README

This plugin adds location based features to Winter CMS.

Supports:

Easily add Country and State to any model
Form widget for address lookups (Google API)

Installation

This plugin is available for installation via Composer.

composer require winter/wn-location-plugin

After installing the plugin you will need to run the migrations and (if you are using a public folder) republish your public directory.

php artisan migrate

Google API key requirement

As of June 22, 2016 the Google Maps service requires an API key. You may generate a key from the following link:

Get a Google API key

Copy the key and enter it in the Settings > Location settings area. If you find the address finder is not working, you may need to enable the Places API and the Maps JavaScript API.

Add Country and State to any model

This plugin provides an easy way to add location fields, country and state, to any model. Simply add these columns to the database table:

$table->integer('country_id')->unsigned()->nullable()->index();
$table->integer('state_id')->unsigned()->nullable()->index();

Then implement the Winter.Location.Behaviors.LocationModel behavior in the model class:

public $implement = ['Winter.Location.Behaviors.LocationModel'];

This will automatically create two "belongs to" relationships:

state - relation for Winter\Location\Models\State
country - relation for Winter\Location\Models\Country

Back-end usage

Forms

You are free to add the following form field definitions:

country:
    label: winter.location::lang.country.label
    type: dropdown
    span: left
    placeholder: winter.location::lang.country.select

state:
    label: winter.location::lang.state.label
    type: dropdown
    span: right
    dependsOn: country
    placeholder: winter.location::lang.state.select

Lists

For the list column definitions, you can use the following snippet:

country:
    label: winter.location::lang.country.label
    searchable: true
    relation: country
    select: name
    sortable: false

state:
    label: winter.location::lang.state.label
    searchable: true
    relation: state
    select: name
    sortable: false

Front-end usage

The front-end can also use the relationships by creating a partial called country-state with the content:

{% set countryId = countryId|default(form_value('country_id')) %}
{% set stateId = stateId|default(form_value('state_id')) %}

<div class="form-group">
    <label for="accountCountry">Country</label>
    {{ form_select_country('country_id', countryId, {
        id: 'accountCountry',
        class: 'form-control',
        emptyOption: '',
        'data-request': 'onInit',
        'data-request-update': {
            'country-state': '#partialCountryState'
        }
    }) }}
</div>

<div class="form-group">
    <label for="accountState">State</label>
    {{ form_select_state('state_id', countryId, stateId, {
        id: 'accountState',
        class: 'form-control',
        emptyOption: ''
    }) }}
</div>

This partial can be rendered in a form with the following:

<div id="partialCountryState">
    {% partial 'country-state' countryId=user.country_id stateId=user.state_id %}
</div>

Short code accessors

The behavior will also add a special short code accessor and setter to the model that converts country_code and state_code to their respective identifiers.

// Softly looks up and sets the country_id and state_id
// for these Country and State relations.

$model->country_code = "US";
$model->state_code = "FL";
$model->save();

ISO 3166-1 accessors

The behavior will also add the ISO-3166-1 values as accessors to the model (data sourced from the league/iso3166 package).
Availables accessors are iso_name (country name), iso_alpha3 (three-letter code), iso_numeric (three-digit code), iso_currencies (three-digit currencies code) and iso (array of all iso attributes).

$usCountry = \Winter\Location\Models\Country::whereCode('US')->first();

$usCountry->iso_name;
// (string) "United States of America"

$usCountry->iso_alpha3;
// (string) "USA"

$usCountry->iso_numeric;
// (string) "840"

$usCountry->iso_currencies;
// (array) [ 0 => "USD" ]

$usCountry->iso;
// (array) [
//     "name" => "United States of America"
//     "alpha2" => "US"
//     "alpha3" => "USA"
//     "numeric" => "840"
//     "currency" => [
//         0 => "USD"
//     ]
// ]

Address Finder Form Widget

This plugin introduces an address lookup form field called addressfinder. The form widget renders a Google Maps autocomplete address field that automatically populates mapped fields based on the value entered and selected in the address.

Available mappings:

street
city
zip
state
country
country-long
latitude
longitude
vicinity

Available options:

You can restrict the address lookup to certain countries by defining the countryRestriction option. The option accepts a comma separated list of ISO 3166-1 ALPHA-2 compatible country codes (see: https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2).
