Count total number of post objects

I’m trying to do a count of the total number of post objects selected so that if it’s 1,2 or 3 it shows them in a certain method;

e.g. 1 = full width, 2 = half width etc.

My code is;

<?php 
	if( have_rows('featured_developments') ): 
	$count = 0;
?>          
    <?php while( have_rows('featured_developments') ): the_row(); ?>    
        <?php
            $post_id = get_sub_field('development', false, false);
            $rows = get_sub_field('development');
            if( $post_id ): 	
        	$count++;
        ?>						
			<?php if ($count == 1) { ?>
				1
			<?php } else if ($count == 2 ) { ?>
				2
			<?php } else { ?>
				3
			<?php } ?> 
        <?php endif; ?>      
    <?php endwhile; ?>
<?php endif; ?> 
<?php wp_reset_query(); ?>

However the just outputs 1 2 for some reason, despite only 2 being selected in the back-end.

$count = count(get_field('featured_developments'));
// use this number for the count of rows
if (have_rows('featured_developments')) {
  // etc....
}

Hi John,

Thanks for getting back to me, I tried that and didn’t work the “echo $count = 2” was correct so I used this code;

<?php 
    $count = count( get_sub_field('featured_developments') );
    echo '<strong>The total is '. $count . '</strong></br><br>';
	if( have_rows('featured_developments') == 1 ) {
?>
	<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>			

	<div class="lg-col-12"></div>

	<?php $count++; ?>    
	<?php endwhile; ?>
<?php
	} elseif( have_rows('featured_developments') == 2 ) {
		echo '2';
?>
	<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>			

	<div class="lg-col-6 md-col-6"></div>

	<?php $count++; ?>    
	<?php endwhile; ?>
<?php
	} else{
?>
		<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>			

		<div class="lg-col-4 md-col-4"></div>

		<?php $count++; ?>    
		<?php endwhile; ?>
<?php
	}
?>    
<?php wp_reset_query(); ?>

It outputted “lg-col-12”, when it should’ve outputted “lg-col-6”

In your case there is not a reason to increment count $count++ as $count already has the total number of rows in your repeater.

I removed that thanks, but still no change;

<?php 
    $count = count( get_sub_field('featured_developments') );
    echo '<strong>The total is '. $count . '</strong></br><br>';
	if( have_rows('featured_developments') == 1 ) {
?>
	<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>
		<div class="lg-col-12">
		</div>   
	<?php endwhile; ?>
<?php
	} elseif( have_rows('featured_developments') == 2 ) {
?>
	<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>
		<div class="lg-col-6 md-col-6">
		</div>   
	<?php endwhile; ?>
<?php
	} else{
?>
	<?php while( have_rows('featured_developments') ): the_row(); ?>    
	<?php
	    $post_id = get_sub_field('development', false, false);
	?>
		<div class="lg-col-4 md-col-4">
		</div>  
	<?php endwhile; ?>
<?php
	}
?>    
<?php wp_reset_query(); ?>

$count = count(get_field('featured_developments'));
if (have_rows('featured_developments')) {
	$class = 'lg-col-4 md-col-4';
	if ($count == 1) {
		$class = 'lg-col-12';
	}
	if ($count == 2) {
		$class = 'lg-col-6 md-col-6';
	}
	while (have_rows('featured_developments')) {
		the_row();
		?><div class="<?php echo $class; ?>"><?php echo $class; ?></div><?php 
	}
}

Perfect thanks John, I can see now where I was going wrong 🙂
