- * Licensed under the GNU GPL. For full terms see the file COPYING.
- *
* This contains functions for manipulating user preferences
- * stored in a database, accessed though the Pear DB layer.
- *
- * To use this instead of the regular prefs.php, create a
- * database as described below, and replace prefs.php
- * with this file.
+ * stored in a database, accessed through the Pear DB layer
+ * or PDO, the latter taking precedence if available.
*
* Database:
- * ---------
*
- * The preferences table should have tree columns:
- * username char \ primary
+ * The preferences table should have three columns:
+ * user char \ primary
* prefkey char / key
* prefval blob
*
- * CREATE TABLE userprefs (user CHAR(32) NOT NULL DEFAULT '',
+ * CREATE TABLE userprefs (user CHAR(128) NOT NULL DEFAULT '',
* prefkey CHAR(64) NOT NULL DEFAULT '',
* prefval BLOB NOT NULL DEFAULT '',
* primary key (user,prefkey));
*
* Configuration of databasename, username and password is done
- * by changing $DSN below.
+ * by using conf.pl or the administrator plugin
*
- * $Id$
+ * Three settings that control PDO behavior can be specified in
+ * config/config_local.php if needed:
+ * boolean $disable_pdo SquirrelMail uses PDO by default to access the
+ * user preferences and address book databases, but
+ * setting this to TRUE will cause SquirrelMail to
+ * fall back to using Pear DB instead.
+ * boolean $pdo_show_sql_errors When database errors are encountered,
+ * setting this to TRUE causes the actual
+ * database error to be displayed, otherwise
+ * generic errors are displayed, preventing
+ * internal database information from being
+ * exposed. This should be enabled only for
+ * debugging purposes.
+ * string $pdo_identifier_quote_char By default, SquirrelMail will quote
+ * table and field names in database
+ * queries with what it thinks is the
+ * appropriate quote character for the
+ * database type being used (backtick
+ * for MySQL (and thus MariaDB), double
+ * quotes for all others), but you can
+ * override the character used by
+ * putting it here, or tell SquirrelMail
+ * NOT to quote identifiers by setting
+ * this to "none"
