I am trying to update a slave grid. Therefore I use $e["on_update"]….
In the update-function I added 'phpgrid_error("Hallo $str");' The output shows nothing but "Hallo " and the SQL-Query.
Using the phpgrid_error in a master table (without slave, the same table as my slave by the way) also shows the data of all the editable fields.
I need this fields for my slave too. What can I do?
