HTTPRequestHotfix Product

This so called Hotfix adds the new method query_string to the HTTPRequest class. The method is then accessible through the REQUEST object.

It builds a url quoted (quote_plus) query string from a dictionary (usually from the form dictionary which is based on QUERY_STRING).

Usage

query_string([[replace]=replace_dict], [[original]=original_dict]])

Updates original_dict by the values in replace_dict and returns the result as url quoted query string.

original_dict defaults to REQUEST.form if no parameter is passed to it. Keys in replace_dict with a value of None (or _.None in DTML) will be deleted from original_dicts before being quoted.

The original REQUEST.form will remain unchanged.

Examples

(assuming REQUEST.form is {'foobar':no translation, 'foo':'bar'})

1. query_string(replace={'foobar':'furchtbar in german'}) returns foobar=furchtbar+in+german&foo=bar
2. query_string(replace={'gaga':'&%+'}, original={bar, 'foo'}) returns gaga=26%25%2b&bar=foo
3. query_string(replace={'bar':foo, foo, _.None}) returns foobar=no+translation&bar=foo
4. The same in DTML: <dtml-var "REQUEST.query_string(replace={'bar':foo, foo, _.None})"> returns foobar=no+translation&bar=foo

Have fun!
