Unique ID's for each layout row

Hi, i’m just experimenting with Flexible Fields and wonder if this is possible?

I’m using the demo code from here: http://www.advancedcustomfields.com/resources/field-types/flexible-content/

<?php 
 
/*
*  Loop through a Flexible Content field and display it's content with different views for different layouts
*/
 
while(has_sub_field("content")): ?>
 
	<?php if(get_row_layout() == "paragraph"): // layout: Content ?>
 
		<div>
			<?php the_sub_field("content"); ?>
		</div>
 
	<?php elseif(get_row_layout() == "file"): // layout: File ?>
 
		<div>
			<a href="<?php the_sub_field("file"); ?>" ><?php the_sub_field("name"); ?></a>
		</div>
 
	<?php elseif(get_row_layout() == "featured_posts"): // layout: Featured Posts ?>
 
		<div>
			<h2><?php the_sub_field("title"); ?></h2>
			<?php the_sub_field("content"); ?>
 
			<?php if(get_sub_field("posts")): ?>
				<ul>
				<?php foreach(get_sub_field("posts") as $p): ?>
					<li><a href="<?php echo get_permalink($p->ID); ?>"><?php echo get_the_title($p->ID); ?></a></li>
				<?php endforeach; ?>
				</ul>
			<?php endif; ?>
 
		</div>
 
	<?php endif; ?>
 
<?php endwhile; ?>

Say when administering the site then, i enter content such as:

• Paragraph
• File
• Paragraph
• Featured Posts
• File
• Featured Posts
• Paragraph

How would i output a unique number attached to each instance of a layout? ie

• Paragraph (1st instance of paragraph)
• File (1st instance of file)
• Paragraph (2nd instance of paragraph)
• Featured Posts (1st instance of featured posts)
• File (2nd instance of file)
• Featured Posts (2nd instance of featured posts)
• Paragraph (3rd instance of paragraph)

If that’s not possible is there a way to increment each layout instance with a unique number like this instead? ie

• Paragraph (1st layout)
• File (2nd layout)
• Paragraph (3rd layout)
• Featured Posts (4th layout)
• File (5th layout)
• Featured Posts (6th layout)
• Paragraph (7th layout)

Hope that makes sense! Thanks in advance 🙂

Hi @kurdt_the_goat

Both of these outputs are possible with PHP. Please see below for the first example:

<?php 
 
/*
*  Loop through a Flexible Content field and display it's content with different views for different layouts
*/

$counters = array();
 
while(has_sub_field("content")): 

	
	// update counter
	$layout = get_row_layout();
	
	if( !isset( $counters[ $layout ] ) )
	{
		// initialize counter
		$counters[ $layout ] = 1;
	}
	else
	{
		// increase existing counter
		$counters[ $layout ]++
	}

	?>
 	
 	<p><?php echo $layout; ?> instance #<?php echo $counters[ $layout ]; ?></p>
 	
	<?php if(get_row_layout() == "paragraph"): // layout: Content ?>
 
		<div>
			<?php the_sub_field("content"); ?>
		</div>
 
	<?php elseif(get_row_layout() == "file"): // layout: File ?>
 
		<div>
			<a href="<?php the_sub_field("file"); ?>" ><?php the_sub_field("name"); ?></a>
		</div>
 
	<?php elseif(get_row_layout() == "featured_posts"): // layout: Featured Posts ?>
 
		<div>
			<h2><?php the_sub_field("title"); ?></h2>
			<?php the_sub_field("content"); ?>
 
			<?php if(get_sub_field("posts")): ?>
				<ul>
				<?php foreach(get_sub_field("posts") as $p): ?>
					<li><a href="<?php echo get_permalink($p->ID); ?>"><?php echo get_the_title($p->ID); ?></a></li>
				<?php endforeach; ?>
				</ul>
			<?php endif; ?>
 
		</div>
 
	<?php endif; ?>
 
<?php endwhile; ?>
