Many Elements have both a "default" option and an "eval" option.
When you turn on "eval", the text entered in the "default" option is treated as PHP.
The PHP expression is evaluated and the data 'returned' is used as the element's default value.
PHP:
return 'a string';
Using placeholders....
PHP:
return '{tablename___elementname}';
Get a filter value
PHP:
return FabrikHelperElement::filterValue(81); //81 is the id of the filter element
Insert a URL parameter (e.g. to set the default of a non-writable element, which can't be set for security reasons directly via URL)
PHP:
$myInput = JFactory::getApplication()->input;
$myParam = $myInput->get('urlparam','');
return $myParam;
