magento showing wrong product count in category

Question

I have a strange issue and seems many are having the same on internet. Below picture will define my issue and also my magento version is 1.7

Answer 1

Hi product count comes from method name loadProductCount which is located at location code/core/Mage/Catalog/Model/Resource/Category/Collection.php

If you will dig in deep this count is coming from a join query between two tables: catalog_category_product and catalog_category_entity

I have fixed this issue by using event observer. you can do the same for time being. And let me know if you find any better solution.

public function deleteCountCategory (Varien_Event_Observer $observer) {
    try {
    $product = $observer->getEvent()->getProduct();
    $productId = $product->getId();                     
    $resource = Mage::getSingleton('core/resource');    
    $writeConnection = $resource->getConnection('core_write');
    $tableName = $resource->getTableName('catalog_category_product');
    $query = "DELETE FROM {$tableName} WHERE product_id = ".(int)$productId;            
    $writeConnection->query($query);            
    } catch (Exception $e) {
        throw $e;                   
    }
    return $this;           
}
