“total_pods”, but with a relationship field filter

Hello @stefancom

You already answered your own question in this case ??
The field() method is indeed the best way to do this.
Just take your example and instead of the foreach loop you can use count() (https://www.php.net/manual/en/function.count.php) to get the total related items.

Hey Jory @keraweb

Thank you very much for your comment!

So, I guess first of all the first part of my tries must go, yes? I base the solution fully on the Get Values from a Custom Relationship Field snippet?

<del datetime="2020-08-11T15:57:27+00:00"><?php
function total_pods($atts , $content = null ) {
	extract(shortcode_atts(
        array	(
				'my_pod' => ''
				), $atts));
				
	$my_pods = pods( $my_pod , array( 'limit' => -1 ) );
	return $my_pods->total_found();
	}
add_shortcode( 'count_pods', 'total_pods' );
?>

<p>Number of Concerts: [count_pods my_pod ='concerts']</del>

<?php 
    	//get Pods object for current post
    	$pod = pods( 'concerts', get_the_id() );
	//get the value for the relationship field
	$related = $pod->field( 'composition' );
	//loop through related field, creating links to their own pages
	//only if there is anything to loop through
	if ( ! empty( $related ) ) {
		count ( $related as $rel ) { 
			//get id for related post and put in ID
			//for advanced content types use $id = $rel[ 'id' ];
			$id = $rel[ 'ID' ];
			//show the related post name as link
			echo '<a href="'.esc_url( get_permalink( $id ) ).'">'.get_the_title( $id ).'</a>';
			//get the value for some_field in related post and echo it
			$someField = get_post_meta( $id, 'some_field', true );
			echo $someField;
		} //end of foreach
	} //endif ! empty ( $related )
?>

That would me leave with the code above, yes? I changed the the pod name and the relationship field name to my case.

But then, WordPress confronts me with an error (Parse error: syntax error, unexpected ‘as’ (T_AS), expecting ‘)’ in code on line 9). Has that to do with $related as $rel, now that I changed foreach to count? That probably is not right?

Furthermore, this code is to echo a list, right? But, how could I make it echo a mere number instead? With something like echo count($related);?

Would the $id = $rel[ ‘ID’ ]; bit even be necessary for what I intend, like, maybe I should shorten the code even more?

Best,

Stefan

Postscriptum: The formatting of the code was not a good idea. Here I paste it again, including the formatting:

<?php
function total_pods($atts , $content = null ) {
extract(shortcode_atts(
array (
‘my_pod’ => ”
), $atts));

<?php
//get Pods object for current post
$pod = pods( ‘concerts’, get_the_id() );
//get the value for the relationship field
$related = $pod->field( ‘composition’ );
//loop through related field, creating links to their own pages
//only if there is anything to loop through
if ( ! empty( $related ) ) {
count ( $related as $rel ) {
//get id for related post and put in ID
//for advanced content types use $id = $rel[ ‘id’ ];
$id = $rel[ ‘ID’ ];
//show the related post name as link
echo ‘‘.get_the_title( $id ).’‘;
//get the value for some_field in related post and echo it
$someField = get_post_meta( $id, ‘some_field’, true );
echo $someField;
} //end of foreach
} //endif ! empty ( $related )
?>

O.K., this too was not a good idea. I hope you can see what my code quote was intended to be about.

Hi @stefancom

I’m not exactly following your comments at the moment.

Please read the documentation about count() from PHP:
https://www.php.net/manual/en/function.count.php

This is incorrect:
count ( $related as $rel )

Count is a function, not a loop or anything:
$total = count( $related );
