[3.34]zs.func.db problems
|
Not sure if it's me or if it's really a problem, but I can't seem to get zs.func.db("database", "key") to work in LUA. For that matter, I had a function that would return the proper value in zscript, but when trying to execute the function in lua using zs.execfunc("funcname", "arguments"), it returned nothing.
Am I missing something?

To use, do:
| Code: |
| #PRINT {@testas("en","Spanish")} |
It'll return nothing. Even when I've actually changed it to: return zs.func.db("languagetable", "en"), it still failed.
So, before I lose my mind, what's not working properly? |

zs.func.db does work. But there are two problems that I can see from what you have provided. First, the first argument to zs.func.db needs to be a variable reference to a database record, not a string with the variable name. To get a CMUD variable reference in lua we must use zs.var.<variablename>. I edited your function to the following:
| Code: |
<func name="testas" language="Lua" id="19">
<value>return zs.func.db(zs.var.reverselanguage, zs.param(1)) .. " : " .. zs.func.db(zs.var.languagetable, zs.param(2))</value>
</func> |
Secondly,
| Code: |
| #PRINT {@testas("en","Spanish")} |
You have your arguments backwards with respect to how the function is written if you're calling it this way. "en" is a VALUE in reverselanguage, "Spanish" is a VALUE in language table. Since these aren't keys zs.func.db still isn't going to return anything. If we make the previous code change and swap the parameters like this:
| Code: |
| #PRINT {@testas("Spanish","en")} |
We'll find it works as expected and we get the following output in CMUD:
As for zs.execfunc I'd have to more about what was going on there. zs.execfunc("funcname", "arguments") is all you should need.
Hope this helps. |

Having the arguments backwards was my mistake on the forums (the code in the actual script I was using was correct, silly me).
Anyway, didn't realize that it had to be zs.var as well. Thanks for pointing that out! |
