Polylang compatibility

And, in terms of serving a single set of results to the crp_custom_template, this piece of code can do the trick and you can simplify the code I posted above.

I will incorporate that code into my plugin in v3.0.0 which is still a while away.

function crp_template( $null, $results, $args ) {
	global $post;
	$html = '';
	$results = array_slice( $results, 0, 3 );

	$html .= '<ul class="custom_crp">';

	foreach( $results as $result ) {

		$html .= sprintf( '<li><a href="%1$s">%2$s</a></li>', get_permalink( $result->ID ), get_the_title( $result->ID ) );
	}
	$html .= '</ul>';

	return $html;
}
add_filter( 'crp_custom_template', 'crp_template', 10, 3 );

function support_polylang( $results, $args ) {
	global $post;

	$processed_ids     = array();
	$processed_results = array();

	foreach( $results as $result ) {

		$resultid = crp_object_id_cur_lang( $result->ID );

		// If this is NULL or already processed ID or matches current post then skip processing this loop.
		if ( ! $resultid || in_array( $resultid, $processed_ids ) || intval( $resultid ) === intval( $post->ID ) ) { // phpcs:ignore WordPress.PHP.StrictInArray.MissingTrueStrict
			continue;
		}

		// Push the current ID into the array to ensure we're not repeating it.
		array_push( $processed_ids, $resultid );

		$result = get_post( $resultid );    // Let's get the Post using the ID.
		array_push( $processed_results, $result );
	}
	return $processed_results;
}
add_filter( 'get_crp_posts_id', 'support_polylang', 999, 2 );

Finally, it isn’t the incentive of a donation that drives me to work on the plugin. A lot users have donated because the plugin helps them.

I’ve got a day job that is higher priority. This plugin (and others) are done pretty much in my free time – something I’ve had extremely little of. So, the donation would help pay for my time, but it can’t prioritise this over my job.

Thank you. Well received.

The second part of code will be in the next version of the plugin. I need to dig a bit into its implementation for efficiencies but I like it so far.

Changelog will likely read something along the lines of “Updated compatibility with Polylang and WPML with correct language post selected at get_crp_posts_ids”

I’ll fix the wording when it comes out. Will be in v3.0.0 so not before that.

That is next on the list as soon as as I get Add to All out in the next few days.
