Hello-

Can you tell me if you see anything wrong with this code (highlighted in red)...It doesn't want to work...Is this not the way to check for the "non-presence" of a photo? Thanks in advance...Rick[/#008080]

<table border="0" rules="none" cellpadding="0" cellspacing="0" style="position:absolute;left:-5px;top:-18px;width:477px;font-family:arial;font-size:12px;font-weight:normal;">

<?php foreach ($listRows as $record): ?>
<?php
if (($record['status'] != 'Inactive') && ($record['status'] != 'Sold'))
{
//add spacing before photo, only if not on first photo
if ($skipPadding == 2){echo '<tr><td style="font-size:6px;">&nbsp;</td></tr>';}
?>
<tr>
<td width="255px">
<a target="_parent" href="http://www.kellyrealestate.com/<?php echo $record['_link'] ?>">
<?php //echo $record['_link'] //testing ?>

<!--THIS DOESN'T WORK AT ALL - start-->
<!--load this variable in order to test for no main photo-->
<?php //$uploadList = getUploads($options['tableName'], 'main_photo', $record['num']); ?>
<?php //if (empty($uploadList)): ?>
<!--<img src="images/photoscomingsoon.jpg" width="255" height="170" border="0" /><br/>-->
<?php //endif ?>
<!--THIS DOESN'T WORK AT ALL - end-->[/#ff0000]

<?php foreach (getUploads($options['tableName'], 'main_photo', $record['num']) as $upload): ?>
<?php if ($upload['isImage']): ?>
<img src="<?php echo $upload['urlPath'] ?>" width="255" height="170" border="0" /><br/>
<?php //echo $upload['urlPath'] //testing?>
<?php endif ?>
<?php endforeach ?>
</a>
</td>
</tr>

<?php endforeach ?>
</table>

Hi rcrofoot,

How about something like this instead? (changes in red)

<?php $noImagesFound = true; ?>
<?php foreach (getUploads($options['tableName'], 'main_photo', $record['num']) as $upload): ?>
<?php if ($upload['isImage']): ?>
<?php $noImagesFound = false; ?>
<img src="<?php echo $upload['urlPath'] ?>" width="255" height="170" border="0" /><br/>
<?php //echo $upload['urlPath'] //testing?>
<?php endif ?>
<?php endforeach ?>

<?php if ($noImagesFound): ?>
<img src="images/photoscomingsoon.jpg" width="255" height="170" border="0" /><br/>
<?php endif ?>

That would also catch the case when a record has uploads but none of them are images.

I hope this helps, please let me know if you have any questions.
All the best,
Chris

Thanks Chris...Actually what you suggested, is what I already had...But there is a more efficient way to do it...I know the syntax from a former version of cmsBuilder, but I'm trying to implement it in a newer version...Here's what I mean:

In cmsBuilder version v1.09:[/#ff0000]

<?php
$listing_agent=$record['listing_agent'];
require_once "/usr/www/users/decaro/kellyassociates/decaro/cmsAdmin/lib/viewer_functions.php";

$options2 = array(); // NOTE: see online documentation for more details on these options
$options2['tableName'] = 'agents_ka'; // (REQUIRED) MySQL tablename to list record from. Example: "article";
$options2['recordNum'] = ''; // (optional) Record number to display. Example: "1"; Defaults to number on end of url, then 1
$options2['where'] = "full_name='".$listing_agent."'"; // (ADVANCED) MySQL WHERE conditions to use INSTEAD of recordNum to look up record. Example: "fieldname = 'value'"
$record2 = getRecord($options2);
//echo $record2['email'];
?>

<!--load this variable in order to test for no main photo-->
<?php $uploadList = getUploads($options['tableName'], 'main_photo', $record['num']); ?>
<?php if (empty($uploadList)): ?> [/#0080ff](this works in older version)
[/#000000] <img id="mainPix" src="images/photoscomingsoon_450_300.jpg" width="600" height="400" border="0" /><br/>
<?php endif ?>

Now, in v1.33 I'm working with this:[/#ff0080]

<?php

require_once "/usr/www/users/decaroii/cmsAdmin/lib/viewer_functions.php";

list($agentsRecords, $agentsMetaData) = getRecords(array(
'tableName' => 'agents',
'orderBy' => 'lastname ASC',
));
?>

<?php foreach ($agentsRecords as $record): ?>
<?php if (empty($record['agent_image_big']) && $record['bio']=='')
{ ?>
<a href="#" onclick="javascript:alert('<?php echo $record['agent_name'] ?>\'s homepage is currently under construction...');"><?php echo $record['agent_name'] ?></a><br>
[/#008000] <?php
}else if($record['bio']=='').......etc, etc, etc......end foreach loop...

The code in green above works, but I don't think it's reliable...

Doug had sent me the code for v1.09

<?php $uploadList = getUploads($options['tableName'], 'main_photo', $record['num']); ?>
<?php if (empty($uploadList)): ?>

but I can't get that code to work in 1.33 (changed $options['tableName'] to a few different variations, and substituted the new field in place of 'main_photo' but with no luck)...

Anyway hope that's somewhat clear...Any ideas...

Thanks, Rick

Hi Rick,

I think getUploads() is only necessary if you getRecord() (i.e. load a single record.) The preferred method is to use getRecords() (i.e. load zero or more records) which, by default, will load all uploads.

It looks perfectly sane to me. What makes you think it's unreliable?
All the best,
Chris
