I want to display PHP variable from the database in the description of an inputfield. With your documentation, i was able to display the value as default in the inputfield. How can I do this for the description-field?

Many thanks, great component!

I found a solution. Make a placeholder {description} for the descriptionfield. Go to "Script called on form display". There put your DB-Query, attache it to the global variable $formLayout. With the str_replace function you can change the value of the placeholder.

$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select($db->quoteName(array('Column1', 'Column2')));
$query->from($db->quoteName('yourtable'));
$db->setQuery($query);
$row = $db->loadRowList();

$formLayout = str_replace('{description}', $row ,$formLayout);

You can also use it for the global variable $adminEmail, go to "Script called before the Admin Email is sent".
$adminEmail = str_replace('{description}', $row ,$adminEmail);
