Used from with a template, it would look something like the following: .PP .Vb 3 \& [% USE url(\*(Aqhttp://www.somewhere.com/cgi\-bin/foo.pl\*(Aq) %] \& [% USE url(\*(Aq/cgi\-bin/bar.pl\*(Aq, mode=\*(Aqbrowse\*(Aq) %] \& [% USE url(\*(Aq/cgi\-bin/baz.pl\*(Aq, mode=\*(Aqbrowse\*(Aq, debug=1) %] .Ve .PP When the plugin is then called without any arguments, the default base and parameters are returned as a formatted query string. .PP .Vb 1 \& [% url %] .Ve .PP For the above three examples, these will produce the following outputs: .PP .Vb 3 \& http://www.somewhere.com/cgi\-bin/foo.pl \& /cgi\-bin/bar.pl?mode=browse \& /cgi\-bin/baz.pl?mode=browse&debug=1 .Ve .PP Note that additional parameters are separated by '\f(CW\*(C`&\*(C'\fR' rather than simply '\f(CW\*(C`&\*(C'\fR'. This is the correct behaviour for \s-1HTML\s0 pages but is, unfortunately, incorrect when creating URLs that do not need to be encoded safely for \s-1HTML\s0. This is likely to be corrected in a future version of the plugin (most probably with \s-1TT3\s0). In the mean time, you can set \f(CW$Template::Plugin::URL::JOINT\fR to \f(CW\*(C`&\*(C'\fR to get the correct behaviour. .PP Additional parameters may be also be specified to the \s-1URL:\s0 .PP .Vb 1 \& [% url(mode=\*(Aqsubmit\*(Aq, id=\*(Aqwiz\*(Aq) %] .Ve .PP Which, for the same three examples, produces: .PP .Vb 3 \& http://www.somewhere.com/cgi\-bin/foo.pl?mode=submit&id=wiz \& /cgi\-bin/bar.pl?mode=browse&id=wiz \& /cgi\-bin/baz.pl?mode=browse&debug=1&id=wiz .Ve .PP A new base \s-1URL\s0 may also be specified as the first option: .PP .Vb 1 \& [% url(\*(Aq/cgi\-bin/waz.pl\*(Aq, test=1) %] .Ve .PP producing .PP .Vb 3 \& /cgi\-bin/waz.pl?test=1 \& /cgi\-bin/waz.pl?mode=browse&test=1 \& /cgi\-bin/waz.pl?mode=browse&debug=1&test=1 .Ve .PP The ordering of the parameters is non-deterministic due to fact that Perl's hashes themselves are unordered. This isn't a problem as the ordering of \s-1CGI\s0 parameters is insignificant (to the best of my knowledge). All values will be properly escaped thanks to some code borrowed from Lincoln Stein's \f(CW\*(C`CGI\*(C'\fR module. e.g. .PP .Vb 2 \& [% USE url(\*(Aq/cgi\-bin/woz.pl\*(Aq) %] \& [% url(name="Elrich von Benjy d\*(AqWeiro") %] .Ve .PP Here the spaces and "\f(CW\*(C`\*(Aq\*(C'\fR" character are escaped in the output: .PP .Vb 1 \& /cgi\-bin/woz.pl?name=Elrich%20von%20Benjy%20d%27Weiro .Ve .PP An alternate name may be provided for the plugin at construction time as per regular Template Toolkit syntax. .PP .Vb 2 \& [% USE mycgi = url(\*(Aqcgi\-bin/min.pl\*(Aq) %] \& [% mycgi(debug=1) %] .Ve .SH "AUTHOR" .IX Header "AUTHOR" Andy Wardley .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (C) 1996\-2007 Andy Wardley.
