Exclude pages from PageField (front-end)

[a-ok]

Apologies if this has been answered before. I have a simple PageField set up, and on the front-end I'm wanting to split the pages selected into two variables; primary and secondary. I thought this would work but doesn't?

$primary_tags = $article->article_tags->not("id=1336|1337|1338|1339|1327|1326|1328");
$secondary_tags = $article->article_tags->not("id=1042|1043|1044|1340|1341");

This is within the loop so $primary_tags should be returning all the pages selected via the PageField EXCEPT the ones listed, and the same goes for $secondary_tags.

Any thoughts? Am I missing something?

not() modifies the original PageArray, so you need to populate your variables with a copy of the original PageArray before you filter them.

($primary_tags = $article->article_tags->slice(0))->not("id=1336|1337|1338|1339|1327|1326|1328");
($secondary_tags = $article->article_tags->slice(0))->not("id=1042|1043|1044|1340|1341");

This is great, thanks BitPoet. I'm unsure why I didn't think to slice it... so slicing it would effectively create a new instance of the PageArray?

find() would also work here:

$primary_tags = $article->article_tags->find("id!=1336|1337|1338|1339|1327|1326|1328");
$secondary_tags = $article->article_tags->find("id!=1042|1043|1044|1340|1341");
