I don't know if it's possible, but I had started to try by following the documentation that explains how to use the overrides. I've made some progress (creating the filter with this new type in the backend seems ok) and I have created these files : \administrator\templates\atum\html\com_hikashop\administrator\classes\filter.override.php \administrator\templates\atum\html\com_hikashop\administrator\types\filter.override.php My question is about the override in the 'classes' folder: I have tried these classes without result: class hikashopFilterClassOverride extends hikashopClass { class hikashopFilterClassOverride extends hikashopFilterClass { 1) I understand that the 'displayFilter()' function is used, but is it possible to override it? Because whatever I do, I pass in the function defined here: (~l.382) \administrator\components\com_hikashop\classes\filter.php Other question: In this file, we have the code (~l.384): 2) Is there a way to call a class defined in the '\classes\filter.override.php' file ?

The URLs are simply completely wrong, which is mainly due to the Itemid being hardcoded to the URL. When I look at the router, I also see issues there and it would start with unnecessarily complex code there. The question would be, which Joomla versions you are supporting, because unless you are support Joomla from before 3.6, you could drop half the code in your router. To be specific: could be replaced with Where ... is the actual program code. That code would be working from Joomla 3.6 onwards. Besides that, it would be nice if the router would discover the Itemid dynamically similar to how the core does it. That means that you don't have to store the Itemid in the finder and if you change your sites structure, move a category to a different place or something similar, your URLs would still be correct.

I have made a plugin that adds customer-specific information to the pdf of an E-book, and then makes it available for download. I am using onBeforeDownloadFile. It works perfect for 1 pdf....but I have hit a small problem if the customer orders multiple downloadable products. When hikashop executes onBeforeDownloadFile(&$filename, &$do, &$file, $options) how can I obtain the information which download button was clicked? Suppose that the customer has purchased 10 downloadable products, and is now in the download page. There are 10 buttons to click on for download. Click on button 1, and my plugin adjusts all 10 pdf files.....but unfortunately always shows the first one. I can get the order ID from: $order_id = $file->order_id; I can get the entire order and user information from: $app = JFactory::getApplication(); $orderClass = hikashop_get('class.order'); $FullOrder = $orderClass->loadFullOrder($order_id, true, false); From that I can get for example the invoice number: $InvNum = $FullOrder->order_invoice_number; But how do I know which title (product ID) the customer wants to download? Something like this will only iterate through all products. foreach($FullOrder->products as $product) { $ProductID = $product->order_product_code; //adjust filename } I need to know which download product the customer just clicked on. So that I only have to adjust that specific pdf, and only show that specific pdf. I guess the answer must be somewhere in your downloads.php.

I managed to write a Hikashop plugin that adds user-specific information in the header of each page of the pdf (social DRM) of an e-book. It all works nice..thanks to your help in other posts. The last problem is delivery to the customer. The source file is called book1.pdf (for example) and is in a safe place. After the user-specific information has been added, it is called book1InvoiceNumber.pdf....where InvoiceNumber is derived from $order. I have 10 of these books; some are 5 Mb....some are 100 Mb....so emailing them as an attachment is not an option. The easiest option to get the adjusted pdf to the customer is to automatically save it in the 'safe' directory, and email the link to the customer. And once in a while clean it up manually. That falls within my technical abilities. By 'safe' I mean out of sight of people who are trying to guess the path to a directory. The fanciest option would be to use the download options from Hikashop. That is...add the source pdf to the Product -Images and Files, and once the order is confirmed, let Hikashop email the customer with the download link and also the options to limit the number of downloads and the download time. Problem: Currently, Hikashop does not know that the pdf link has changed to a user-specific pdf file. Is it possible to change the link to the pdf file in the user confirmation email, and also on the user-download section? Or formulated differently....is it difficult to do this?

In the onBeforeCalculateProductPriceForQuantity() event handler of a system plugin, I try to construct a product object, including all related information. I need such an object, including any associated custom fields and other data, to do some non standard price calculations. The way I try to obtain that product object is as follows: * Get a reference to the product class: $productClass = hikashop_get('class.product') * Load the product using the product_id in the method parameter: $productClass->getProducts([$product->product_id]) * Load additional product data using the now available product(s) in $productClass: $productClass->loadProductsListingData([$productClass->products[(string) $product->product_id]], ) * Load product options in a similar fashion: $productClass->loadProductOptions(([$productClass->products[(string) $product->product_id]]) I feel very uncomfortable with the way I managed to get what I need, but in the old, complicated and confusing, non-modular codebase that is HikaShop is, I saw no other way. It gave me the product object I need though and everything seems to work just fine, up to the point that I go to the checkout page and change the ordered amount of a product. This also triggers my onBeforeCalculateProductPriceForQuantity() method, which should be fine, but apparently isn't. This is what I see happening: * When changing the product quantity, an AJAX call is made which eventually calls hikashopCartClass::loadFieldsForProducts(), which in turn calls hikashopFieldClass::getData(). * That getData() method fills a static variable with product data. Items in that data collection contain an attribute field_categories, which contains a comma separated string of category id's. * Somewhat later, my onBeforeCalculateProductPriceForQuantity() event handler is called. * The call I make to hikashopProductClass::loadProductsListingData() (see 2. above) in turn calls hikashopProductClass::loadCustomItemFieldsForProductsListing(). That last function call is where the problem starts. For some reason, it turns the comma separated string of category id's mentioned above into an array. Then, when hikashopCartClass::loadFieldsForProducts() is called a second time around as part of the same AJAX call, an error occurs because an attempt is made to trim() an array, which obviously is not allowed. This results in the following message in the shopping cart area: trim(): Argument #1 ($string) must be of type string, array given. What must I do to resolve this?")

Refactor all your classes, starting with a well designed Product class, which should be and do more than be a Product :) Turn factory methods, that currently manipulate static objects or objects passed by reference, into methods that return properly typed objects. For instance, turn hikashopFieldClass::getData() into something like ProductFactory::createProduct(), which returns an object of type (class) Product. Keep things simple.

To simplify the User Registration Forms, I am using Layout Template overrides. We are using a large set of User custom fields as a User Profile which are only needed for a small set of Joomla Users, but are rarely needed for Store Customers - we can't make them "required" so we modified the Registration templates. All of that is working fine, both through registrations via purchases and the online registration form (HikaShop's form, not Joomla's). If a registered Joomla User accidentally visits the Registration page, I want to redirect them to the custom "Welcome" article we built. Using Joomla's access control on the Menu item gives us the benefit of hiding our menu's "Create Account" link from registered visitors, but it redirects a User back to the Home page, along with an error message we'd rather customize. I don't think there's a way to customize that built-in redirect, so I'd rather handle redirection on the Registration page itself. This sounds simple: just add an application->redirect() after checking the User's Guest property. The problem is that for some unknown reason, my test-driven redirect's address value gets overridden by one which sends the browser to HikaShop's Customer Dashboard page - which we don't even run an instance of. (the redirected url becomes "/component/hikashop/user/cpanel") I have no idea where to even look for this problem. Suggestions? Thanks.")

However, a new employee to whom this applies wasn't informed, so we learned that since the site now uses the AJAX add to cart process, the error message - which uses Joomla's "enqueueMessage" methods - no longer displays to the user until they move to some different page or physically reload. The plugin still works the way it was written, and I see that I need to change onBeforeCartUpdate() to onBeforeCartSave(), but being AJAX, is there a way to deliver an error message to a user who fails to qualify for this AddToCart process? Also, the AJAX interaction makes it very difficult to review the structure of the $element object argument. Is there full documentation of the $element object?")
