How can I set the value of a given attribute to the same value for all products (efficiently)?
By efficient I mean in one transaction, not having to loop through the entire product collection.
In the past I've used Mage_Catalog_Model_Product_Action for bulk updates on products, and it runs pretty fast
Mage::getSingleton('catalog/product_action')
->updateAttributes($productIds, array('some_attribute' => 'some_value'), 0)
But it requires you specify which product ids you're updating, creating a huge WHERE entity_id IN(...) clause in the MySQL statement. Is there a way to do this for everything?
I had same problem before, when I added 11096 product(downloadable products) in my store then client told me to add new attributes in product so i create 1 attribute (Type is Yes/No) and set to attribute set. Now my problem is how can iIedit all product and set that attribute yes or not. If I don't set then value is null so I wrote few line code.
Please check this code may be it'll helpful to you.
$ProductId = Mage::getResourceModel('catalog/product_collection') -
addAttributeToFilter('type_id', Mage_Downloadable_Model_Product_Type::TYPE_DOWNLOADABLE) -
getAllIds(); //Now create an array of attribute_code => values
$attributeData = array("my_attribute_code" =>"my_attribute_value");
//Set the store to affect. I used admin to change all default values
$storeId = 0;
//Now Update the attribute for the given products.
Mage::getSingleton('catalog/product_action') ->updateAttributes($ProductId, $attributeData, $storeId);
It was work for me.I hope it'll work for you
Amasty "Mass Product Actions" will allow you to edit product attributes in a variety of ways. This is what we use and it's going to be a life saver once we get the Configurable Products pricing tier working properly.

I checked some existing questions, but none of them explains how to create configurable products without child products data. I don't need to link products, I just need to create configurable product for later use.
So I tried that:
$_prod->setTypeId('configurable');
$_prod->setConfigurableAttributes('color');
But this is not working. When I click in admin on product, the product is created, but I need to choose first configurable attributes. So setConfigurableAttributes didn't make any action, but it also didn't invoke any error. What is the proper way for that?
I ended up with the below raw query:
$colorAttrId = 92;
$tableName = Mage::getSingleton('core/resource')->getTableName('catalog_product_super_attribute');
$write = Mage::getSingleton('core/resource')->getConnection('core_write');
$write->query("INSERT IGNORE INTO $tableName (`product_id`, `attribute_id`) VALUES ($prodId,$colorAttrId)");
So what i'm trying to achieve is that the product with the attribute 'promotion' set to 'yes' is displayed on the frontpage of the website. This is working, but the .phtml file i'am using with this is the regular list.phtml. This is currently showing all the items I have set to promotion but I only want to show 1.
So in short: How do I edit the list.phtml to only show 1 product instead of everything?
Change how you are pulling your collection. Clone/Rename your list.phtml, for example promotion.phtml. Then change this line, from this:
$_productCollection=$this->getLoadedProductCollection();
To this:
$_productCollection = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('*')
->addFieldToFilter('promotion', 1)
->addAttributeToSort('updated_at', 'DESC')
->clear()->setPageSize(1)->load();
And it should load only one item with promotion set to yes. Make sure you set the new template in either your CMS Page Content or XML, depending on which method this is added.
Explanation
Mage::getModel('catalog/product')->getCollection(): Gets the Product Collection. You can get other collections by changing the model, such as "catalog/category" and "cms/page".
->addAttributeToSelect('*'): Adds All Product Columns. This can be exchanged for things like ('name', 'url'). I'm assuming it's faster than loading all but I haven't benchmarked it. Since you're using the full template it's probably best to leave this set to all.
->addFieldToFilter('promotion', 1): Filters out products by attributes. Here we have the products filtered for all those with the 'promotion' attribute set to 1(yes/true). Products use this one, while categories use ->addAttributeToFilter() oddly enough. Definitely give Alan Storm's Collection Explanation(link below) a read through to know what all you can do with this one. You can add multiple filters to your collection, either by adding another ->addFieldToFilter(), or storing your filters in nested arrays.
->addAttributeToSort('updated_at', 'DESC'): Sorts the product collection by specific attribute and direction. Here I have the "updated_at" date set to descending order, "ASC" is ascending. You can add multiple sorting attributes, pay attention to the order you add them in, of course.
->clear()->setPageSize(1)->load(): These three are needed to make adjustments to how much the collection pulls. ->clear() must be called before it will allow changing how many products are pulled. The ->setPageSize() bit is where you specify how many products you would like to return, and ->load() of course loads the collection. Note that if you do not limit the size of the collection returned, you do not need this entire line, the products will iterate without having to call ->load().

I am trying to figure out how I might be able to do this - possibly in the mysql database, but I'm not sure of all the tables involved, so daren't go much further?
I have added an attribute called "condition" to the defaul attribute set.
I need to populate that attribute value for every product, but the admin system requires me to fill in many other attributes if I try to bulk update them using the admin form. This can't happen as "description" is different for every product, obviously.
So, can someone tell me how I might populate this attribute value with the value "new" for every product in my database?
Realistically, I can change this attribute value for the number of products that need a different value "used", but if the update could be filtered on SKU, I can make it work right first time. I think!
The programming approach is to save the following script in your Magento folder and execute it by visiting the address directly. It might be slow but that doesn't matter if it's only going to be run once and then deleted afterwards.
<?php
require 'app/Mage.php';
umask(0);
Mage::app();
$products = Mage::getResourceModel('catalog/product_collection');
foreach ($products as $product) {
// replace IS_NEW with a test perhaps using $product->getSku()
$product->setCondition(IS_NEW ? 'new' : 'used')
->save();
}
Not a programming answer so perhaps not suitable for Stack Overflow but there are a number of workarounds.
You could export all products to Excel, bulk update many rows at once then re-inport. Use Magmi if you have many products.
There are some extensions which let you update many attributes at once. This Mass Actions is expensive but gives you an idea what might be available if you search.
As much as I loathe desktop applications for web services there is Store Manager which specialises in bulk actions.
I understand how to programmatically create a product and also add to cart. I know this might sound dumb but is it is possible to generate a product on the fly and add that to the cart/quote but never actually save it in the database.
We want to create a made to order interface and I was thinking at the end it could add a bundle product with all the selections but that bundle product wouldn't actually exist in the backend.
I figured as long as you can make sure the quote and order has what it needs in terms of the product it would be ok, but obviously there is probably a lot that is tied to looking up stuff in the db on a specific sku or ID. I know that if you delete a product and then look at an order in the admin that causes issues, at least it did for this one scenario I was dealing with.
I was thinking of creating a giant bundle product that had like 6 different bundle items and each item could potentially have like 500 products and then based on what the user selects I programmatically add the bundle to cart. But then I wasn't sure if there would be a negative affect with having a gigantic bundle product like that as well.
UPDATE:
I don't think this will work, obviously there are a lot of information tied to the product in the database and we setup a test and right away we get an error for $item->getProduct(). We are moving forward with creating a giant bundle product and also the generic product with adding custom options on the fly, which Anda pointed out below. Any other suggestions will be greatly appreciated.
I'm not sure that clockworkgeek's approach is going to work. On every page load, Magento loads the items from the cart to make sure that they are still valid (in-stock, prices correct, etc), and amends the cart to reflect those values. My understanding of the system in the past has been that a product in the cart needs to have a corresponding database value to survive this process.
The "giant bundle product" approach is a pain, but in the past has been the best approach I have found. Attempting to change the values of the product (such as price or attributes) will be overridden by the cart checks, so you need a product w/ maximal flexibility, such as an overly-customized bundle product or configurable product.
Hope that helps!
Thanks,
Joe
Why not create a generic product in db and then set the product customization as custom options (additional_options) on the fly depending on the user selection. You can add custom options to the product (actually to the quote item) without having to save them in the database. I did this once for a website that sells glasses with prescription. The prescription was added as an option.
You can programmatically create Mage_Sales_Model_Quote_Items and add them to the cart. You've noticed it needs a product to match it's product ID but it needn't be a useful one. It could be a blank, disabled product, also created in code. All that's needed is a stub.
The necessary stuff for the cart is stored in the quote item - fields like name, value and quantity. Those fields are then copied directly to the order without using a product.
Mage::getModel('catalog/product')
creates a new product. you can add it to a cart, by doing something like this:
$cart = Mage::getSingleton('checkout/cart');
$product = Mage::getModel('catalog/product')
->setStoreId($storeid)
->setTypeId($type_id)
->setQty($quantyty)
->setWhatAttributYouWant($attribute);
$cart->addProduct($product);
product attributes you can find in the DB in tables that start like catalog_product_... or take an already created product, and see what attributes it has in the _data array (with debugger or just print_r($product->getData))
$attributeInfo = Mage::getResourceModel('eav/entity_attribute_collection')
->setCodeFilter('modellijn')
->addAttributeToFilter('brand', 114)
->getFirstItem();
Hi there. I would like to know the right syntax for the following:
Select the attribute modellijn where the attribute brand=114. The above syntax gives back an error. I have been searching for 2 days now for the right syntax but no result so far unfortunately.
I am hoping someone here is willing to help me!
So the first problem I see here is... that you are attempting to select the attribute for a particular brand. Attributes do not in fact have brands (nor modellijns).
Can you please clarify the use case? Are you trying to get the modellijn (that's fun to type) value of all products with brand 114? What is your expected output?
Or, if you're more comfortable as such, what would be the SQL query you'd expect to see generated?
Thanks,
Joseph Mastey
Okay, based on your update, I just wanted to clarify a few things.
Attribute sets have attributes
Attributes have options (sometimes)
Products have attribute values
Categories have products
If you just need to find the modellijin of a particular product, then you just need to ask for it. If you have a single product, this should do the trick:
$product = Mage::getModel("catalog/product")->load($id); // Magento does this for you in some cases
$product->getModellijn(); // this will return your value
$product->getAttributeText('modellijn'); // IIRC, this works for <select> type attributes
If you're loading products from a collection, you need to make sure to tell Magento that you want to load that attribute too. Selecting everything from EAV is even more expensive than selecting everything from a standard, normalized database. Therefore, Magento expects you to tell it what you need.
$collection = Mage::getModel("catalog/product")->getCollection();
$collection->addAttributeToFilter("brand", 114); // limit for brand
$collection->addAttributeToSelect("modellijn"); // * also works but is slow
foreach($collection as $product) {
$product->getModellijn(); // just as above
$product->getAttributeText('modellijn');
}
Let me know if that does it for you. If it doesn't, please amend your post above to include a more complete SQL statement, and if possible more information about where you are using this data. That will help me understand the context within which you're executing the code.
