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

?>

Hi Moonworks,

Are there any records created in that section? And are any of the other fields showing their content from the database?

Let me know. Thanks!

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 [:/]
