There are multiple identical data entries on the same page, divided into groups.

Now I have a problem.
I cannot obtain the name sequence automatically generated by smaryt for input.
The indexes 0 and 1 are generated by smarty through variables.





I cannot get these values for $ _ POST now. why?
Var_dump ($ _ POST [my]);

Array (size = 2)
0 => string 'array'
1 => string Array'

Please help.

------ Solution --------------------
Bored, right?
Since you
Var_dump ($ _ POST [my]);
Display
Array (size = 2)
0 => string 'array'
1 => string Array'

So
Print_r ($ _ POST ['my']);
Why is there nothing?
