Extra class in last of while loop?

[wyclef]

Hey, using advanced custom fields for wordpress which has a repeater field function as follows. i'm interested in a way to add a special class to the last P tag in the array. Not sure how.

<?php while(the_repeater_field('test')): ?> 
<p><?php the_sub_field('test-sub'); ?></p> 
<?php endwhile; ?>

This solution may seem a bit long-winded following the 3 lines of code above, but it is only because WordPress' functions offer little control for honest developers and seem to cater more toward designers.

This is untested, but it should work as desired:

<?php

$sub_fields = array();

// Capture the output from `the_sub_field()` to an array
while ( the_repeater_field( 'test' ) )
{
    ob_start();
    the_sub_field( 'test-sub' );
    $sub_fields[] = ob_get_clean();
}

?>

<?php while ( $sub_field = array_shift( $sub_fields ) ): ?>
    <?php echo empty( $sub_fields ) ? '<p class="last-item">' : '<p>'; ?>
        <?php echo $sub_field; ?>
    </p>
<?php endwhile; ?>

thanks a lot. this does work. it does seem a bit much but wordpress is a pita so...

what if you were to have different the_sub_field( 'test-sub' ); within the same while loop? like the_sub_field( 'test-sub' ); and the_sub_field( 'test-test' ); and the_sub_field( 'test-pro' );

Care to elaborate? I'm definitely no WP guru... not sure where you're headed with that one.

trying to do something with more fields in the loop like follows

<?php

        $sub_fields = array();
        
        // Capture the output from `the_sub_field()` to an array
        while ( the_repeater_field( 'test' ) )
        {
            ob_start();
            the_sub_field( 'test-sub' );
            $sub_fields[] = ob_get_clean();
        }
        
        ?>
        
        <?php while ( $sub_field = array_shift( $sub_fields ) ): ?>
            <?php echo empty( $sub_fields ) ? '<p class="last-item">' : '<p>'; ?>
                <?php echo $sub_field; ?>
            </p>
            <span><?php the_sub_field('test-sub-new'); ?></span>
            <a href="<?php the_sub_field('test-sub-link'); ?>"></a>

        <?php endwhile; ?>
