I have a problem with a master/detail setup. When I open a master/detail page the master field value is remembered when I open the standalone detail add page.
An example:
Order > Orderdetails is an master/detail setup. When once I open order 1234 the script remembers this value. When visiting the addpage orderdetailsadd.php directly the script fills in automatically 1234 in the orderfield because it sees that it has an master/detail relationship. Normally this is good. But I want to clear the master value.
Is it possible to clear this master key value in the add page when you just visited a master record. So the order field in the details add page will be blank?
