Compare products. Side element does not display products.

Question

When I click "Add to compare" on a product, a message appears stating that "such and such a product has been successfully added to the comparison list", however, the side panel "Compare Products" displays "You have no items to compare." If I do print_r($this->helper('catalog/product_compare')->getItemCount()) in template/catalog/product/compare/sidebar.phtml , " 0 " is returned.

Why doesn't the sidebar show product comparison?

Information: Magento version 1.4.0.1 It seems that the sessions are working, and I can add products to the basket, and they will remain in the basket when navigating the site.

Thanks Ben

Found a solution after several hours of searching: One or more indexes needed to be rebuilt.

In case anyone else encounters this problem, the ability to start index recovery is located in the administrator’s interface by going to the System menu and choosing Manage Indexes.

I made changes to this file:

Application \ Code \ Kernel \ Mage \ Catalog \ Helper \ Product \ Compare.php

from line 215. I commented on the output of if.

 /* if (!$this->_getSession()->hasCatalogCompareItemsCount()) { $count = 0; } else { */ 

and in line 235. Commented on the closing bracket:

 /*}*/ 

It worked for me.

I think this is the solution.

Another reason you can compare comparison tools is because of some site optimizations, such as disabling certain events, such as

controller_action_predispatch controller_action_postdispatch

Check etc / local.xml

 <frontend> <events> <controller_action_predispatch> <observers><log><type>disabled</type></log></observers> </controller_action_predispatch> <controller_action_postdispatch> <observers><log><type>disabled</type></log></observers> </controller_action_postdispatch> </events> </frontend> 

and delete

  <controller_action_predispatch> <observers><log><type>disabled</type></log></observers> </controller_action_predispatch> <controller_action_postdispatch> <observers><log><type>disabled</type></log></observers> </controller_action_postdispatch>

 /** * Retrieve count of items in compare list * * @return int */ public function getItemCount() { if (!$this->_getSession()->hasCatalogCompareItemsCount()) { $this->calculate(); } return $this->_getSession()->getCatalogCompareItemsCount(); }

I have the same problem, and because of my browser (chrome) I switch to firefox, and the Add to Compare option works fine.
