Wrapping every 3 elements in a loop leaves an empty wrapper

Question

I am wrapping every 3 elements in my loop in a wrapper div like this:

$query = array(
    \'post_type\' => \'post\',
);

$i = 1;

$posts = new WP_Query( $quer         


        

Answer 1

Add the wrapper inside:

$query = array(
    'post_type' => 'post',
);

$i = 1;

$posts = new WP_Query( $query );
$out = '';
$endingNeeded = false;
if ($posts->have_posts()){
    while ($posts->have_posts()){

        if($i % 3 == 1) {
            $out .= '
';
            $endingNeeded = true;
        }

        $posts->the_post();

        $out.= '

            //content here
        
';

        if($i % 3 == 0) {
            $out .= '
';
            $endingNeeded = false;
        }

        $i++;
    }
}

if($endingNeeded) {
    $out .= '
