一个php codeigniter问题

codeigniter php

视图中有网页的description,keywords,contact,etc…….这些是存在数据库中的,
如何只写在一个位置就能在模板中调用?

比如说<?php echo $system->keywords;?> 就能输出关键词信息,而不用写在每个控制器里面

你可以使用 » 类库参考 » 加载器类 中的vars方法

文档地址
使用方法 在MY_controller.php中构造方法中:

<code>$this->load->vars('yourglobalvars','yourvalues');</code>
Copy after login

你的所有控制器继承 MY_controller,这样你可以在所有继承了该控制器的视图模板中使用这个变量。

<code><?php echo $this->yourglobalvars;?></code>
Copy after login

可以放在缓存里面,然后直接从缓存里面拉取

可以试试 trait,用来可复用的代码块,详细的可以看看 php手册

自定义类 然后数据库放数据 将该类设置为自动加载
参考我博客写得一篇文章
链接

直接在视图里 $this->load->view() 就可以了。
