setName for children

[EssickAir]

So I'm trying to use setName as a way to change the name of about 1000 child pages because I need it to be different. I wrote the code an it works because it is changing the URL but not the "name" of the page. What am I doing wrong?
 

<?php
foreach($page->children() as $child){
	$sku = str_replace(' ', '-', strtolower($child->upc));
	$page->setName($sku);
}
?>

What am I doing wrong? the UPC changes. but the page name does not.

 

Thanks

Do you save the page after changing its name?

OMG you're a genius. I don't know how I missed that, but thanks. I just needed to run $child->save(); 

thanks
