NAME

OpenGuides::CGI - An OpenGuides helper for CGI-related things.

DESCRIPTION

Does CGI stuff for OpenGuides. Distributed and installed as part of the OpenGuides project, not intended for independent installation. This documentation is probably only useful to OpenGuides developers.

SYNOPSIS

Saving preferences in a cookie:

use OpenGuides::CGI;
use OpenGuides::Config;
use OpenGuides::Template;
use OpenGuides::Utils;

my $config = OpenGuides::Config->new( file => "wiki.conf" );

my $cookie = OpenGuides::CGI->make_prefs_cookie(
    config                     => $config,
    username                   => "Kake",
    include_geocache_link      => 1,
    preview_above_edit_box     => 1,
    latlong_traditional        => 1,
    omit_help_links            => 1,
    show_minor_edits_in_rc     => 1,
    default_edit_type          => "tidying",
    cookie_expires             => "never",
    track_recent_changes_views => 1,
    display_google_maps        => 1,
    is_admin                   => 1
);

my $wiki = OpenGuides::Utils->make_wiki_object( config => $config );
print OpenGuides::Template->output( wiki     => $wiki,
                                    config   => $config,
                                    template => "preferences.tt",
                                    cookies  => $cookie
);

# and to retrive prefs later:
my %prefs = OpenGuides::CGI->get_prefs_from_cookie(
    config => $config
);

Tracking visits to Recent Changes:

use OpenGuides::CGI;
use OpenGuides::Config;
use OpenGuides::Template;
use OpenGuides::Utils;

my $config = OpenGuides::Config->new( file => "wiki.conf" );

my $cookie = OpenGuides::CGI->make_recent_changes_cookie(
    config => $config,
);

METHODS

extract_node_param
my $config_file = $ENV{OPENGUIDES_CONFIG_FILE} || "wiki.conf";
my $config = OpenGuides::Config->new( file => $config_file );
my $guide = OpenGuides->new( config => $config );
my $wiki = $guide->wiki;

my $q = CGI->new;

my $node_param = OpenGuides::CGI->extract_node_param(
                    wiki => $wiki, cgi_obj => $q );

Returns the title, id, or keywords parameter from the URL. Normally this will be something like "British_Museum", i.e. with underscores instead of spaces. However if the URL does contain spaces (encoded as %20 or +), the return value will be e.g. "British Museum" instead.

Croaks unless a Wiki::Toolkit object is supplied as wiki and a CGI object is supplied as cgi_obj.

extract_node_name
my $config_file = $ENV{OPENGUIDES_CONFIG_FILE} || "wiki.conf";
my $config = OpenGuides::Config->new( file => $config_file );
my $guide = OpenGuides->new( config => $config );
my $wiki = $guide->wiki;

my $q = CGI->new;

my $node_name = OpenGuides::CGI->extract_node_name(
                    wiki => $wiki, cgi_obj => $q );

Returns the name of the node the user wishes to display/manipulate, as we expect it to be stored in the database. Normally this will be something like "British Museum", i.e. with spaces in. Croaks unless a Wiki::Toolkit object is supplied as wiki and a CGI object is supplied as cgi_obj.

check_spaces_redirect
my $config_file = $ENV{OPENGUIDES_CONFIG_FILE} || "wiki.conf";
my $config = OpenGuides::Config->new( file => $config_file );
my $guide = OpenGuides->new( config => $config );

my $q = CGI->new;

my $url = OpenGuides::CGI->check_spaces_redirect(
                             wiki => $wiki, cgi_obj => $q );

If the user seems to have typed a URL with spaces in the node param instead of underscores, this method will return the URL with the underscores put in. Otherwise, it returns false.

my $cookie = OpenGuides::CGI->make_prefs_cookie(
    config                     => $config,
    username                   => "Kake",
    include_geocache_link      => 1,
    preview_above_edit_box     => 1,
    latlong_traditional        => 1,
    omit_help_links            => 1,
    show_minor_edits_in_rc     => 1,
    default_edit_type          => "tidying",
    cookie_expires             => "never",
    track_recent_changes_views => 1,
    display_google_maps        => 1,
    is_admin                   => 1
);

Croaks unless an OpenGuides::Config object is supplied as config. Acceptable values for cookie_expires are never, month, year; anything else will default to month.

my %prefs = OpenGuides::CGI->get_prefs_from_cookie(
    config => $config,
    cookies => \@cookies
);

Croaks unless an OpenGuides::Config object is supplied as config. Returns default values for any parameter not specified in cookie.

If cookies is provided, this overrides any cookies submitted by the browser.

my $cookie = OpenGuides::CGI->make_recent_changes_cookie(
    config => $config,
);

Makes a cookie that stores the time now as the time of the latest visit to Recent Changes. Or, if clear_cookie is specified and true, makes a cookie with an expiration date in the past:

my $cookie = OpenGuides::CGI->make_recent_changes_cookie(
    config       => $config,
    clear_cookie => 1,
);
my %prefs = OpenGuides::CGI->get_last_recent_changes_visit_from_cookie(
    config => $config
);

Croaks unless an OpenGuides::Config object is supplied as config. Returns the time (as seconds since epoch) of the user's last visit to Recent Changes.
