How do I add a class to every nth item in a php loop (wordpress)

Question

I have a Wordpress loop as follows:

 \'portfolio\' ) ); ?>
    have_po         


        

Answer 1

Why not add a counter and use the modulus approach to get to know in every column what element you are currently echoing.

Lets say you have 4 columns as specified.
You start with counter = 1
1 % 4 = 1 ( you are in the first element )
2 % 4 = 2 ( you are in the second element )
3 % 4 = 3 ( you are in the third element )
4 % 4 = 0 ( you are in the fourth element )
5 % 4 = 1 ( you are in the first element )
6 % 4 = 2 ( you are in the second element )

And you just use an If statement with the class as following

 'portfolio' ) ); ?>
    have_posts() ) : $loop->the_post(); ?>
