Good tutorial

If your on the checkout/cart page, you can get the shipping totals:
$shipping_total = $this->getQuote()->getShippingAddress()->getShippingAmount();

After you ssh into server:
$ vi /etc/passwd

You should see something similar to
bloom:x:502:503::/var/www/vhosts:/bin/bash
devuser:x:48:505::/home/devuser:/bin/bash
bloomcom:x:503:506::/var/www/vhosts:/bin/bash

Just change the part where is says: /var/www/vhosts
to whatever folder you want

$ df -h ( hit enter )

Will return something similar to:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5             128G   80G   47G  64% /
/dev/sda2             2.0G  264M  1.6G  15% /tmp
/dev/sda1              99M   23M   71M  25% /boot
tmpfs                  16G     0   16G   0% /dev/shm

After logging in to your server via ssh:
 $ find / -type f -printf "%s %h/%f\n" | sort -rn -k1 | head -n 50 | awk '{ print $1/1048576 "MB" " " $2}' ( hit enter )

Using terminal

$ ps ax | grep httpd | wc -l

Edit PHP config file: /etc/php.ini

$ sudo nano /etc/php.ini

Do a search for pdo_mysql_default

In nano, type <control button> and press W

type in pdo_mysql_default and hit enter

Change to

 pdo_mysql.default_socket=/tmp/mysql.sock

Restart apache:

$ sudo apachectl restart

Taken from http://craigwaterman.com/2011/07/21/adding-mcrypt-to-php-on-os-x-10-7-lion/ but cleaned up a few potential gotchas:

This is a guide for those who need to install (or re-install) mcrypt under PHP in OS X 10.7 (Lion).

You’ll need the following:

• PHP Source Code—Lion seems to ship with 5.3.6, you can get that here. You should double-check your version with phpinfo() just in case.
• libmcrypt 2.5.8 (yes, it really is from 2007). that’s here. I grabbed the bz2 version.
• Xcode 4.1 – supported on Lion; it’s available on the Mac App Store. You’ll still need an Apple Developer account to download the post-install updates.
• A place to uncompress and compile everything, move your php and libmcrypt downloads here.
• I usually use a directory in under my home named Source. In this case, I’m putting everything in a Lion specific folder: /Users/sushi/Source/lion/

$ cd ~/Source/lion ( hit enter )
$ tar xvfj libmcrypt-2.5.8.tar.bz2 ( hit enter )
$ tar xvfz php-5.3.6.tar.gz ( hit enter )

Let’s configure libmcrypt for installation:

$ cd libmcrypt-2.5.8 ( hit enter )
$ MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS='-O2 -fno-common -arch i386 -arch x86_64' \
LDFLAGS='-O2 -arch i386 -arch x86_64' \
CXXFLAGS='-O2 -fno-common -arch i386 -arch x86_64' \
./configure --disable-dependency-tracking ( hit enter )

If you get some errors, try removing a few items:

$ MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS='-O2 -fno-common' \
LDFLAGS='-O2' \
CXXFLAGS='-O2 -fno-common' \
./configure --disable-dependency-tracking ( hit enter )

Now let’s build and install libmcrypt itself.

$ make ( hit enter )
$ sudo make install ( hit enter )

You can run make -j8 if you’re on a Quad-Core i7 and are curious how much it speeds up compilation, it makes no difference for installing mcrypt.

With libmcrypt ready to use, we need to compile the php extension for it.

$ cd ~/Source/lion/php-5.3.6/ext/mcrypt ( hit enter )
$ /usr/bin/phpize ( hit enter )
MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS='-O2 -fno-common -arch i386 -arch x86_64' \
LDFLAGS='-O2 -arch i386 -arch x86_64' \
CXXFLAGS='-O2 -fno-common -arch i386 -arch x86_64' \
./configure --with-php-config=/Developer/SDKs/MacOSX10.7.sdk/usr/bin/php-config ( hit enter )

( You might have to hit enter again to make it execute )

If you get some errors try removing a few things like we did above:

MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS='-O2 -fno-common' \
LDFLAGS='-O2' \
CXXFLAGS='-O2 -fno-common' \
./configure --with-php-config=/Developer/SDKs/MacOSX10.7.sdk/usr/bin/php-config ( hit enter )

$ make ( hit enter ) $ sudo make install ( hit enter )

Everything should be ready to hook up at this point, we’ll need to update /etc/php.ini to tell php to load the extension.

Verify that /etc/php.ini exists. If you’ve never worked with it before, or have just upgraded to Lion, you’ll need to copy php.ini.default to php.ini with:

# skip this step if /etc/php.ini already exists.
$ sudo cp /etc/php.ini.default /etc/php.ini ( hit enter )

Update php.ini and tell php to load our newly compiled mcrypt.so

$ sudo nano /etc/php.ini ( hit enter )

Add the following to the end of the file, then save and exit:

extension=mcrypt.so

Now restart Apache:

$ sudo apachectl graceful ( hit enter )

OR

$ sudo apachectl stop ( hit enter )

THEN

$ sudo apachectl start ( hit enter )

OR using Macs typical user interface:

• Open System Preferences
• Select Sharing
• Uncheck and re-check “Web Sharing”—this restarts the web server.
• For some reason my Web Sharing was unchecked even though Apache was already running, if this happens to you, just “check/uncheck/check” to make sure it’s actually restarted.

Verify in your phpinfo() that mcrypt is really there, it should look like this:

And that should be it

• Using Collections in Magento

Mage/Eav/Model/Entity/Collection/Abstract.php

Inherits above methods for Varien_Data_Collection_Db, and in addition (re)defines the following:

We needed to send a friendly reminder to some guests who have been invited to our Magento Enterprise store but never accepted.   We have a plugin that creates coupon codes and had it dump to a CSV and gave them some free reward points to spend if they came to our site and joined.

1. create the xml for our new Module in our package Bloom:

In app/etc/modules/ create a file called Bloom_SecondChanceEmail.xml

<?xml version="1.0"?>
<config>
<modules>
   <Bloom_SecondChanceEmail>
      <active>true</active>
      <codePool>local</codePool>
      <version>0.0.1</version>
   </Bloom_SecondChanceEmail>
</modules>
</config>

2. Create a folder and sub folders in /app/code/local/Bloom/

New folder SecondChanceEmail

New sub folders: etc, Model and sql

Inside etc create a file called config.xml

<?xml version="1.0"?>
<config>
	<modules>
		<Bloom_SecondChanceEmail>
			<version>0.0.1</version>
		</Bloom_SecondChanceEmail>
	</modules>
	<global>
        <models>
            <bloom_secondchanceemail>
                <class>Bloom_SecondChanceEmail_Model</class>
           	</bloom_secondchanceemail>
        </models>
		<resources>
            <secondchanceemail_setup>
                <setup>
                    <module>Bloom_SecondChanceEmail</module>
                </setup>
            </secondchanceemail_setup>
        </resources>
    	<template>
	      <email>
	        <secondchance_email_template translate="label" module="secondchanceemail">
	          <label>Second Chance Email</label>
	          <file>secondchance.html</file>
	          <type>html</type>
	          </secondchance_email_template>
	        </email>
	      </template>
	</global>
</config>

Inside Model create a file called Observer.php

<?php

class Bloom_SecondChanceEmail_Model_Observer {

    public function sendSecondChanceEmails() {

            $baseUrl    = Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_WEB);

            // get the template for sending the reminder email
            $templateId = Mage::getStoreConfig('secondchance_email/template');

            // subject
            $mailSubject = 'Your friend has sent you a gift from Bloom.com';

            // Sender email
            $sender = array(
                'name' => Mage::getStoreConfig('trans_email/ident_support/name'),
                'email' => Mage::getStoreConfig('trans_email/ident_custom1/email')
            );

            $supportEmail = Mage::getStoreConfig('trans_email/ident_support/email');

            $supportPhone = Mage::getStoreConfig('general/store_information/phone');

            $days_back = 45;

            $dateStart = date( "Y-m-d H:i:s", mktime( 0,0,0, date( "m" ), date( "d" ) - $days_back, date( "Y" ) ) );
            $dateEnd   = date( "Y-m-d H:i:s", mktime( 23,59,59, date( "m" ), date( "d" ), date( "Y" ) ) );

                //$pendingInvite = Mage::getModel('enterprise_invitation/invitation')->getCollection()->addFieldToFilter('status','sent');
            $pendingInvitations = Mage::getModel('enterprise_invitation/invitation')->getCollection()
             ->addFieldToFilter('date', array('from' => $dateStart, 'to' => $dateEnd))
             ->addFieldToFilter('status','sent')->getData();

        $row = 0;
        $file = $baseUrl . "secondchance.csv";
        $coupon_array = array();
        if (($handle = fopen($file, "r")) !== FALSE) {
            while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
                     $coupon_array[$row] = $data[0];
                $row++;
            }
            fclose($handle);
        }
            foreach( $pendingInvitations as $invite )
            {
                $storeId = $invite['store_id'];
                // Load the skin url based on the store ID
                Mage::app()->setCurrentStore($storeId);

                $customer_data = Mage::getModel('customer/customer')
                                    ->setWebsiteId(Mage::app()->getStore()->getWebsiteId())
                                    ->loadByEmail($invite['email'])->getData();

                if($customer_data)
                {
                    // Do nothing for now
                }
                else
                {
                    $couponCode = $coupon_array[$i];
                    // Set variables that can be used in email template
                    $vars = array(
                        'customerName' => $customerName,
                        'customerEmail' => $invite['email'],
                        'supportPhone' => $supportPhone,
                        'supportEmail' => $supportEmail,
                        'couponCode' => $couponCode
                    );

                        $translate = Mage::getSingleton('core/translate');

                        Mage::getModel('core/email_template')
                                ->setTemplateSubject($mailSubject)
                                ->sendTransactional($templateId, $sender, $invite['email'], $customerName, $vars, $storeId);
                        $translate->setTranslateInline(true);

                }
            }
    }
}

In sql create a folder called  secondchanceemail_setup

Inside the new folder secondchanceemail_setup create a file called mysql4-install-0.0.1.php

<?php

$installer = $this;
$installer->startSetup();

/* @var $installer Mage_Core_Model_Resource_Setup */

$configValuesMap = array(
  'secondchance_email/template' =>
  'secondchance_email_template',
);

foreach ($configValuesMap as $configPath=>$configValue) {
	$installer->setConfigData($configPath, $configValue);
}

$installer->endSetup();

In the main folder of your site create a csv file called secondchance.csv and put in some coupon codes but make sure you have either exactly how many you need to fulfill every invite or better yet a few more (we needed 4000! ). Here is a sample:

19VCH27
17LUG62
17FUE65
16UVL45
15PFC32
14ECJ28
13GJU35
14ENS67
15DHV65
15FUT82
14EAV75
13RAK87
14UNL82
13EUN73
15ETC64
11RWX25
12LPM45
12WVP73
13WCN32
12GNF86
12VUT98
13ARC82
13XNV78

Last step is to create a file in shell/ called secondChanceEmail.php

        $secondChance = new Bloom_SecondChanceEmail_Model_Observer();
        $secondChance->sendSecondChanceEmails();

    }

}

$shell = new Mage_Shell_secondAttemptSendInvite();
$shell->run();

Now to get this to run, you use ssh and log into your site, chance into the shell directory

$ cd shell/ ( hit enter )

then type this command

$ php secondChanceEmail.php ( hit enter )
