[SR-Users] Condition Statements - How many levels

[Joel White]

I was wondering how many levels deep in conditional _if_ _else_
statements can go. I need to create a statement that has 4 possible
outcomes and need to know if this is possible.

I have two variables

I want one thing to happen if only the first variable is present

Another if only the second variable is present

Yet another if they are both present

And a fail over if None of the variables are present



I do see that is can be done with 3 conditions using _if_ _if else_
_else_

how can I accomplish 4 conditional statements?


Thank you in advance

Joel

Joel,

You are looking for something like this logically:

if(!($var(is_a_present) == $null && $var(is_b_present))){
# a and b exist
} else if(!($var(is_a_present) == $null){
# a exists
} else if(!($var(is_b_present) == $null)){
# b exists
} else {
# failover
}

Sincerely,
Brandon Armstead

Joel,

Forgot second half of initial if

if(!($var(is_a_present) == $null && $var(is_b_present) *== $null)*){
# a and b exist
} else if(!($var(is_a_present) == $null){
# a exists
} else if(!($var(is_b_present) == $null)){
# b exists
} else {
# failover
}
