Drupal可編輯頁面部分

Question

我需要在主頁上創建一個公司總裁可以顯示消息的區域，該消息將經常更改。我不確定是否應該爲此使用塊或某種內容類型。祕書將被分配更新信息的任務，所以我不確定我是否希望她弄糟一塊。創建新的內容類型需要在主頁中嵌入一個內容實例。主頁使用模板文件，所以我甚至可能需要添加一些PHP代碼來控制內容的顯示位置。

或者我應該創建一個自定義視圖來完成此操作？

Answer 1

我最近有一個類似的挑戰。客戶需要一種設置主頁上顯示的警報的方法。你的例子類似：

1）我不想給編輯權限編輯塊

2）只是爲了提醒創建內容類型似乎有點小題大做

的解決方案是創建一個簡單模塊執行以下操作：

1）創建一個形式輸入警報內容，並存儲在Drupal的「可變」表 （hook_admin（））

2）創建一個管理該內容頁面來存放形式 （hook_menu（））

3）定義要分配給可編輯的警報角色新的權限 （hook_perm（））

4）將存儲在變量表中的值到page.tpl （hook_preprocess_page（））

完整的模塊文件：

/** 
* 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 
*
