This tutorial will show you how to successfully set up Geolocation Hook For WHMCS.

Upload the files and then move to the configuration section to learn how to take the most from it.


In this tutorial we will show you how to successfully install the hook.

We will guide you step by step through the whole installation and configuration process.

1. Log in to our client area and download the hook.

2. Extract the downloaded file and upload it into the main WHMCS directory.

The content of the file should look like this.

That is all! You do not need to install or activate it in any place!


Let us proceed to the hook configuration. Move to yourWHMCS/Includes/Geolocation directory and open the config.php file.
Configure the file that will be called on selected pages of the client area in your WHMCS System. Underneath, you will find a detailed instruction on how to configure it step by step.
1. Define the currency and language rules.

The below code snippet is responsible for assigning an appropriate currency to a client who uses pointed here language.
In the example below we can see that a client who uses the US language, will have the USD currency automatically turned on.
You may now edit this code snippets with our own configuration and add new entries under GB example if needed.
Use the same pattern to configure language for every used country.
Important: Every code line must end with a comma. Do not forget to type it if you decide to add new lines.

 $countryToCurrency = array(
   'default' => 'USD',
   'US'      => 'USD',
   'GB'      => 'GBP',
   // NOTE: You can add more below
 $countryToLanguage = array(
   'default' => 'english',
   'US'    => 'english',
   'DE'    => 'german',
   'NO'    => 'norwegian',
   // NOTE: You can add more below

2. Define additional template per country and language rules.

We can now configure additional settings: templates per country and language rules. Assign an existing in your WHMCS system template to a country.
Again, edit the exemplary code lines and add new lines if needed. Do not forget about the comma.

 $countryToTemplate = array(
   'US'  => 'six',
   'default' => 'six',
   // NOTE: You can add more below
* Now, define the language for each WHMCS template used.
* Please note that a template available in WHMCS V7 is: 'six'.
* It is important to use a template that exists within your WHMCS system.
* Not Logged In Users 
$templateToLanguage = array(
   'english' => 'six',
   'german'  => 'six',
   'default' => 'six',
       // NOTE: You can add more below

3. Mobile template per a mobile device.

The next part is dedicated to automatic adjustment of a template based on the device that is being used to enter the client area.
In case your WHCMS does not use a responsive template that will automatically adjust to the device size, you may force the template change to aone designed for such device.
Uncomment the below lines and enter the existing templates names for tablets and mobiles to turn on this option.

$mobileToTemplate = [
   'mobile' => 'mobile_template',
   'tablet' => 'tablet_template',

4. Define templates per domain name.

Depending on the domain name that a client enters a template will be adequately altered. Uncomment, edit and add new lines using the presented pattern.

$domainToTemplate = [
   //'' => 'mobile_template',
   //'' => 'six',

5. Selecting Pages

At this point we can select pages in your WHMCS where the geolocation hook should be activated.
Comment any lines if you do not want to use the hook there, add other pages at the bottom.

 $allowedScripts = array(
   // NOTE: You can add more below

6. Point single IP addresses. The hook will be turned off for these addresses.

Uncomment, edit and add new lines using the presented pattern.

$disabledForIPs = array(
//    '',
//    '',
       // NOTE: You can uncomment or add more below

7. Point full IP pools. The hook will be turned off for the addresses in these pools.

Uncomment, edit and add new lines using the presented pattern.

$disabledForCidrIPs = array(
//    '',
//    '',
//        NOTE: You can uncomment or add more below

8. Point user agents. The hook will be turned off for the enumerated here devices/browsers.

The user agent can be provided in two forms:

  • short form, e.g.: 'Chrome'
  • full version, e.g.: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36')'.

Uncomment, edit and add new lines using the presented pattern.

$disabledForBrowsers = array(
//    'Chrome',
//    'Firefox',
//    'Google-Site-Verification',
//    'Mozilla/5.0 (compatible; Googlebot/2.1; + )',
//    'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 7.1; Trident/5.0)',
//     NOTE: You can uncomment or add more below

9. Getting Country With MaxMind GeoIP2

The example below shows the integration with MaxMind GeoIP2.
You may surely create your own submodule, edit the below line in such case as only one submodule can work at a time.

 $submodule = 'GeoIP2';

10. Determining Template Setup

We will use the following code to determine whether a current template is set up correctly.

* Currency Session Setup
 $allowCurrencySession = true;
* Setting up a template to redirect depending on a country
 $allowRedirectCountryToTemplate = false;
* Setting up a template to redirect depending on a language
 $allowRedirectLanguageToTemplate = true;

11. Creating URL Redirection

The system will be forced to switch the client area template depending on the chosen language. It will also work for already logged in users.
Redirection needs to be executed when switching the language is done by a user or together with changing the language.

* Setting up URL redirection to allow the user to switch a language
 $allowURLRedirection = true;
* Change template if
* - current template is NOT correct for this language
* - current template is NOT default if no language was chosen
 $changeTemplateByLanguage = true;
* Preventing from switching currency by user
 $preventSwitchCurrency = true;
* Preserve Template
* This option, when set as false, allows template switch along with the language change
 $preserveTemplate = true;
