Display in node custom field profile

Question

I created a custom field in the users profiles.

I need to display in node.tpl.php, this field for the author of the node.

I tried :

<?php 
print $node_author = user_load($node->uid); 
print ($node_author->field_custom); 
?>

But i have an error :

Recoverable fatal error : Object of class stdClass could not be converted to string

Do you know where I'm wrong? And, is it the best way of proceeding?

Answer 1

Replace the above code with below one:

<?php 
  $node_author = user_load($node->uid); 
  print ($node_author->field_custom); 
?>

Answer 2

You are using print when assigning into a variable, that's you are getting error.

remove print from line 2 and the code should be as below

<?php 
$node_author = user_load($node->uid); 
print render($node_author->field_custom); 
?>

Answer 3

Try with print render($node_author->field_custom);

Or you can try as well:

insert at the top of you node.tpl.php

<?php 
global $user;
$node_author = user_load($user->uid);
$yourvariable = $node_author->field_custom;
?>

Where you want print the field insert:

<?php print $yourvariable['und'][0]['value'];?>

Answer 4

Issue is in the way you are printing the value. actually print is just used for printing string, while print_r is used for printing array or Object. so in your case when you use $node_author->field_custom, then as it is an array, therefore it is not printing and giving you error. You can print it as below.

print_r($node_author->field_custom);

It will print the array, and will not give you error, however if you just want to print the value, then you can print somewhat like:

print $node_author->field_custom[LANGUAGE_NONE][0]['value'];

If above code doesnot work, then paste output of

print_r($node_author->field_custom);

It will give better approach.

//Edited

$image_url = file_create_url($node_author->field_custom[und][0]['uri']);
print render(theme_image($image_url));

Or

print render($node_author->field_custom);
