('inline' => true));
        $code .= $this->Javascript->link('http://api.flattr.com/button/load.js', array('inline' => true));
        return $code;
    }
}
