first of all, sorry for my english, but I'll try to explain myself best I can.
My question is little tricky, because I made some important changes in the core code of VirtueMart.
For some reasons, I added an attribute to the Custom Fields, like Price, called Availability.
TIP: The admin site is in Spanish. Disponibilidad = Availability
So, now, when I try to change any value of any created Custom Field, I can't save it. I mean, I can change the value, but when I apply them, It doesn't be saved.
The only field that I can change, is the field I created, the Availability (ironically).
So, my principal question is, how does VirtueMart to pick up the data from the table and sends them to the database?
I work with
Joomla v.2.5.11
VirtueMart 2
Thanks
The workflow is like follows,
When you save the products details on the backend , It calls a function store() on the product.php model. under administrator/components/com_virtuemart/models/. Inside this function an area like follows.
if(!class_exists('VirtueMartModelCustom')) require(JPATH_VM_ADMINISTRATOR.DS.'models'.DS.'custom.php');
VirtueMartModelCustom::saveModelCustomfields('product',$data,$product_data->virtuemart_product_id);
It loading the custom model file from the same path and do the task inside saveModelCustomfields()
Hope it helps..

Background
Let us consider a hypothetical scenario. Suppose we have five different tables in our database,
Customers
Categories
Products
Orders
OderDetails
Our client wants us to add a search bar to the frontend, where a user can search for a specific product and upon tapping the search button, matching products has to be displayed on the frontend.
My Approach for Tackling This Problem
In order to add the aforementioned functionality, I came across the following strategy.
👉 I would add an input box to ender the product name and a submit button.
👉 Upon pressing the submit button, a GET request will be sent to the backend. On the query parameters, the product name that has been entered by the user will be included
👉 Once the GET request is received to the backend, I will pass it down to the ProductsController and from within a method defined inside the ProductController, I will use the Product model to query the products table to see if there are any matching results.
👉 If there are any matching results, I will send them to the frontend inside a JSON object and if there aren't any matching results, I will set a success flag to false inside the JSON object and send it to the frontend
👉 In the frontend, if there are any matching results, I will display them on the screen. Else, I will display "No Results Found!"
Problem with My Approach
Everything works fine if we only want to search the products table. But what if, later our client tells us something like "Remember that search functionality you added for the products? I thought that functionality should be added to orders as well. I think as the list of orders by a user grows and grows, they should be able to search for their previous orders too."
👉 Now, since in our previous approach to search products was implemented in the ProductController using the Product model, when we are adding the same functionality to Orders, WE WOULD HAVE TO DO THE SAME THINGS WE DID IN THE ProductsController AGAIN INSIDE THE OrdersController USING THE Order model. It does not take seconds to understand that this leads to duplication of code.
Problem Summary
❓ How do we add an API endpoint in laravel for a search functionality that can be used to search any table in our database and get results, instead of the search functionality being scoped to a specific controller and a corresponding model?
A good start would be to create a trait called something like searchable and add it to all the models you want to search and put any shared logic between the different models in there. Possibly you'd want to manually allow different columns so in each model you have an array of searchable columns which you'd refer to in your trait.
Your controller would have to point to the related model and call a method in the trait that searches.
As others have pointed out this is a high level question so I won't go too much in detail. Of course there are a million ways to implement this, just try and keep shared logic in place.
I'm trying to modify the credit card form to add some new custom fields named "Bank Name" and "Bank Phone Number" and it seems this cannot be done through the back-end.
I've searched the web and on here but I haven't been able to find anything in reference on how to add a new custom field to the credit card form. I would think it's almost the same as adding a new field to the customer registration form but I have no clue what to do database wise.
If anyone has anything I can use to work on this, I'd greatly appreciate it.
You should start by informing which version of Magento you are using and which methods you have already tried.
Without knowing that it is hard to help you, but you might want to try this possible solution, this one, or even one of these modules: Checkout Fields Manager or ADDITIONAL CHECKOUT ATTRIBUTES. If none of the above work, try this search.
No, Magento admin panel will not add custom columns for you. You need to do it yourself.
First, you need to edit the .phtml file to include these two fields to show up in frontend.
Second, you need to add two new columns (with same name as your fields, explained later) in relevant DB table (i guess sales_flat_order_payment). But that will affect for all payment methods, so define it something like VARCHAR(255) NULL.
Third, when Magento saves the CC info, you need to check if it is saving whole data array, then your field's name posted will match your table field and get inserted automatically. Else you need to edit it.
Also, next time please post some code, atleast something you have tried.
I'm a beginner using Joomla 1.5. I have a page which shows articles in a blog format. My objective is to show/filter the articles per year (which isn't that many) based on user input. I'm planning to create a module on the right side, showing a dropdown box of the years, and retrieve the results by passing the year parameter as part of the URL
Ex.
http://sample.com/index.php?option=com_content&view=category&layout=blog&id=39&Itemid=24&year=2011
What is the best, simplest way of passing and processing additional parameters to com_content via URL? Can I do so using extensions such as K2 and flexicontent? If not, can someone advise me what code to add and where, in com_content? If I have to extend com_content itself, can someone guide me how to or point some useful articles?
Appreciate the help. Thanks
I don't know if K2 or flexicontent offer this option, but com_content appears NOT to have this feature.
I would just build a module, create a query and use the table jos_content, select only the fields that you need (like title) and check the field created to be in the year you need.
I've never set a store up to use Price Alerts before, and now that I've gone through and gotten it to work, it appears as though the alert is only triggered when a product's 'Price' attribute changes.
This is nice, but what about tiered pricing? Looking through the ProductAlert core module, I am not sure where this attribute is being filtered.
I'm guessing that an additional model, say 'productalert/tierprice' will need to be created, followed by a new method in Observer.php, likely _processTierprice(). Just not sure if this concept is correct... could use a little guidance.
Thanks!
This shouldn't be too difficult; lots of options (it's Magento, after all)!
I'd add new methods to deal with tier price alerts. For products with tier pricing, you'd need to capture the relevant tier data along with the final price (either in a new table or in new columns on the existing product alert table). The alerts are sent out via scheduled job. So, in a nutshell (overrides where necessary):
Alter the product alert schema as necessary, and amend the frontend form fields to suit
In the overridden Mage_ProductAlert_AddController add a tierPriceAction() method to process the alert subscription, or adjust its existing priceAction() to handle the data being posted in / tier condition
Override Mage_ProductAlert_Model_Observer as needed; I'd include a _processesTierPrice method() similar to _processPrice().
Add a resource model method to get the tier-related prices
Add a tier price email block and template (reference Mage_ProductAlert_Block_Email_Abstract)
Profit!
As a reference for your price logic, see Mage_Catalog_Model_Product_Type_Price.
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))
