WP Discourse WooCommerce Support

This plugin allows you to integrate the WP Discourse plugin with WooCommerce.

What it does

• hooks into the woocommerce_login_redirect and woocommerce_registration_redirect filter to add the query parameters to the redirect path that are required for Discourse Single Sign On to work.
• hooks into the woocommerce_product_get_review_count filter so that Discourse comments are used for the review count.

How to make it work

This plugin depends on both having a Discourse forum and on having the WP Discourse plugin installed and actived on your site.

If you have enabled Discourse SSO on your site, to use a WooCommerce login page as your site's main login or registration page requires setting the login path option in the WP Discourse settings. The login path option is found under the SSO tab of the WP Discourse settings page. If you would like your login page to be at http://example.com/my-account, then the login path in the WP Discourse settings should be set to /my-account. It also requires enabling the registration function on the WooCommerce my-account page via Woocommerce --> Settings --> Accounts & Privacy.

Installation

To install this plugin, download a zip file of it from this page and then install it through your site's admin section.

Alternatives to installing the plugin

For now, the plugin only contains two functions. If you prefer, you can just add these functions to your theme's functions.php file:

/**
 * Sets the login redirect so that it can include the query parameters required for single sign on with Discourse.
 *
 * @param string $redirect The redirect URL supplied by WooCommerce.
 *
 * @return mixed
 */
function my_namespace_wp_discourse_woocommerce_redirect( $redirect ) {
	if ( isset( $_GET['redirect_to'] ) && esc_url_raw( wp_unslash( $_GET['redirect_to'] ) ) ) { // Input var okay.
		$redirect = esc_url_raw( wp_unslash( $_GET['redirect_to'] ) ); // Input var okay.

		return $redirect;
	}

	return $redirect;
}
add_filter( 'woocommerce_login_redirect', 'my_namespace_wp_discourse_woocommerce_redirect' );
add_filter( 'woocommerce_registration_redirect', 'my_namespace_wp_discourse_woocommerce_redirect' );

/**
 * Replaces the WooCommerce comments count with the Discourse comments count.
 *
 * @param int $count The comments count returned from WooCommerce.
 *
 * @return mixed
 */

function my_namespace_wp_discourse_comments_number( $count ) {
	global $post;
	$discourse_post_id = get_post_meta( $post->ID, 'discourse_post_id', true );

	if ( $discourse_post_id > 0 ) {
		$count = get_post_meta( $post->ID, 'discourse_comments_count', true );

		return $count;
	}

	return $count;
}
add_filter( 'woocommerce_product_review_count', 'my_namespace_wp_discourse_comments_number' );
