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.

every_param

  my $values = $params->every_param('foo');

Similar to "param", but returns all values sharing the same name as an array reference. Note that this method will normalize the parameters.

  # Get first value
  say $params->every_param('foo')->[0];

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 $value       = $params->param('foo');
  my ($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']);

Access parameter values. If there are multiple values sharing the same name, and you want to access more than just the last one, you can use "every_param". 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".
