README

A WordPress library for Maps.co Geocoding API integration with smart caching and comprehensive location data handling.

Installation

Install via Composer:

composer require arraypress/mapsco-geocoding

Requirements

• PHP 7.4 or later
• WordPress 6.2.2 or later
• Maps.co API key

Basic Usage

use ArrayPress\MapsCo\Geocoding\Client;

// Initialize with your API key
$client = new Client( 'your-api-key-here' );

// Forward geocoding (address to coordinates)
$location = $client->geocode( '1600 Pennsylvania Avenue NW, Washington, DC' );

// Reverse geocoding (coordinates to address)
$location = $client->reverse_geocode( 38.8977, -77.0365 );

Available Methods

Client Methods

// Initialize client with options
$client = new Client(
	'your-api-key-here',  // API key
	'json',              // Response format (optional, default: 'json')
	true,               // Enable caching (optional, default: true)
	604800             // Cache duration in seconds (optional, default: 1 week)
);

// Forward geocoding
$location = $client->geocode( '1600 Pennsylvania Avenue NW, Washington, DC' );

// Reverse geocoding
$location = $client->reverse_geocode( 38.8977, - 77.0365 );

// Cache management
$client->clear_cache( 'address_key' );  // Clear specific cache
$client->clear_cache();                 // Clear all cached geocoding data

Error Handling

The library uses WordPress's WP_Error for error handling:

$location = $client->geocode( 'invalid address' );

if ( is_wp_error( $location ) ) {
    echo $location->get_error_message();
    // Output: "No results found for the provided address"
}

Common error cases:

• Invalid address
• Invalid coordinates
• Invalid API key
• API request failure
• No results found
• Invalid response format
