Tell us what you are trying to do?
I try to create an email list as a shortcode with the help of "toolset_get_related_posts". The emails are stored in the parent posts of a related childpost. Through $id I can access the id of the child.
But somehow $child_posts does not return any results.
add_shortcode( 'email_liste', 'func_email' );
function func_email ( $atts ){
extract( shortcode_atts( array('id' => '', ), $atts ) );
//post_id
$id = $atts['id'];
$child_posts = toolset_get_related_posts($id,'selbstportrat-reitanlagen','child',999,0,array(),'post_id','parent');
//if it returns some posts
if( $child_posts){
$emails = "Test , ";
//now get the single posts fields values
foreach( $child_posts as $single_post ){
//get each Posts post data
$single_post_data = get_post($single_post);
//get each ID
$single_post_id = $single_post_data->ID;
//get each posts field value
$email = get_post_meta($single_post_id, 'wpcf-covid-19-benutzerprofil-e-mail', true);
//we need to create a list BEFORE the if is closed and BEFORE the foreach is closed
$emails .= $email . ',';
}
// Ignore duplicates
$emails = array_unique( $emails );
}
return $emails;
}

Hello,
I suggest you debug the custom PHP codes line by line, for example:
Replace this line from:
//post_id
$id = $atts['id'];
With:
//post_id
$id = $atts['id'];
var_dump($id);
Make sure it is outputting the correct post ID value
