[solved] Count # of PDFs in field and echo

[louisstephens]

So maybe has already figured this out, but I am stumped. I have a field (test_field) that is set to pdfs, and I was trying to get a count of the number of pdfs in that field so I could add it to a status bubble on the front end. I tried:

function testPDF() {
	$a = $page->test_field->count();
	echo "<span class=\"bubble\">" . $a . "</span>";
}

but it is returning "NULL" . I currently have 3 added to the field. I also tried putting this function in _func.php, though I need to use wire('pages'), but I only need to get the count for that specific page, so I am sort of at a loss of how to proceed.

How do you access $page inside a function closure? You can't. Use wire()->page or wirePage() or page() or wire('page')

Yep, I completely forgot about using wire('page') in the _func.php . That did the trick. Thank you abdus.

You have multiple options like :

function a() use($page) {
	count($page->field);
	// or
	$page->field->count();
}
// If you call field from different page, this one is useful
function b($page = null) {
	$page = is_null($page) ? wire('page') : $page;
	count($page->field);
	// or
	$page->field->count();
}
// If your using ProcessWire 3 and $config->useFunctionsAPI = true;
function c() {
	count(page()->field);
	// or
	page()->field->count();
}
// etc...
