Question

I have a simple foreach loop like:

foreach ( $posts as $index => $posts )

and also a counter:

if( $index % 5 + 1 == 5 ) {
//do something 
}

I have 15 posts per page and it should do something every fifth item but NOT on the last but how do I do that?

So it becomes:

POST
POST
POST
POST
POST
DO SOMETHING
POST
POST
POST
POST
POST
DO SOMETHING
POST
POST
POST
POST
POST

Answer 1

If you know, you have 15 posts, and need every 5th but not the last…
That means you need to ‘make something’ with the 5th and 10th one, am i right?
So why not check that?

if($index == 4 || $index == 9)
