Magento Product Attribute Search and Filter

Magento Product Attribute Advanced Search and FilterThe Magento product database is pretty flexible when it comes to extracting product information. Sometimes however, extracting all the information you want for a product is not so easy.

For example you want to extract the main product info, price, title, SKU etc and all the product attributes names and the product category. This might require multiple product / collection calls and when you multiply this by a search across 1000′s of products can become slow.

Magento Product Attribute Search and Filter

I wanted to provide a quick and easy way to search and filter magento products by attributes, in this case by colour, so customers could quickly narrow product selection down by selecting a colour and a filtering by category.

To extract the data I developed my Magento Product Data and Attribute exporter. This let me initially see how many attributes I had to work with, in this case how many different product colours were already configured.

To make colour selection simpler I created a new Magento attribute product_primary_colour and added a primary colour to each product so that I ended up with about 16 main colours that would provide a match to all the existing product attribute colours.

Once I had all my exported product data in a tab delimited text file I quickly realised that it would be relatively simple to search and filter this data via ajax requests.

I had initially thought it would be more effective to do the search within Magento using product collections but the speed of the search against the delimited txt data file made me think again. When I then added cached search results using Memcache I was happy that this solution would work.

The benefits of using the flat txt file are that it is quick and can run completely external from Magento in another webapp or in WordPress or Facebook.

The Magento attribute search and filter is easily customiseable and can search the data created by the export script filtering results from any of the product data columns in the export file. This could be colour, size, type etc, there are no limits.

If your product data is changing regularly simply export the data regularly via a cron job to keep it up to date.

if you need to filter your data by a completely new attribute simply pull the export data into Excel, create your new attribute data and corresponding Magento attribute and import the data back into Magento. Now you can export this data and easily search and filter it.

Here is an example of the attribute search running in an iframe using the Magento test product data. Here I have exported the color attribute, and am filtering against existing product categories like Womens, Mens and Shirts (note Mens matches Womens, some refinement needed there!). This will also easily run in Magento when setup in a static block containing the iframe data.

You can see how quickly the data is filtered and returned, try a search for Red to see some data. Click around the categories and check the debug footer which shows if the results were cached or not and how long the ajax query took to run.

Magento Product Data and Attribute Exporter

Export Magento Product and Attribute DataOver the last few years I have developed a few different PHP scripts to export Magento product data in order to manipulate product pricing, generate Magento  EAN barcodes or create product import data.

Recently I had to export Magento product data to be used as import data for Amazon product listings. Specifically the products had a lot of different attributes associated with them and I wanted to export each product with all of its associated attribute data to map to the relevant Amazon product data.

To accomplish this I returned to my previous code and enhanced it to be able to export user defined Magento product and attribute data to a delimited text file (as well as creating product EAN barcodes which was a function of the original script.)

The script can extract the usual global product data e.g. price, description etc. as well as any custom product attributes.

The export data is configured in an array;

$_getProductData=array(
‘name’ => true,
‘description’ => false,
‘imageurl’ => true,
‘producturl’ => true,
‘type’ => false,
‘ean’ => false,
‘category’ => true
);

We set the array key value to true or false for the product data we want to export. The same applies to attribute data:

$_getProductAttributes=array(
‘colour1′ => ‘color’,
‘custom’ => ‘my_custom_attribute’
);

So here we are exporting the color product attribute as well as a custom attribute.

The tab delimited data is easily imported into Excel for manipulation and further import/export, for example adaption to an Excel format compatible with Amazon product imports.

This data can also become really useful if you want to provide fast external access to your product info for example, in an external app, on Facebook or even within Magento. See my product attribute search app for more information.

You can download the source code for this export script from my Github.

To run the script copy the files to your server and edit the configuration php file config/applicationConfig.php. Configure the paths to your Magento installation and the folder to export to.

Configure the product arrays by editing php/Application.php, edit $_getProductData and $_getProductAttributes.

To run the script execute it with php export.php debug from the command line. To run silently from a cron job leave the debug switch out.

You can also run the script from your web browser if you install it in a web accessible folder.

Here is an example of the output from my Magento dev store ::

Upgrade Magento 1.8 to 1.9

Magento Upgrade

Magento CE 1.9 has been released. It appears to be a relatively small update introducing a new responsive GUI. See the release notes here.

Here are my notes after upgrading my dev store from 1.8.x to 1.9 using the command line.

Backup existing install folder and database

1. Magento source
tar -cvvf /home/backup/magento.tar /home/www/magentoinstallfolder/

2. Magento DB
/usr/bin/mysqldump -h localhost -u USER -pPASS magento | gzip > ~/backup/folder/db-magento.sql.gz

1. Remove cached files and temp files

rm -rf downloader/pearlib/cache/*
rm -rf downloader/pearlib/download/*
rm -rf downloader/var/cache/*
rm -rf downloader/var/report/*
rm -rf downloader/var/tmp/*
rm -rf media/catalog/product/cache/*
rm -rf media/tmp/*
rm -rf var/cache/*
rm -rf var/session/*

2. Restart memcached (if being used)

3. Sync mage

./mage mage-setup

./mage sync

4, Run upgrade

./mage upgrade-all

5. Reset ownership and permissions on all files and folders.

Check Magento is operational, login and refresh caches.

If all is well take a well deserved break and maybe eat a cream cake. If all is not well restore from backup…

 

 

Google Universal Analytics Update for Magento Version v.1.3.X Old Versions

gua

Google Universal Analytics went out of BETA recently (May 2014) and is now available for all users. Universal Analytics has “more features, better insights”.

All versions of Magento include the client side analytics code which can be enabled in Magento Admin. When enabled Magento creates the client side html and javascript and appends it to the footer section of each page.

On the checkout completion page additional code is created to track sales.

Google Univeral Analytics Magento

Google Universal Analytics uses new client side javascript code, this means Magento does not yet support Google Universal Analytics by default, however it is relatively easy (if you are using new versions of Magento) to override the base/default Magento code that creates the client side analytics html and javascript.

If you simply turn off the built in Magento analytics feature and add the new Google Universal Analytics code to your page templates (as Google suggests you do) then you will lose all eCommerce tracking.

You can update your Magento core code to support Google Universal Analytics using the information below.

New Versions > 1.4.x

If you are using a newer version of Magento i.e. > 1.4.1.x you can update the core analytics functionality following the guidelines here.

Old Versions < 1.4.x

if you are using an older version of Magento (before 1.4.1) i.e. Magento 1.3.x, I have adapted the Magento v1.3.x google analytics core module code to support Google Universal Analytics. The code can be installed as a local module and will override the core module.

Download the code from my GitHub

To install the module copy the files to your Magento app folder, refresh your Magento configuration and configure the settings under Configuration -> Google API -> Google Analytics.

To view the analytics code look at the source code of any page, scroll to the bottom and look for the code between the Google Universal Analytics Code comment tags. For order tracking information, check the code on the Checkout/Success page.

Magento SEPA Migration Check List

The Single Euro Payments Area (SEPA) is a payment-integration initiative of the European Union for simplification of bank transfers denominated in euro.

If you make or accept payments via direct bank transfers then you will know all about SEPA. As a customer online payment method direct bank transfers are popular in some countries (i.e. Germany) and not so popular in others (i.e the UK).

The deadline for SEPA payments was 1st February 2014 but (as of the time of writing) has been extended 6 months to 1st August 2014.

SEPA standardises bank transfers in Europe, replacing bank specific account and sort code numbers with an IBAN (International Bank Account Number) and BIC (Business Identifier Code).

For most businesses the migration to SEPA involves communicating the new changes to customers and migrating bank account numbers and sort codes to IBAN and BIC.

For Magento stores if you have a payment method that allows customers to pay via a direct bank transfer then you need to ensure that you can capture IBAN and BIC numbers at checkout. Until 1st August 2014 you can decide to give the customer the option of entering either bank account number and sort code or IBAN and BIC. From August 1st you *should* only be accepting IBAN and BIC.

Here is what you need to do to get your Magento Store ready for SEPA payments

  • Make sure you are capturing bank account information in the SEPA format – IBAN and BIC at checkout.
  • Check that your validation rules work for the IBAN and BIC formats.
  • Make a note to remove input fields and validation rules for old account formats, bank account number and sort code.
  • Upgrade your existing debit payment methods to make sure they support SEPA.
  • Implement a validation system for IBAN and BIC

This debit module is perfect for German Magento shops implengint Direc Debit (Lastschrift) payment methods and supports SEPA : https://github.com/therouv/Magento-DebitPayment

To validate IBAN account numbers with PHP take a look at https://code.google.com/p/php-iban/

 

 

Javascript only EU Law Cookie Notification Message for WordPress and Magento

You know sometimes you just want a quick solution to a problem and wherever you look there are just complex, overpriced scripts that make your simple problem sound like something that needs a lot of code and money to get to work.

I needed to display a cookie notification message on a wordpress and magento site, to avoid compatibility problems I wanted to avoid using jQuery and just do it as simply as possible in javascript.

After looking around at a lot of $10 jQuery solutions I found a free javascript only solution, modified it for Magento and WordPress and implemented it.

Download the code from Github here

Whatever your opinion of the EU Cookie Law which came into effect in 2012, sooner or later if you are in Europe you may need to show that you are doing something about it. Err actually it’s 2014, so I guess we are already a teeny weeny bit late.

From what I understand the law may differ in various countries (certainly outside Europe), so depending on where your website is, and who visits your site the law may or may not apply to you.

This script will let  you quickly implement a cookie notification banner with a link to your privacy policy. The notification itself uses cookies and will not be show again when closed.

You can implement this solution on any website by copying the install files to your web server and adding the following code to the footer of your site.

<script type=”text/javascript”>

var cookieNotificationURL='/cookies/';
var cookieNotificationLifetime=180;
var cookieNotificationMessage='This website uses cookies. For more information please ';
var cookieNotificationClickMessage='click here';
var cookieNotificationMessageFade=true;
var cookieNotificationPath='/path-to-install-folder/
</script>

<script type="text/javascript" src="/js/cookienotification/cookie.notification.min.js"></script>

This sets up some variables used by the script, the URL of the privacy info page, the lifetime of the cookie used by the script in days, messages displayed, the option to fade the message automatically and the path to the install folder – used to display the close image.

For wordpress simply paste this into the footer php file of your theme.

For Magento paste this into the footer.phtml template file of your Magento theme. You can translate the messages, and perhaps a good idea, choose to display the message only on non SSL pages – we don’t want this javascript to somehow screw up a sale!

<?php if (empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] = ‘off’): ?>

<!-- Cookie Notification -->
<script type="text/javascript">
var cookieNotificationURL='/datenschutzerklaerung/';
var cookieNotificationLifetime=180;

<?php if (Mage::app()->getStore()->getId()==2): ?>
var cookieNotificationMessage='This website uses cookies. For more information please ';
var cookieNotificationClickMessage='click here';
<?php else: ?>
var cookieNotificationMessage='Diese Website verwendet Cookies. ';
var cookieNotificationClickMessage='Klicken Sie hier für weitere Informationen.';
<?php endif ?>
</script>

<script type="text/javascript" src="/js/cookienotification/cookie.notification.js"></script>
<?php endif ?>

Here I am manually checking the store id and translating the text to German. Remember to refresh your Magento cache after editing and saving the footer template file.

You can see the code working on this WordPress blog below, and also with Magento on my Magento development site.

Tested with Magento 1.8.x, WordPress 3.blah, Chrome, Firefox, IE11. Detects mobile devices and modifies banner size accordingly.

Upgrading Magento 1.7 to 1.8.1.0

A few notes after upgrading to Magento 1.8.1.0 from 1.7.0.0.

Make sure you backup your Database and Magento source directory first! My first upgrade attempt using Magento connect (via SSH) failed, The following error appeared when trying to load the site

“Call to a member function rewrite() on a non-object”

After googling the error and trying a few suggestions the install was still broken so I restored from backup and tried again. This time I followed the following steps

1. Remove cached files from /var/cache and /var/session

2. Restart memcached (if being used)

3. Sync mage

./mage-setup

./mage sync

4, Run upgrade (with force switch)

./mage upgrade-all –force

5. Reset ownership and permissions on all files and folders.

Magento loaded without error.

There are no major database changes between 1.7.0.0 and 1.8.1.0 so you can restore your 1.7 installation and switch between the two versions quite easily if you need to do any debugging etc.

 

Magento HTML Invoices, Print, Save, PDF

A Magento invoice display and printing system using PHP that can run externally to Magento.

The application displays Magento orders based on a time range in days and lets you display or print them with one click.

You can select a range of orders and preview the invoices, or print them by clicking on each order to select it. and clicking the print button.

Acknowledged orders (printed orders) are recorded and shown with a print symbol next to the order. (requires a configured cache folder writeable by www user.)

Click the time range to change the order time range in days. Some customer data can be edited directly in the app and exported to a text file which can be useful for automatic imports to shipping software etc.

Invoices can be displayed in the language they were placed in – simply create a translation file for your language and configure the application store id’s and languages.

Tested with
Chrome and Firefox – IE9/10 has some issues with printing.
Magento 1.3x – 1.7x (Community Edition)

Source codehttps://github.com/gaiterjones/magento-invoices

Copy the source files to a web accessible folder and configure settings in the configuration files. Point your browser at the installation folder to view orders.

BETA Demo below NOTE - no application security has been included, you should secure the application folder with Apache or implement a PHP login system. Installing the app in a public folder will give public read/write access to your Magento data!

Enable Magento iPhone Theme for Mobile Browsers

Magento Default IPhone theme

Do you know how many of your customers are visiting your site using a mobile device? If you don’t, take a quick look at your Google analytics and check the figures under Audience -> Mobile -> Overview and Devices. If the % of visits from mobile devices is more than 10% of your total site visits then you might want to think about providing specific content for mobile visitors to your Shop otherwise you maybe losing out on sales.

Mobile Device Visitor stats from Google Analytics

Since Magento v1.4.x a built in mobile theme called iPhone is included with the source code.but it is not enabled by default. Here is a quick fix to enable the built in Magento iPhone theme for your Magento store to provide a better browsing experience for visitors using mobile devices.

Login to admin and goto System -> Configuration. Click on General in the left hand menu and then DesignExpand the theme section and then configure the following exceptions under Templates, Skin and Layout.

Matched Expression - iPhone|iPad|iPod|Android|IEMobile

Value – iphone

Configure Exceptions for iPhone Theme

Configure Exceptions for iPhone Theme

 

Click Save to save your settings.

Notice the user agents in the matched expressions, these define which mobile browsers identified by User Agent should use the mobile theme. The iPad has a fairly large screen so you might decide to exclude that for example.

If you visit your store now with a mobile device you will see the default iphone theme in action.

Actually – its not very good is it, but it’s better than nothing and provides a good place to start building your own mobile theme. Alternatively (and I don’t say this very often) invest some $$ in the Aheadworks Mobile theme because it really is excellent.

Whichever mobile theme you decide to use make sure you test it thoroughly on your staging server, especially if you have a lot of extension modules installed. You may need to customise the mobile theme to achieve the same functionality as you have from your desktop version. Remember to include an option switch from desktop to mobile versions on both sites so that visitors can also decide which theme they want to use.

For testing (if you don’t have a mobile device) set the user agent in your browser to a mobile browser i.e. iPhone. This is possible in Safari by enabling Developer Mode and clicking Develop -> User Agent and selecting a mobile version of Safari from the drop down list. If you are a Mac user you can also use Xcode to run up an iPhone simulator as used for the screenshots above.

If your desktop site uses Flash, now is the time to start replacing it with HTML5 :)

 

Cannot log into Magento Admin? Magento Admin not loading? Magento Cache Refresh Script

It is possible to lock yourself out of the Magento back end admin interface simply by disabling a module which affects html rendering and stops you from logging back into the admin interface – which you need to do to re-enable the module – DOH! Its a real catch 22 situation.

If you are locked out of Magento admin, or your admin pages are not rendering correctly due to an admin change this post may just save your bacon.

If you have disabled an extension and need to re-enable it but the admin interface is not working, load up PHPMyAdmin and browse to your Magento database. Find the core_config_data table and then page through all the config options until you find the advanced/modules_disable_output rows. Find your disabled module – it will have a value of 1, and change the value back to 0 to enable it.

Paste the following code into a new .php file and save it to the root folder of your Magento store and run it in your browser. It will refresh the Magento cache, and re-enable the disabled module. Hopefully you should then be able to access admin again.

Depending on what has gone wrong with your configuration this may not always work, but if you have modified an admin config that for whatever reason has locked you out of admin then this method may work for you. It certainly is less painless than a full DB restore which is perhaps your other option.

Here is the cache refresh code.

<?php
require_once 'app/Mage.php';
umask( 0 );
Mage :: app( "default" );
$ver = Mage :: getVersion();
$userModel = Mage :: getModel( 'admin/user' );
$userModel -> setUserId( 0 );
Mage :: getSingleton( 'admin/session' ) -> setUser( $userModel );
echo "Refreshing cache...\n";
Mage :: app() -> cleanCache();
$enable = array();
foreach ( Mage :: helper( 'core' ) -> getCacheTypes() as $type => $label ) {
$enable[$type] = 1;
} 
Mage :: app() -> saveUseCache( $enable );
echo "Cache refreshed";
