The second way to add options to one of the SquirrelMail preferences page is
to use one of the "optpage_loadhook_<pref page>" hooks. The sent_subfolders
-plugin is an excellent example of this method. Briefly, this way of adding
+plugin has an excellent example of this method. Briefly, this way of adding
options consists of adding some plugin-specific information to a predefined
data structure which SquirrelMail then uses to build the HTML input forms
for you. This is the preferred method of building options lists going forward.
SMOPT_TYPE_INTEGER Integer input
SMOPT_TYPE_FLOAT Floating point number input
SMOPT_TYPE_BOOLEAN Boolean (yes/no radio buttons)
- input

SMOPT_TYPE_HIDDEN Hidden input (not actually

+ 1 - Mailbox Display Options
+ 2 - Message Display and Composition

+ 'name' => 'plugin_demo_favorite_color',
+ 'caption' => 'Please Choose Your Favorite Color',
+ 'type' => SMOPT_TYPE_STRLIST,
+ 'refresh' => SMOPT_REFRESH_ALL,
+ 'posvals' => array(0 => 'red',
+ 1 => 'blue',
+ 2 => 'green',
+ 3 => 'orange'),
+ 'save' => 'save_plugin_demo_favorite_color'
+ );

3. If you indicated a 'save' attribute for any of your options, you must
create that function (you'll only need to do this if you need to do
some special processing for one of your settings). The function gets
