Hi all, I need to loop over an array of hashes and assign a new hashref if a
condition is met:
I have a scalar which contains an array of hashes:
$locations = [
{
'location_name' => 'Fionas House',
'location_id' => '9999000000000027'
},
{
'location_name' => 'Central Locations',
'location_id' => '9999'
},
{
'location_name' => 'The Queen\'s Hoose',
'location_id' => '1076'
},
{
'location_name' => 'Santa',
'location_id' => '1075'
},
]
I want to add an new hash ref in if, for example,
if($x ==9999000000000027){
$locations->[0]->{'location_status'} = 'true'
}
I've been at this a few hours and I'm not getting anywhere, can anyone
suggest a way to do this?
An reference to an array can be dereferenced to an array:
for my $item ( @$locations ){ # $item references each hash in the list
if( $item->{location_id} == 9999000000000027 ){
$item->{location_status} = 'true';
}
}
