Get only the matching subfield value within the repeater element inside a code b

Hello!
I have set up an Oxygen Repeater elment. I know need to create a bit of php code to get a subfield of the repeater in a specific way. I have tried this with the following code:

<?php if( have_rows('veranstaltung_treffpunkt') ): ?>

    <?php while( have_rows('veranstaltung_treffpunkt') ): the_row(); ?>

        <?php 

        // vars
        $value = get_sub_field('what3words');
        $str2 = ltrim($value, '/');
        ?>

<a href="https://w3w.co/<?php echo $str2; ?>">/// <?php echo $str2; ?></a>

    <?php endwhile; ?>

<?php endif; ?>

The problmen now is, that all the sub field values are shown underneath each repeated element. Kinda creating a loop inside a loop.
Is there a way, to just call the specific subfield value of the specific row, which is generated from the oxygen repeater element? So that I can use the code-block within the repeated element?

Thanks very much for your help 🙂

Only if you can pass that value to the PHP code. I don’t know anything about the builder you’re using so I can’t answer that.

Normally in php I would do something like this to only show a specific row.

<?php if( have_rows('veranstaltung_treffpunkt') ): ?>

    <?php while( have_rows('veranstaltung_treffpunkt') ): the_row(); ?>

        <?php 

if (get_sub_field('some-field') == $passed_value)) {
        // vars
        $value = get_sub_field('what3words');
        $str2 = ltrim($value, '/');
}
        ?>

<a>">/// <?php echo $str2; ?></a>

    <?php endwhile; reset_rows(); ?>

<?php endif; ?>

Hello! Thanks again! Sometimes the easy approach actually works.

<?php 
        // vars
        $value = get_sub_field('what3words');
        $str2 = ltrim($value, '/');
?>

<a href="https://w3w.co/<?php echo $str2; ?>">/// <?php echo $str2; ?></a>
