What magento method I can use to stop the checkout button to function until a certain condition its true?
basically is a user has deleted a product on basket while he must not checkout until two products are on the basket
public function deleteAction()
{
parent::deleteAction();
if($this->_getCart()->getQuote()->getItemsCount() == 1) {
$this->addErrorMessage('Please remove one voucher. Or add one More infant milk product');
}
}
This is quite easy to accomplish using the config flag checkout/options/onepage_checkout_enabled:
public function deleteAction()
{
parent::deleteAction();
if($this->_getCart()->getQuote()->getItemsCount() == 1) {
Mage::app()->getStore()->setConfig('checkout/options/onepage_checkout_enabled',0);
}
}
A side note:
It's not really necessary to rewrite the controller here, as you could handle it in a postdispatch controller observer action:
<events>
<controller_action_postdispatch_checkout_cart_delete>
<observers>
<yourmodule_postdispatch_delete>
<class>yourmodel/observer</class>
<method>deletePostdispatch</method>
</yourmodule_postdispatch_delete>
</observers>
</controller_action_postdispatch_checkout_cart_delete>
</events>
And the observer method would look like:
public function deletePostdispatch($observer)
{
if(Mage::getSingleton('checkout/session')->getQuote()->getItemsCount()==1){
Mage::app()->getStore()->setConfig('checkout/options/onepage_checkout_enabled',0);
}
}
HTH, Cheers!

Which controller in Magento do I need to override if I want to redirect a certain product view page to another url?
I'd like to use the following code for redirection. Is there any more Magento-like way of doing it?
if($this->getProductId() == 10) {
header("Location: /mymodule");
die();
}
Magento Admin has a feature for this under Catalog > URL Rewrite Management. Create a new product rewrite with these steps:
Click the Add URL Rewrite button at top right.
Select “Custom” from Create URL Rewrite.
Choose the appropriate Store.
Set Request Path to something like this catalog/product/view/id/10 (assuming 10 is the ID of your product).
Set Target Path to whatever route or URL you want to send the request to.
Set Redirect to probably “Temporary (302)”.
Found a solution. Might not be the best one but it works:
Observer.php:
class Namespace_Mymodule_Model_Observer {
public function redirect(){
//request object
$request = Mage::app()->getRequest();
//only redirect in the frontend/catalog
$storeId = Mage::app()->getStore()->getId();
if(in_array($request->getModuleName(), array("catalog")) && $storeId != 0) {
$response = Mage::app()->getResponse();
$params = Mage::app()->getRequest()->getParams();
//check the product id
if($params[id] == 10) {
return $response->setRedirect("/mymodule", 301)->sendHeaders();
}
}
}
}
And the config.xml in the global/events section:
<controller_action_predispatch>
<observers>
<namespace_mymodule_observer>
<type>singleton</type>
<class>namespace_mymodule/observer</class>
<method>redirect</method>
</namespace_mymodule_observer>
</observers>
</controller_action_predispatch>
I believe a better approach is to actually utilize the observer event since all you need is included here already. Also, the answer does not differentiate between products and categories since in_array($request->getModuleName(), array("catalog")) would be true for both.
class Namespace_Mymodule_Model_Observer {
public function redirect(Varien_Event_Observer $observer) {
$actionName = $observer->getEvent()->getControllerAction()->getFullActionName();
$productId = $observer->getEvent()->getControllerAction()->getRequest()->getParam('id');
if($actionName == 'catalog_product_view' && $productId == 10) {
$response = $observer->getEvent()->getControllerAction()->getResponse();
$response->setRedirect('/mymodule', 301)->sendHeaders();
}
}
}
We have been using a third party to pack and ship our packages. Therefore we don't see all orders that pass by anymore.
But there are several products that we have to supply manually ourselves, such as a digital gift card. Is there a possibility to have Magento send us an email when a specific SKU has been ordered by a customer? For instance to inform us that we need to create a gift card for a customer?
I don't want to see every order in our emailbox, just with some specific SKU's in it.
Thanks,

Yes this can be achieved with a custom module. Create your module and add an event observer to it's config.xml;
<events>
<checkout_onepage_controller_success_action>
<observers>
<copymein>
<type>singleton</type>
<class>dispatcher/observer</class>
<method>ccMyEmail</method>
</copymein>
</observers>
</checkout_onepage_controller_success_action>
</events>
Then in Model/Observer.php declare your function;
public function ccMyEmai($observer) {
$order_ids = $observer->getData('order_ids');
if(isset($order_ids)) {
foreach ($order_ids as $order_id) :
$sendToMe = false;
$order = Mage::getModel('sales/order')->load($order_id);
if (isset($order)) {
$orderItems = $order->getAllItems();
foreach ($orderItems as $_item) {
$product = Mage::getModel('catalog/product')->load($item->getData('product_id'));
if($product->getSku() == ('123' || '234' || '345')) { // Your SKUs
$sendToMe = true;
}
}
}
if($sendToMe) {
$mail = Mage::getModel('core/email');
$mail->setToName('Your name');
$mail->setToEmail('your#email.com');
$mail->setBody('Order number '.$order->getIncrementId().' has items that need action');
$mail->setSubject('Order '.$order->getIncrementId().' needs attention');
$mail->setFromName('Your from name');
$mail->setFromEmail('your#siteemail.com');
$mail->setType('text');
try {
$mail->send();
} catch (Exception $e) {
Mage::log($e);
}
}
endforeach;
}
}
Just a note that it would be more efficient to create a product attribute that isnt visible on the frontend that defines whether a product requires your attention - something along the lines of needs_attention Yes/No, then scan the ordered products for a yes value in that attribute. Much more manageable than hard coding the SKU's you are looking for ;)
You might create a custom module for this functionality. So in the new module, you have to hook Observer event: checkout_onepage_controller_success_action.
You can do like following as :
<checkout_onepage_controller_success_action>
<observers>
<xxx_checkout_success>
<type>singleton</type>
<class>[Your Module Name]/observer</class>
<method>sendEmailToCustomerForSales</method>
</xxx_checkout_success>
</observers>
</checkout_onepage_controller_success_action>
And, in this sendEmailToCustomerForSales() method, it can send an email to the customer according to a specific SKU.
Please refer this code:
public function sendEmailToCustomerForSales($observer) {
$orderId = (int)current($observer->getEvent()->getOrderIds());
$order = Mage::getModel('sales/order')->load($orderId);
$itemCollection = $order->getItemsCollection();
foreach($itemCollection as $item) {
$_product = Mage::getModel('catalog/product')->load($item->getProductId());
if($_product->getSku() == '[Your specific sku]') {
/*send an email to the customer*/
}
}
}
Event only runs once. I am adding custom value in quote after product add in cart through observer on event checkout_quote_init
it works fine but if customer is logged in and place order then in first order value is inserted well in quote but in second time observer is not runing.
<checkout_quote_init>
<observers>
<youva_custom>
<type>singleton</type>
<class>custom/observer</class>
<method>setqoutevalue</method>
</youva_custom>
</observers>
</checkout_quote_init>
public function setqoutevalue($observer) {
$event = $observer->getEvent();
$_quote = $event->getQuote();
$_quote->setCustomevalue($customevalue);
$_quote->save();
}
If you take a look at the code that dispatches the event you are using you will see this (Mage_Checkout_Model_Session::getQuote()):
if (!$this->getQuoteId()) {
if ($customerSession->isLoggedIn() || $this->_customer) {
$customer = ($this->_customer) ? $this->_customer : $customerSession->getCustomer();
$quote->loadByCustomer($customer);
$this->setQuoteId($quote->getId());
} else {
$quote->setIsCheckoutCart(true);
Mage::dispatchEvent('checkout_quote_init', array('quote'=>$quote));
}
}
This means that the event is dispatched only when the quote is created. and only when the user is not logged in. This means that if there is already a quote id in the session the event won't get dispatched.
You may want to use a different event. For example checkout_cart_product_add_after
I have a special case where users have to sign up for an account via the account sign up page (e.g. /customer/account/create/). Upon completion, and in the event that they have a product in the cart, I need to redirect them back to the checkout screen.
I currently have an observer in place that listens to the customer_register_success event. The observer upgrades the users account to a membership group via this code:
class Hatclub_MembershipHandler_Model_Observer {
// members group id
const GROUP_ID = 4;
// called when a customer registers for the site
public function registrationSuccess(Varien_Event_Observer $observer) {
// extract customer data from event
$customer = $observer->getCustomer();
// a cookie should have been set with the membership id
if (isset($_COOKIE['membership_account_id'])) {
$customer
->setGroupId(self::GROUP_ID)
->setRmsId($_COOKIE['membership_account_id']);
}
return $this;
}
}
Is there another event that I can listen to that is better suited for what I want to do? I have a redirect_to cookie that is available as well if that helps.
After much trial and error, I came across a solution. Since I'm already using the customer_register_success event and modifying user data with my observer, I had to use another event called customer_save_after and it worked like a charm.
config.xml event block
<customer_save_after>
<observers>
<customer_session_observer>
<class>hatclub_membership_handler/observer</class>
<method>customerSave</method>
<type>singleton</type>
</customer_session_observer>
</observers>
</customer_save_after>
observer.php method
public function customerSave() {
// set redirect url from cookie, default to null
$redirect_url = (isset($_COOKIE['redirect_url']))
? isset($_COOKIE['redirect_url']) : null;
// if a redirect url was specified
if (isset($redirect_url)) {
// remove cookie to prevent infinite loop
unset($_COOKIE['redirect_url']);
// redirect to provided url
Mage::app()->getResponse()
->setHeader('Location', $redirect_url)
->sendHeaders();
}
}
The redirect within an observer was a bit of a struggle, but I managed to accomplish it using
Mage::app()->getResponse()
->setHeader('Location', $redirect_url)
->sendHeaders();
Suggestions and criticism welcome.
Why are there no events dispatched on or around the newsletter subscription/un-subscription process either in the customer or newsletter modules.
The only alternative i am faced with at the moment is to use a rewrite for the subscriber model to fit some code in around here.
Does anyone else have a good alternative to this - or am I missing something
I encountered a situation where I needed to listen for subscription/unsubscription events. I encountered this question and thought I would leave this solution here for anyone that may need it:
By adding an observer to the event newsletter_subscriber_save_before in your config.xml:
<global>
....
<events>
....
<newsletter_subscriber_save_before>
<observers>
<your_unique_event_name>
<class>yourgroupname/observer</class>
<method>newsletterSubscriberChange</method>
</your_unique_event_name>
</observers>
</newsletter_subscriber_save_before>
</events>
</global>
You can then call getSubscriber() (in the context of $observer->getEvent(), see next code block) in your observer to get the Mage_Newsletter_Model_Subscriber model that allows you get data about the subscriber. This works for occurrences of subscription and unsubscriptions.
public function newsletterSubscriberChange(Varien_Event_Observer $observer) {
$subscriber = $observer->getEvent()->getSubscriber();
//now do whatever you want to do with the $subscriber
//for example
if($subscriber->isSubscribed()) {
//...
}
//or
if($subscriber->getStatus() == Mage_Newsletter_Model_Subscriber::STATUS_SUBSCRIBED) {
//...
} elseif($subscriber->getStatus() == Mage_Newsletter_Model_Subscriber::STATUS_UNSUBSCRIBED) {
//..
}
}
So it turns out this is really easy. These model events are super powerful and let you do things like this super easily. Can't turn down free functionality!
For quick reference, here is what data the Mage_Newsletter_Model_Subscriber model provides (1.7)
Here's what just worked for me on 1.7.0.2. I know this thread is old, but posting it here in case it can help anyone (since there's not a lot of info about this event out there):
*NOTE: Replace myco_myextension with your extension's unique name:*
In config.xml:
<newsletter_subscriber_save_commit_after>
<observers>
<myco_myextension_model_observer>
<class>Myco_Myextension_Model_Observer</class>
<method>subscribedToNewsletter</method>
</myco_myextension_model_observer>
</observers>
</newsletter_subscriber_save_commit_after>
In Observer.php:
public function subscribedToNewsletter(Varien_Event_Observer $observer)
{
$event = $observer->getEvent();
$subscriber = $event->getDataObject();
$data = $subscriber->getData();
$statusChange = $subscriber->getIsStatusChanged();
// Trigger if user is now subscribed and there has been a status change:
if ($data['subscriber_status'] == "1" && $statusChange == true) {
// Insert your code here
}
return $observer;
}
The newsletter/subscriber model is a normal Magento model from the looks of it, so it should still dispatch some events from the upstream classes. Take a look at something like newsletter_subscriber_create_after and newsletter_subscriber_delete_after for some possible event hooks to use.
the newsletter modul hooks to event: customer_save_after
