$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.

I'm able to fetch information for whatever table I need the problem here is the update, insert, and delete records, is not working..
I have read the Joomla doc's but even doing the simplest update queries are not working... so here is my code:
UPDATE:
// I'm getting the data from an array
if (!empty($_POST['data'])) {
$getData = json_decode($_POST['data'], true);
}
// after this line I have a foreach for the array
// in the foreach I have a few IF's
// ether if the result from IF is True or False
// in both I have similar queries
// So let say IF return true;
// Lets prepare the Data using OBJECT's
$object = new stdClass();
$object->product_id = $v['product_id'];
$object->product_name = $v['product_name'];
$object->product_price = $v['product_price'];
$object->product_number = $v['product_number'];
$result = JFactory::getDbo()->updateObject('#__tienda_product', $object, 'product_number');
// that should Update my tables but it doesn't ... now my table has about 21 columns
// but I only need to update 4 columns base on the column product_number
You might have notice the $v['product_id'] where $v is from the foreach, the foreach and the first query are working fine, I did a few echo's before moving to the Update part just to make sure I'm getting the correct data in a format that it should be... any way... the Update part is not working... so I thought it may be because of my table I when to use one table from the regular instalation of joomla... but it still the same no result on the update...
Does any one know how to "update" a table using Joomla CMS as framework?...
Remember I want to use the updateObject() method...
Why don't I use Joomla Framework instead of the CMS's library?
Well, I can give you a few examples, let say:
a business man want a simple basic report, he doesn't care about managing the site he has people to do that, he also gets a sales report, but he doesn't trust the crew just yet and he want to able to see and compare the result, and he needs and standalone without all the fancy tools that joomla has and for that he need an standalone app that can give that kind of report... ok I might have gone a bit far, but the idea is to have basic, simple, easy to read reports and updates, and that is why I have started this project.
Again, I already went to joomla and read the docs but following their examples it just not working... now, am I have to declear all of the columns even if they don't need to be update? or am I missing an execution for the query which in joomla doesn't mention any executions when using $object() only when using regular queries SQL... the idea is to use $object() ...
Thank you for taking the time.
You have defined the updateobject as a variable, and are not calling it. try changing this:
$result = JFactory::getDbo()->updateObject('#__tienda_product', $object, 'product_number');
to this:
JFactory::getDbo()->updateObject('#__tienda_product', $object, 'product_number');
Also, on a side note, you should not use $_POST and instead should use JInput
How can I set the value of a given attribute to the same value for all products (efficiently)?
By efficient I mean in one transaction, not having to loop through the entire product collection.
In the past I've used Mage_Catalog_Model_Product_Action for bulk updates on products, and it runs pretty fast
Mage::getSingleton('catalog/product_action')
->updateAttributes($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 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'm trying to add some custom options to already existing products in Magento. Seems to work fine, I added the needed rows in the following tables:
catalog_product_option
catalog_product_option_title
catalog_product_option_type_value
catalog_product_option_type_price
catalog_product_option_type_title
I also updated has_options and required_options for the right product, in the following tables:
catalog_product_entity
catalog_product_flat_1
catalog_product_flat_2
catalog_product_flat_3
When I open the product, the options doesn't show, actually, it shows less. The button to order it disappears. When I open the edit page, it does show the options. After saving, it appears on the front-end too.
What am I missing?
Update:
After manually going through literally every query that was executed after a save action, I discovered what I was missing. When a product has options, it has to display them in a different template (or whatever it's called in Magento). To do this, you'll have to change the value for the attribute options_container.
So, there's a really easy fix for that. Just look up the attribute_id in the table eav_attribute. Then just run the following query for each product:
UPDATE `catalog_product_entity_varchar` SET `value` = 'container1' WHERE `attribute_id` = 836 AND `entity_id` = $productId;
That'll do the trick! :)

You really shouldn't be accessing the database directly for any reason. This undermines the power and resourcefulness of using an EAV system.
Extend Mage.php if outside of magento (disregard if not)
Make a collection of whatever entities you want to manipulate
Use said collection to write/read data

I need some guidance. Forgive me for a lengthy post but I need to explain myself. In my world, there is no one who understands what I am talking about so I have to go online for assistance.
I am an architect doing my own website because work has dried up and I plan to use an improved website for a marketing campaign.
I have done what I'd call a "lash-up" of this site which functions OK. But it's nowhere near ready to publish. I am trying to get it reorganised to do this and am moving the whole thing over to Codeigniter. My puzzle relates to views in Codeigniter.
One of the main pages for potential clients is the projects page showing work done. It uses nested tabbing. As I have said, I've made it work OK in ordinary procedural PHP.
Note that the projects are organised by category i.e housing, commercial etc In each category there are projects.
Actually the tabs are dynamically produced with some assistance from jQuery. I mean by this that my homespun php creates markup based on what's returned from the database.
The tab markup is the usual one of an unordered list whose li elements contain anchors whose hrefs reference divs arranged below. To achieve nesting, these divs then contain another ul with a further set of divs related to it.
The top tabs correspond to a category e.g housing, commercial. The lower tabs correspond to projects within a category.
I've made this work with four queries before. I think at least one may be redundant but I said it was a "lash-up".
Query 1: "select distinct pcat, pcatid from pcategory inner join projects on pcatid = projcat order by pcat desc"
From this query I get hold of the id used in the href.
Query 2 : same as above but this time the id is used for div id.
The next query is the source of my puzzlement because I don't see how to replicate it with CI.
Query3 :
$jobcat=$row2['pcatid'];
$queryall3 = "select projid, projtit, projcost, projdate from projects where projcat= '$jobcat'";
This query uses the category id - $jobcat - returned by each iteration of the while clause used to expand the results from query 2. In other words, it runs inside the query 2 while loop so it can get the category id and then get all the projects related to it.
The results of query 3 are used to form the lower tabs, and their href value is the id of the project.
Query4: same as query 3 and used to populate the lower divs with data from the database relating to a specific project.
So, finally my question: it seems to me that query 3 is difficult to manage using the Codeigniter set up. I can imagine an array of results looped over in a view. What I can't conceive is how to make a model call within that loop.
Apologies for a long-winded question and any maladroit coding assumptions exhibited. Assistance would be a blessing.

I don't really see what you're asking, but it seems that you want to know how to perform queries in CI?
In which case I suggest you take a good read of the docs
$this->db->select('pcat, pcatid');
$this->db->distinct();
$this->db->from('pcategory');
$this->db->join('projects', 'pcategory.pcatid = projects.pid', 'inner');
$this->db->order_by('pcat', 'DESC');
$result = $this->db->get();
I very much doubt this will work as I do not know your table structure but may give you an idea of how to use the active record class in CI.
You can of course just use the query method:
$results = $this->db->query('YOUR QUERY HERE');
the active record class can do a lot of the work for you, however.
As for about being difficult to do in CI, this is simply untrue - you just need a clearer picture and understanding of what you want to achieve.
Edit
$jobcat=$row2['pcatid'];
$queryall3 = "select projid, projtit, projcost, projdate from projects where projcat= '$jobcat'";
$results=$this->db->query($queryall3);
$data = $results->result_array(); // get the results of the 3rd query as an array
// new query
$this->db->select('query_4_select'); // select whatever you need
$this->db->from('whatever_table');
// this probably isn't the most efficient way, but for examples sake:
foreach($data as $row) // using the result_array from above
{
$this->db->or_where('query_4_id', $row['id']); // the magic !!
}
$new_results = $this->db->get();
So essentially, you get the ID's from query 3, run it through a foreach and build a where x=x or x=y or x=b type query, which will then (hopefully) return the desired results.
This is one way, you will need to tweak it.
But it sounds like you can just use a join? Perhaps if you could post your entire tables structure.
