我已经使用模块为View创建了自定义字段。为了更好地在这里可视化,我简化了它:自定义域简单地生成1到10之间的随机数。自定义字段无法在视图中排序或过滤Drupal 7
我想“排序”这个随机数。
SQLSTATE [42S22]:列未找到:在“字段列表”
我奋力查找错误1054未知列“my_custom_field”不过我用浏览此功能时,收到以下错误在我的代码中。
感谢您在我的模块代码中提供的任何帮助!
这里是我的文件:
my_custom_module.info

description = Implement random number in views.
core = 7.x
files[] = includes/views_handler_my_custom_field.inc
my_custom_module.module
<?php
/**

function my_custom_module_views_api() {
return array(
'api' => 3,

}

<?php

感谢您花时间回答!我现在更好地理解逻辑。不幸的是,我不得不改变我的'更大的图片'的方法,因为这种方法不起作用。根据登录用户创建的实际自定义字段是动态的(与上下文筛选器一样)。问题是我需要多个上下文过滤器,使用它们之间的或功能,并暴露给用户使用。时间找到计划B ... – Matt
