Configuration and Management

Product Linker For WHMCS allows to sell bundles of products through ordering one product with specific product addons and configurable options. It also automatically forwards basic commands from the main product to all child products. You can define the relationship between products through a product add-on or configurable option.

Basic Relations

At the 'Basic Relations' tab you can define links between products through product addons and configurable options. They will be triggered once your client makes an order for a product with the product addon/configurable option chosen at the relation. Additionally, you can define a discount added to the order by triggering the relation. To add a new relation, go to 'Relations' → 'Basic Relations' and click on 'Add Relation'.

To set up a relation: Type - Choose a relation type from the 'Type' dropdown menu, selecting either a relation triggered by a product addon or a configurable option. Addon/Configurable Option - Select a product addon or configurable option that will trigger the relation. Swap Price - If you select the 'Addon' type, you can also enable the 'Swap Price' option, which will overwrite the price of the linked product with the addon price. Configurable Option Value - if you choose the 'Configurable Option' relation type, you must also select a specific configurable option. Linked Product - select a child product that will be linked after the relation is triggered. This product should be set to 'hidden' and 'free'. Promotion - optionally, choose a discount that will be added to the order. Note: Keep in mind that only one discount can be assigned to an order, and you can manage discount assignments on the 'Settings' page. Copy Custom Fields - decide if you want Custom Fields copied from the main product to the linked product. Note: The Custom Fields are copied from the main product, not from the addon.

Added relations can be edited or deleted by using the relative action buttons.

Product Relations

At the 'Product Relations' tab you can set up a relation linking one product with another. To create a new configuration simply click on the 'Add Relation' button.

Provide the following information to create the relation: Main Product - choose a product from the 'Main Product' dropdown menu to trigger the relation. Linked Product - select a product from the 'Linked Product' dropdown menu that will be added when the relation is triggered. This product should be set to 'hidden' and 'free'. Promotion - optionally, assign a promotion. Configurable Option Groups - select configurable options to transfer values for. Note: Configurable option copying can only be enabled if the configurable option is assigned to both the parent and child products. Copy Custom Fields - decide if you want Custom Fields copied from the main product to the linked product.

Created product relations can be edited or deleted by clicking on the respective action buttons.

Existing Connections

'Existing Connections' tab allows you to view the list of all products ordered by your clients for which relations exist. You can find all the information about a relation, like the main product, linked product, their owner, or domain used by both products. If a need arises, you can also delete a connection and optionally terminate the linked product. Note: Keep in mind that 'Suspend', 'Unsuspend' and 'Terminate' actions performed on the Main Product will be reflected on the Linked Product.

Settings

Due to the assignment of promotions to the relation, a situation may occur where multiple promotions will be assigned to one order. WHMCS does not support such a situation, therefore only one promotion has to be chosen. Highest Discount - the promotion giving the highest discount to your clients will be chosen in the order form. Lowest Discount - the promotion giving the lowest discount to your clients will be chosen in the order form. Minimum Reduction Amount - if the 'Lowest Discount' is selected, provide the lowest reduction value (order subtotal * promotion rate) that can be used. If the promotion value is below the limit, a higher discount will be applied until the provided amount is met or exceeded. Display Product Info - information about the linked product will be visible on the order form when this option is enabled. Minimum Reduction Amount Example: Client's order qualifies for 3 discounts: 20%, 50% and 80% We have set the Discount Priority to 'Lowest Discount' The Minimum Reduction Amount is set to '10' The order subtotal is '36.39' The reduction is calculated: 36.39 * 20% = 7.28 36.39 * 50% = 18.20 36.39 * 80% = 29.11 Since the calculation with the lowest discount did not exceed the 'Minimum Reduction Amount', the next discount (50%) is applied as it does exceed the minimum.

Queue

The 'Queue' section is designed to handle product upgrades and downgrades for products that have a relation established. The cron will automatically create tasks to terminate linked products after upgrade/downgrade of the main product. If you allow your clients to upgrade/downgrade products that you have created relations for, it is recommended to run a dedicated cron job every 5 minutes: php -q /your_WHMCS/modules/addons/ProductLinker/cron/cron.php queue The table below the cron job information will allow you to see the status of each task, see its details, run it manually, or delete it.

You can delete multiple tasks at once by using the mass action function.

Additional actions include the auto prune system and the ability to hide the cron information.

Translations

Customizing language files is now extremely easy with the "Translations" tool that is now available directly in the addon. Its user-friendly design makes managing various language file tweaks a smooth and efficient process. Prepare translations for the original English files with this handy built-in tool. For specific instructions on how to use this tool please refer to its dedicated article, you will find it here.

Logs

The 'Logs' page stores the history of actions performed by the module. Use the action buttons to see details or delete each log entry. Multiple logs can be deleted at once by utilizing the mass selection function.

Furthermore, the logs feature additional actions. Changing the logs' settings, exporting the logs to a '.csv' file, and a way to delete specific log types.

In the settings you can specify which log types should be recorded, and whether they should be deleted automatically after a specific time.

While exporting you will pick a time frame and the log types to export.

Here you can decide which log types to delete, you can also specify how old the logs have to be to qualify for deletion. Leave the first field empty to delete all logs.

Client Area

When the client orders a product with a relation created for it, the relation will be displayed on the order form, provided the option is enabled in the addon's settings. If included in the relations, promotions will be applied based on the settings.

Use Cases

This section provides scenarios that demonstrate common use cases, along with detailed explanations of how the module’s features can be utilized in real-world situations. Review the following examples to understand better how the module can be applied in practice.

Basic Relation: Proxmox VE VPS and cPanel Manage2

In these steps, we will show you how to link Proxmox VE VPS with cPanel Manage2 through a product addon. You can also link them using configurable options if you would prefer. 1. First create the product addon which will trigger the relation. Go to 'System Settings' → 'Products/Services' → 'Products Addons' and press 'Add New Addon'.

2. Name your addon, there is no need to select a module since the addon will only be used to trigger the relation for the cPanel Manage2 Product to be added.

3. Make sure you check the 'Show on Order' checkbox under 'Details'.

4. It is advised to set up the same billing cycle as in the main product. The price of the addon will effectively be the price of the linked product.

5. Finally, select the main product which the addon will be available for, in this case, it is 'Proxmox VE VPS KVM'. Next, press 'Save Changes'.

6. Now, create a relation at your 'Product Linker' → 'Relations' → 'Basic Relations'.

Configure the relation: Type - select 'Addon' for this example. Addon - select your newly created addon. Swap Price - Leave this option disabled. Linked Product - Select the product that will be added when the relation is triggered. It should be set to hidden and free. You have indirectly set its price at the product addon configuration. Promotion - include a promotion, if you would like, you can add new promotions under 'System Settings' → 'Payments' → 'Promotions'. Copy Custom Fields - Leave disabled unless you want to copy custom fields from the main product to the linked product.

To check if the relation works as it should, place an order from the admin area for the main product with the product addon triggering the relation.

The linked product will be added to the order along with the main product.

Product Relation: Proxmox VE VPS and Plesk Key Administrator

In these steps, we will show you how to link independent Proxmox VE VPS and Plesk Key Administrator products. The linked product will always be added when the main product is ordered.

Create a relation at your 'Product Linker' → 'Relations'. → 'Product Relations'.

Configure the relation: Main Product - select the main product which will trigger the relation on its own. Linked Product - Select the product that will be added when the relation is triggered. It should be set to hidden and free. You can indirectly set its price by balancing the main product price and the promotion. Promotion - include a promotion, if you would like, you can add new promotions under 'System Settings' → 'Payments' → 'Promotions'. Copy Custom Fields - Leave disabled unless you want to copy custom fields from the main product to the linked product.

To check if the relation works as it should, place an order from the admin area for the main product with the product addon triggering the relation.

The linked product will be added to the order along with the main product.

Tips

1. If your client orders a product with settings triggering two relations with the same product, only one product will be created.

2. If your client orders a product configurable options upgrade/downgrade, the old linked product bound by a previous configurable option will stay active. You need to remove the link between the old linked product and the main product in the addon and terminate the old linked product manually.

3. If a child product is at the same time a parent product in the other relation, changes made on its parent will be also commanded on its child.

4. Keep in mind that the second product, linked by the module, is never visible in the cart. It is automatically added once the first one is ordered.
