I'm sure there is an easy fix to this, but I was not able to find anything in the PHP Manual or other places I searched.

On one of my pages I am testing to see if there are any photos in the uploads for the section.  If there are, it displays their thumbnails.  If not, it just does not show anything. Below is the code that I'm using.  It works fine on PHP 7.4, but if I switch to 8, it throws an error and nothing on the page after the error will display.

The culprit seems to be the :None in the first If statement.  Works fine in 7.4, but not 8.  I've tried using the empty() or isset() functions, but I'm not doing something right.

                                <div class="photo-gallery">
                                    <div class="row photos" style="padding-bottom: 20px;">
                                        <?php if (!$record['photos']):None ?>
                                        <?php else: ?>
                                            <?php foreach ($record['photos'] as $index => $upload): ?>
                                                <?php if ($index >= 4) { continue; } // limit uploads shown ?>
                                                <div class="col-sm-6 col-md-4 col-lg-3 item">
                                                    <a href="<?php echo htmlencode($upload['urlPath']) ?>" data-lightbox="photos<?php echo htmlencode($record['num']) ?>"><img class="img-fluid" src="<?php echo htmlencode($upload['urlPath']) ?>"/></a>
                                                </div>                                                 
                                            <?php endforeach ?>
                                        <?php endif ?> 
                                    </div>
                                </div>

Thanks in advance for any help...

Jerry,

I just tried deleting the None and that breaks the whole page.  Just get a blank page when loading.

I can give the elseif a try a bit later and see if that works.  I'm not sure it will work since I have to test the first if to see if there are any photos (uploads) for that record.  That is what the None is doing now.

There's both a ! and a None in that line I'm not sure, but that seems to be a double negative.

Try reversing the logic. IE if records then show records, else if !records leave it blank

                                <div class="photo-gallery">
                                    <div class="row photos" style="padding-bottom: 20px;">
                                        <?php if ($record['photos']):?>
<?php foreach ($record['photos'] as $index => $upload): ?>
                                                <?php if ($index >= 4) { continue; } // limit uploads shown ?>
                                                <div class="col-sm-6 col-md-4 col-lg-3 item">
                                                    <a href="<?php echo htmlencode($upload['urlPath']) ?>" data-lightbox="photos<?php echo htmlencode($record['num']) ?>"><img class="img-fluid" src="<?php echo htmlencode($upload['urlPath']) ?>"/></a>
                                                </div>                                                 
                                            <?php endforeach ?>
                                       <?php elseif (!$record['photos']):?>&nbsp;                                            
                                        <?php endif ?> 
                                    </div>
                                </div>

When I deleted the None previously, I also deleted the : which is what broke the page.  Keeping the : at the end of the IF statement and removing the None works on PHP 7.4 and 8.

Thanks for the suggestions.
