phpcmsv9全站搜索,不限模型！

phpcms不限模型搜索的設置方法

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

簡單修改一下v9默認的搜索功能，可以不按模型搜索全站內容

下面是被修改后的search模塊中的index.php文件

<?php

      echo $v['keyword']."\n";
    }
 
    
  }
}
?>

然后在header.html模板（不在這里，就在其他的搜索框頁面）上面增加一個“不限”的搜索條件，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么搜索出來的結果就是所有模型中符合條件的數據。
