    Is there a more efficient way to increase these numbers? I’ve looked into $i++ but couldn’t make it work.

    <?php $args = array( 'post_type' => 'album' );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();

	$track1 = get_field('track1');
		if($track1 !== '') {
		echo '<br><strong>1 <strong>'; the_field('track1'); } 

	$track2 = get_field('track2');
		if($track2 !== '') {
		echo '<br><strong>2 </strong>'; the_field('track2'); } 

	$track3 = get_field('track3');
		if($track3 !== '') {
		echo '<br><strong>3 </strong>'; the_field('track3'); }
endwhile; ?>

  • What about something close to this (not tested..):

    $i = 1;

while ($i > 0) {
    $track = get_field ('track'.$i);

    if ($track != '') {
        echo '<br><strong>1 <strong>'; the_field ('track'.$i);
        $i++'
    }
    else {
        $i = 0;
    }
}

    There’s more efficient ways to do this, like getting all of the tracks in a function and using a foeraech() loop to go through them, but this is a starting point.

    Thank you Catacaustic!
    This works perfectly. There was a typo at $i++’ and I changed the number inside to $i – exactly what I was looking for.
    You’ve been very helpful, thanks again ??

    while ($i > 0) {
    $track = get_field ('track'.$i);

    if ($track != '') {
        echo '<br><strong>' . $i . ' <strong>'; the_field ('track'.$i);
	$i++;
    }
    else {
        $i = 0;
    }
}
