New System Event for Mollom?

Jason, how would you load this as an extension in 0.9.6? The DocumentParser does have a loadExtension() method but it can only load DBAPI and managerAPI.

I can imagine using a plugin triggered by the onWebPageInit to load the mollum class (and provide a global instance if necessary), but beyond that I don’t see how to make it an extension of the modx object. Or am I misunderstanding?

I’m trying to get my head around this. You basically want to make a third party service add-on that is then easily made available to other add-ons am I correct? I don’t see what the difficulty is for developers of those other add-ons to simply check if the particular add-on exists, include it , create an instance of it and use it in the same way you would for instance use PHPmailer or any other third party product.

In the front end, though, there’s really no common event that occurs before saving or emailing user content, but it would be easy for developers to invoke one when processing user input if it existed.

Now you are getting me confused The front end does not save anything and does not email anything and when in the core does it process front-end user input? So where would you have that event triggered? Isn’t it the snippets or plugins that do most of the processing, saving and emailing?

(still wondering, though, why Captcha is a plugin rather than a service since all the same arguments apply there, no?-- I’m sure there’s a good reason, I just can’t see it).

How do I instantiate a new XML-RPC client?

<?php
require_once MODX_CORE_PATH . 'model/modx/xmlrpc/xmlrpc.inc';
require_once MODX_CORE_PATH . 'model/modx/xmlrpc/xmlrpc_wrappers.inc';

class SampleService {
    var $modx;
    var $options;
    var $client;
    
    function SampleService(& $modx, $options = array()) {
        $this->modx = & $modx;
        $this->options = $options;
    }
    
    function &getServiceClient($url = '') {
        if (empty($this->client)) {
            $url = empty($url)
                ? (!isset($options['url']) ? '' : $options['url'])
                : $url;
            if (empty($url)) {
                $this->client = null;
            } else {
                $modx->loadClass('xmlrpc');
                $this->client = new xmlrpc_client($url);
            }
        }
        return $this->client;
    }
    
    function _callServiceMethod($method, $params = array()) {
        $response = null;
        if ($this->getServiceClient()) {
            $msgParams = array();
            foreach ($params as $param) $msgParams[] = new xmlrpcval($param);
            $msg = new xmlrpcmsg($method, $msgParams);
            $response = $this->client->send($msg);
        }
        return $response;
    }
    
    /* Add specific service methods to format complex parameters and/or transform the responses 
       to make it easier for users to call specific business methods of the service */
}


/* Code to use it would be like...(though you would really want to call specific business methods) */
if ($modx->getService('sample', 'SampleService', '', array('url' => 'http://localhost/some/service/url/'))) {
    $response = $modx->sample->_callServiceMethod('methodname', array('foo', 'bar', true));
    if (!$response->faultCode()) {
        /* do something with the expected response */
    } else {
        /* report an error */
    }
}
?>

Is there an advantage to using the jsonrpc subclasses for it as we do with regard in the modTransportProvider class?

Are there guidelines somewhere for creating a MODx service?

Because I didn’t implement it?

Right, I should have said, "create a reusable class the handle the details of Captcha and use it in a plugin or snippet, or wherever you need it". Ah, love that hindsight.

require_once MODX_CORE_PATH/ 'components/captcha/classes/veriword.class.php';

if ($modx=>config['captcha_use_mathstring']) {
    $vword = new VeriWord($modx,$width,$height, "MathString");
} else {
    $vword = new VeriWord($modx,$width,$height);
}
$vword->output_image();
$vword->destroy_image();
