I know twisted.web.widgets is deprecated, but I still have lots of code using it. So, here's a new feature: Form support for radio buttons. They work pretty much equally to checkgroups. I didn't see a point in supporting a single radio button, so I only implemented the group support. If nobody complains, I'll commit this soonish: Index: twisted/web/widgets.py =================================================================== RCS file: /cvs/Twisted/twisted/web/widgets.py,v retrieving revision 1.72 diff -u -r1.72 widgets.py --- twisted/web/widgets.py 16 Nov 2002 08:10:33 -0000 1.72 +++ twisted/web/widgets.py 29 Dec 2002 17:09:56 -0000 @@ -244,6 +244,12 @@ checked = (checked and 'checked = "1"') or '' write('<INPUT TYPE="checkbox" NAME="%s" VALUE="%s" %s />%s<br />\n' % (name, optionName, checked, displayName)) +def htmlFor_radio(write, name, value): + "A radio button group." + for optionName, displayName, checked in value: + checked = (checked and 'checked = "1"') or '' + write('<INPUT TYPE="radio" NAME="%s" VALUE="%s" %s />%s<br />\n' % (name, optionName, checked, displayName)) + class FormInputError(Exception): pass @@ -283,7 +289,8 @@ 'multimenu': htmlFor_multimenu, 'password': htmlFor_password, 'checkbox': htmlFor_checkbox, - 'checkgroup': htmlFor_checkgroup + 'checkgroup': htmlFor_checkgroup, + 'radio': htmlFor_radio, } formParse = { @@ -325,6 +332,8 @@ - 'checkgroup': a group of checkboxes + - 'radio': a group of radio buttons + - 'password': a 'string' field where the contents are not visible as the user types - 'file': a file-upload form (EXPERIMENTAL) @@ -339,8 +348,8 @@ The 'Input Value' is usually a string, but its value can depend on the 'Input Type'.
