I’m not completely sure what you’re trying to do, so I’m assuming some things.
<?php
$count = 0; // keep track of how many posts were shown
// the standard WP loop
if (have_posts()) {
while(have_psits()) {
the_post();
$count++; increment count
if ($count == 1) {
// showing first post
// code here to show fields A & B
} else {
// showing older posts
// code here to show fields x & y
}
}
}
?>
