Product short description doesn’t handle page builder shortcodes

Overview of the issue

The WooCommerce product short description is based on the post excerpt field, and that is ordinarily a simple text field that does not handle shortcodes. As such it is not expected that if you paste page-builder shortcodes into the post excerpt they would work, and when translating post excerpts WPML does not attempt to handle such shortcodes.

But WC handles these “excerpts” a little differently, and shortcodes do work, but WPML still acts as if they do not, and if the shortcode includes attributes that need translating or internal links that should be handled automatically that is not readily possible.

Workaround

We have prepared code that can be added as a plugin to provide this functionality. Copy and paste the below code into a file that you might name wpmlpb-excerpts.php and save in your wp-content/plugins/ directory, then activate the plugin.

<?php
/**
 * Plugin Name: WPML Page Builders - Proces Excerpts
 * Description: Parses shortcode strings in exceprts.
 * Version: 1.0
 */
namespace WPMLPB686;

( new Excerpts() )->add_hooks();

class Excerpts {

	const SEPARATOR_START = '<!--WPML_EXCERPT_START-->';
	const SEPARATOR_END   = '<!--WPML_EXCERPT_END-->';

	public function add_hooks() {
		add_filter( 'wpml_pb_shortcode_content_for_translation', [ $this, 'joinWithContent' ], 10, 2 );
		add_filter( 'wpml_tm_translation_job_data', [ $this, 'excludeFromJob' ], 10, 2 );
		add_action( 'wpml_pro_translation_completed', [ $this, 'splitFromContent' ], 999 );
	}

	public function joinWithContent( $content, $id ) {
		$post = get_post( $id );
		if ( $post && $post->post_excerpt ) {
			$content .= self::SEPARATOR_START . $post->post_excerpt . self::SEPARATOR_END;
		}

		return $content;
	}

	public function excludeFromJob( $package, $post ) {
		if ( preg_match( '/[[^]]+]/', $post->post_excerpt ) ) {
			$package['contents']['excerpt']['translate'] = 0;
			$package['contents']['excerpt']['data']      = '';
		}

		return $package;
	}

	public function splitFromContent( $post_id ) {
		$post = get_post( $post_id );
		if ( $post && false !== strpos( $post->post_content, self::SEPARATOR_START ) ) {
			$start_pos = strpos( $post->post_content, self::SEPARATOR_START );
			$end_pos   = strpos( $post->post_content, self::SEPARATOR_END, $start_pos );

			if ( false !== $end_pos ) {
				$content = substr( $post->post_content, 0, $start_pos );
				$excerpt = substr( $post->post_content, $start_pos + strlen( self::SEPARATOR_START ), $end_pos - $start_pos - strlen( self::SEPARATOR_START ) );

				if ( $excerpt ) {
					wp_update_post(
						[
							'ID'           => $post_id,
							'post_content' => $content,
							'post_excerpt' => $excerpt,
						]
					);
				}
			}
		}
	}
}
