.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`URL\*(C'\fR plugin can be used to construct complex URLs from a base stem
and a hash array of additional query parameters.
.PP
The constructor should be passed a base \s-1URL\s0 and optionally, a hash array
reference of default parameters and values. Used from with a template,
it would look something like the following:
.PP
.Vb 3
\& [% USE url('http://www.somewhere.com/cgi-bin/foo.pl') %]
\& [% USE url('/cgi-bin/bar.pl', mode='browse') %]
\& [% USE url('/cgi-bin/baz.pl', mode='browse', 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='submit', id='wiz') %]
.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('/cgi-bin/waz.pl', 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('/cgi-bin/woz.pl') %]
\& [% url(name="Elrich von Benjy d'Weiro") %]
.Ve
.PP
Here the spaces and "\f(CW\*(C`'\*(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('cgi-bin/min.pl') %]
\& [% mycgi(debug=1) %]
