I have a situation:
I have products that are in a CodeIgniter Cart custom store.
Each product has an ID associated with it, but also has options for it (sizes).
These sizes all have different prices. (We're talking about photos being sold at different print sizes).
Because CI Cart updates, adds and deletes based on the product ID inserted, I am not able to insert one product with 2 different sizes.
As of now, the only solution I can think of is to pass the ID to the cart as IMAGEID_OPTIONID so that it contains both IDs.
However, I thought there might be an easier, more uniform way of doing this?
Or a better solution than an ID that isn't (on it's own) associated with anything specific unless i explode it..?
I recently built a site that had these constraints. In short, you'll want to create a distinction between "products" and "product groups". Think of it as managing the most discrete data units. In reality, shirt X sized medium is actually a different thing than shirt X sized large...doubly so if you have prices that are built on these qualities (this becomes more realistic when you consider cloth patterns or colors).
So anyway, if you have a "groups" table, a "product_groups" table, and a "products" table, you can keep all of these ideas distinct. On your products table, you can have columns for "size" and "color" (and any other distinguishing property you can think of) and a column for "price". Alternatively, you can go even more hardcore and make separate pricing tables that match up prices to unique products (this would be especially useful if you want to keep track of historical prices and discounts).
Then in your cart you can simply attach product_ids to cart_ids and perform a couple of joins to determine what "group" this product is a part of, what pictures are in that group (or exist for that product), and so on. It's not a simple problem, but following this line of thought should help get you on the right path.
One last point: keeping track of unique products like this also makes inventory accounting much, much more straightforward.

I'm working on a e-commerce search page and need to free text search products and have multiple facet options and sorting capabilities. The issue I'm facing has to do with product prices:
One product has multiple prices - there are special discounts, B2B customer specific prices, and specific B2C prices. There could be a few hundred prices per product.
I need to be able to do to a full text search on products, but still be able to sort on one of the selected price groups.
My initial though would be to put all of the prices into the product item, but that means I'll need to update the product objects in the index every time a price changes - which is often. This will also make the objects quite big.
I see that elasticsearch now has the capability of HasParent/HasChildren queries, but I am not sure if that is the right way to go, or if it even is possible.
Is it possible to keep prices as a separate type outside the product type and use the HasParent/HasChilden queries to sort the procuts on the price?

I would personally be inclined not to store complex pricing data within Elasticsearch, at least not prices calculated by business logic such as discounts and specific B2C prices.
A base price could be stored for querying and sorting, and apply pricing logic to this with scripting, using script queries and script sorting, respectively.

Parent/Child relationships operate on documents within a single index, with a join datatype field on a document to indicate the relationship between a parent and a child, and child documents indexed on the same shard as the parent. If children are not evenly distributed across parents/shards e.g. one parent document has a million children and the others have only a few each, it's possible to end up with hot spots within shards that can affect performance. Product and pricing data doesn't feel like a good fit for Parent/Child; pricing sounds like it's too dynamic to be stored within documents.
We are about to begin working on an addition to Magento 1.14.2 EE that will allow us to merchandise and sort products within categories at a store level. currently we do this by having 3 entirely separate root category trees, our editors are finding this cumbersome, and our indexing takes 3x the time it should take to reindex a single tree.
The plan is to add a store_id column to the catalog_category_product table which currently stores the product_id, category_id and products position within the category in question.
So my questions are fairly general at this point, has anyone attempted this previously and are there any obvious pitfalls that we are likely to encounter as a result of attempting this? The solution to us seems fairly obvious yet it hasn't been implemented yet by Magento, surely this is a piece of functionality that would be useful for any company that has a presence in multiple countries.
I have an e-commerce site that provides made-to-order clothing. I've created a configurable product and just one associated product.
Is it possible to display all of the possible attribute combinations within just one associated product rather than manually add every combination?
I've tried allowing out of stock products to be displayed, but this didn't show all of the possible combinations.
I'm not hugely experienced with Magento, but I've used many CMS systems and inventory management products. I've never once seen a matrix / configurable / multi-variation / whatever you want to call it setup where you didn't have to create each combination as a distinct SKU. I'm not saying it's 100% impossible, but I'd view it as extremely unlikely and probably a waste of time to pursue.
Why not just create your configurable products and their sub SKUs via CSV import? It will be far easier and faster than creating them one at a time. Creating every combination will also be extremely easy. If you're not comfortable with Excel, you need to correct that yesterday if you want to be good at product management.

I've started working on a new Magento webshop which has roughly 250000 different products. Each product can have different conditions (new, used, damaged, etc., each with their own price.). Magento doesn't seem to have a method to implement this at the moment. Of those 250000 products, there are about 150000 different conditions in stock and another 150000 conditions which aren't in stock but do have a price (which can be put on the wishlist).
Some numbers: 1500 categories, drop down attributes (country) with > 300 options, integer attributes (year). Starting with two websites 6 languages each.
I've thought out two solutions to solve this problem:
Grouped / Simple product structure
We create a grouped product which is the container product, each condition will be a different simple product. We'll relate these products to the grouped product.
The nice thing about this solution is that is pretty easy to implement, we'll have to import the data in the correct way and all the information is exactly presented in the way we want.
New Product type
We create a new product type which can have multiple conditions, each with their own inventory. On checkout the inventory is substracted. The problem with this is that implementing the CatalogInventory model in this way probably is difficult and building a whole product type is time consuming and bugprone in general.
The advantage of this solution is this that there will be about 2-2.5x times less products in the system.
Others
Are there any other options to solve this? Maybe there is a module that does all this?
In conclusion: Of course I prefer the first solution but can Magento handle that? Does anyone have experience with this much Grouped Products? The system will have about 550000 products (grouped + simple) products in the system, what will be the performance implications of this? What happens when the site grows and we'll have twice the amount of products?
Without knowing more details I'd lean towards using a new product type or just adding the feature independently of product types if you have a use for configurable products (I definitely wouldn't try to duplicate the configurable product type). I'd disable inventory management and use some additional tables which hold individual item inventory with the per-item conditions and maintain a separate inventory that way. Use events and overrides to control the CatalogInventory stock status as needed. Creating new products constantly which are largely duplicates seems like a hassle worth avoiding if this is a long-term endeavor that needs to scale.
However, the Grouped/Simple method might be a viable short-term solution and appropriate if the project is in it's early stages and can't afford a huge initial expenditure. If well-planned, a script should be able to convert all of the old grouped/simple products into your new product type when ready to launch.
I have a customer who retails third party batteries, and some batteries can replace several OEM models.
For instance, 3rd party SKU 12345 may replace Toshiba N23 and HP 53214, thus my customer would like to create two products with the same SKU in front end (they are essentially the same product). However, Magento by default does not allow duplicated SKU.
My current solution is to set SKU to not required from the backend, and add another attribute called Model that allows duplicated values, and display the Model in front end.
Is there a better way to do this? Or is it possible to allow duplicated SKU?

It sounds to me like you've found a good solution. I'm not so sure you should try to have duplicate values for SKU for two reasons.
First the whole point of SKU is that it is a unique identifier. That's its only reason for existing. If you're going to have duplicate values, then it's not a unique identifier; it's just another attribute. But of course Magento still needs a unique identifier to work, which means that this is an extra field, which takes us exactly where you are now.
That said we come to my second point which is this... I'm not exactly a Magento guru, but I've built my share of e-commerce sites and one thing I've learned is that they depend on certain unbreakable rules to work properly. One of them is that unique identifiers are unique, both on the database and application level. As such, a large part of the website depends on this to function correctly. Which I'm pretty sure goes for Magento too.
So trying to change such a basic premise in something so complicated will only lead to horrors and a slow descent into madness.
This sounds like a good solution that I extended a bit further, however what I did with multiple store was to create a visible attribute ITEM_SKU (Item SKU) - make it visible and searchable and then concatenate the store_id to Magneto SKU to make it unique.
So SKU becomes (Store_id "-" SKU).
It surprises me how often people are willing to break who-knows-what parts of Magento, just to get a specific piece working how they expect.
The proper way to allow for duplicate skus is NOT to (unless you'd like to re-write large parts of the framework). You CAN, however, add a custom attribute to products that shares all the same settings as "sku" minus the setting that requires values to be unique.
Changing product pages, emails, etc to show this value instead will require a little extra work but will save you headaches later.
Why don't you create 1 product (SKU 12345) and list this product in multiple categories. So your multiple categories will be Toshiba and HP. The same product (SKU 12345) will be listed in Toshiba and HP.
