Can anyone explain how this can work on my detail page, thank you!
<?php if(isset($_GET['buc_id'])) { ?>
<!-- This should be the first entry, preferably in alphabetical order -->
<a class="btn btn-outline-secondary btn-sm" href="bucketinfo.php?buc_id=<?php echo($_GET['buc_id'] = 1);?>" role="button"><<</a>
<!-- This should be the previous entry, preferably in alphabetical order -->
<a class="btn btn-outline-secondary btn-sm" href="bucketinfo.php?buc_id=<?php echo($_GET['buc_id'] - 1);?>" role="button"><</a>
<!-- This should be the next entry, preferably in alphabetical order -->
<a class="btn btn-outline-secondary btn-sm" href="bucketinfo.php?buc_id=<?php echo($_GET['buc_id'] + 1);?>" role="button">></a>
<!-- This should be the last entry, preferably in alphabetical order -->
<a class="btn btn-outline-secondary btn-sm" href="bucketinfo.php?buc_id=<?php echo($_GET['buc_id'] ?? );?>" role="button">></a>
<?php } ?>
