This is very popular situation! The HTML example with checkboxes array:
<form method=post action=''>";
<input type=checkbox name=box value='John'>
<input type=checkbox name=box value='Mike'>
<input type=checkbox name=box value='Rone'>
Param "box" is array.
As example, a simple HTTP GET request:
/?a=first&a=second&b=1&b=2
In this request we can see 2 two-elements arrays:
a=first, a=second
b=1, b=2
or 2 rows:
a=first, b=1
a=second, b=2
Problems:
1. When names and number of the array elements are not known we can't
use ns_querygetall
2. When some items can be not defined is needed the additional check
of arrays elements count. As example
/?a=first&a=second&b=1&a=third&b=3
But
[ns_querygetall a] {first second third}
[ns_querygetall b] {1 3}
Of course, these are _not_ the 3 rows becouse value [lindex
[ns_querygetall b] 2] = "" is invalid!
