I am facing a requirement to access values for an attribute that are specified in another scope on a multi-website/multi-store site. In particular, we need to display the Admin (default) label for an attribute in the frontend when the label for the Store has been set.
So the code should render the Hex value from the Admin column in one part of the page, and the textual Description from the English (US) on another part of the page. How do I do that?
Conversely, I have seen instances where values have been set on a Store View but are null for Default, and the code returns null even when the Store has been set. Can someone please explain how that works?
Here is how to do it using Magento classes:
// Get the model of the attribute in question
/* #var $attribute Mage_Catalog_Model_Resource_Eav_Attribute */
$attribute = Mage::getSingleton('eav/config')->getAttribute('catalog_product', 'color');
// Load the option collection for that attribute adding the storeFilter()
/* #var $collection Mage_Eav_Model_Resource_Entity_Attribute_Option_Collection */
$collection = Mage::getResourceModel('eav/entity_attribute_option_collection')
->setPositionOrder('asc')
->setAttributeFilter($attribute->getId())
->setStoreFilter();
// Load the product so we can get the correct option from the collection
$product = Mage::getModel('catalog/product')->load(39);
$productOption = $collection->getItemById($product->getColor());
printf("Default: %s, Store: %s\n", $productOption->getDefaultValue(), $productOption->getValue());
Adjust as needed.

I am building a Laravel Nova application and want to show a user with image and name.
/**
* The single value that should be used to represent the resource when being displayed.
*
* #var string
*/
public static $title = 'name';
As you can see above, the $title is used to represent the resource, but I want two values, a image (Avatar) and name (Sting).
Is this possible, or is it possible to show an other value like an image, instead of a string?
Use Avatar field
If a resource contains an Avatar field, that field will be displayed next to the resource's title when the resource is displayed in search results

how do I find the values of a product's attribute set?
For example, there's a product with an Attribute Set called shirts - T, with attributes of Gender, Shirt Size, and Color. Starting with a $_product object, how do I find the values of the attributes, e.g. Mens, Green, Large?
i am able to getting the attribute set value in the following way:
$product = Mage::getModel('catalog/product')->load($productId);
$prodAttributeSet = Mage::getModel('eav/entity_attribute_set')->load($product->getAttributeSetId())->getAttributeSetName();
I want to get all available attribute set values and codes for specific attribute set(i.e shirt - T)
$_product = Mage::getModel('catalog/product')->load($productId);
Now suppose you want to access value of manufacturer of this product, then consider following code.
$manufacturerValue = $_product->getAttributeText('manufacturer');
As you mention in comment for size and color here i can give you one sample code to use.
If it is a select or multiselect attribute, you still need to map the option ID's to option values. That is the case if you are getting a list of integers instead of human readable labels (e.g. for the color or manufacturer attribute).
// specify the select or multiselect attribute code
$attributeCode = 'color';
// build and filter the product collection
$products = Mage::getResourceModel('catalog/product_collection')
->addAttributeToFilter($attributeCode, array('notnull' => true))
->addAttributeToFilter($attributeCode, array('neq' => ''))
->addAttributeToSelect($attributeCode);
$usedAttributeValues = array_unique($products->getColumnValues($attributeCode));
// ---- this is the different part compared to the previous example ----
// fetch the attribute model
$attributeModel = Mage::getSingleton('eav/config')
->getAttribute('catalog_product', $attributeCode);
// map the option id's to option labels
$usedAttributeValues = $attributeModel->getSource()->getOptionText(
implode(',', $usedAttributeValues)
);
Direct DB query example
Depending on where you want to do this, here is an example of fetching the values without using a product collection. It is slightly more efficient.
Only use the following code in resource models, as thats where DB related code belongs.
This is meant as an educational example to show how to work with Magento's EAV tables.
// specify the attribute code
$attributeCode = 'color';
// get attribute model by attribute code, e.g. 'color'
$attributeModel = Mage::getSingleton('eav/config')
->getAttribute('catalog_product', $attributeCode);
// build select to fetch used attribute value id's
$select = Mage::getSingleton('core/resource')
->getConnection('default_read')->select()
->from($attributeModel->getBackend()->getTable(), 'value')
->where('attribute_id=?', $attributeModel->getId())
->distinct();
// read used values from the db
$usedAttributeValues = Mage::getSingleton('core/resource')
->getConnection('default_read')
->fetchCol($select);
// map used id's to the value labels using the source model
if ($attributeModel->usesSource())
{
$usedAttributeValues = $attributeModel->getSource()->getOptionText(
implode(',', $usedAttributeValues)
);
}
If you want all the attributes of an attribute set you can do the following.
$product = Mage::getModel('catalog/product')->load($productId);
$attributes = $eavConfig->getEntityAttributeCodes( Mage_Catalog_Model_Product::ENTITY, $product );
print_r(attributes);
I using Magento 1.6.2.
Is there any way to set the position for Attribute Option Labels on a Site View Level and not on a global level?
Reason: Here the Values for Color in English and German
Black / Schwarz
Clear / Transparent
Copper / Kupfer
Yellow / Gelb
It is obvious that the sorting is different for different languages.
Overriding the position value and sorting the values in the frontpage code is not possible because there are options where alphanumeric sorting doesn't make sense:
i.e. Small Medium Large
Please help
Yes, this is very possible. But it's a fairly deep change, depending on what you would like to accomplish with this. This will get you started:
You want to first add a new column to eav/attribute_option_value table. Here is the setup script for that:
$installer = $this;
$installer->startSetup();
$installer->run("
ALTER TABLE `{$this->getTable('eav/attribute_option_value')}` ADD COLUMN `sort_order` INT UNSIGNED NULL DEFAULT 0;
");
$installer->endSetup();
Next, you need to rewrite Mage_Eav_Model_Mysql4_Entity_Attribute_Option_Collection. When performing the join for the store filter, you need to add your sort_order there:
public function setStoreFilter($storeId=null, $useDefaultValue=true)
{
if (is_null($storeId)) {
$storeId = Mage::app()->getStore()->getId();
}
$sortBy = 'store_default_value';
if ($useDefaultValue) {
$this->getSelect()
->join(array('store_default_value'=>$this->_optionValueTable),
'store_default_value.option_id=main_table.option_id',
array('default_value'=>'value'))
->joinLeft(array('store_value'=>$this->_optionValueTable),
'store_value.option_id=main_table.option_id AND '.$this->getConnection()->quoteInto('store_value.store_id=?', $storeId),
array('store_value'=>'value',
'value' => new Zend_Db_Expr('IF(store_value.value_id>0, store_value.value,store_default_value.value)',
'sort_order'))) // ADDED
->where($this->getConnection()->quoteInto('store_default_value.store_id=?', 0));
}
else {
$sortBy = 'store_value';
$this->getSelect()
->joinLeft(array('store_value'=>$this->_optionValueTable),
'store_value.option_id=main_table.option_id AND '.$this->getConnection()->quoteInto('store_value.store_id=?', $storeId),
'value',
'sort_order') // ADDED
->where($this->getConnection()->quoteInto('store_value.store_id=?', $storeId));
}
$this->setOrder("store_value.sort_order", 'ASC'); // CHANGED
return $this;
}
To show what is going on: each attribute has a source model. The source model is responsible for providing the values in a frontend dropdown-type list (select, multiselect). If the source model is Mage_Eav_Model_Entity_Attribute_Source_Table, which it will be by default if the attribute type is select or multiselect, then this code retrieves the values:
$collection = Mage::getResourceModel('eav/entity_attribute_option_collection')
->setPositionOrder('asc')
->setAttributeFilter($this->getAttribute()->getId())
->setStoreFilter($this->getAttribute()->getStoreId())
->load();
As you can see, we are rewriting the setStoreFilter() function. This is the last one called. You might want to add an unshiftOrder('main_table.sort_order', 'ASC') at the beginning of the rewritten function, just for good measure that the `main_table.sort_order does not get in the way.
I'll leave it to you to make the necessary adjustments to the admin panel to provide the option for setting the sort order matrix.
I want to make a new select attribute option visible in all products.
I have products that each use a select box attribute called "bracket_size". That attribute has three options:
(/admin/catalog_product_attribute/edit/)
Most of the products only have two of these options selected:
(/admin/catalog_product/edit/)
If I select "18mm" in that screen then it shows on the frontend.
I want to create an upgrade script that will set all products to show the "18mm" option.
I had been doing it by selecting all products, fetching them and updating their attribute value:
$options = Mage::getSingleton('eav/config')->getAttribute('catalog_product', 'bracket_size')->getSource()->getAllOptions(false);
$option18mmId = $options[0]['value'];
foreach (Mage::getModel('catalog/product')->getCollection() as $product) {
// Get a writable product
$product = Mage::getModel('catalog/product')->load($product->getId());
// All products in these attribute sets should have bracket sizes
$bracketSizeValue = $product->getBracketSize(); // string containing option IDs - something like '645,345'
if (isset($bracketSizeValue)) {
// Get options currently selected for this product
$optionIds = explode(',', $bracketSizeValue);
// Check if the option is already included in this product
if (!in_array($option18mmId, $optionIds)) {
// If not, rebuild the attribute value to add it
array_unshift($optionIds, $option18mmId);
// Add it back to the product
$product->setData('bracket_size', implode(',', $optionIds));
$product->save();
}
}
}
But this doesn't work. It throws an error:
Warning: Invalid argument supplied for foreach() in /.../public/app/code/core/Mage/Eav/Model/Entity/Abstract.php on line 1068
at the $product->save() line.
How can I do this?
If you trying to save products in setup/update script then you need to disable update mode and set current store id first:
$app = Mage::app();
$app->setUpdateMode(false);
$app->setCurrentStore($app::ADMIN_STORE_ID);
Ideally it would be done exactly before saving and then reverted back after saving:
$app->setCurrentStore(null);
$app->setUpdateMode(true);
Then you could also optimise your code my removing loading and saving of each product and doing it on collection items instead.
Loading of collection with desired attribute:
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('bracket_code');
Saving of changes on collection items:
$collection->save();
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.

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,
Jordan!
