linkOverview

linkFeatures

linkGeneral information

The add-on is designed for automatic creation of Related products selections for Reference product on the bases of the technical features of its values for Reference and Related products (it provides the intellectual approach as values of the product features are analyzed during selection. It makes the selections maximally logical and comfortable for clients).

  • allows creating the links on the bases of reference to Category - Category (you can select the Related products from Category B for Reference products from Category A or you can select the Related products for Category A in the mode of selection of analogical Reference products)

  • in the frame of link the add-on allows creating the rules of selection which can work in two modes:
    1) Without features ‒ for all products from Reference category will be selected the products from Related categories without any features.
    2) With features ‒ the system will show the Reference products on the bases of mentioned features and its values, and select Related products with the appropriate features and its values.

For With features mode when selecting Related products, it is available a special variant of feature value Variant of Reference product for Equally operator. In this case the system will select Related products according to the features values of the Reference product (Related products will have the same features values as the Reference one).

  • allows to take into account price, products in stock, manage quantity in a selection and products sorting.

  • adds a block (with individual settings) for the product page to display selected products that are separated with tabs according to its relations (block view is provided additionally for UniTheme2 and YoupiTheme to more conversion places without layouts). Besides, the tab name will be the name of the appropriate relation.

  • allows to display recommendations of the products based on the selection results in a pop-up window of approval to add the Reference product into the cart, as well as for the cart page where the Reference product was added.

  • uses a powerful system of background, actualization and caching of the selections (all selections are held in the background mode, recorded into the data base and are actualized in periodicity period with CRON). Add-on doesn’t create any load when the accessories are displayed even when several millions of products are shown.

linkRelation and Rule creation (Basic information)

Before the Relation and Rule creation, you should think about products category and features that you want to display accessories for. For example:

  • Relation Tablets SAMSUNG. When opening the laptop with the manufacturer feature Samsung from the Electronics / Computers / Laptops category and its subcategories — display 5 first Samsung tablets, sorted by price ascendant;

  • Relation Phones SAMSUNG. When opening the laptop with the manufacturer feature Samsung from the Electronics / Computers / Laptops category and its subcategories — display 5 first Samsung phones, sorted by price descendant;

  • Relation Headphones. When open any notebook from the category Electronics / Computers / Laptops and its subcategories — display 5 first headphones, sorted by price descendant.
    As a result must be next:

Example of rule creation

After saving the relation, you should create the matching rules (in unlimited number). The results for each rule are sorted in a specified way and then joined to the one products list.
If option Shuffle is set then first products will be joined to the one products list by all rules and then sorted in a specified way.

Used property types in rules:

  • Filter type → Checkbox with the following available operators: In list, Not in list;
  • Filter type → Number slider with the following available operators: Equal, Not equal, More or equal, Less or equal, In list, Not in list.

To view click the Update cache of relations button ‒ it will update all relations at once. Or update a separate relation, using gearwheel menu of the appropriate relation.

Pay attention, please, you can create the relation in the parent category and it will allow you to create only relation only that will be spread to all affiliated categories. For example, if you create the relation for parent category Computers, this relation will be present in the following affiliated categories: Desktops, Laptops, Tablets etc.

Example of parent category

If you wish you may duplicate Relation and its Rules. From the beginning duplicated relation will have a status Disabled. Edit necessary parameters, activate relation and click Update cache of relations to display it on the storefront.

linkRelation and Rule creation (Everybody should know)

To fill the block with the products automatically on the bases of relations and rules, use the following modes of products selection.

linkProducts selection mode “Without features”
linkProducts selection mode with features
linkProducts selection mode with features of Reference product (the most flexible variant)
linkProducts selection with different selection criteria in a block

link2. Relation groups by appointment in one block
link3. Relation groups by appointment in separate blocks

linkData cache

The add-on is designed for the high-loaded web stores, therefore the data cache is created, for fast product displaying. It is necessary to update cache after updating or adding products or features, prices, etc. It can be done manually or automatically. You can specify the link cache lifetime or, in other words, the time in days at which the link cache will be automatically updated. For example, every 3 days. See add-on settings.

Page "Update cache of relations"

Attention! If you have a large volume of products and relations, this process may take a long time. That's why we recommend you to use automate cache updating.

To update cache by Cron manually go to the page Administration panel → Add-ons → Downloaded add-ons and at the add-on name AB: Intellectual selection of products in block (analogues, accessories) by features in the gearwheel menu select the item Update cache of relations. On the opened page click the button Update cache of relations.

To update cache automatically, copy Cron command, specified on the page. Do not miss a chance to use a new parameter --limit, which can be used when forming the cache update command. If you have a lot of products and connections, then updating the cache for all connections at once can load the website for 100% and it will not work at all. Now, using this parameter, you can specify the number of updated links, for example 5. And in the scheduler, you can set the task for execution every 10 minutes, i.e. 6 times per hour. Therefore, in one hour you can update 6 times * 5 links = 30 links or 720 links a day and further in a circle. Such a distribution in quantity and time significantly reduces the load on the website. For example, 

5 23 * * * php /path/to/admin.php --dispatch=ab__ia_data.cron_update_cache --limit=5 --switch_company_id=*

linkFast search of Relations by all categories

For fast search of Relations by all site categories use the menu item List of reference categories:

It helps you to select already created product selection to create a new product combination.

Select the value "АВ: Products selection" in the field "Type"
