phpcms不限模型搜尋的設定方法

phpcmsv9全站搜尋,不限模型！

phpcms不限模型搜尋的設定方法

phpcmsv9全站搜尋,不限模型,今天又漲知識了。大家都知道，phpcms搜尋時按照模型來搜尋的，用了這個方法後，就可以全站搜尋

#簡單修改一下v9預設的搜尋功能，可以不按模型搜尋全站內容 

下面是被修改後的search模組中的index.php檔案

然後在header.html模板（不在這裡，就在其他的搜尋框頁面）上面增加一個「不限」的搜尋條件，將typeid對應的值為0，search中的index.html和lists.html也做相同處理，效果就出來那，這樣只要不選擇模型那麼搜尋出來的結果就是所有模型中符合條件的資料。
