    在注册表单创建期间,在表单验证期间,还有在用户记录被插入到数据库中以后,都要调用user钩子。我们这个简单的模块将生成类似于图6-2所示的注册表单。

官方勘误:http://www.drupalbook.com/errata2?page=2 Page 123

Error: 

case 'insert':
// Record information for future lawsuit.
watchdog('user', t('User %user agreed to legal terms',
array('%user' => $user->name)));
break;

Correction: 

case 'insert':
// Record information for future lawsuit.
$name = $edit['name'];
watchdog('user', t('User %user agreed to legal terms',
array('%user' => $name)));
break;

Description of the Error: 

when operation insert happen, the user object is still loaded as anonymous, so $user->name get any information.
To get the new user's name you have to use the $edit variable who content the value submit by the new user in a array. So to get the name you have to use $edit['name'].
