phpcmsv9全站搜尋,不限模型！

phpcms不限模型搜尋的設(shè)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(shí)按照模型來搜尋的，用了這個(gè)方法後，就可以全站搜尋

#簡單修改一下v9預(yù)設(shè)的搜尋功能，可以不按模型搜尋全站內(nèi)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(gè)「不限」的搜尋條件，將typeid對應(yīng)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(jié)果就是所有模型中符合條件的資料。
