Description
this works for me:
<?php $children = nodefamily_relation_load($nid); ?>
<?php
foreach ($children as $childnode) {
print node_view($childnode);this does not, and produces the following warnings:
<?php $children = nodefamily_relation_load_by_type($nid); ?>
<?php
foreach ($children as $childnode) {
print node_view($childnode);warnings:

no you are using the function wrong. have a look at it to see how the array is built or print it yourself by using print_r or dprint_r

@fago - many thanks for the clarification.
by merely replying to my query you are already giving me something, while you really owe me nothing - therefore my appreciation is for granted, no two ways about it.
however, there is an element of sadness in this:
your response assumes that I am a php programmer,
and if I am not, well, pity : I should have been, if I want to use this function.
so, if anybody kind enough finds the time just to tell me what I have to change in the above code to make it work, because I have not got the faintest?
thanks,
abramo

@fago : great : many thanks - this covers me completely :)
strange : this post did not come up when I did a search of past issues - maybe I have to learn to use Drupal search a bit better . . . .
I have a suggestion to make:
perhaps this code example
$children = nodefamily_relation_load_by_type($nid);
if (isset($children['your_content_type'])) {
foreach ($children['your_content_type'] as $childnode)
print node_view($childnode);
}
should go into the README for the module - it would save everybody a lot of unnecessary trouble.
thanks again,
abramo
