Question

我在Drupal 7中创建了一个自定义模块.mod的目的是从后端创建一些记录，并将前端的记录显示为块。我可以通过这个模块添加/编辑/删除/显示记录。我还将此mod分配给＆＃34;内容＆＃34;块区域中的区域通过后端。但是，记录并未出现在前端。自定义构建模块的完整代码如下所示。

等待你的帮助。

Answer 1

您的＆＃39; my_custom_banner_block_view＆＃39;中的代码部分将$ output变量分配给$ block [＆＃39; my_custom_banner＆＃39;]的函数是错误的。您需要输入以下代码 -

{{1}}

＆＃39;内容＆＃39;是你的块的内容。

此外，您正在$ output变量中创建最终HTML，而您正尝试在$ block [＆＃39; my_custom_banner＆＃39;]中再次对其进行主题设置。我已经删除了你。

请检查这是否适合您。：）
