Question

我在文件'doodil.install'中定义了以下架构，作为我正在编写的自定义模块的一部分。然而，每次我在Drupal中启用模块时，我都会看到死亡的白屏。 doodil.install的代码如下所示：

<?php
function doodil_schema() {
    $schema['doodil_user'] = array(
      'description' => t('The table containing users who have signed up for the chance to register.'),
      'fields' => array(
        'id' => array(
        'description' => t('Primary Key ID'),
        'type' => 'serial',
        'unsigned' => TRUE,
        'not null' => TRUE,
      ),
      'email_address' => array(
        'description' => t('User\'s Email Address'),
        'type' => 'varchar',
        'length' => 255,
        'not null' => TRUE,
      ),
      'first_name' => array(
        'description' => t('User\'s First Name'),
        'type' => 'varchar',
        'length' => 255,
        'not null' => TRUE,
      ),
      'last_name' => array(
        'description' => t('User\'s Last Name'),
        'type' => 'varchar',
        'length' => 255,
      ),
      'user_hash' => array(
        'description' => t('A unique hash string to ID the User'),
        'type' => 'varchar',
        'length' => 100,
        'not null' => TRUE,
      ),
      'active' => array(
        'description' => t('Whether the account has been activated'),
        'type' => 'int',
        'not null' => TRUE,
        'default' => 0,
      ),
      'successful_invites' => array(
        'description' => t('The number of invites responded to'),
        'type' => 'int',
        'not null' => TRUE,
        'default' => 0,
      )
    ),
    'primary key' => array( 'id' ),
  );

  // Return the Table Schema
  return $schema;
}

这是模块文件：

<?php
// $Id$
/**
* @file
* A module for encouraging users to sign up to Doodil, the hottest social
* network on the web.
*
* This module encourages users to invite their friends to sign up to Doodil
*/

define('USER_SIGNUP_CONFIRM_EMAIL',
'Hi !firstname,

You\'re just one step away from being able to invite your friends to Doodil - the hottest Social Network on the web!  Just click the link below and you\'ll be all set to earn some invite points.

!confirmlink

您发布的代码对我来说非常合适。授予这是您的安装文件的完整代码我完全确定问题出在其他地方。很可能是模块的其他文件中的语法错误。你的.install代码是100％罚款。

为什么这个架构安装文件在Drupal 7中不起作用？
