“Main” Item from a Relationship Field

    Hey,

    I have a CPT created with Pods called Song and another one called CD. Some songs are attached to more than one CD. Is it possible to set a “main” CD that I could use, for example, in a breadcrumbs or whatever? Just like when you select more than one category in a WordPress post then you can choose the “main” one.

    If that’s not possible, is there some alternative? Is there a function or something to attach to a {@CD,some_function} in a pod template to get just that “main” CD?

    With this PHP function defined in your theme’s functions.php or a plugin:

    function link_to_first_post( $posts ) {
	if ( empty( $posts ) ) {
		return '';
	}
	ob_start();
	?>
	<a href="<?php echo esc_url( get_permalink( $posts[0]['ID'] ) ); ?>">
		<?php echo esc_html( get_the_title( $posts[0]['ID'] ) ); ?>
	</a>
	<?php
	return ob_get_clean();
}

    The shortcode/magic tag would be: [pods]{@cd,link_to_first_post}[/pods]

    Hi @junkes

    I personally would create an extra field for such a purpose.
    However you could use @pdclark code and set the first relationship as the “main” item.

    Cheers, Jory

    Hey, @pdclark, that worked as a charm, thank you very much. I wonder if it’s possible to do that not with post_title but another field in CD…
