Magento prevent duplicate product & category url's - magento

How can the admin user be informed when he create a product or category that the url key already exist with an error message and block the product/category creation until he change the product/category name or url key?
Thanks.

I have implemented a solution for this issue. I will post here a summary answer, if somebody have some questions, please ask.
Category: create an observer and for 'catalog_category_save_before' event add a url check validation, can be done with direct sql, something like:
$query = " SELECT value_id
FROM catalog_category_entity_varchar
WHERE value = '" . $urlKey . "' AND attribute_id = (
SELECT attribute_id
FROM eav_attribute
WHERE entity_type_id = 3 AND attribute_code = 'url_key')
";
Products: 2 things here...one to check the url when it's created from product name (if url key is empty on save product) and another one if url key is specified on product save:
add a backend model for the product 'name' attribute and on validate() method check for duplicate value if url key is not set, something like:
$urlKey = $object->getData('url_key');
if ($urlKey) {
return true;
}
if (!$this->getAttribute()->getEntity()->checkAttributeUniqueValue($this->getAttribute(), $object)) {
throw Mage::exception('Mage_Eav',
Mage::helper('eav')->__('The value of this attribute must be unique if you do not set explicit URL Key')
);
}
ovewrite in config.xml the urlkey backend model and the same like for 'name' attribute, add under validate() method the duplicate check, like:
if (!$this->getAttribute()->getEntity()->checkAttributeUniqueValue($this->getAttribute(), $object)) {
$label = $this->getAttribute()->getFrontend()->getLabel();
throw Mage::exception('Mage_Eav',
Mage::helper('eav')->__('The value of attribute "%s" must be unique', $label)
);
}

Magento: where are catalog filter's (url get parameter's) handled in magento? and where is sql request made to fetch the result?

Magento currently handles only one filter parameter per category .
I want the filter to handle more than one parameter's for the same category.
eg, Suppose I choose 2 colors red and black in the filter using a checkbox for ex, and then click submit button (which I have added), then I want the page to display results for product's having color red or black.
For this, I want to know :
Where are GET parameter's for any filtering process handled in magento.
Where is the sql request made to fetch the results of filtering process.
So that I could handle more than one filter parameter's and display the results.
Any help or suggestion would be of great help.
Thanks in advance..
For your example scenario, you are filtering using attribute color having its attribute ID. The resource model is responsible to execute the SQL operations being performed on any attribute selection.
Go to file app/code/core/Mage/Catalog/Model/Resource/Layer/Filter/Attribute.php
public function applyFilterToCollection($filter, $value)
{
$collection = $filter->getLayer()->getProductCollection();
$attribute = $filter->getAttributeModel();
$connection = $this->_getReadAdapter();
$tableAlias = $attribute->getAttributeCode() . '_idx';
$conditions = array(
"{$tableAlias}.entity_id = e.entity_id",
$connection->quoteInto("{$tableAlias}.attribute_id = ?", $attribute->getAttributeId()),
$connection->quoteInto("{$tableAlias}.store_id = ?", $collection->getStoreId()),
$connection->quoteInto("{$tableAlias}.value = ?", $value)
);
$collection->getSelect()->join(
array($tableAlias => $this->getMainTable()),
implode(' AND ', $conditions),
array()
);
return $this;
}
In the above function, when you print the collection and exit it before return using,
$collection->printlogquery(true);
you will see the SQL query generated to fetch the results of filtering process.
You can modify this resource model in your local and using INNER JOIN change the SQL query to work for multiple attribute values.

Adding new customer from backend not inserting store id

I am using magento 1.7.0.2. I am having issue regarding store id. When I add new customer from the frontend by sign up, it adds the store id in the "Customer Entity" table. However, when I try to manually add a customer using the backend inserts "0" rather than the 'store id' in the "Customer Entity" table.
How can I get the store id of the customer when adding a customer by admin?
How to set option in backend to insert store id manually in "Customer Entity" table via backend?
Is it required to set new field 'select store'?
It is simple.
go to /app/code/core/Mage/Adminhtml/controllers/CustomerController.php
and just before //send welcome email part
// Mage::dispatchEvent('adminhtml_customer_prepare_save', array(
// 'customer' => $customer,
// 'request' => $this->getRequest()
// ));
And put following code there.
$storeId = $customer->getSendemailStoreId();
Mage::app()->setCurrentStore($storeId);
$customer->save();
That's it now you can choose store from backend and will also be inserted in to customer_entity table.

Replacing "product name" with "Item + productId" when product is added in Magento via admin panel

I want to auto generate product names in Magento.
When I'm going to add a product, for the product name I will type some string.
When I save the product, I want the product name to be automatically generated such that the product name becomes Item."productId".
Answering assuming that OP wants to incorporate the auto-increment value from the entity table into business data. This is generally not a great idea.
This is an interesting task which can be easily accomplished with Magento's EAV implementation - particularly when working in the catalog module. First, some background.
When an EAV entity is saved, it has a nice, neat array of key => value pairs which represent the attributes and attribute values for that entity:
Mage_Catalog_Model_Product->_data['attribute_code'] = 'attribute value';
During the save process, the EAV resource model takes this array and iterates over it. For each attribute, identified by its code (attribute_code in the above example) and its entity (catalog_product in the case of products), the configuration for the attribute itself is loaded. Of particular importance is the "backend model" for an attribute, as it is invoked to do pre- and post-processing of/relating to the value.
In the current case, there is a piece of information which will not be present when we are saving the attribute, at least, not in a way in which we can use it: the new product id. This can be used to adjust the original value as part of the save process.
It's always nice to have an example from the core, so, refer to the price attribute and its backend model, Mage_Catalog_Model_Product_Attribute_Backend_Price which can be seen in the eav_attribute table:
SELECT `attribute_code`, `backend_model`
FROM `eav_attribute`
LEFT JOIN `eav_entity_type` USING (`entity_type_id`)
WHERE `attribute_code` = 'price';
#+----------------+-----------------------------------------+
#| attribute_code | backend_model |
#+----------------+-----------------------------------------+
#| price | catalog/product_attribute_backend_price |
#+----------------+-----------------------------------------+
#1 row in set (0.00 sec)
When a product is saved, the price attribute's backend_model is instantiated and (in this case) the afterSave() method is called. Incidentally, this method is what updates pricing by conversion rate for website-scoped pricing. This same approach can be used to modify the name attribute.
The following setup script will add the backend model:
<?php
$installer = Mage::getResourceModel('catalog/setup','default_setup');
$installer->startSetup();
$installer->updateAttribute(
'catalog_product',
'name',
'backend_model',
'custom/product_attribute_backend_name'
);
$installer->endSetup();
The corresponding afterSave() method should do the trick:
public function afterSave($object)
{
$value = $object->getData($this->getAttribute()->getAttributeCode());
$origData = $object->getOrigData();
$origValueExist = $origData && array_key_exists($this->getAttribute()->getAttributeCode(), $origData);
//don't do this in case of update
if ($object->getStoreId() != 0 || !$value || $origValueExist) {
return $this;
}
//append autoinc id
$newValue = $value .'.'. $object->getId(); // or whatever
//assume global store, otherwise the stated need is getting weird!
$object->addAttributeUpdate($this->getAttribute()->getAttributeCode(), $newValue, 0);
return $this;
}
If you're doing this from the admin panel product edit screen, you're going to have to remove the "Required" class from the "Name" field so you can save it without the name. This means overriding the Edit form to replace that field specifically. Then you'll have to overload the save-related methods on the product model (or you can do it from the controller), but the child will have to generate the name on save before it goes to the database.
For example:
class Module_Catalog_Model_Product extends Mage_Catalog_Model_Product
{
protected function _beforeSave()
{
parent::_beforeSave();
$productName = 'Item' . $this->getId();
if (!$this->getId() && !$this->getName())
{
$this->setName('Item Unnamed');
} elseif ($this->getId()) && strcasecmp($this->getName(), $productName) <> 0)
{
$this->setName($productName);
}
}
}
The only problem with this is that it requires two saves. If you want to have it work on the fly, you'll have to do a second save using the _afterSave() method. Or, once again, you can do it from the controller.
I would use a Magento Event to do this:
Since Models in Magento have an event prefixes (just take a look at Mage_Catalog_Model_Product and look for $_eventPrefix, for our current model the eventPrefix is set to catalog_product.
If you now take a look at Mage_Core_Model_Abstract and search for _eventPrefix. You see that eventPrefix are found in _beforeLoad, _afterLoad, _beforeSave, _afterSave and a few others. In these methods you can see an event is dispatched using something as below:
Mage::dispatchEvent($this->_eventPrefix.'_save_before', $this->_getEventData());
This means you have an event available called catalog_product_save_before. With this event you can hook into Magento at that time and do your thing, change the field in this case, and Magento handles the rest.
Take a look at http://www.magentocommerce.com/wiki/5_-_modules_and_development/0_-_module_development_in_magento/customizing_magento_using_event-observer_method for more information how to use these events and turn them into a module. If you don't know how to build modules for Magento and want to learn, there are some awesome on-demand video's for free: http://www.magentocommerce.com/training/on-demand
First I want to thanks to all users which write in the topic. Thanks a lot of guys!
I did it, but I make it easier. (because I have very basic knowledge in Magento and it would toke more time)
So... With my colegues decided to make it with php/jquery/ajax.
First we create one single php file, which return the last id:
<?php
header('Access-Control-Allow-Origin: *');
require_once 'app/Mage.php';
umask(o);
Mage::app('default');
Mage::getSingleton('core/session', array('name'=>'frontend'));
$model = Mage::getModel('catalog/product'); //getting product model
$collection = $model->getCollection(); //products collection
foreach ($collection as $product) //loop for getting products
{
$id=$product->getId();
}
if($id)echo $id+1; //id of product
else{
echo 0;
}
?>
After step one I set the value of input (i.e. I auto generate the name):
if($j('#name').val()=='' && window.location.href.indexOf("admin/catalog_product/new/") > -1) {
$j.post('http://www.website.com/file.php', function(data) {
$j('#name').val('Item №'+data);
});
}
Thanks again for help.
Best Regards,

Update in sales order table - Magento Model

I want to update one field value in magento I am using
$data = array('xxx'=>$xxx);
$orderModel = Mage::getModel('sales/order')->load($orderId)->addData($data);
try {
$orderModel->setId($orderId)->save();
echo "Data updated successfully.";
} catch (Exception $e){
echo $e->getMessage();
}
But it is not working, Any one can suggest me what I am doing the create problem in updating data.
you can do the MAGIC function, get and set function
try directly:
// if your attribute is column named is_active then you can getIsActive() or setIsActive(1)
$orderModel = Mage::getModel('sales/order')->load($orderId)->setYourAttribute($data);
// it means you can set and get column named by ['your_attribute']
try {
$orderModel->setId($orderId)->save();
echo "Data updated successfully.";
} catch (Exception $e){
echo $e->getMessage();
}
hmmm. i don't know why you set the entity_id of sales/order model. but it won't work because the entity_id can be the foreign key on another table, example : sales_flat_order_payment
Your code setId($orderId) looks like you either want to explicitely set an order entity_id (that is, create an order), or you're just not aware of the fact, that you don't need setId($orderId) after loading, if you only want to update the given order.
In case you're trying to create an order: the sales/order model normally does not allow to explicitely set an order's entity_id, because it uses a primary key being auto-incremented by default.
In case you're trying to update an existing order: remove the setId($orderId) from the save() chain.
Second, you need to extend the sales/order model with an xxx attribute first, if you want to be able to save its value to the database.
There are several ways to extend the sales/order model to have a custom attribute. For example you could have your own setup script in your app/code/local/Mycompany/Mymodule/sql/myresource/ folder:
// Mage_Eav_Model_Entity_Setup
$oInstaller = $this;
// Add EAV attribute
$oInstaller->startSetup();
$oInstaller->addAttribute(
'order',
'my_attribute',
array(
'type' => 'int'
)
);
$oInstaller->endSetup();
// Add flat attribute
if (Mage::getVersion() >= 1.1) {
$oInstaller->startSetup();
$oConnection = $oInstaller->getConnection();
$oConnection->addColumn(
$oInstaller->getTable('sales_flat_order'),
'my_attribute',
'TINYINT(1) NOT NULL'
);
$oInstaller->endSetup();
}

Adding a custom field to Magento's subscription module

The newsletter subscription module in Magento has only one field (email) by default. After I add an extra field to the form (say country), how can I get the form data to show up in the Magento back-end and be sent as an email to a preset recipient? Thanks.
If you want to add some custom fields for Magento newsletter subscriber (for example subscriber_name), you should do the following:
Add new column for newsletter_subscriber table
Add text input to newsletter template
Create observer for newsletter_subscriber_save_before event
In the observer you can get your custom field's value from request and assign it to subscriber's object:
public function newsletterSubscriberSave(Varien_Event_Observer $observer)
{
$subscriber = $observer->getEvent()->getSubscriber();
$name = Mage::app()->getRequest()->getParam('subscriber_name');
$subscriber->setSubscriberName($name);
return $this;
}
UPDATE:
Here is the detailed article explaining how to add Country field
Also, I have created a free module, it is available on the GitHub
There are a few things that you need to take care of to make this work:
Add a new column for your data to the appropriate database table
Make sure that Magento saves your new field to the database
Present the data in the admin backend
Record the data when you get a new newsletter subscription
Here's how you can do all those things:
Ad. 1)
Using phpMyAdmin, MySQL command line, or whatever is your preferred DB manipulation method, add a new column "country" as, say, varchar(100) to the newsletter_subscriber table.
Ad. 2)
Magento will automatically give you access to the new field through the getCountry() and setCountry() methods on the Mage_Newsletter_Model_Subscriber object. The only thing it won't do is save your field back to the DB after it has been changed with code somewhere in the system. To get it saved you need to modify _prepareSave(Mage_Newsletter_Model_Subscriber $subscriber) function found in Mage_Newsletter_Model_Mysql4_Subscriber (app/code/core/Mage/Newsletter/Model/Mysql4/Subscriber.php). Be sure to make a local copy of the file first and not modify the core file. Here's what you need to add:
protected function _prepareSave(Mage_Newsletter_Model_Subscriber $subscriber)
{
$data = array();
$data['customer_id'] = $subscriber->getCustomerId();
$data['store_id'] = $subscriber->getStoreId()?$subscriber->getStoreId():0;
$data['subscriber_status'] = $subscriber->getStatus();
$data['subscriber_email'] = $subscriber->getEmail();
$data['subscriber_confirm_code'] = $subscriber->getCode();
//ADD A NEW FIELD START
//note that the string index for the $data array
//must match the name of the column created in step 1
$data['country'] = $subscriber->getCountry();
//ADD A NEW FIELD END
(...)
}
Ad. 3)
You will need to modify (a local copy of) the file app/code/core/Mage/Adminhtml/Block/Newsletter/Subscriber/Grid.php. The method you are looking for is called _prepareColumns(). In there you will see a series of calls to $this->addColumn(). You need to add a corresponding call for your "Country" field with the following code:
$this->addColumn('country', array(
'header' => Mage::helper('newsletter')->__('Country'),
//the index must match the name of the column created in step 1
'index' => 'country',
'default' => '----'
));
If you want the field to appear at the end of the grid (as the last column) add it as the last call, otherwise, squeeze it between the existing calls exactly where you want it to end up in the admin.
Ad. 4)
This is a part I did not have to do in my customization of the Magento newsletter, so it will be mostly theoretical. The subscription occurs in the controller located at app/code/core/Mage/Newsletter/controllers/SubscriberController.php. Here's the code of the newAction method with my proposed changes:
public function newAction()
{
if ($this->getRequest()->isPost() && $this->getRequest()->getPost('email')) {
$session = Mage::getSingleton('core/session');
$email = (string) $this->getRequest()->getPost('email');
try {
if (!Zend_Validate::is($email, 'EmailAddress')) {
Mage::throwException($this->__('Please enter a valid email address'));
}
$status = Mage::getModel('newsletter/subscriber')->subscribe($email);
if ($status == Mage_Newsletter_Model_Subscriber::STATUS_NOT_ACTIVE) {
$session->addSuccess($this->__('Confirmation request has been sent'));
}
else {
$session->addSuccess($this->__('Thank you for your subscription'));
}
//ADD COUNTRY INFO START
//at this point we may safly assume that subscription record was created
//let's retrieve this record and add the additional data to it
$subscriber = Mage::getModel('newsletter/subscriber')->loadByEmail($email);
//assuming that the input's id is "country"
$subscriber->setCountry((string) $this->getRequest()->getPost('country'));
//don't forget to save the subscriber!
$subscriber->save();
//ADD COUNTRY INFO END
}
catch (Mage_Core_Exception $e) {
$session->addException($e, $this->__('There was a problem with the subscription: %s', $e->getMessage()));
}
catch (Exception $e) {
$session->addException($e, $this->__('There was a problem with the subscription'));
}
}
$this->_redirectReferer();
}
Going through the above steps should take care of the most part of your problem. Let me know how that last part worked out, as I did not have a chance to test it.
Once you have your additional field in the Subscriber object you can do whatever you want with it. I did not really get what you mean by
be sent as an email to a preset recipient
If you can explain that I will try to help you out with this part too.
Edit - how to send a mail when someone subscribes
Just add the following code to the controller after the part which adds country to a subscriber object.
$mail = new Zend_Mail();
$mail->setBodyHtml("New subscriber: $email <br /><br />Country: ".$this->getRequest()->getPost('country'));
$mail->setFrom("youremail#email.com")
->addTo("admin#mysite.com")
->setSubject("Your Subject here");
$mail->send();
Adding to the accepted answer, you can also get away with this a little easier if you're adding a date, datetime, or timestamp-type column.
In my case, I wanted to add a "Subscribed at Date" to my grid. To do this, I wrote my upgrade script, column type being TIMESTAMP and the default value being CURRENT_TIMESTAMP. This way, when the row is added, the current date/time is recorded.
Then, all you have to do is add your block customizations. I'd suggest doing it by extending Magento's grid block rather than doing the local codepool override though. This way, you only need to override _prepareColumns();
Old thread but if someone has the same question, there is a free extension, that adds fields for gender, firstname and lastname and makes it available in the backend grid for export via xml/csv: http://www.magentocommerce.com/magento-connect/extended-newsletter-subscription-for-guests.html
Perhaps you can extend the code to fit your needs.
This is a warning for anyone who's installed the Ebizmarts_MailChimp extension.
It's a great extension. But it adds subscriber_firstname and subscriber_lastname to the newsletter_subscriber table.
If you intend to create these fields, you should either "require" the Ebizmarts_MailChimp extension or check the fields don't exist before your extension creates them.
In the opposite, where you've created them and want to install the the Ebizmarts_MailChimp extension after you've created these fields, you will have to comment out the addColumn code for these two fields during installation.
