NAME

Mojo::Parameters - Parameters

SYNOPSIS

  use Mojo::Parameters;

  # Parse
  my $params = Mojo::Parameters->new('foo=bar&baz=23');
  say $params->param('baz');

  # Build
  my $params = Mojo::Parameters->new(foo => 'bar', baz => 23);
  push @$params, i => '♥ mojolicious';
  say "$params";

DESCRIPTION

Mojo::Parameters is a container for form parameters used by Mojo::URL and based on RFC 3986 as well as the HTML Living Standard.

ATTRIBUTES

Mojo::Parameters implements the following attributes.

charset

  my $charset = $params->charset;
  $params     = $params->charset('UTF-8');

Charset used for encoding and decoding parameters, defaults to UTF-8.

  # Disable encoding and decoding
  $params->charset(undef);

METHODS

Mojo::Parameters inherits all methods from Mojo::Base and implements the following new ones.

append

  $params = $params->append(foo => 'ba&r');
  $params = $params->append(foo => ['ba&r', 'baz']);
  $params = $params->append(foo => ['bar', 'baz'], bar => 23);

Append parameters. Note that this method will normalize the parameters.

  # "foo=bar&foo=baz"
  Mojo::Parameters->new('foo=bar')->append(foo => 'baz');

  # "foo=bar&foo=baz&foo=yada"
  Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada']);

  # "foo=bar&foo=baz&foo=yada&bar=23"
  Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada'], bar => 23);

clone

  my $params2 = $params->clone;

Clone parameters.

merge

  $params = $params->merge(Mojo::Parameters->new(foo => 'b&ar', baz => 23));

Merge Mojo::Parameters objects. Note that this method will normalize the parameters.

new

  my $params = Mojo::Parameters->new;
  my $params = Mojo::Parameters->new('foo=b%3Bar&baz=23');
  my $params = Mojo::Parameters->new(foo => 'b&ar');
  my $params = Mojo::Parameters->new(foo => ['ba&r', 'baz']);
  my $params = Mojo::Parameters->new(foo => ['bar', 'baz'], bar => 23);

Construct a new Mojo::Parameters object and "parse" parameters if necessary.

param

  my @names       = $params->param;
  my $foo         = $params->param('foo');
  my @foo         = $params->param('foo');
  my ($foo, $bar) = $params->param(['foo', 'bar']);
  $params         = $params->param(foo => 'ba&r');
  $params         = $params->param(foo => qw(ba&r baz));
  $params         = $params->param(foo => ['ba;r', 'baz']);

Check and replace parameter value. Be aware that if you request a parameter by name in scalar context, you will receive only the first value for that parameter, if there are multiple values for that name. In list context you will receive all of the values for that name. Note that this method will normalize the parameters.

params

  my $array = $params->params;
  $params   = $params->params([foo => 'b&ar', baz => 23]);

Parsed parameters. Note that this method will normalize the parameters.

parse

  $params = $params->parse('foo=b%3Bar&baz=23');

Parse parameters.

remove

  $params = $params->remove('foo');

Remove parameters. Note that this method will normalize the parameters.

  # "bar=yada"
  Mojo::Parameters->new('foo=bar&foo=baz&bar=yada')->remove('foo');

to_hash

  my $hash = $params->to_hash;

Turn parameters into a hash reference. Note that this method will normalize the parameters.

  # "baz"
  Mojo::Parameters->new('foo=bar&foo=baz')->to_hash->{foo}[1];

to_string

  my $str = $params->to_string;

Turn parameters into a string.

OPERATORS

Mojo::Parameters overloads the following operators.

array

  my @params = @$params;

Alias for "params". Note that this will normalize the parameters.

  say $params->[0];
  say for @$params;

bool

  my $bool = !!$params;

Always true.

stringify

  my $str = "$params";

Alias for "to_string".
