显示有关项目php codeigniter的更多信息
我在mysql中有一个数据库表，它有11个实体。当用户第一次搜索项目时，“我的代码”显示5个实体，然后有一个链接供用户单击以查看有关该项目的更多信息。当用户单击该链接时，它将引导他们进入一个新页面，其中包含基于itemID单击的项目的信息。我不知道如何将实体的itemID传递给控制器。请帮忙！ 这是我的密码： 控制者：显示有关项目php codeigniter的更多信息,php,mysql,codeigniter,Php,Mysql,Codeigniter,我在mysql中有一个数据库表，它有11个实体。当用户第一次搜索项目时，“我的代码”显示5个实体，然后有一个链接供用户单击以查看有关该项目的更多信息。当用户单击该链接时，它将引导他们进入一个新页面，其中包含基于itemID单击的项目的信息。我不知道如何将实体的itemID传递给控制器。请帮忙！ 这是我的密码： 控制者： <?php defined('BASEPATH') OR exit('No direct script access allowed'); class ItemView
