I’m using $child->ID on 2.8.x myself. I’ll look into it for you 😉
$child->ID seems to work fine in 2.9-RC1. Maybe it has something to do with how you use the $childID array after that block?

Thank you for your help. In 2.8.6, $child->ID gives me a number. In 2.9, $child->ID gives me NULL. And $child itself gives me the same number as 2.8.6 did for $child->ID.
I didn’t test RC1.
That’s pretty bizarre. And I can tell you just by looking at the diff, get_children() itself has not changed in 2.9 final.

$p = get_page($child);
That line doesn’t make any sense to me. I’m pretty sure that’s causing the problem.

Thank you very much for this. I’ll sit down and try and rewrite this “properly”.
You’re welcome! (And I got the chance to test more of my future upgrades)

For the record, here is the final working (both 2.8.x and 2.9) version:
function children_title2id() {
$children = get_children("post_type=page&post_parent=" . get_the_ID());
foreach ($children as $child) {
$t = strtolower($child->post_title);
// Title points at pageID
$childID[$t] = $child->ID;
};
return $childID;
};
The missing post_type=page that miqrogroove earlier picked up on is required according to the Codex. But it is the $p = get_page($child); that was really killing it.
It creates an array where the keys are the page titles in lower-case. And the associated value for each key is the page ID for the page.
