Changing the integer in a loop

I’m using the Repeater plugin along with FancyBox and can’t figure out how to update the numbers in a loop required to launch the correct lightbox. I’ve searched around and tried various solutions, but none seem to be working for me. Here’s the code I’m working with, the integers that need to be updated in the loop are “various1”, “#inline1”, and “inline1”.

<?php if(get_field('menu_item')): ?>
<?php while(has_sub_field('menu_item')): ?>
<div class="menuBox">
	<div class="menuTop">
		<div class="menuBottom">
		<img src="<?php the_sub_field('food_photo'); ?>" width="161" height="102" alt="" />
			<div class="menuContent">
			<h3><?php the_sub_field('name'); ?></h3>
				<div class="pricePan">
					<div class="price">
					<p><?php the_sub_field('price'); ?></p>
					</div>
					<a id="various1" href="#inline1" class="menuMore">More</a>
					<!-- lightbox starts -->
					<div style="display: none;">
						<div id="inline1>
							<div class="popbox">
								<div class="popupdefaultdiv">
									<div class="popupdescription">
									<h2 class="popupheading"><?php the_sub_field('name'); ?></h2>
									<p class="popupProductDescription"><?php the_sub_field('description'); ?></p>
									<img src="<?php the_sub_field('food_photo'); ?>" width="607" alt="" />
									</div>
								</div>
							</div>
						</div>
					</div>
					<!-- lightbox ends -->
				</div>
			<div class="menuMiddle2">
			<p><?php the_sub_field('description'); ?></p>
		</div>
			<div class="spacer"><!--blank--></div>
		</div>
	</div>
</div>
</div>
<?php endwhile; ?>
<?php endif; ?>

Hi @chrisfry

Sounds like you need to use a counter variable to dynamicaly echo the row number. You can do this like so:

<?php if(get_field('menu_item')): $i = 0; ?>
<?php while(has_sub_field('menu_item')): $i++; ?>
	
	<div id="test-<?php echo $i; ?>">
		
	</div>
	
<?php endwhile; ?>
<?php endif; ?>

Note that the variable $i will increment each row, and you can render it with the echo function.

Does that help?

Cheers
