I want to run the observer only when the product is created and not when it is updated. I found this discussion: product-creation-and-saving-existing-products and I followed Tim Ramsey's advice.

So I put this in the config.xml

<global>
 <models>
 <wally_logproductupdate>
 <class>Wally_LogProductUpdate_Model</class>
 </wally_logproductupdate>
 </models>
 <events>
 <catalog_product_save_before>
 <observers>
 <wally_logproductupdate>
 <class>wally_logproductupdate/observer</class>
 <method>beforeSave</method>
 <type>singleton</type>
 </wally_logproductupdate>
 </observers>
 </catalog_product_save_before>
 </events>
</global>

and this in Observer.php:

class Wally_LogProductUpdate_Model_Observer

 protected $isNew = false;

 public function beforeSave($observer)
 
 $product = $observer->getEvent()->getProduct();
 if ($product->isObjectNew()) 
 $this->isNew = true;
 
 

 public function afterSave($observer)
 
 $product = $observer->getEvent()->getProduct();
 if ($this->isNew) 
 $name = $product->getName();
 $sku = $product->getSku();
 $price = $product->getPrice();

 Mage::log("[$name ($sku) $price] aggiornato", null, 'product-updates.log'); 
 
 

The problem is that the log file is not updated when a new product is created.

How can i solve?

Log file will not create because afterSave function never called!
you need to call $this->afterSave($observer); after check isNew.

Like:

public function beforeSave($observer)

 $product = $observer->getEvent()->getProduct();
 if ($product->isObjectNew()) 
 $this->afterSave($observer);
 

Note: you can also eliminate $this->isNew = true; flag and direct call $this->afterSave($observer); in if condition!

Try the following:

app/code/local/SR/MagentoCommunity/etc/config.xml

<?xml version="1.0"?>
<config>
 <modules>
 <SR_MagentoCommunity>
 <version>0.0.0.2</version>
 </SR_MagentoCommunity>
 </modules>
 <global>
 <models>
 <sr_magentocommunity>
 <class>SR_MagentoCommunity_Model</class>
 </sr_magentocommunity>
 </models>
 <events>
 <catalog_product_save_before>
 <observers>
 <sr_catalog_product_save_before>
 <class>sr_magentocommunity/observer</class>
 <method>catalogProductSaveBefore</method>
 <type>singleton</type>
 </sr_catalog_product_save_before>
 </observers>
 </catalog_product_save_before>
 <catalog_product_save_after>
 <observers>
 <sr_catalog_product_save_after>
 <class>sr_magentocommunity/observer</class>
 <method>catalogProductSaveAfter</method>
 <type>singleton</type>
 </sr_catalog_product_save_after>
 </observers>
 </catalog_product_save_after>
 </events>
 </global>
</config>

app/code/local/SR/MagentoCommunity/Model/Observer.php

<?php

 public function catalogProductSaveBefore(Varien_Event_Observer $observer)
 
 /** @var Mage_Catalog_Model_Product $product */
 $product = $observer->getEvent()->getProduct();
 if ($product->isObjectNew()) 
 $this->isNew = true;
 

 return $this;
 

 /**

 public function catalogProductSaveAfter(Varien_Event_Observer $observer)

 $product = $observer->getEvent()->getProduct();
 if ($this->isNew) 
 $name = $product->getName();
 $sku = $product->getSku();
 $price = $product->getPrice();
 error_log("[$name ($sku) $price] aggiornato");
 Mage::log("[$name ($sku) $price] aggiornato", null, 'product-updates.log');
 
 return $this;
