Installing Magento without Mcrypt

problem: 
Can't install magento as mcrypt is not enabled on php server, that happend on most of shared hosting

Solution:

Step One: edit /app/code/core/Mage/Install/Installer/Env.php, and find

                Mage::getSingleton('install/session')->addError(
                    Mage::helper('install')->__('PHP Extension "%s" must be loaded', $extension)
                );
just above it, add

                if ($extension == 'mcrypt') {
                    return true;   
                }
Step Two: create /lib/Varien/Crypt/Base64.php and throw this into it

<?php

class Varien_Crypt_Base64 extends Varien_Crypt_Abstract {
    public function __construct(array $data=array()) {
        parent::__construct($data);
    }

    public function init($key) {
         return $this;
    }

    public function encrypt($data) {
        if (!strlen($data)) {
            return $data;
        }
        
        return base64_encode($data);
    }
    
    public function decrypt($data) {
        if (!strlen($data)) {
            return $data;
        } 

        return  base64_decode($data);
    }
}
Last Step: edit /lib/Varien/Crypt.php and change

    static public function factory($method='mcrypt')

with

    static public function factory($method='base64')

just done.

Update K2 to send mail notifications on new comments

Problem:

Really it's not a problem, is a new requirement to allow Joomla K2 component to send notifications when a new comment has been published on frontpage; i still don't understand how that functionality has not been implementd on standar release of K2.

Solution:

we need to edit the code that allow to save new comments, you can find that on components/com_k2/models/item.php once.

1.- edit item.php and search for function comment()

2.- search string "...K2_COMMENT_ADDED_AND_WAITING_FOR_APPROVAL..."

3.- before that line add the next code:

$mainframe = &JFactory::getApplication(); $mail = &JFactory::getMailer(); $senderEmail = $mainframe->getCfg('mailfrom'); $senderName = $mainframe->getCfg('fromname'); $mail->setSender(array($senderEmail, $senderName)); $mail->setSubject(JText::_('K2_COMMENT_REPORT')); $mail->IsHTML(true); $body = " <strong>".JText::_('K2_NAME')."</strong>: ".$name." <br/> <strong>".JText::_('K2_REPORT_REASON')."</strong>: ".$reportReason." <br/> <strong>".JText::_('K2_COMMENT')."</strong>: ".nl2br($row->commentText)." <br/> "; $mail->setBody($body); $mail->ClearAddresses(); $mail->AddAddress($params->get('commentsReportRecipient', $mainframe->getCfg('mailfrom'))); $mail->Send();
