Sort products by 2 attributes in magento

Sort products by 2 attributes in magento

In magento site suppose you have the requirement to sort the product listings by 2 attributes like "in stock" and "popularity"

After some research, it seems to work.

Use the following code given below:

<?php
     $Collection->setOrder(array('attribute1', 'attribute2'), asc); //the setOrder() method accepts an array.
?>

Modified this line in Toolbar.php in the Catalogue/Product/List/ directory.

<?php
 if ($this->getCurrentOrder())
 {
    $this->_collection->setOrder(array($this->getCurrentOrder(), 'in stock'), $this->getCurrentDirection());
 }
?>

Hope this will work!

Enable template path hint in Magento

To enable magento path hint for your magento website

Login into admin section and go to System->Configuration->Advanced->Developer

Inside this, click on "Debug" option.

If the Current Configuration Scope is "Default" (left top), you will be not able to set template path hints for your magento website.

So you have to select the magento website from the dropdown and then change the template Path Hints to "yes" .

Now your template path hint has been enabled. You can view template path hint on the frontend of your website.

if some how due to cache you are not getting the path hint.

Then go to System->Cache management and "flush" or "refresh" the cache.

Magento: Difference between order states and statuses

If you are building website in Magento, you may have noticed that there are two columns insales_flat_order table which are confusing. These are state and status. You might think what is the difference between these two, both having same meaning.

Well, this is not the case. They both are different. State is used by magento to tell if the order is new, processing, complete, holded, closed, canceled, etc.; while Statuses are the one that YOU would be defining at the backend in System -> Order Statuses. Magento displays order STATUSES and not STATES in the backend order detail page to let you know which status is assigned as per your mapping. Remember, multiple statuses can be mapped with one state, while vice versa is not possible.

Consider an example, your customer places an order as Cash on Delivery, you will need something like COD_Pending as the order status so that you know it is not yet paid. Magento will have state new for this, which makes you unpredictable of what kind of transaction is this, COD or Prepaid. The STATUS can be anything, as you define, for your understanding; while STATE is something which Magento needs to understand, internally.

In short, Magento uses order state internally for processing order, whereas order status are used by store owners to understand the exact order flow where one state can be assigned to multiple statuses.

To understand this in detail, have a look at this

How to Override controller in magento / Override controller’s action in magento

Requirement : Some times you may run into situation where you want to override the core functionality of Magento core controllers. So in this case, The best practise is override the controller then override actions or add new actions for custom requirement.

For example you want to override OnepageController.php file and overwride indexAction.

In this example my custom module name space is “MyBlog” and i am going to overwride indexAction Mage_Checkout_OnepageController

Base File Path : app/code/core/Mage/Checkout/controllers/OnepageController.php

To Do the same we have to follow bellow steps.

Step1: We need to create a custom module

File Path : app/etc/modules/

File Name: MyBlog_Checkout.xml

File Content:

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

Step2: Now we have to create bellow files in our custom module

File Path: app/code/local/MyBlog/Checkout/etc/config.xml

Bellow is content for config.xml file

<?xml version="1.0"?>
<config>
     <modules>
       <MyBlog_Checkout>
         <version>0.0.1</version>
       </MyBlog_Checkout>
     </modules>

    <frontend>
        <routers>
            <checkout>
                <args>
                    <modules>
                        <MyBlog_Checkout before="Mage_Checkout">MyBlog_Checkout</MyBlog_Checkout>
                    </modules>
                </args>
            </checkout>
        </routers>
    </frontend>
</config>

Bellow is content for OnepageController.php

File Path : app/code/local/MyBlog/Checkout/controllers/OnepageController.php

<?php
 
require_once 'Mage/Checkout/controllers/OnepageController.php';
class MyBlog_Checkout_OnepageController extends Mage_Checkout_OnepageController {

     public function indexAction()
    {
        echo "Great! You are in MyBlog checkout controller section";
