Reuse layout multiple times on page

Hi there,

I’m using a layout consisting of two textfields and a text area field within a flexible field group.

When I use the above mentioned layout multiple times without adding value to one of the fields, the blank fields are displaying the previous groups records: If I add a title to the first occurrence but leave it blank at the second, the second group will display the title saved at the first.

What am I missing?

<?php
if( have_rows('content') ):
while ( have_rows('content') ) : the_row();
	
	if ( get_row_layout() == 'textblock' ):

		if( get_sub_field('title') ):
			$title =  get_sub_field( 'title' );
		endif;
		if( get_sub_field('lead') ):
			$lead = get_sub_field( 'lead' );
		endif;
		if( get_sub_field('body') ):
			$body = get_sub_field( 'body' );
		endif;
		?>
	
		<section class="textblock">
			<?php echo $title ?>
			<?php echo $lead ?>
			<?php echo $body ?>
	        </section>
    
	<?php
	else :
	endif;
	?>	    
		              	              
<?php
endif;
endwhile;
endif;
?>

This is not an error in the flex field, but in your logic. You are only setting a new value for the 3 variables if the field has a value, but you not resetting or unsetting the previous value it in the next iteration of the loop.

<?php
if( have_rows('content') ):
while ( have_rows('content') ) : the_row();
	
	if ( get_row_layout() == 'textblock' ):

		$title = '';
		if( get_sub_field('title') ):
			$title =  get_sub_field( 'title' );
		endif;
		$lead = '';
		if( get_sub_field('lead') ):
			$lead = get_sub_field( 'lead' );
		endif;
		$body = '';
		if( get_sub_field('body') ):
			$body = get_sub_field( 'body' );
		endif;
		?>
	
		<section class="textblock">
			<?php echo $title ?>
			<?php echo $lead ?>
			<?php echo $body ?>
	        </section>
    
	<?php
	else :
	endif;
	?>	    
		              	              
<?php
endif;
endwhile;
endif;
?>

Thanks for the comment and explanation, it does work as intended.
