Parameters passed in the function are confusing

4 posts in this topic

Hi All,

I am using a function

Func Verify($a, $b, $c, $link = 1, $Time = 60)

Endfunc

I want to know are these parameters

$link = 1, $Time = 60

are optional.

if yes

then when i call this function somewhere i got error incorrect no of parameters passed

And if i pass the value only for $link = 1 then it works .

i have question that why is it working as i have not called the parameter $Time

 is it necessary to declare them in " " to make them optional. ?

The last 2 parameters in that function are optional, you have to pass it the first 3, but not the last 2. You can call the function using the $link parameter if you needed to, but you don't have to. If you wanted to use the $Time parameter, you would have to have something in the $link parameter, even if it's just a 1 which is the default.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

i ran this function just now . but i got error array variable has incorrect no of subscript

However if i call this parameter then script gets passed.

One thing more we mentioned optional parameters in " ".

But here we are not using " " .

shiv,

We need more than just the function definition line to help. Please post the code that gives the problem - then we an see what might be happening. :)
