Get content from related post

Hi Ralf,

I’m sorry, but I don’t understand what you want to achieve. And your code doesn’t make much sense either, to be honest. ??

You have posts in German, which have additional metadata (image gallery and energy certificate) that seems to be language-independent, and that’s why you want to switch to the German site (or to be more precise: post), fetch the according data, display it, and then switch back and continue with the original (French) post. Is this right so far?

Kind regards,
Thorsten

Hi Thorsten,

sorry for being unprecise. What I want to reach is that:

• Display French Content, e.g. description, price an so on
• Image gallery: no content found on French site, so switch to German blog
• Get images from German blog and display them on the French site
• switch back to French site and display the rest of the French content

This is the code used on the German site to get the images from my custom field “Image gallery”:

<?php
$images = get_field('images');

if( $images ): ?>

  <hr>
    <div class="image-gallery clearfix">
        <?php foreach( $images as $image ): ?>
                <a title="<?php echo get_the_title(); ?>" class="fancybox" data-fancybox-group="post-<?php get_the_ID(); ?>" href="<?php echo $image['url']; ?>">
                     <img class="alignleft" src="<?php echo $image['sizes']['thumbnail']; ?>" alt="" />
                </a>
                <div class="wpcasa-caption"><?php echo $image['caption']; ?></div>
        <?php endforeach; ?>
    </div>
  <hr>
<?php endif; ?>

The second code mentioned above was just an example what I am planning. I know that this one doesn’t make any sense ??

Thanks again for your help.
Ralf

Hi Ralf,

I don’t have ACF, so I couldn’t test this, but here’s how it should be done:

// This is the ID of your "base" site, which is the German one with ID 1.
$base_site_id = 1;

$switched_site = false;

$translation = null;

$is_base_site = get_current_blog_id() === $base_site_id;
if ( ! $is_base_site ) {
	$translations = mlp_get_linked_elements( get_the_ID() );
	if ( ! empty( $translations[ $base_site_id ] ) ) {
		switch_to_blog( $base_site_id );
		$switched_site = true;

		$translation = get_post( $translations[ $base_site_id ] );
		if ( $translation ) {
			$GLOBALS['post'] = $translation;
		}
	}
}

if ( $is_base_site || $translation ) {

	// Okay, we either are on the German (base) site, or we are on the French one AND found a valid German translation.
	// Here, you can also fetch and display the energy certificate...

	$images = get_field( 'images' );
	if ( $images ) : ?>
		<hr>
		<div class="image-gallery clearfix">
			<?php foreach ( $images as $image ) : ?>
				<a href="<?php echo esc_url( $image['url'] ); ?>" title="<?php the_title_attribute(); ?>" class="fancybox" data-fancybox-group="post-<?php the_ID(); ?>">
					<img src="<?php echo esc_url( $image['sizes']['thumbnail'] ); ?>" class="alignleft" alt="">
				</a>
				<div class="wpcasa-caption"><?php echo $image['caption']; ?></div>
			<?php endforeach; ?>
		</div>
		<hr>
	<?php endif;
}

if ( $switched_site ) {
	restore_current_blog();
	wp_reset_postdata();
}

I also improved your code: use the_title_attribute() instead of the_title(), escape data (!), use the_ID() instead of get_the_ID(), which doesn’t echo, …

Kind regards,
Thorsten

Hi Thorsten,

it seems that we both have written at the same time ?? Thanks for your code example, I will check this one out and reply soon.

Regards
Ralf

This piece of code works great ??
Thanks for your help, Thorsten.

Ralf

Hi Ralf,

you’re welcome. Glad it worked for you.

Would you mind writing a short review for MultilingualPress?
This would mean a lot to us. And with better (and more) reviews, MultilingualPress might get more popular, which in turn means more users, and thus eventually highly motivated developers and supporters. ??

Best regards,
Thorsten

Hi Torsten,

done ??
Keep your good work and your excellent support.

Regards
Ralf

Wow, thanks a lot! ??
