Loop helpers function

[sebastian.pisula]

while(have_post()) {
the_post();

if(is_loop_first()){
echo 'first';
}

if(is_loop_index(5)){
echo 'is 5 index element';
}

if(is_loop_last()){
echo 'last';
}

}

In the past I've had the need to determine first/last/odd/even posts in the loop.

I think these functions need better names, and we'll need to decide whether first/last means the first/last in the current loop or the first/last in the current loop's query. Might be worth taking a look at some theme frameworks to see if there's prior art.

These will of course need unit tests.

33860.diff​ adds three helper functions: query_post_index(), query_is_first_post() and query_is_last_post(). Including tests.

Getting the first and last post is usually needed more often, as odd/even queries are usually used for styling only (which you can target with CSS). If you want to detect the odd/even post, you can create your own helper function leveraging query_post_index().

33860.2.diff​ is an updated patch after the recent changes to the factory properties.

I'm not convinced we really need these. It doesn't feel like we're gaining a lot by them for the cost of having to maintain them going forward.

It's easy to implement this on your own if you wish, but I think for now this is not something we should do.

I think that this is good idea to add this to core. This is interesting helper

[obenland]

I feel like it being a good idea, or interesting, is still not a good enough reason to add these.

The original proposition hasn't changed since this ticket was closed. There should be a Core need to adopt these functions, which is currently not there.
