[Resolved] How to access the data stored for a entry in a post reference field using PHP?

I've created a new post reference field and I'd like to use PHP to display the title and ID of the selected post.

I've tried the standard

<?php $contributor_id2 = types_render_field("post-contributor2", array('output'=> 'normal'));?>

hoping that I'd get the ID of the selected post - but don't seem to be pulling any data at all with that function.

News Post Reference field types is not listed in API documentation yet

Hi, you can use get_post_meta in PHP to retrieve the related post's ID, then use get_the_title() to access the related post's title:

$contributor_id2 = get_post_meta( $post_id, "wpcf-post-contributor2", true);
$contributor_id2_title = get_the_title( $contributor_id2 );
echo "Post ID: " . $contributor_id2 . ", Title: " . $contributor_id2_title; 

Note that the custom field slug in get_post_meta should include the 'wpcf-' prefix.

Thanks Christian - just what I needed. Do you think you'll be creating a types_render_field() function in the future to handle this new field type?

Probably not, because the post reference custom field simply stores a post ID. You can use types_render_field to display custom field information from that related post, like if there was a select custom field and you wanted to show the selected value. The types_render_field function is not designed to display basic post information like post title, because that's not stored in the custom field. That information can be determined more efficiently using the raw post ID to query the posts table.
