Magento は、Mage_Customer_Model_Resource_Customer クラスで顧客の電子メールの重複をチェックしました。それを見てください。この機能が見つかります。
protected function _beforeSave(Varien_Object $customer)
{
parent::_beforeSave($customer);
if (!$customer->getEmail()) {
throw Mage::exception('Mage_Customer', Mage::helper('customer')->__('Customer email is required'));
}
$adapter = $this->_getWriteAdapter();
$bind = array('email' => $customer->getEmail());
$select = $adapter->select()
->from($this->getEntityTable(), array($this->getEntityIdField()))
->where('email = :email');
if ($customer->getSharingConfig()->isWebsiteScope()) {
$bind['website_id'] = (int)$customer->getWebsiteId();
$select->where('website_id = :website_id');
}
if ($customer->getId()) {
$bind['entity_id'] = (int)$customer->getId();
$select->where('entity_id != :entity_id');
}
$result = $adapter->fetchOne($select, $bind);
if ($result) {
throw Mage::exception(
'Mage_Customer', Mage::helper('customer')->__('This customer email already exists'),
Mage_Customer_Model_Customer::EXCEPTION_EMAIL_EXISTS
);
}
// set confirmation key logic
if ($customer->getForceConfirmed()) {
$customer->setConfirmation(null);
} elseif (!$customer->getId() && $customer->isConfirmationRequired()) {
$customer->setConfirmation($customer->getRandomConfirmationKey());
}
// remove customer confirmation key from database, if empty
if (!$customer->getConfirmation()) {
$customer->setConfirmation(null);
}
return $this;
}
顧客の電子メールの重複を許可する場合は、このコードをコメント アウトすることができます。
$adapter = $this->_getWriteAdapter();
$bind = array('email' => $customer->getEmail());
$select = $adapter->select()
->from($this->getEntityTable(), array($this->getEntityIdField()))
->where('email = :email');
if ($customer->getSharingConfig()->isWebsiteScope()) {
$bind['website_id'] = (int)$customer->getWebsiteId();
$select->where('website_id = :website_id');
}
if ($customer->getId()) {
$bind['entity_id'] = (int)$customer->getId();
$select->where('entity_id != :entity_id');
}
$result = $adapter->fetchOne($select, $bind);
if ($result) {
throw Mage::exception(
'Mage_Customer', Mage::helper('customer')->__('This customer email already exists'),
Mage_Customer_Model_Customer::EXCEPTION_EMAIL_EXISTS
);
}
または、顧客リソースを書き直した方がよいでしょう。私自身、書き直すことをお勧めします。お役に立てれば。
