%SHORTDESCRIPTION%

---++ Introduction

Allows editing of preferences using fields predefined in a %SYSTEMWEB%.TWikiForms. However, the edit fields are inlined in the text, similar to how tables are edited in EditTablePlugin.

Insert the =%<nop>EDITPREFERENCES%= variable (see below) anywhere in your topic. It will be replaced by a button that allows editing each preference in its predefined input format (or a text box, when no format is defined for this preference).

In edit mode, the edit button is replaced by Save and Cancel buttons, with their obvious meanings.

---++ Syntax Rules

   * =%<nop>EDITPREFERENCES{ "topic" editbutton="..." }%=
      * =topic= references a [[%SYSTEMWEB%.TWikiForms][TWikiForm]] defining the format of the edit fields for preferences. It may be prefixed by a web.
      * Optional =editbutton= parameter: Custom edit button label. Default: Edit Preferences.
      * If a preference setting is not mentioned in the form referenced by _topic_, a text input box of the specified length is provided.
      * Otherwise, the input can be through textareas, select, radio, checkbox, date, or text, as provided by %SYSTEMWEB%.TWikiForms.
   * =%<nop>EDITPREFERENCES%=
      * Edit existing preferences in the topic using a simple text field.

---++ Examples

   * =%<nop>EDITPREFERENCES%=
   * =%<nop>EDITPREFERENCES{ "%<nop>SYSTEMWEB%.TWikiPreferencesForm" }%=
   * =%<nop>EDITPREFERENCES{ "%<nop>SYSTEMWEB%.TWikiPreferencesForm" editbutton="Edit Group Settings" }%=

---++ Caveat

When the "Edit Preferences" button is clicked, the page is rendered in such a manner that it makes a big HTML form to update preferences.
This form generation processing assumes that there is no HTML form tags (form, input, select, option, textarea tags) are present in the !WebPreferences content.
If HTML forms are present on !WebPreferences, "Edit Preferences" may generate an HTML form not functioning well.

Meanwhile you may put HTML forms in [[%SYSTEMWEB%.WebPreferences]], which is included in every !WebPreferences.
To cope with that, inclusion of that topic is suppressed when "Edit Prefereces" is clicked.

|  15 Apr 2006: | Adding css classes to buttons. Removed debug print statement causing 500s on !SunOne. Prevent extra space in settings on saves. Switched to earlier handler. Converted all SCRIPTURL to SCRIPTURLPATH, and added support. The only SCRIPTURLs should be the one in the BASE tag and those in mail notification templates. Because the forms package was throwing an exception when it failed to create a form, the edit preferences plugin was aborting the whole of the session whenever the form specified in EDITPREFERENCES didn't exist. Changed it so that the Form constructor does not throw, but returns undef on a non-existant form, and changed preferences plugin to be tolerant of missing forms (ie defaults all fields to text if the form is missing, of is a Set exists which is not in the form). |
