Arrays

I've had a look at this URL: http://www.wowinterface.com/forums/s...t=table.insert and the LUA documentation but still can't seem to find a solution for my problem:
I can't insert data into a array that looks like this:

Code:

arrayName = {
    {
        nick="nick 1",
        name="name 1",
        age="age 1",
    },
    {
        nick="nick 2",
        name="name 2",
        age="age 2",
    },
};

If I manually set the array to look like above I can fetch the data with this code:

Code:

nick = arrayName[i].nick);
name = arrayName[i].name);
age = arrayName[i].age);

I've tested the following:

Code:

arrayName = {}

table.insert(arrayName.i.nick, nick);
table.insert(arrayName.i.name, name);
table.insert(arrayName.i.age, age);

And this:

Code:

arrayName = {}

table.insert(arrayName[i].nick, nick);
table.insert(arrayName[i].name, name);
table.insert(arrayName[i].age, age);

This:

Code:

arrayName = {}

table.insert(arrayName[i]."nick", nick);
table.insert(arrayName[i]."name", name);
table.insert(arrayName[i]."age", age);

... and this:

Code:

arrayName = {}

table.insert(arrayName[i]["nick"], nick);
table.insert(arrayName[i]["name"], name);
table.insert(arrayName[i]["age"], age);

I believe the problem is you're not adding [i] in. Try this:

Code:

arrayName = {
   [1]= {
        ["nick"]="nick 1",
        ["name"]="name 1",
        ["age"]="age 1",
    },
    [2]={
        ["nick"]="nick 2",
        ["name"]="name 2",
        ["age"]="age 2",
    },
};

It might be a bit excessive, but it works and is easy to read (IMO)
Then you can access it like this:

Code:

nick = arrayName.[i].nick
name = arrayName.[i].name
age = array[i].age

If you're still confused, take a look at http://www.lua.org/pil/3.6.html

        ["nick"]="nick 2",
        ["name"]="name 2",
        ["age"]="age 2",
    },
};

I've thought about this too. I'll have a look at it then. I hope I don't run into the same problem again; that I can't insert the data... Then I'll get back to you :- ).

Then you can access it like this:

Code:

nick = arrayName.[i].nick
name = arrayName.[i].name
age = array[i].age

Aye, I see.

Thanks for the link :- )

Try something like this:

Code:

temp = {
        nick="nick n",
        name="name n",
        age="age n",
    }

table.insert(arrayName, temp);

EDIT: And another thing, in LUA is called table, not array.

I made it myself, but thanks either way.
