getTotal() is "undefined"

[Valery]

Hello, everybody,

I am trying to display the number of published articles per author.

echo $wire->pages->find("author~=Sam Smith").getTotal();

PW says: Error Call to undefined function getTotal()

However, the function is in the Cheatsheet. 

And second: why does 

echo $wire->pages->find("author~=Sam Smith").count();

give me "1001|1002" instead of the number of found pages? What's the correct way to count a PageArray size?

Thanks for any help with that.

->getTotal() not .getTotal().

Thanks, Soma. My bad, sorry.

Everything's working now.

echo $wire->pages->find("author~=Sam Smith")

Doing echo on a page array, this will output id's separated with a pipe. This is using a toString method that is for convenience if you use the result in a other selector it will get inserted as string as 1929|1293|1231. Which is handy. Otherwise it will be a page array you can further use.

For example:

$found = $wire->pages->find("somefield*=anyword");
$result = $wire->pages->find("selected_authors=$found");

Which will result behind the scenes as something like this:

$result = $wire->pages->find("selected_authors=1928|1233|1234");

Where selected_pages would be a page field for example.

If you just really need the count of a find you can also just use count instead.

$count = $pages->count("authors*=John");

Which is more efficient than a find.

Thanks for the insight. Really appreciate your help with finding and counting vs just counting. Handy!

Definitely use the $pages->count() as Soma mentioned. If you are dealing with a large quantity of pages, and all you need is the count, it is much faster, since it doesn't have to load those pages.

Didn't know that was possible Soma... tnx
