Php t在会话中存储所选的筛选器选项 清除会话的重置功能

使用hook_menu（）调用tic_fetch_results（）

获取、筛选、输出结果 此示例使用了，因为它很容易随条件扩展

在会话中存储选定的值 重置过滤器

要扩展Asimov的答案，这里有一个代码示例（用于Drupal 7），它显示了用于选择节点的分类术语过滤器。所选术语存储在会话中，并在查询中用于筛选结果

您可以将其放在自定义模块中。它不需要视图或任何其他贡献的模块。 在下面的示例代码中，自定义模块的名称为tic。将tic重命名为自定义模块的名称

需要四个要素：

一个函数，用于输出过滤器、获取和输出结果

过滤形式

在会话中存储所选筛选器选项的自定义提交函数

忘了说了，但我正在开发我们自己的模块，所以我不想使用另一个模块并将链接放到另一个地方。我想把它和其他模块的功能，我自己的访问权限和其他东西放在一起。忘了说了，但我正在开发我们自己的模块，所以我不想使用其他模块，把链接放在不同的地方。我想把它与其他模块的功能，与我自己的访问权限和其他东西。
