Display collection of Shopping cart rules and products categories associated to each rule

Question

I want to check if there is a sales promotion on the product then stick the promotion label on that product on category list page. But I don\'t know how to loop through all

Answer 1

You could pull the getMatchingProductsIds from /app/code/core/Mage/CatalogRule/Model/Rule.php and compare them with the skus displayed on the category list page.

 $catalog_rule = Mage::getModel('catalogrule/rule')->load(1);  // ID of your catalog rule here, or you could leave off ->load(1) and iterate through  ->getCollection() instead
 $catalog_rule_skus = $catalog_rule->getMatchingProductIds();

EDIT

Here's a way to get the serialized conditions:

$rules = Mage::getResourceModel('salesrule/rule_collection')->load();

foreach ($rules as $rule) {
    $conditions = $rule->getConditionsSerialized();
    var_dump($conditions);
}

EDIT 2

There would have to be a better way to do this. The only way I could pull that data was to unserialize then iterate with foreach through each layer. Anyone have any better ideas for this? This works but is very sloppy.

$rules = Mage::getResourceModel('salesrule/rule_collection')->load();

foreach ($rules as $rule) {

  if ($rule->getIsActive()) { 
$conditions = $rule->getConditionsSerialized();
$unserialized_conditions = unserialize($conditions);

$unserialized_conditions_compact = array();

foreach($unserialized_conditions as $key => $value) {
   $unserialized_conditions_compact[] = compact('key', 'value');
}

for ($i=0;$i $value) {
                        foreach($value as $key1 => $value1) {
                                foreach($value1 as $key2 => $value2) {
                                        foreach($value2 as $key3 => $value3) {
                                                $skus[] = explode(",",$value3['value']);
                                        }
                                }
                        }
                }
        }
}
 }

}

var_dump($skus);
