IP Geo Location services supported:

• freegeoip (default)

Requirements

• Silverstripe ^5
• libphonenumber port for PHP ^8

Note: this version is compatible with SilverStripe 5. For SilverStripe 4, please see the 4 release line.

Installation

Install the module using composer:

composer require innoweb/silverstripe-international-phone-number-field dev-master

Then run dev/build.

Usage

Database field

This module provides a database field to be used for data objects:

private static $db = [
	...
	'PhoneNumber' => 'Phone',
	...
];

This stores the phone number in the database as a varchar.

In the CMS the data type Phone renders as a InternationalPhoneNumberField.

In templates, the following formatting functions are available:

• $PhoneNumber.International: Returns the phone number in international format, e.g. "+41 44 668 1800"
• $PhoneNumber.National: Returns the phone number in national format, e.g. "044 668 1800"
• $PhoneNumber.E164: Returns the phone number in international format, but with no formatting applied, e.g. "+41446681800"
• $PhoneNumber.URL or $PhoneNumber.RFC3966: Returns the phone number in international format, but with all spaces and other separating symbols replaced with a hyphen, and with any phone number extension appended with ";ext=". It also will have a prefix of "tel:" added, e.g. "tel:+41-44-668-1800".

Form field

The InternationalPhoneNumberField can be used for any Varchar field storing a phone number.

Configuration

To set the field to use the user's current location as default and customise the field, you can configure the following options for the InternationalPhoneNumberField class:

• geolocation_service: Uses IP location to determine the current users's country code. This can be 'ipstack', 'ipinfo', 'ipgeolocation' or 'freegeoip'. Defaults to 'freegeoip'.
• geolocation_api_key: API key for ipstack.com, ipinfo.io or ipgeolocation. Defaults to false.
• geolocation_protocol: Protocol to be used to connecto to geolocation service. Defaults to 'https'.
• initial_country: Country code for initially shown country in the phone number field. Defaults to 'auto', in which case the location is determined using geolocation if that's set up.
• only_countries: Array of country codes available for selection. Defaults to false, all countries are listed.
• preferred_countries: Array of country codes pushed to the top of the dropdown list. Defaults to false, all countries are listed alphabetically.
• excluded_countries: Array of country codes to be excluded from the dropdown lost. Defaults to false, all countries are listed.
