hi, i m having problems displaying values in a tree menu from the database. I ll try explaining wat i did so that that ll help to solve my problem.
I have two tables in the database one with name 'addcourse' and the other with the name 'subcourse'. what i have to do is compare the values from field name called 'cname' from the addcourse table with the feild name called 'cname from the subcourse table and print the values in the form of a tree menu with the sub course names from a field name called 'subcname'' from the 'subcourse' table. (here the 'cname' values are parent values)
i have tried implementing it but could print the parent values 'cname' but could print only the first values from the 'subcname' table. I am how ever posting the code, help appreciated.
