Re: Reference to a single array item in an array of hashes?

[tedrek]

You can just use the built in aliasing of for loops, (I'm assuming this loop is initializing the array):

#!/usr/bin/perl
use strict;
use warnings;

my $numTimes = 2;
my $i = 0;
my @jobTimes = ('') x $numTimes; # Make the array big enough

foreach my $job (@jobTimes)
{
    $job = {
        start => param("JobStart$i"),
    };
    $i++;
}

Update: made it compile and do what I mean.

Using that code gives an error "Global symbol "$job" requires explicit package name".

I tried changing it to this:

foreach my %job (@jobTimes)

but it didn't like that either. Syntax error.

I fixed a few things. But you shouldn't be getting that error unless you are trying to use $job outside of the loop.

Teach me not to list enough code. It's actually erroring a little later in the loop. Here's the full loop:

my $i = 0;
my @jobTimes = ('') x $numTimes;    #initialize array
foreach my $job (@jobTimes)
{
    $job = {
            start   => param("JobStart$i"),
            end     => param("JobEnd$i"),
    };
    $job{'start'} =~ s/^0+//;
    $job{'end'} =~ s/^0+//;
    $i++;
}

It's giving the "Global Symbol "%job" requires explicit package" error on the regexpen.
