I want to retrieve all the repeater rows that contain a specific subfield. I have a variable date field defined as follows :
$journey_value = $_GET['onward-date'] != '' ? $_GET['onward-date'] : '';

The “event_bus_date” is also a date field and both $journey_value and event_bus_date are in same date format.I have the following code but it displays nothing :

<?php if( have_rows('event_instance') ): ?>
            <ul>
              <?php while( have_rows('event_instance') ): the_row(); ?>
			    <?php if($journey_date == the_sub_field('event_bus_date')) { ?>
                 <li><?php the_sub_field('event_bus_date'); ?></li>
			    <?php } ?>
              <?php endwhile; ?>
            </ul>
          <?php endif; ?>

Please help to find the error in the code! Thank you

the_field() and the_sub_field() are only used to output the value on the page and they do not return the value.

use get_field() or get_sub_field()

<?php if($journey_date == get_sub_field('event_bus_date')) { ?>
