I have a form with Value A and B
What i tried to find out was how to :
Entering Value A into a form --> submit the form --> use onBeforeInsert function in myform_edit.php to generate Value B and store this into the table.
So Value B is not entered by the user but generate by ispconfig.
I found that i simply can use $page->dataRecord['B'] = $result['object'] ; to fill B.
