7,424 PointsGeneral PHP question about the elements in this loop.
Hi!
I'm forgetting something basic, and I'm having trouble tracking down the specific answer.
In this beginning section of a loop:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
Why are the empty parentheses necessary? Is this where an argument would go?
Thanks :)
