Enabling Compression on a Magento Site on OpenSuse 0

January 26th, 2010

If you’re running Magento on OpenSuse (or any platform for that matter), you can really benefit from turning on http compression, especially to remote areas or from hosts that have limited bandwidth.

There are a lot of references out there on this, but you have to sort of pull it all together on your own for this particular combination.

Verify that mod_deflate has been installed in Apache:

1. Open /etc/sysconfig/apache2.

2. Find the line that starts:

APACHE_MODULES=…

3. Verify that “deflate” is one of the modules listed (may not be in alphabetical order).

Now, enable compression in the virtual host file for your site:

1. Open /etc/apache2/vhosts.d/.conf.

2. Add the following lines inside the tag:


    <IfModule mod_deflate.c>
	DeflateBufferSize 32768
	DeflateCompressionLevel 5

	<Location />
		SetOutputFilter DEFLATE
		BrowserMatch ^Mozilla/4 gzip-only-text/html
		BrowserMatch ^Mozilla/4\.0[678] no-gzip
		BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
		SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|tiff)$ no-gzip dont-vary
		# Header append Vary User-Agent env=!dont-vary
	</Location>
    </IfModule>

Now restart Apache using:

sudo /etc/init.d/apache2 restart

and you should be in business!

Validate that compression is working

A great, handy online site that you can use to validate that compression is working is http://www.gidnetwork.com/tools/gzip-test.php.

Clearing Test Data From Magento 0

November 2nd, 2009

On many occasions we’ve needed to clear out the test data from a Magento site in preparation for going live.  It’s not as trivial as you’d think, but I found a nice sql script thanks to Elias Interactive that was just what I needed.  I’ve removed a bit as I didn’t need to reset all the order numbers, etc.

-- Reset Magento TEST Data

SET FOREIGN_KEY_CHECKS=0;

-- reset dashboard search queries
TRUNCATE `catalogsearch_query`;
ALTER TABLE `catalogsearch_query` AUTO_INCREMENT=1;

-- reset sales order info
TRUNCATE `sales_order`;
TRUNCATE `sales_order_datetime`;
TRUNCATE `sales_order_decimal`;
TRUNCATE `sales_order_entity`;
TRUNCATE `sales_order_entity_datetime`;
TRUNCATE `sales_order_entity_decimal`;
TRUNCATE `sales_order_entity_int`;
TRUNCATE `sales_order_entity_text`;
TRUNCATE `sales_order_entity_varchar`;
TRUNCATE `sales_order_int`;
TRUNCATE `sales_order_text`;
TRUNCATE `sales_order_varchar`;
TRUNCATE `sales_flat_quote`;
TRUNCATE `sales_flat_quote_address`;
TRUNCATE `sales_flat_quote_address_item`;
TRUNCATE `sales_flat_quote_item`;
TRUNCATE `sales_flat_quote_item_option`;
TRUNCATE `sales_flat_order_item`;
TRUNCATE `sendfriend_log`;
TRUNCATE `tag`;
TRUNCATE `tag_relation`;
TRUNCATE `tag_summary`;
TRUNCATE `wishlist`;
TRUNCATE `log_quote`;
TRUNCATE `report_event`;

ALTER TABLE `sales_order` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_datetime` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_decimal` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity_datetime` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity_decimal` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity_int` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity_text` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_entity_varchar` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_int` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_text` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_varchar` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_quote` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_quote_address` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_quote_address_item` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_quote_item` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_quote_item_option` AUTO_INCREMENT=1;
ALTER TABLE `sales_flat_order_item` AUTO_INCREMENT=1;
ALTER TABLE `sendfriend_log` AUTO_INCREMENT=1;
ALTER TABLE `tag` AUTO_INCREMENT=1;
ALTER TABLE `tag_relation` AUTO_INCREMENT=1;
ALTER TABLE `tag_summary` AUTO_INCREMENT=1;
ALTER TABLE `wishlist` AUTO_INCREMENT=1;
ALTER TABLE `log_quote` AUTO_INCREMENT=1;
ALTER TABLE `report_event` AUTO_INCREMENT=1;

Just run this script against the Magento database (make a backup first!).

Logging all SQL in Magento 2

October 18th, 2009

I’ve been looking for a way to log all the sql that Magento is running for debugging purposes. There are a number of logging mechanisms built in to Magento, but none that would allow you to log all the sql that’s being run. Finally, I’ve found a simple change that can be made to a core file (I know, not ideal because it will get overwritten when you upgrade Magento – but it’s only a few lines in one file).

The Change

1. Open the file <magentoroot>/lib/Varien/Db/Adapter/Pdo/Mysql.php.

2. Add the following lines:

$code = 'SQL: ' . $sql . "\r\n";
if ($bind) {
     $code .= 'BIND: ' . print_r($bind, true) . "\r\n";
}
$this->_debugWriteToFile("[".date('Y-m-d H:i:s')."] ".$code);

Add it to the “query” function as shown below:

public function query($sql, $bind = array())
{
     $this->_debugTimer();

     try {
          $sql = (string)$sql;
          if (strpos($sql, ':') !== false || strpos($sql, '?') !== false) {
               $this->_bindParams = $bind;
               $sql = preg_replace_callback('#(([\'"])((\\2)|((.*?[^\\\\])\\2)))#', array($this, 'proccessBindCallback'), $sql);
               $bind = $this->_bindParams;
          }

          $code = 'SQL: ' . $sql . "\r\n";
          if ($bind) {
               $code .= 'BIND: ' . print_r($bind, true) . "\r\n";
          }
          $this->_debugWriteToFile("[".date('Y-m-d H:i:s')."] ".$code);

          $result = parent::query($sql, $bind);
     }
     catch (Exception $e) {
          $this->_debugStat(self::DEBUG_QUERY, $sql, $bind);
          $this->_debugException($e);
     }
     $this->_debugStat(self::DEBUG_QUERY, $sql, $bind, $result);
     return $result;
 }

jQuery, Magento and Ajax Add to Cart Redux 9

October 15th, 2009

My previous post on adding to the cart with ajax in Magento has generated enough interest – and pointed out enough flaws in my overly complex code – that I’ve decided to put together a simplified version, so here goes:

ajaxAddToCart.zip

Step 1: Create the server side script.
My sample script is called “addToCartTest.php” and I put it in a /scripts folder in the root of my Magento installation.


< ?php
include_once '../app/Mage.php';
Mage::app();

try{
     // usage /scripts/addToCartTest.php?product_id=838&amp;amp;amp;qty=1
     $product_id = '';

     // get query string
     if (!isset($_GET['product_id'])) { $product_id = ''; } else { $product_id = $_GET['product_id']; }
     if (!isset($_GET['qty'])) { $qty = '1'; } else { $qty = $_GET['qty']; }

     $product = Mage::getModel('catalog/product')->load($product_id);

     $session = Mage::getSingleton('core/session', array('name'=>'frontend'));
     $cart = Mage::helper('checkout/cart')->getCart();

     $cart->addProduct($product, $qty);

     $session->setLastAddedProductId($product->getId());
     $session->setCartWasUpdated(true);

     $cart->save();

     $result = "{'result':'success'}";
     echo $result;

} catch (Exception $e) {
     $result = "{'result':'error'";
     $result .= ", 'message': '".$e->getMessage()."'}";
     echo $result;
}

Creating a new Product Attribute and then using it on a page in Magento 0

September 29th, 2009

Creating a new product attribute and using it when you’re displaying a product turns out to be fairly simple – but I know for us at iFuel – and I think for lots of others based on the posts you see around the net, it ends up not being as simple as it seems.

For this example, we’ll create a new attribute called “ingredients”.  We need this to be a text field (text area to be exact) that Magento admins can enter the product ingredients.  Then we’ll need to be able to access this text when we display the product.

Attributes

Attributes are single pieces of information that can be assigned to any of the entities (models) in the Magento system.  There is an extensive user interface for creating and maintaining attributes and attribute sets for products.  But you can actually create attributes for other entity types, like categories, too.  (Creating an attribute for a category has to be done right in the database – I’ll try to cover that in a future post).

To create an attribute:

iFuel Standardizes on Magento Commerce 0

September 10th, 2009

After using many many commerce packages – and WRITING many many commerce packages from scratch, we’ve standardized on Magento Commerce for all new e-commerce sites.  It’s an awesome platform, with huge potential for customization and extension.  The list of existing modules (plug-ins basically) is very large and growing all the time.  This is the way to put up new e-commerce sites, no question about it!

We’ll be posting lots and lots of Magento information in the weeks and months to come as we continue on our journey with this great tool!

Adding to the Cart with a jQuery Ajax Call in Magento 8

September 10th, 2009

So, Ajax being the thing and all, I was hunting for a way to add an item to the cart using an Ajax call in Magento.  Recently, I noticed there was a module that apparently does this, but either I hadn’t seen that or it didn’t exist yet when I wrote this, so I hacked my way through it.

PHP isn’t my primary language – I come from the ASP, ASP.Net, C# world, but Magento was compelling enough that I’ve taken the leap.  I’m sure there are lots of things I could be doing better/differently here so if you’ve got some suggestions, I’m all ears!

Add to Cart Page

So first I needed an “Add to Cart” page (called – addToCart.php) that could be called from the client.  This page returns a result in JSON format.  The actual page also returns related items so we can try to cross sell the user, but I’ve removed that in this sample to make it simpler.
