[SOLVED] Check string's length

[Rudy]

Hey guys,

What's the problem with this?

if string.len(guiGetText(varible)) == 0 then 
    --something 
end 

I think nothing, but it isn't works. I tested the guiGetText function with this varible, and it's works. Zero errors printed to my server's log.

Thanks,

Rudy

What does debugscript (/debugscript 3) say?

I don't see any problems, as long as 'variable' is assigned to a GUI element.

I tested the guiGetText function with this varible, and it's works. Zero errors.

It isn't that important, because this is only a comfort function - but it'd be good if somebody write down what is the problem. Lines before and after this code are work too.

And you're sure the string is completely empty? Is the GUI element properly created? If that if statement fails to run it could mean that guiGetText returns false - or nil. But if that was the case, it should output it in the debug. Make sure you check the debug for any errors.

Yes, If it's empty returns false. I tested it first. And I write down again: errors do NOT exist. But I reinstalled all MTA server files, and the problem's solved.

If the string is empty it should return 0 as far as I'm aware, and not false. It would only return false if the GUI element does not exist or it received something other than a string.
