Limit Upload Display - Mind Blank!

Hello, All -

I'm sure we must have covered this before - but here we go anyway...

On a List page, how do I limit the number of (image) uploads displayed with each record?

I've just created a Gallery category which features multiple sections spread over many pages. Each page includes a Title, some Content text and about 24 uploaded images.

The galleryList.php is the index from which visitors can access each gallery page. Alongside each link I would like to display a single random thumbnail image (from the corresponding section).

The basic code would be something like this...


<?php

require_once "/xyz/viewer_functions.php";

list($galleryRecords, $galleryMetaData) = getRecords(array(
'tableName' => 'gallery',
));

?>


<?php foreach ($galleryRecords as $record): ?>

<a href="<?php echo $record['_link'] ?>"><?php echo $record['title'] ?></a>


<?php foreach ($record['gallery_images'] as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="" />
<?php endif ?>
<?php endforeach ?>

<?php endforeach; ?>





It seems simple enough but I can't remember how to limit the number of thumbnails. Instead of a single image I get one of every picture in each gallery! The only way I've been able to control this is by inserting a <?php break; ?>[/#ff0000] - but this seems rather clumsy!

Surely there must be a more elegant way of controlling which and how many thumbnails are displayed?

Perch,

The easiest thing I have found to do is to make a seperate "preview image" upload field. This way the user can choose which picture to show as the preview image. Limit this field to a one picture upload and code just this upload field into your list page.

I know this means you have to upload the same picture twice (once as a preview image and once as a gallery image) but it does make it understandable for most users.

As far as making this automatic, I haven't ever tried to code that so I'm not much help there.

Hi perchpole,

If you know all your uploads are images and will have thumbnails you can remove this code:

<?php foreach ($record['gallery_images'] as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="" />
<?php endif ?>
<?php endforeach ?>


Next, if you want to show just one image you can use break like this to stop after just one:

<?php foreach ($record['gallery_images'] as $upload): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="" />
<?php break ?>
<?php endforeach ?>


And if you want a random image you can shuffle your array first:

<?php shuffle($record['gallery_images']) ?>
<?php foreach ($record['gallery_images'] as $upload): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="" />
<?php break ?>
<?php endforeach ?>


Hope that helps!
