WHMCS Product Setup

During the initial module activation, the wizard will create a new Product Group and Product (Product Placeholder) in your WHMCS install. Both of these are hidden by default and it does not need to be shown to your customers. 

There are few things you would want to adjust before continuing.

  1. Update the Product groups (Gift Card Group) to only allow certain type of payment. This important as you don't want to allow fraud to happen with gift cards

  2. Updating the Product,

  • You may want to change the Product Name as this will be listed in the invoice item.
  • Make sure the Welcome Email is matched with the Welcome email (Gift Card Available) the module had created during activation.
  • Tax, on or off? Some countries require Gift cards purchase to be taxed
  • Pricing, leaving it as 0.00. They will be adjusted accordingly during checkout
  • Module Settings → Module Name → Gift Card Provision Module

If you have updated the name of product placeholder, make sure you go back to the Module Configuration in Setup → Addon Modules → Configure and update to the new Product name accordingly to the Generic Product ID dropdown

Image Removed


The product and product is hidden because the module doesn't use the WHMCS system to checkout the order. However, it does use WHMCS's order system + API to manage the orders. Therefore, the Product Placeholder is needed for invoice iteming.

WHMCS Email Template Setup

The module will create the following two email templates into your WHMCS. Gift Card Available and Gift Card Sending Template

Advance Voucher Redemption Guide


We will not be providing support for any custom coding due to the complexity.

Part 1 - Template front end

If your WHMCS product require additional user input before it is provisioned, then you will need to add additional fields manually to the template.

To do this, open the  gcVoucherRedeem.tpl template. To add a new field, look at the codes under IF statement of

Code Block
{if $data["type"] == 0}

{elseif $data["type"] ==1}

You may copy and paste and use the existing code such as 

Code Block
<input type="hidden" id="requiredinputtype" value="1"/>
                                <div class="col-sm-12">
                                    <div class="form-group row">
                                        <label for="requiredinput-host" class="col-sm-2 col-form-label">{$ADDONLANG.gcPage_redeem_vc_requiredinput_1}</label>
                                        <div class="col-sm-10">
                                            <input type="text" class="form-control" id="requiredinput-host" placeholder="hostname">

Change the id so that you can distinguish it during PHP processing and Javascript validation

If you need this required input to show up with Hostname input, then put in the (["requiredinput"] == 1) condition. If show up with FQDN input, then put it in the (["requiredinput"] == 2) condition. For IP input, put it in the (["requiredinput"] == 3) condition.

If you need this required input to show up for all vouchers, then you need to create a new IF condition within the ({if $data["type"] == 0}) condition, and a ({else}) condition. 

For example,

Code Block
                           {if $data["data"]["properties"]["requiredinput"] == 1}
                             <input type="hidden" id="requiredinputtype" value="1"/>
                                <div class="col-sm-12">
                                    <div class="form-group row">
                                        <label for="requiredinput-host" class="col-sm-2 col-form-label">{$ADDONLANG.gcPage_redeem_vc_requiredinput_1}</label>
                                        <div class="col-sm-10">
                                            <input type="text" class="form-control" id="requiredinput-host" placeholder="hostname">
                            {elseif $data["data"]["properties"]["requiredinput"] == 2}
                                <input type="hidden" id="requiredinputtype" value="2"/>
                                <div class="col-sm-12">
                                    <div class="form-group row">
                                        <label for="requiredinput-fqdn" class="col-sm-2 col-form-label">{$ADDONLANG.gcPage_redeem_vc_requiredinput_2}</label>
                                        <div class="col-sm-10">
                                            <input type="text" class="form-control" id="requiredinput-fqdn" placeholder="">
                            {elseif $data["data"]["properties"]["requiredinput"] == 3}
                                <input type="hidden" id="requiredinputtype" value="3"/>
                                <div class="col-sm-12">
                                    <div class="form-group row">
                                        <label for="requiredinput-ip" class="col-sm-2 col-form-label">{$ADDONLANG.gcPage_redeem_vc_requiredinput_3}</label>
                                        <div class="col-sm-10">
                                            <input type="text" class="form-control" id="requiredinput-ip" placeholder="">
								**Your new codes

If you need the required input to show up for a particular voucher mapping then you can perform a IF condition such as 

Code Block
{if $data["data"]["id"] == X}


Where X is the voucher's ID. 

Once you have added the fields, you may want to add additional Javascript validation.

Part 2 - PHP Backend


Do not allow user input without running some sort of validation of user's input. 

You will want to run some validation in the backend before it is inserted into your database. To do this, open the following file

Code Block

This file is not encoded. There for you can make any changes you need for New Service redemption that require additional user input.

The codes are in the redemptionProcessHook function. 

You can refer to the WHMCS AddOrder API guide for additional information.

That's it. You new codes should be running for your new inputs.

Running codes after successful Renewal Redemption

If you run any custom code after a user successfully redeemed a voucher, simply open the following file.

Code Block

then you can insert your own code in the redemptionRenewalHook function.

The $vars variable contains the following

Code Block
$vars = array("uid"=>$_SESSION['uid'],"vcdata"=>$vcdata);

$vcdata are the voucher's properties which you can locate it in the mod_giftcard_voucher table in the database

$serviceid is the service id of the user chose to extend the renewal to.

Gift Card Listing

In order for the module to work in the front end, you must have at least one Gift Card available for purchase.

New Service Voucher

For vouchers set to New Service, the voucher redeemer can obtain a new service available in your WHMCS. The billing cycle for these type of voucher falls in line with the billing cycle available in WHMCS. 

With New Service Vouchers, you may require the redeemer to input a value (either a hostname or domain name) before a redemption is allowed. The input will be used in the domain field of the service. 

If you need additional value to be inputted by the user, please refer to the Advance Voucher Redemption Guide

Renewal Service Voucher

For vouchers set to Renewal, the voucher redeemer can extend their existing service within their account. The billing cycle for these type of vouchers are in line with the WHMCS billing cycle except for One Time. An additional cycle called Lifetime is available for renewal vouchers. When a user redeem a Lifetime voucher, their existing service will be updated to a One Time service and no further billing will occur for this service.
