How to add billing address, shipping address, last 4 digits of CC to global search for Magento backend

Magento backend is having global search functionality,globalSearch
but we can not search few important fields or parameters using global search. 😦
Recently I came across a situation where I need to add many fields to the global search.
After few hours of research, I got the model classes from where it adds the fields to search.

There are three models for customer, product and order, one each.
Path of the files are: 


According to the requirement we can create our custom module in local and overwrite the file(model) over there. From the local we can modify the content of the file to add billing address, shipping address, last 4 digits of CC to global search.

The path of local file:


Note: “MyModule”  is my custom module name in local code pool.
Here I will explain how we can add different address parameters, order id , last 4 digit of CC, customers name etc. For this we will modify Order.php and Customer.php.


On this page : app/code/local/MyModule/Adminhtml/Model/Search/Order.php

 $query = $this->getQuery();
        //TODO: add full name logic
        $collection = Mage::getResourceModel('sales/order_collection')
                array('attribute' => 'increment_id',       'like'=>$query.'%'),
                array('attribute' => 'billing_firstname',  'like'=>$query.'%'),
                array('attribute' => 'billing_lastname',   'like'=>$query.'%'),
                array('attribute' => 'billing_telephone',  'like'=>$query.'%'),
                array('attribute' => 'billing_postcode',   'like'=>$query.'%'),

                array('attribute' => 'shipping_firstname', 'like'=>$query.'%'),
                array('attribute' => 'shipping_lastname',  'like'=>$query.'%'),
                array('attribute' => 'shipping_telephone', 'like'=>$query.'%'),
                array('attribute' => 'shipping_postcode',  'like'=>$query.'%'),

We need to change this snippet of code with following snippet to add order increment_id, billing details, shipping details and last 4 digits of CC.

$query = $this->getQuery();
$salesFlatQuotePayment = (string)Mage::getConfig()->getTablePrefix() . 'sales_flat_quote_payment';
            $collection = Mage::getResourceModel('sales/order_collection')->addAttributeToSelect('*');
                       ->joinLeft(array('sales_flat_quote_payment' => $salesFlatQuotePayment),
            ) ;
              $collection= $collection->addAttributeToSearchFilter(array(
                    array('attribute' => 'increment_id',                           'like'=>$query.'%'),
                    array('attribute' => 'entity_id',                              'like'=>$query.'%'),
                    array('attribute' => 'billing_firstname',                      'like'=>$query.'%'),
                    array('attribute' => 'billing_lastname',                       'like'=>$query.'%'),
                    array('attribute' => 'billing_telephone',                      'like'=>$query.'%'),
                    array('attribute' => 'billing_postcode',                       'like'=>$query.'%'),
                    array('attribute' => '',                       'like'=>$query.'%'),
                    array('attribute' => 'billing_o_a.region',                     'like'=>$query.'%'),
                    array('attribute' => 'billing_o_a.street',                     'like'=>$query.'%'),
                    array('attribute' => 'sales_flat_quote_payment.cc_last4',      'like'=>'%'.$query.'%'),

                    array('attribute' => 'shipping_firstname',                     'like'=>$query.'%'),
                    array('attribute' => 'shipping_lastname',                      'like'=>$query.'%'),
                    array('attribute' => 'shipping_telephone',                     'like'=>$query.'%'),
                    array('attribute' => 'shipping_postcode',                      'like'=>$query.'%'),
                    array('attribute' => '',                      'like'=>$query.'%'),
                    array('attribute' => 'shipping_o_a.region',                    'like'=>$query.'%'),
                    array('attribute' => 'shipping_o_a.street',                    'like'=>$query.'%'),

By adding this code we will be able to search by order increment_id, billing details, shipping details and last 4 digits of CC.


On this page : app/code/local/MyModule/Adminhtml/Model/Search/Customer.php

$collection = Mage::getResourceModel('customer/customer_collection')
            ->joinAttribute('company', 'customer_address/company', 'default_billing', null, 'left')
                array('attribute'=>'firstname', 'like' => $this->getQuery().'%'),
                array('attribute'=>'lastname', 'like'  => $this->getQuery().'%'),
                array('attribute'=>'company', 'like'   => $this->getQuery().'%'),
            ->setPage(1, 10)

We need to change this snippet of code with following snippet to add default billing address, customer’s  city, region and street.

$collection = Mage::getResourceModel('customer/customer_collection')
                ->joinAttribute('company', 'customer_address/company', 'default_billing', null, 'left')
                ->joinAttribute('city', 'customer_address/city', 'default_billing', null, 'left')
                ->joinAttribute('region', 'customer_address/region', 'default_billing', null, 'left')
                ->joinAttribute('street', 'customer_address/street', 'default_billing', null, 'left')

                    array('attribute'=>'firstname', 'like' => $query.'%'),
                    array('attribute'=>'lastname', 'like'  => $query.'%'),
                    array('attribute'=>'company', 'like'   => $query.'%'),
                    array('attribute'=>'city', 'like'      => $query.'%'),
                    array('attribute'=>'region', 'like'    => $query.'%'),
                    array('attribute'=>'street', 'like'    => $query.'%'),
                ->setPage(1, 10)

Now we can upload these two files and flush the cache. Then from backend search for any field from Global Search… 🙂



Use/Enable a payment method for back-end/admin-end orders only

In Magento, somtimes we need to enable the payment-method only for back-end orders.payment-methods
For this you can create new module in local and overwrite the payment method model in your local folder.
Following are the steps:
Note: You have enabled the method in the configuration for single/differnt store-views.
Create a new module and extend it from the class Mage_Payment_Model_Method_MethodName.
Change the variables:
protected $_canUseInternal = true;  // use in admin
protected $_canUseCheckout = false;  // use in frontend onepage checkout
protected $_canUseForMultishipping = false; // use in frontend multishippping checkout
$_canUseInternal  this variable responsible to show/hide payment method(s) for back-end orders.
$_canUseCheckout this varible is responsible to show/hide payment method(s) for frontend orders in case of onepage checkout.
$_canUseForMultishipping is responsible to show/hide payment method(s) for frontend orders in case of multishippping checkout.

Common Session Attacks (Session Fixation and Session Hijacking)

We developers use session protected functionality to restrict unwanted access, to provide security.  Do we know there are 2 very popular session attacks?

In the first type of attack, attacker can hijack any user’s session and use that same session to grab illegal privilege. This is called “session hijacking”.

In the second type of attack, attacker tricks to use her own specified session to victim which in turn disclose victims valuable details. In this way attacker fixes victim’s session, hence called “session fixation”.

In the both ways the main target is to use the same session which victim is using.

Procedure of Attack:

Except the initial step both type are same.

Session Fixation: This process starts before victim logs in. First atacker logs into the system and receive a valid session identifier (say sessionid = abcd). now attacker sets the victim’s session even bofore victim logs in.


Following are 2 basic way to trick user-<script>document.cookie=”sessionid=abcd”;</script><meta http-equiv=Set-Cookie content=”sessionid=abcd”>

Now if victim clicks on this type of link their session set to “abcd”. Now when victim logs in, same session id gets associated to his session.

Session Hijacking: In this process attacker try to grab a session which victim is using.

Following are few basic way to attack-

using cross site scripting –


Man-in-the-middle attack
Man-in-the-browser attack

Now the attacker impersonate as victim as she is using same session as victims session, and do whatever she wants.


Session Fixation:

-> Since Session Fixation starts before login, we can create a new session whenever an user logs in, hence preventing using of an existing session.
-> Use session_regenerate_id();

Session Hijacking:

Session hijacking cannot be directly prevented, however we can put steps in to make it very difficult and harder to use. Remember how difficult we can make it, attacker will leave and look for a softer target

-> Use a strong session hash identifier: session.hash_function in php.ini. If PHP < 5.3, set it to “session.hash_function = 1” for SHA1.
If PHP >= 5.3, set it to session.

hash_function = sha256


session.hash_function = sha512

-> “session.hash_bits_per_character = 5” in php.ini. When the attacker tries to guess the session identifier the ID will be shorter, but uses more characters.
-> Change the default session name from PHPSESSID to something else.
-> Save $_SERVER[‘HTTP_USER_AGENT’] in session and check in every request for user agent.

Defend attackers 🙂

FULL-TEXT search using MYSQL

MySQL provides a wonderful way (Full-text Search) of implementing a little search engine in your website. All you have to do is to have MySQL 4.x and above.


MySQL allow text searching by using the LIKE and regular expression. But, these methods have some limitations like:

  • Performance: MySQL need to scan whole table to find the exact text based on pattern in the LIKE  or pattern in the regular expressions.
  • Flexible search: It is difficult to have flexible search query e.g., to find product whose description contains car but not classic.
  • Relevance ranking: No way to specify which row in the result set that is more relevant

Features of MySQL full-text search:

  • Native SQL-like interface: you use SQL-like statement to use the full-text search.
  • Searches are not case sensitive
  • Fully dynamic index: MySQL automatically index the text column whenever the data changes. You don’t need to run the index periodically.
  • It does not take much memory to store the index.
  • It is fast to search based on complex search query.

SearchGet Started

Before we start, it’s important to know about these keywords:


The MATCH function is used to specify the column names that identify your FULLTEXT collection. The column list inside the MATCH function must exactly match that of the FULLTEXT index definition, unless your search in boolean mode (see below).


The AGAINST function is where your full text search query goes. Besides the default natural language search mode, you can perform boolean mode searches, and use query expansion.

Lets start with some sample table and query:

CREATE TABLE articles (
    title VARCHAR(200),
    body TEXT,
    FULLTEXT (title,body)
// Insert some data into table

INSERT INTO articles (title,body) VALUES
('MySQL Tutorial','DBMS stands for DataBase ...'),
('How To Use MySQL Well','After you went through a ...'),
('Optimizing MySQL','In this tutorial we will show ...'),
('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'),
('MySQL vs. YourSQL','In the following database comparison ...'),
('MySQL Security','When configured properly, MySQL ...');

Here two types of search are possible:

  • Natural Language Full-Text Searches
  • Boolean Full-Text Searches

Natural Language Full-Text Searches

SELECT * FROM articles
    WHERE MATCH (title,body) AGAINST ('database');

This query will fetch all the records which has database keyword.

Boolean Full-Text Searches

SELECT * FROM articles WHERE MATCH (title,body)

In above query you see that I have added IN BOOLEAN MODE in against(). This query will fetch all the records which has MySQL keyword but not YourSQL keyword. (+ and – that we have specified before the keywords)

+ stands for AND
- stands for NOT
[no operator] implies OR


Not all storage engines support full-text searching. In MySQL, only MyISAM and InnoDB storage engines support full-text search. The MATCH() column list must match exactly the column list in some FULLTEXT index definition for the table, unless this MATCH() is IN BOOLEAN MODE. Boolean-mode searches can be done on non-indexed columns, although they are likely to be slow.

Enjoy Coding! 🙂


Parallel Download Link

Parallel vs Serial – fighting continues.

Note that for smaller files it doesn’t matter much. But in case of bigger files it really does.

Case 1: 4113-thumb
Lets say we have download links for songs. So the user may want to download one by one, as in this way single file download is faster and user can start listening while other are getting download.

Case 2:
Now suppose our download links provide zipped reports. And those reports will be analyzed later. Another example can be your site provide online courses. When a user going through online tutorial he may download all the resources and assignments. In these cases user may want to download all the files parallel.

Generally we use this type of code to implement download functionality.

header('Content-Type: audio/mpeg3');
header('Content-disposition: attachment; filename=' . $filename);
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($path));

Now if you access more than one download link, you may find that when first download is on the process others are not started. After completion of first download second one gets started and so on..

To make all download parallel use this simple trick –


at the top of the method.

What it does?

According to PHP’s session handling, using the default session handler, when a PHP script opens a session it locks it. Subsequent scripts that need to access, it have to wait until the first script is finished with it and unlocks it (which happens automatically at shutdown, or by session_write_close() ). So here session_write_close() simply unlocks the session.

Hope this will help 🙂
