Can you please post an example?
Basically, I don't think that post-deleting the objects is good idea.
I do such dynamic stuff using input name prefixes.
Numeric part simply generated by JavaScript.
For example:
input_name_1
input_name_2
...
Each your level can have own prefix, numeric part also should contain
in some form parent number.
For example:
For example:
input_name_1
input_name_1_1
input_name_1_2
...
On server side I know the constraints: starting position and max
depth.
It means that I know the possible numeric parts, so I can do the plain
loop (or few loops) with checking the form structure matches.
for (i=1; ...) {
tmpKey = "input_name_" & i;
if (StructKeyExists(form, tmpKey)) {
// verify and process data
// maybe dive into the inner loop
}
}
Only when I can see valid name, I do something objects manipulations.
Hope this helps.
