A list of if's rather then 10 elsif	Can't Post

Hi,

I have a series of 10 fields that I want to check if they have data in them. If any of them do, I want to perform a task. Here is the problem, I have 10 elsif's and it get's very cluttered. Is there a way to have a if list. So that if one the if's are true it will do the task.

I hope you understand the question

Thanks

No ;-)

Perhaps you post your code excerpt with the elsif's or the complete script and we'll see.

I'm not sure I understand either, but I'll give it a shot anyway.

Let's say your input is in a hash.

Code

my %fields = ( 
    1 => '', 
    2 => '2', 
    3 => '', 
    4 => '4', 
); 
  
my $count = grep{ $_ } values %fields;

Above is a simple hash with some empty entries. Then, using grep, we assign $count with the count of true values in $fields. $count will be 0 ( false ) if there's no true values entered. So you can use:

Code

if ( $count ){ 
    # values exist, do something. 
}

Hope this helps!
