Count flexible field sub fields

I’m just trying to get a count of this “page_break” layout. There are two being used, and the code returns “1 1”.

I know this is a problem with my counter, but I’ve tried everything and I’ve only managed to create endless loops.

<?php 
  
 // $count = 0;
  
  while( has_sub_field("content") ) : ?> 

    <?php if(get_row_layout() == "page_break") : ?>
		
      <?php echo $count; ?>
      
      <?php endif; ?>
      
      <?php //$count++; ?>
      
<?php endwhile; ?>

You can see how I have my fields set up here:

Actually, if I could count the “break_here” sub field, that would be even better.

Hi @freshyill

Something like the below should work for you:

<?php 
$count = 0;
while( has_sub_field("content") ) : 

    if(get_row_layout() == "page_break") :
	
        if(get_sub_field('break_here')){
           $count++;	
           echo $count;
        }
      
    endif;
      
endwhile; ?>

Hi @FourStacks, this isn’t quite it. This echoes and then increments each one.

So if there are five, the result is this:

12345

but what I’m looking for just 5.

Does that make sense?

Looks like I was just getting the page count in the wrong place. Here’s a working solution.

<?php $pagecount = 0;

while( has_sub_field("content") ) : 
  
  if(get_row_layout() == "page_break") :
  
    if(get_sub_field('break_here')){
      $pagecount++;	
    }
    
  endif;
endwhile;
?>

Then I can just use $pagecount elsewhere:

<?php echo $pagecount; ?>
