Improve this question

I am trying to achieve something like this:

When adding new product, The field for "Set Product as New from Date" will be auto filled with Same day date (Current date) and "Set Product as New to Date"= 1/2/3 months from that date.

I found similar post which advise to create observer event Link(automatic add the product's Set Product as New from Date) . But its not very in detail. Can please someone help me step by step on how to do this?

I want to know how to do that - From start to End - Step by Step.

Thanks

In order to do what you want you'd have to create a simple module that would hook into event called catalog_product_save_before.

In that observer you'd have to check if product's new by looking at protected property _origData. If that property would be NULL then set the values for product's properties newsFromDate and newsToDate. Values of those dates would be best to initialize in your class _construct() method.

I'll assume that namespace of this module is my nickname, and the module is called NewProductAuto.

Directories:

• app/code/local/Versedi/NewProductAuto/Model
• app/code/local/Versedi/NewProductAuto/etc/
• app/code/local/Versedi/NewProductAuto/Helper/

Files:

• app/etc/modules/Versedi_NewProductAuto.xml
• app/code/local/Versedi/NewProductAuto/Model/Observer.php
• app/code/local/Versedi/NewProductAuto/etc/config.xml
• app/code/local/Versedi/NewProductAuto/Helper/Data.php

Two most important files are Observer.php and module's configuration - config.xml, I'll ommit the rest hoping that it's self explanatory or that you can find information about that in a number of places over the internet.

app/code/local/Versedi/NewProductAuto/Model/Observer.php First we have to declare our class which will be named: Versedi_NewProductAuto_Model_Observer and will extend Mage_Core_Model_Abstract.

In that class declare two protected properties - $productNewFromDate and $productNewToDate and two methods - _construct() and setProductNewFromDateToday().

We can set variables with current date when the class is initialized or simply when the product is actually new, I prefer to do that in _construct() method but it's not necessary.

public function _construct() { $now = date('d-m-Y', time()); $this->productNewFromDate = $now; $this->productNewToDate = new \DateTime($now); $this->productNewToDate = $this->productNewToDate->add(new DateInterval('P3M'))->format('d-m-Y'); }

What we do in above code block? We're setting new variable $now with time in number format converted to date using php internal function date(). We're assigning that date to our protected property productNewFromDate. Next thing is initializing a DateTime object to which we then add new DateInterval with value of 3 months (one day - P1D, one month - P1M). This value though still needs converting to our target format - d-m-Y.

 
    /**
     * @param Varien_Event_Observer $observer
     *
     */ 
    public function setProductNewFromDateToday(Varien_Event_Observer $observer)
    {
        $product = $observer->getEvent()->getProduct();
        if ($product->getOrigData() === NULL) { // Only if product is new - no original data exists
            $product->setNewsFromDate($this->productNewFromDate);
            $product->setNewsToDate($this->productNewToDate);
        }
    }

What we do in above code block? When the event is fired our function is called and an observer is passed to it. The observer can retrieve object/class/entity/data from the event that takes place. Our name of the function must be exactly same (lettercase sensitive) as stated inside config.xml node <method>setProductNewFromDateToday</method> which I'll describe few lines below. Next thing is checking if the product is actually new or if it's being edited, we do that with this:

if ($product->getOrigData() === NULL) {

The rest is self explanatory.

config.xml Most important thing in the config.xml is declaring that we want to hook into event. We do that creating an <events></events> node, in which as you can suspect we're typing the name of event that we want to catch on. I've described each node in codeblock below:

<events> <catalog_product_save_before><!-- name of the event that we're catching/hooking --> <observers> <versedi_newproductauto_handler> <!-- name of the observer --> <type>model</type> <!-- class method call type; valid are model, object and singleton --> <class>Versedi_NewProductAuto_Model_Observer</class><!-- name of observer's class --> <method>setProductNewFromDateToday</method> <!-- name of the function in observer that we're calling when the event is fired --> <args /> </versedi_newproductauto_handler> </observers> </catalog_product_save_before> </events> </global>

Since we're using an Observer model we need to declare the model inside config.xml too:

<models> <versedi_newproductauto> <class>Versedi_NewProductAuto_Model</class> <resourceModel>versedi_newproductauto_resource</resourceModel> </versedi_newproductauto>

That's basically it.
