I've been trying to programmatically create a salesrule that applies a fixed discount if the given conditions are met:

  • The customer email is emailtest@test.com
  • The skuvisible (custom product attribute in our Magento) is 46306

For that, I came up with this code:

$conditions['conditions']['1'] = array(
    'type' => 'salesrule/rule_condition_combine',
    'aggregator' => 'all',
    'value' => '1',
    'new_child' => ''
);
$conditions['conditions']['1--1'] = array(
    'type' => 'amrules/rule_condition_customer',
    'attribute' => 'email',
    'operator' => '==',
    'value' => 'emailtest@test.com'
);
$conditions['conditions']['1--2'] = array(
    'type' => 'salesrule/rule_condition_product_found',
    'aggregator' => 'all',
    'value' => '1',
    'new_child' => ''
);
$conditions['conditions']['1--2--1'] = array(
    'type' => 'salesrule/rule_condition_product',
    'attribute' => 'skuvisible',
    'operator' => '==',
    'value' => '46306'
);

$model = Mage::getModel('salesrule/rule');

$data = array(
    'name' => "rule-name",
    'description' => "rule-name",
    'is_active' => '1',
    'website_ids' => array(126),
    'coupon_type' => Mage_SalesRule_Model_Rule::COUPON_TYPE_SPECIFIC,
    'uses_per_customer' => 1,
    'from_date' => date('Y-m-d', strtotime('-3 hours')),
    'to_date' => date('Y-m-d', strtotime('-3 hours')),
    'is_rss' => '0',
    'simple_action' => Mage_SalesRule_Model_Rule::CART_FIXED_ACTION,
    'discount_amount' => 455,
    'discount_qty' => 0,
    'stop_rules_processing' => '1',
    'store_labels' => array(0 => "AllwaysOn-Other"),
    'salesrule_type' => 'default',
    'conditions' => $conditions['conditions']
);

$model->loadPost($data);
$model->save();

However, when I run it, I get the following error:

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`clara`.`salesrule_product_attribute`, CONSTRAINT `FK_SALESRULE_PRODUCT_ATTRIBUTE_RULE_ID_SALESRULE_RULE_ID` FOREIGN KEY (`rule_id`) REFERENCES `salesrule` (`rule_id`) ON DELETE CASCADE ON UPD)INSERT INTO `salesrule_product_attribute` () VALUES () Array

I don't get why this happens, because when I try to create the same rule using the admin panel with the same conditions, the error doesn't appear.

I finally figured it out! Turns out certain salesrule conditions require you to provide a customer_group_ids, otherwise Magento will attempt to perform an empty insert on salesrule_product_attribute table.

Therefore, the working code is as follows:

$customer_group = new Mage_Customer_Model_Group();
$allGroups = $customer_group->getCollection()->toOptionHash();
$groups = array();
foreach ($allGroups as $key => $value) {
    $groups[] = $key;
}

$conditions['conditions']['1'] = array(
    'type' => 'salesrule/rule_condition_combine',
    'aggregator' => 'all',
    'value' => '1',
    'new_child' => ''
);
$conditions['conditions']['1--1'] = array(
    'type' => 'amrules/rule_condition_customer',
    'attribute' => 'email',
    'operator' => '==',
    'value' => 'emailtest@test.com'
);
$conditions['conditions']['1--2'] = array(
    'type' => 'salesrule/rule_condition_product_found',
    'aggregator' => 'all',
    'value' => '1',
    'new_child' => ''
);
$conditions['conditions']['1--2--1'] = array(
    'type' => 'salesrule/rule_condition_product',
    'attribute' => 'skuvisible',
    'operator' => '==',
    'value' => '46306'
);

$model = Mage::getModel('salesrule/rule');

$data = array(
    'name' => "rule-name",
    'description' => "rule-name",
    'is_active' => '1',
    'website_ids' => array(126),
    'coupon_type' => Mage_SalesRule_Model_Rule::COUPON_TYPE_SPECIFIC,
    'uses_per_customer' => 1,
    'from_date' => date('Y-m-d', strtotime('-3 hours')),
    'to_date' => date('Y-m-d', strtotime('-3 hours')),
    'is_rss' => '0',
    'simple_action' => Mage_SalesRule_Model_Rule::CART_FIXED_ACTION,
    'discount_amount' => 455,
    'discount_qty' => 0,
    'stop_rules_processing' => '1',
    'store_labels' => array(0 => "AllwaysOn-Other"),
    'salesrule_type' => 'default',
    'customer_group_ids' => $groups,
    'conditions' => $conditions['conditions']
);

$model->loadPost($data);
$model->save();
