Installation

You can install this package via Composer by running the following command in the root of your WordPress project:

composer require sitesoft-be/wp-api-translator

Example Usage

1. Translate a Post on Save

use Sitesoft\WpApiTranslator\DeeplTranslator;
use Sitesoft\WpApiTranslator\WPMLPostTranslator;

require_once 'vendor/autoload.php';

function translatePost( $post_id ) {
	if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
		return;
	}

	if ( wp_is_post_revision( $post_id ) ) {
		return;
	}

	if ( get_post_type( $post_id ) !== "your_custom_post_type" ) {
		return;
	}

	remove_action( "save_post", "translatePost" );

	$deepTranslator = new DeeplTranslator( 'YOUR_DEEPL_API_KEY' );

	$wpmlTranslator = new WPMLPostTranslator( $deepTranslator );

	$wpmlTranslator->translatePost( $post_id, [ "fr", "en" ] );

	add_action( "save_post", "translatePost" );
}

add_action( 'save_post', 'translatePost' );

2. Translate ACF Fields

use Sitesoft\WpApiTranslator\DeeplTranslator;
use Sitesoft\WpApiTranslator\WPMLPostTranslator;

require_once 'vendor/autoload.php';

function translatePost( $post_id ) {
	if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
		return;
	}

	if ( wp_is_post_revision( $post_id ) ) {
		return;
	}

	if ( get_post_type( $post_id ) !== "your_custom_post_type" ) {
		return;
	}

	remove_action( "save_post", "translatePost" );

	$deepTranslator = new DeeplTranslator( 'YOUR_DEEPL_API_KEY' );

	$wpmlTranslator = new WPMLPostTranslator( $deepTranslator );

	$wpmlTranslator->translatePostACF( $post_id, [ "fr", "en" ] );

	add_action( "save_post", "translatePost" );
}

add_action( 'save_post', 'translatePost' );

Translator Configuration

1. Deepl Translator

You can use the Deepl API for high-quality translations. To configure it, replace the FakeTranslator with DeeplTranslator:

use Sitesoft\WpApiTranslator\DeeplTranslator;

$deeplTranslator = new DeeplTranslator( 'your-api-key-here' );
$wpmlTranslator = new WPMLPostTranslator( $deeplTranslator );

2. Google Translate Translator

use Sitesoft\WpApiTranslator\GoogleTranslateTranslator;

$googleTranslator = new GoogleTranslateTranslator( 'your-api-key-here' );
$wpmlTranslator = new WPMLPostTranslator( $googleTranslator );

WPML Integration

This package integrates with WPML to manage the multilingual content. It uses the wpml_set_element_language_details hook to set the language details for newly translated posts.

Supported Languages

This package supports any language that is available in the translation API you choose to use. By default, you can use any language code supported by Deepl or Google Translate.

Notes

The package relies on WPML for managing translations. Ensure WPML is installed and configured on your WordPress site. Make sure to replace API keys with your actual API credentials for Deepl or Google Translate. You may need to configure your ACF fields to ensure they are correctly translated.
