我有三個表格。項目，製造和這兩個ItemManufacture的連接表。 商品有ID和商品名稱。製造商有製造ID和製造商名稱。 物品製造商有物品ID和製造ID。使用Yii連接表格的Combobox篩選器CGridview
我使用Yii的CGridView控制，以顯示與項目名稱和相應的製造商名稱該商品的所有項目。我可以使用http://www.yiiframework.com/wiki/385/displaying-sorting-and-filtering-hasmany-manymany-relations-in-cgridview/
中給出的教程成功地在網格視圖中顯示這些內容。我還可以添加文本字段過濾器，如教程中給出的。 我的問題是，我想爲製造商名稱列添加組合框過濾器。 我試圖通過添加過濾器一樣，
'filter'=>CHtml::listData(Manufacture::model()->findAll(), 'man_name', 'man_name')
但它並沒有奏效。但適用於製造表格，無需任何連接。
然後我嘗試，
'filter'=>CHtml::activeDropDownList(Manufacture::model(),'man_name', CHtml::listData(Manufacture::model()->findAll(), 'man_name', 'man_name'));
它會顯示所有名稱的組合框，但是當我選擇任何名字，它不過濾輸出。而是顯示一個空的gridview。
任何人都可以解釋發生了什麼以及如何解決它？
PS：
當我打印了CHtml ::的ListData（製造::模型（） - >的findAll（）， 'man_name'， 'man_name'）在所述控制器使用的print_r，它顯示的所有名稱制成品。

我也試過這種方式。但它沒有顯示組合。 – Harikrishnan
製造表的ID字段被命名爲「id」還是「man_id」？ – A3a
是的，這是man_id和我一起都測試過，仍然沒有希望 – Harikrishnan
