[Plugin: Posts 2 Posts] update_post_meta not working as i expected

Resolved

(@sergio_soares)

Hello m8s.

I Need to save a value of a Connection on a custom field.

I did this:

<?php
function cria_campos() {
global $post;
$relacionadocasa = new WP_Query( array(
	  'post_type' => 'casa-espectaculo',
	  'connected' => $post->ID
	) );
	while ($relacionadocasa->have_posts()) : $relacionadocasa->the_post();

	$local_evento = $relacionadocasa->post_title;

	endwhile;
update_post_meta($post->ID, 'local_evento', $local_evento);
}
add_action('publish_post', 'cria_campos');
?>

Nothing is saved.

What i’m doing wrong?

The relationship is between post and ‘casa-espectaculo’ and i want to save to a custom field the value of the post title from casa-espectaculo post type.

Help me pls. Sorry about some erros writing english

Shouldn’t update_post_meta() be before endwhile (i.e. in the loop)?

Also, I think you’d be better off using get_posts(). Remember to set 'suppress_filters' => false

	foreach ($relacionadocasa as $relacionado) : setup_postdata($relacionado);
		$local_evento = 'teste';
		update_post_meta($post->ID, 'local_evento', $local_evento);

on template i made like this:
```
<?php
// post
global $post;
$relacionadopost = new WP_Query( array(
'post_type' => 'post',
'connected' => $post->ID
) );
if($relacionadopost) {
echo '<h3>Informação Relacionada</h3>';
}
while ($relacionadopost->have_posts()) : $relacionadopost->the_post(); ?>

<?php $local_evento = get_post_meta($post->ID, 'local_evento', true); ?>

<?php echo $local_evento; ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a><?php echo $casa; ?><br/>

<?php
endwhile;
wp_reset_postdata();
?>
```
no output is returned on variable $local_evento

Looking at this again, I don’t see why you would need to store the titles as custom fields in the first place.

See https://github.com/scribu/wp-posts-to-posts/wiki/Looping-The-Loop
