NAME

OpenGuides::Template - Do Template Toolkit related stuff for OpenGuides applications.

DESCRIPTION

Does all the Template Toolkit 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

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

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

  print OpenGuides::Template->output( wiki     => $wiki,
                                      config   => $config,
                                      template => "node.tt",
                                      vars     => { foo => "bar" }
  );

METHODS

output

  print OpenGuides::Template->output( wiki         => $wiki,
                                      config       => $config,
                                      template     => "node.tt",
                                      content_type => "text/html",
                                      cookies      => $cookie,
                                      vars         => {foo => "bar"},
                                      noheaders    => 1
  );

Returns everything you need to send to STDOUT, including the Content-Type: header. Croaks unless template is supplied.

The config object and variables supplied in vars are passed through to the template specified. Additional Template Toolkit variables are automatically set and passed through as well, as described below. Note: variables set in vars will over-ride any variables of the same name in the config object or the user cookies.

• openguides_version
• site_name
• cgi_url
• full_cgi_url
• enable_page_deletion (gets set to true or false - defaults to false)
• contact_email
• stylesheet
• home_link
• formatting_rules_link (unless omit_formatting_link is set in user cookie)
• navbar_on_home_page
• home_name
• gmaps_api_key
• licence_name
• licence_url
• licence_info_url
• prefs (the preferences from the user cookie)

If node is supplied:

• node_name
• node_param (the node name escaped for use in URLs)

Content-Type: defaults to text/html and is omitted if the content_type arg is explicitly set to the blank string.

However, what you more often need is the noheaders option, which suppresses all HTTP headers, not just the Content-Type.

The HTTP response code may be explictly set with the http_status arg.

extract_metadata_vars

  my %node_data = $wiki->retrieve_node( "Home Page" );

  my %metadata_vars = OpenGuides::Template->extract_metadata_vars(
                          wiki     => $wiki,
                          config   => $config,
                          metadata => $node_data{metadata}
                      );

  # -- or --

  my %metadata_vars = OpenGuides::Template->extract_metadata_vars(
                          wiki     => $wiki,
                          config   => $config,
                          cgi_obj  => $q
                      );

  # -- then --

  print OpenGuides::Template->output(
            wiki     => $wiki,
            config   => $config,
            template => "node.tt",
            vars     => { foo => "bar",
                          %metadata_vars }
        );

Picks out things like categories, locales, phone number etc from EITHER the metadata hash returned by Wiki::Toolkit OR the query parameters in a CGI object, and packages them nicely for passing to templates or storing in Wiki::Toolkit datastore. If you supply both metadata and cgi_obj then metadata will take precedence, but don't do that.

The variables dist_field, coord_field_1, coord_field_1_name, coord_field_1_value, coord_field_2, coord_field_2_name, and coord_field_2_value, which are used to create various forms, will only be set if either metadata is supplied or set_coord_field_vars is true, to prevent these values from being stored in the database on a node commit.
