A FEW NOTES ON THE PLUGIN ARCHITECTURE
1.7. class/mime/Language.class.php
1.8. class/mime/ContentType.class.php
2. functions/global.php
+ * fixes differences between php 4.0.x and 4.1+ globals (only in 1.4.x).
+ * undoes magic_quotes_gpc=on sanitizing
+ * sets $PHP_SELF (since 1.5.1)
+ * starts session
3. functions/strings.php
+ 3.1. functions/global.php
+ 3.2. plugins/compatibility/functions.php (compatibility v.2.0.4+, requires
+ code patching)
+ * sets squirrelmail version variable and constant.
+ * sets $PHP_SELF (before 1.5.1)
4. config/config.php
4.1. config/config_local.php (from 1.4.0rc1)
5. functions/i18n.php
5.1. functions/global.php (from 1.4.0)
+ * reads 'squirrelmail_language' cookie
+ * loads $languages (since 1.5.1 $languages array is built from
+ locale/*/setup.php files)
+ * loads own gettext functions, if php gettext is unavailable
6. functions/auth.php
7. include/load_prefs.php
7.1. include/validate.php
7.2. functions/prefs.php
+ 7.2.1. functions/global.php (sqgetGlobalVar() function)
+ 7.2.2. functions/plugin.php (do_hook_function() function,,
+ since 1.4.4 and 1.5.1, see 7.3)
+ 7.2.3. $prefs_backend (only in 1.4.3 and 1.5.0)
+ do_hook_function('prefs_backend') (since 1.4.4 and 1.5.1)
+ functions/db_prefs.php
+ functions/file_prefs.php
+ 7.2.3.1. functions/display_messages.php
+ (loaded only by file_prefs.php)
+ 7.2.3.2. files loaded by plugin that uses 'prefs_backend' hook
7.3. functions/plugin.php
7.3.1. functions/global.php (from 1.4.0 and 1.5.0)
7.3.2. functions/prefs.php (from 1.5.1)
+ 7.3.3. plugins/*/setup.php files for enabled plugins.
+ * starts all squirrelmail_plugin_init_pluginname functions
7.4. functions/constants.php
7.5. do_hook('loading_prefs')
- 7.5.1. files loaded by plugins that use 'loading_prefs'
+ 7.5.1. files loaded by plugins that use 'loading_prefs' hook
8. functions/page_header.php
8.1. functions/strings.php
8.2. functions/html.php
8.3. functions/imap_mailbox.php
8.3.1. functions/imap_utf7_local.php
8.4. functions/global.php
- 9. functions/prefs.php
- 9.1. functions/global.php
- 9.2. $prefs_backend (only in 1.4.3 and 1.5.0)
- do_hook_function('prefs_backend') (since 1.4.4 and 1.5.1)
- functions/db_prefs.php
- functions/file_prefs.php
- 9.2.1. functions/display_messages.php
- (loaded only by file_prefs.php)
- 9.2.2. files loaded by plugin that uses 'prefs_backend'
+ 9. functions/prefs.php (already loaded. see 7.2)
+
+Since SquirrelMail 1.5.1 functions/global.php file must be loaded before
+setting any own global variables. If variables are set before loading
+functions/global.php library, they can be corrupted in PHP register_globals=On
+setups.

+! = See below for notes about working with the compose page's <form> tag
(#) Called With
concat_hook concat_hook_function()
+(!) Compose Form
+----------------
+The compose_form hook allows plugins to insert their own code into
+the form tag for the main message composition HTML form. Usually
+plugins will want to insert some kind of code in an onsubmit event
+handler. In order to allow more than one plugin to do so, all plugins
+using this hook to add some onsubmit code need to add that code (without
+the enclosing attribute name and quotes) as a new array entry to the
+global $compose_onsubmit array. The code should use "return false"
+if the plugin has found a reason to stop form submission, otherwise,
+it should DO NOTHING (that is, please do not use "return true", as that
+will prevent other plugins from using the onsubmit handler). SquirrelMail
+itself will insert a final "return true". All onsubmit code will be
+enclosed in double quotes by SquirrelMail, so plugins need to quote
+accordingly if needed. For example:
+
+ global $compose_onsubmit;
+ $compose_onsubmit[] = ' if (somevar == \'no\') return false; ';
+
+Note the escaped single quotes. If you use double quotes, they would have
+to be escaped as such:
+
+ global $compose_onsubmit;
+ $compose_onsubmit[] = ' if (somevar == \'no\') { alert(\\"Sorry\\"); return false; }';
+
+Any other form tag additions by a plugin (beside onsubmit event code) can
+currently be echoed directly to the browser.
+
+
(&) Identity Hooks
------------------
This set of hooks is passed special information in the array of arguments:
accomplish the internationalization of a plugin. For more general information
about PHP and SquirrelMail translation facilities, see:
-http://www.squirrelmail.org/wiki/wiki.php?LanguageTranslation
+http://www.squirrelmail.org/wiki/LanguageTranslation
The unofficial way to internationalize a plugin is to put all plugin output
into the proper format but to rely on the SquirrelMail translation facilities
global $favorite_color;
sqgetGlobalVar('favorite_color', $favorite_color, SQ_FORM);
+SquirrelMail 1.5.1+ cleans globals in functions/global.php library. If
+plugin depends on PHP register_globals=On and loads this library, it will
+be broken.
+
