How do I print custom user fields?
Assuming this information is from the user profile.

You could do the following

blend.theme

function blend_preprocess_node(&amp;$variables){
    $node = $variables['node'];
    $variables['firstname'] = $node-&gt;getOwner()-&gt;field_first_name-&gt;value;
    $variables['lastname'] = $node-&gt;getOwner()-&gt;field_last_name-&gt;value;
}


From there you can use {{ firstname }} and {{lastname}} anywhere in your template.
