Get last row from a flexible content and display it on another page

I made two pages :
1 – a front page
2 – “basic content page” with a flexible content (rows “selection”) with different text and images.

I use “post object field” in order to get the content from page 2 to page 1.
So now, all the content from the flexible content of the second page are displaying on the front page.
My question is : how could I only display the last row of my flexible content on the first page ?

<?php
$post_object = get_field('relation');

if( $post_object ):
// override $post
$post = $post_object;
setup_postdata( $post );
?>
        <div>
                <?php
// check if the flexible content field has rows of data

if( have_rows('selection') ):
// loop through the rows of data
while ( have_rows('selection') ) :
the_row();

if( get_row_layout() == 'selectionselection' ):
?>
                            <div class="titre-soustitre">
                                <div class="menu-content" data-id="id-<?php  the_sub_field('id'); ?>">
                                    <p class="demo bis"><span class="sub">&nbsp;</span></p>
                                    <a href="#" class="expander"><h1><p class="demo title"><?php  the_sub_field('title'); ?></p></h1></a>              
                                    <p class="demo bis"><span class="sub"><?php  the_sub_field('subhead'); ?></span></p>
                                </div>
                            </div>
                <?php 
endif;
endwhile; else :
// no layouts found
endif;
?>
        </div>
        <?php  wp_reset_postdata();// IMPORTANT - reset the $post object so the rest of the page works correctly  ?>
        <?php  endif; ?>

If I’m understanding you correctly, I would do this:

$post_object = array_reverse(get_field('relation'));

$post_object[0] will now be the last item in that array, so you can then

<div class="titre-soustitre">
    <div class="menu-content" data-id="id-<?php echo $post_object[0]['id']; ?>">
        <p class="demo bis"><span class="sub">&nbsp;</span></p>
        <a href="#" class="expander"><h1><p class="demo title"><?php echo $post_object[0]['title'] ?></p></h1></a>              
        <p class="demo bis"><span class="sub"><?php echo $post_object[0]['subhead']; ?></span></p>
    </div>
</div>

Hi, thanks for your help 🙂
So I did that, but doesn’t seem to work yet.

		  	<?php

			$post_object = array_reverse(get_field('relation'));
			$post_object[0]
			
			$repeater = get_field('repeater', $post_object->id);
					$last_row = end($repeater);
					$last_row['subhead'];

			if( $post_object ): 

			// override $post
			$post = $post_object;
			setup_postdata( $post ); 		

			?>
		    <div>
		    	
                    	
					<?php

					

					// check if the flexible content field has rows of data
					if( have_rows('selection') ):
					// loop through the rows of data
					while ( have_rows('selection') ) : the_row();
					if( get_row_layout() == 'selectionselection' ):?>

						<div class="titre-soustitre">
						    <div class="menu-content" data-id="id-<?php echo $post_object[0]['id']; ?>">
						        <p class="demo bis"><span class="sub">&nbsp;</span></p>
						        <a href="#" class="expander"><h1><p class="demo title"><?php echo $post_object[0]['title'] ?></p></h1></a>              
						        <p class="demo bis"><span class="sub"><?php echo $post_object[0]['subhead']; ?></span></p>
						    </div>
						</div>
						            

				

					<?php endif;
					endwhile;
					else :
					// no layouts found
					endif;

					?>

		    </div>
		    <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
			<?php endif; ?>

I guess I should define the ID on the original flexible content ?
So far, the ID I use on the original flexible content are written by hand through a text field like this data-id="id-<?php the_sub_field('id');?>
Should I change that ?

Hi @simtwo

I believe you can check the total rows by using the count() function and then check if the current row is the last row by using the get_row_index() function. Maybe something like this:

$total_rows = count(get_field( 'selection' ));
// check if the flexible content field has rows of data
if( have_rows('selection') ):

     // loop through the rows of data
    while ( have_rows('selection') ) : the_row();

        if( get_row_index() == $total_rows ) {
            echo "show the last row here";
        }

    endwhile;

else :

    // else

endif;

I hope this helps 🙂
