[ANN] CGMiner Wordpress Widget | Bitcointalksearch.org

Hi everybody, this is my small contribution to the community. Please be easy on me Wink

Since I've installed my RPi driving four USB Erupters, I thought I needed a web interface for it. Looking at available projects, I didn't found anything I liked. So I decided to configure my own portal with Wordpress. This is the only first step in integrating CGMiner stats with it but I think is already usable (even if it's really simple).

This is the result (look at the bottom left):

This is the configuration panel visible from Wordpress Dashboard where you can configure IP and Port of your miner:

And this is the widget source code:

Code:

function MinerWidget() {
$widget_ops = array( 'classname' => 'example', 'description' => __('A widget that displays statistics from CGMiner ', 'example') );

$this->WP_Widget( 'miner-widget', __('Miner Widget', 'example'), $widget_ops, $control_ops );
