$page->matches and $pages->find inconsistency

[Zeka]

Hi.

I can't figurate out is it a bug or I miss something 

$selector = '(template=catalog_category|product), (id=1430|1530|1443|1528|1442|1441|1440|1527|1529|1439|1438|1437|1436|1531|1523|1522|1435|1433|1434)';
$some_pages = $pages->find($selector);
$some_pages->has('id=1417') // true

Then on the page with ID 1417

$page->matches($selector) // false

As you can see that the page with ID 1417 is found by the selector, but do not match it.

OR-Groups are not supported by the in-memory matcher.

@LostKobrakai It's not the first time when I met that something works with memory and not DB. Maybe the dumb question, but is there some way to determine it? (I guess the answer will be like - read source code ? ).

It's in the selectors docs (admittedly, in the fine print at the bottom of the relevant section):

Please note: OR-groups work with database-driven find operations, but not with in-memory filtering (where they are less useful). OR-groups also require ProcessWire 2.5 or newer.

@Zeka There is many inconsistencies between in-memory and DB. Things being case sensitive etc. I'm recently seeing the inconsistency throw people more and more. As the API is the same - I think it's hard to know what's going to be DB and what's going to be in-memory.

I think there are things that can be done to bring in-memory searches to bring it inline with DB searches. 

For now this should work:

<?php
	$validation = [];
	preg_match_all('/\(([^\)]+)\)/' $selector, $matches);
	foreach($matches[1] as $match) {	
		$validation[] = $page->matches($match);
	}
	if(in_array(true, $validation)) {
		// Page Matches one OR Group.
	}
?>

I haven't tested it, but it should work, might require a little tweaking. 

Or

<?php
	$validation = false;
	preg_match_all('/\(([^\)]+)\)/' $selector, $matches);
	foreach($matches[1] as $match) {
		if(!$validation) {
			$validation = $page->matches($match);
		}
	}
	if($validation) {
		// Page Matches one OR Group.
	}
?>
