COUNTING IMAGES IN A MULTI-IMAGE UPLOAD FIELD - Jan 18th, 2012


I needed to count the number of images that existed in a multi-image upload field that was the only record in my editor,
so that if there was only one image I could display it as an image and if there was more than one image I could display
them as a slide show.

I started out with another recipe in the Cookbook called: LIMITING THE NUMBER OF IMAGES ON A PAGE AND SHOWING CODE IF
EXCEEDED (just above this one)

The basic approach in that recipe is:

<?php foreach ($home_page_slidesRecords as $record): ?>
<?php $count = 0; ?>
<?php foreach ($record['image'] as $upload): ?>
<?php $count++; ?>
<?php endforeach; ?>
<?php echo $count>1 ? "There is more than one thumbnail" : "There is only one thumbnail" ; ?>
<?php endforeach; ?>

I modified the code so that instead of messages, the required code was inserted into the page. I also added a checkbox
field to allow the client to decide if they wanted to use this as a slide show regardless of how many images were
uploaded. I also added <?php shuffle($record['images']) ?> to the code to randomize the image displayed when there was
no slide show.

<?php foreach ($home_page_slidesRecords as $record): ?>
<?php $count = 0; ?>
<?php foreach ($record['image'] as $upload): ?>
<?php $count++; ?>
<?php endforeach; ?>
<?php if ($count > 1 && $home_page_slidesRecord['slideshow'] == 1): ?>
<div id="show" class="slideshow"></div>
<?php else: ?>
<?php shuffle($record['images']) ?><?php foreach ($record['image'] as $upload): ?><img src="<?PHP echo
$upload['thumbUrlPath'] ?>" width="<?PHP echo $upload['thumbWidth'] ?>" height="<?PHP echo $upload['thumbHeight']
?>" alt="" />
<?PHP endforeach ?>
<?php endif ?>
<?php endforeach; ?>
