LWP::UserAgent POST, pass array?

ultranerds has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to work out why I don't seem to be able to pass an array of values along using LWP::UserAgent. Here is my code:

my $ua      = LWP::UserAgent->new();
my $request = POST( $url, [
        pdfColor => '#f7540e',

        proName => \@proName,
        proDesc => \@proDesc,
        amount => \@amount,
        price => \@price,
        vat => \@vat,
        discount => \@discount,
        total => \@total

        ] );
my $content = $ua->request($request)->as_string();
[download]

...the PHP script it calls, this is an output of what it sees:

Array
(
    [pdfColor] => #f7540e
    [proName] => test
    [proDesc] => Some description
    [amount] => 3
    [price] => 30
    [vat] => 0
    [discount] => 0
    [total] => 90
)
[download]

For some reason, the arrays I'm passing in - it only seems to get one of the entries. I've searched around, and it looks like passing in a referenced array should work just fine... but it doesn't wanna :/

UPDATE: I just came across this post:

http://stackoverflow.com/questions/20753253/perl-lwp-anoymous-array-reference-containing-array-reference-comes-across-as-arr

From the sounds of it, you can't actually pass an arrayref :( Bit rubbish, but as a work-around I am now just doing:

proDesc => join ("::::",@proDesc),

...and then decode it in the PHP code (using a "split"). Not ideal, but as long as it works =)

TIA

From the sounds of it, you can't actually pass an arrayref :( Sure you can. Here's a simple example: `#!/usr/bin/perl use strict; use warnings; use LWP; my $url = 'http://localhost/echo.cgi'; my $ua = LWP::UserAgent->new; my $res = $ua->post ($url, { foo => ['bar', 'baz'] }); print $res->as_string;` [download] Throw that at your handler and it will tell you that param "foo" has two values which are "bar" and "baz". If it doesn't, that's a bug in your handler and you'll need to head on over to PHPMonks to sort that out.	[reply] [d/l]

Ah weird - not sure why its not working for me. Anyhow, I've got it working by serializing the values, and then doing a split at the other end =) Not pretty, but works <G>	[reply]

~~nevermind~~ edit: I misunderstood your OP. I thought the values in your sample data were what you were passing in your arrayrefs, and I was going to ask why you are using arrays to begin with. The way forward always starts with a minimal test.	[reply] [d/l]
