drupal-6 - Drupal 可编辑页面部分

Question

我需要在主页上创建一个区域，公司总裁可以在其中显示会经常更改的消息。我不确定是否应该为此使用块或某种内容类型。秘书将被分配更新消息的任务，所以我不确定我是否希望她弄乱一个块。创建新的内容类型需要一个需要嵌入主页的内容实例。主页使用模板文件，因此我什至可能需要添加一些 PHP 代码来控制内容的显示位置。

或者我应该创建一个自定义视图来完成这个？

我最近遇到了类似的挑战。客户需要一种方法来设置将出现在主页上的警报。与您的示例类似：

1) 我不想给编辑者编辑区块的权限

2) 仅为警报创建内容类型似乎有点矫枉过正

解决方案是创建一个执行以下操作的简单模块：

1) 创建一个表单来输入警报内容并将该内容存储在 Drupal 的“变量”表中 (hook_admin())

2) 创建一个管理页面来保存表单 (hook_menu())

3) 定义分配给可以编辑警报的角色的新权限 (hook_perm())

4) 将存储在变量表中的值发送到 page.tpl (hook_preprocess_page())

完整的模块文件：

/**
 * Build the administration form which collects the following and store the values in the vars table:
 *
 * @toggle - whether or not an alert is active
 * @severity - Severity of the alert (low or high)
 * @title - The title of the Alert (usualy "Alert")
 * @content - Content to display on the homepage
 * @node - The associated Alert Node. The Read More link on the homepage will link to this node
 *
