I made a table hobby, in that i took an array named hid[].
In that i passed hid and hnm.
I have another table employee and I take hid as an foreign key.
When I passes the hid from front end as :
hid :
[0] -> 1
[1] -> 2
[2] -> 3
When I passes the hnm from front end as :
[0] -> Reading
[1] -> Swimming
[2] -> Dancing

Can anyone help me to resolve this issue ?

What is hid?
deeeeeeeep 4-Dec-18 2:28am
   
hid is a primary key of table hobby.
Also hid is a reference key of table employee.
Mohibur Rashid 4-Dec-18 3:36am
   
You have dumped lots of code, help won't come easy, you also need to specify where your hid is returning empty
