I've just onto a vps and whenever I try to use the code given in CMS, it doesn't show up, and I get the following error wher an image should be:

Warning: Invalid argument supplied for foreach() in /home/moonworksuk/ackatt/test2.php on line 47

Anybody have any ideas?

Thanks,

joe

Hi Joe,

That error means the variable in the foreach isn't defined. So if you had ...foreach ($record['uploads']... then maybe uploads isn't defined.

Can you attach your viewer file to this thread so we can see the code?

Hope that helps!

Hi Dave,

The code is directly from code generator, nothing added or removed, and nothing else on the page.

<?php

require_once "/home/moonworksuk/ackatt/lib/viewer_functions.php";

list($testRecords, $testMetaData) = getRecords(array(
'tableName' => 'test',
'where' => whereRecordNumberInUrl(1),
'limit' => '1',
));
$testRecord = @$testRecords[0]; // get first record

?>

Adding info would have helped I suppose. My excuse is that it was 4am when I noticed the problem. Maybe I should have checked again before asking [:/]

Is it working now? :) If the problem was that no records were created yet you can also add some code to display a message that says that "No records" instead of the error if it might happen again.

Hope that helps!
