I am trying to adapt some code I found online and I don't understand one (actually more) of the lines of code.
The code is from a function to generate dropdown lists that depend on previous dropdown lists.
The line says "echo "addOption(document.drop_list.Category, '$nt1[cat_id]', '$nt1[category]');";"
What does the $nt1 mean and why are there two different values for it?
Can someone explain this to me in novice language?
I can't find any reference to addOption in the Javascript reference.
I'm trying to substitute my table fields into the code, but can't figure out which goes where.
