Hi all,
I just had a bit of work to do with Zend_Paginator (nb. with
Zend_Db_Table_Select) and I noticed some weird behaviour. Let's take
this simple code as an example:
$paginator = Zend_Paginator::factory($table->select()->where('foo is null'));
$paginator->setCurrentPageNumber(1);
If the query returns more than default number of rows in Paginator
(10) then I get Iterator with 10 first elements and that's quite all
right.
Now, imagine that query returns 100 rows (which makes 10 pages in
default configuration). User requests page number 20:
$paginator->setCurrentPageNumber(20);
As a result I get 10 *last* rows (exactly the same when requesting
10th page). My expectation is to get empty Iterator, because page
number 20 does not exists.
I dig into the code and I found, that's because of
normalizePageNumber() method which changes my requested 20 into 10.
Is that behaviour really helpful? I think it should be parametrized
because sometimes (i.e. in my case - fetching next pages while
scrolling the page down) it completely distorts the effect - at the
end I get last page every time I request the next one.
What do you think?
Regards,
Bartosz
