Perl Mojolicious array loop

Not sure if this is even possible. But I am trying to loop over an array. I keep getting the error message Can't use an array as a reference on the for loop line. $product_results->[6] does contain data.

Can't use an array as a reference

$product_results->[6]

my @product_array = split(',', $order->[6]);
$product_results->[6] = @product_array;
% for (@$product_results->[6])
<%= $_->[0] %>
%

You are using both forms of dereferencing at once.

Either use

$ref->[6];


or

@$ref[6];


Both at the same time will Perl dereference the reference as an array into something like this, and then dereference that as an array reference to get the 7th element. But that doesn't work.

(1, 2, 3)->[7]


What you actually want to do is dereference the array ref that is inside your seventh index in the array reference.

# this will deref the content of index 7
# | this will deref $ref into an array
# | |
@ $ref->[7]


To illustrate forther, your data structure looks like this.

$ref = [
0,
1,
2,
3,
4,
5,
6,
[ # 7
qw/ foo bar baz/
],
]
