NAME
Template::Plugin::URL - Plugin to construct complex URLs
SYNOPSIS
[% USE url('/cgi-bin/foo.pl') %]
[% url(debug = 1, id = 123) %]
# ==> /cgi/bin/foo.pl?debug=1&id=123
[% USE mycgi = url('/cgi-bin/bar.pl', mode='browse', debug=1) %]
[% mycgi %]
# ==> /cgi/bin/bar.pl?mode=browse&debug=1
[% mycgi(mode='submit') %]
# ==> /cgi/bin/bar.pl?mode=submit&debug=1
[% mycgi(debug='d2 p0', id='D4-2k[4]') %]
# ==> /cgi-bin/bar.pl?mode=browse&debug=d2%20p0&id=D4-2k%5B4%5D
DESCRIPTION
The "URL" plugin can be used to construct complex URLs from a base stem and a hash array of additional query parameters.
The constructor should be passed a base URL and optionally, a hash array reference of default parameters and values. Used from with a
template, it would look something like the following:
[% 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) %]
When the plugin is then called without any arguments, the default base and parameters are returned as a formatted query string.
[% url %]
For the above three examples, these will produce the following outputs:
http://www.somewhere.com/cgi-bin/foo.pl
/cgi-bin/bar.pl?mode=browse
/cgi-bin/baz.pl?mode=browse&debug=1
Note that additional parameters are separated by '"&"' rather than simply '"&"'. This is the correct behaviour for HTML pages but is,
unfortunately, incorrect when creating URLs that do not need to be encoded safely for HTML. This is likely to be corrected in a future
version of the plugin (most probably with TT3). In the mean time, you can set $Template::Plugin::URL::JOINT to "&" to get the correct
behaviour.
Additional parameters may be also be specified to the URL:
[% url(mode='submit', id='wiz') %]
Which, for the same three examples, produces:
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
A new base URL may also be specified as the first option:
[% url('/cgi-bin/waz.pl', test=1) %]
producing
/cgi-bin/waz.pl?test=1
/cgi-bin/waz.pl?mode=browse&test=1
/cgi-bin/waz.pl?mode=browse&debug=1&test=1
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 CGI parameters is insignificant (to the best of my knowledge). All values will be properly escaped thanks to some code
borrowed from Lincoln Stein's "CGI" module. e.g.
[% USE url('/cgi-bin/woz.pl') %]
[% url(name="Elrich von Benjy d'Weiro") %]
Here the spaces and ""'"" character are escaped in the output:
/cgi-bin/woz.pl?name=Elrich%20von%20Benjy%20d%27Weiro
An alternate name may be provided for the plugin at construction time as per regular Template Toolkit syntax.
[% USE mycgi = url('cgi-bin/min.pl') %]
[% mycgi(debug=1) %]
