eRuby and URL rewriting
I am in the process of doing some web page authoring using eRuby.
My question is this-- how do I access the post/get information in URL
rewriting? I know in PHP you use something like
$_GET["key"]
given the following URL: [url]http://www.xyz.com/index.html?key=RUBYRULZ[/url]
Does eRuby have the equivalent?

I'm sure you just meant that as an example of how to access the query
string directly, but FYI, it's broken in other ways too-- modern
browsers are allowed to use ';' to separate variables in a GET
request. In fact, I believe it is now the preferred form. Much
friendlier to do:
cgi.keys.each { |key| p cgi[key] }
anyway :)

the URL in the case of a GET or in the header in the case of a POST.
For example, given the following form:
<html>
<body>
<form method="get">
What kinds of fruit do you like? <br />
<input type="checkbox" name="fruit" value="apples" /> Apples <br />
<input type="checkbox" name="fruit" value="oranges" /> Oranges <br />
<input type="checkbox" name="fruit" value="cherries"/> Cherries <br
/>
<input type="submit" />
</form>
</body>
</html>
If you check Apples and Oranges, then press submit the following url will be
submitted:
[url]http://myurl.com/?fruit=apples&fruit=Oranges[/url]
So:
cgi.params["fruit"] #=> ["apples","oranges"]
If you intend to only allow one value to be submitted, just use Array#first:
fruit = cgi.params["fruit"].first #=> "apples"
I used to think that this was a frustrating syntax, but I now realize this
is an essential part of the HTTP spec.
