Hi (Dave?)-

Trying to display a photo when one exists, and a generic photo when one doesn't exist using the following code:

<?php foreach ($record['photos'] as $upload): ?>
<?php if ($upload['isImage']): ?>
<img src="<?php echo $upload['urlPath'] ?>" width="250px" height="171px" border="0" alt='' /><br/>
<?php else: ?>
<img src="images/photoscomingsoon.jpg" width="250px" height="171px" border="0" alt='' /><br/>
<?php endif ?>
<?php break; //only interestes in 1st photo in loop?>
<?php endforeach ?>

Do you see anything wrong here...It doesn't work...The line after "if" fires correctly and displays a photo when one exists. The line containing "images/photoscomingsoon.jpg" never fires, and I know for a fact there are some records without photos, so shouldn't the "images/photoscomingsoon.jpg" execute?

Thanks for the help...Rick

Hi Rick!

Try something like this:

<?php $upload = @$record['photos'][0] ?>

<?php if ($upload): ?>
show upload
<?php endif ?>

<?php if (!$upload): ?>
show no upload image
<?php endif ?>

Give that a try and let me know how it works. :)

Hi Donna-

Thanks again for the solution. I should have asked yesterday why your solution worked and mine didn't.

Here's yours:

[font "Verdana"]<?php $upload = @$record['photos'][0] ?>
<?php if ($upload): ?>

Here's mine:

[font "Verdana"]<?php foreach ($record['photos'] as $upload): ?>
<?php if ($upload['isImage']): ?>


Does it have something to do with NULL vs. EMPTY values...

Thanks, Rick

Hi Rick,

There is a number of ways to code this up. This is the way I usually do it:

<?php foreach ($gallery['photos'] as $photos): ?>
<?php if ($photos['isImage']): ?>
...insert code here to display image..
<?php endif; ?>
<?php endforeach ?>

<?php if (!$gallery['photos']): ?>
No images available.
<?php endif; ?>

Does that help?
